EXECUTIVE SUMMARY
This test report describes the results of the Design Qualification Test andEvaluation (DQT&E) of the General National Airspace System (GNAS) MaintenanceControl Center (GMCC). The testing was conducted from April 22, 1991, throughMay 1, 1991, at the Federal Aviation Administration (FAA) Technical Center,Atlantic City International Airport, NJ.
The purpose of DQT&E was to perform phase I and phase II testing of the GMCC.Phase I consisted of verifying that Office Automation Technology and Services(OATS) contractual requirements were met. Phase II consisted of testing the LocalArea Network (LAN) interface to the Maintenance Processor Subsystem (MPS), as wellas testing the MPS, LAN, and GMCC workstation software functions. Two additionaltests were conducted to test network reliability and the effects of loading on thenetwork.
ACN-250, as Test Director, performed testing in accordance with the draft GMCCDQT&E test procedures, dated April 1991. Testing utilized version PCB0702 of theInterim Monitor and Control Software (IMCS) to monitor and send commands to thesynchronous Remote Monitoring Subsystem (RMS) simulator. The IMCS software used isresident on the ACN-250 Testbed MPS located at the Federal Aviation Administration(FAA) Technical Center. Testing also utilized commercial off-the-shelf (COTS)software packages resident on the GMCC workstations.
All phase I DQT&E requirements were successfully demonstrated during the OATS MDTevaluation prior to DQT&E testing. The phase I GMCC design is acceptable.
The phase II DQT&E requirements were successfully verified on the GMCC testconfigurations. (See the Test Verification Requirements Traceability Matrix(TVRTM) in appendix A). The network reliability test proved that allmessages/alarms from the synchronous RMS simulator were sent to the GMCCworkstations via the MPS with no data loss. The network loading test indicatedthat eight Maintenance Monitoring Software (MMS)/IMCS sessions and four TandemAdvanced Command Language (TACL) sessions could run simultaneously without systemdegradation or data loss. Test results also indicated that a GMCC workstationconnected to the MPS via a StarLAN network could run the MMS/IMCS software withonly minor problems. The only possible major problem is a lack of security,allowing unauthorized access to the StarLAN server.
Only one complete GMCC (with modems and Brouters) and two direct-connect kMultiLANAdapter to StarLAN Hub) configurations were tested. A configuration w'th fourcomplete GMCC networks must be tested before ACN-250 will recommend accepting thesystem.
At the start of testing, the GMCC network and software configurations were unclear.Datronics/American Telephone and Telegraph (AT&T) and TANDEM representativesgenerated draft configuration documentation (appendix B) during testing. Anychanges to the configuration will necessitate additional DQT&E testing.
Problems discovered during testing did not significantly impact system operation.Each problem was recorded as a Program Trouble Report (PTR). A complete set ofPTRs for GMCC DQT&E can be found in appendix C of this test report. The followinglist briefly describes the problems encountered during testing and theircorresponding PTRs:
v
a. The GMCC workstation could not access UNIX on the server because theKermit application was not functional (PTR-01).
b. A keyboard lockup sometimes occurred when a screen update was received at
the same time a key entry was made (PTR-02).
c. The PackRat application was not available (PTR-03).
d. The Back-It application did not work as expected (PTR-04, PTR-05).
e. The IMCS reports could not be printed from the network printer (PTR-06).
f. Printing MMS reports from the shared printer could only be accomplished ifthe MMS session was exited from after requesting a report (PTR-07).
g. A random error was generated when multiple data points were monitored orunmonitored (PTR-08).
h. An invalid password entry on the GMCC workstations did not prevent theuser from gaining access to the network and its applications. Although MMS/IMCShas adequate security protection, unauthorized access to the StarLAN server andnetwork, which allows access to the MPS, is not desirable. This could beconsidered a major problem (PTR-09).
i. A continuous beep occurred at workstations running two simultaneous IMCSConstant Monitor sessions (PTR-lO).
j. A 25th line message was not displayed on the GMCC workstation (PTR-ll).
k. The StarLAN server tape backup unit was not tested. Documentation on thetape backup unit was not available.
1. Failure mode testing and the useability of GMCC software applicationsshould be evaluated before a design acceptance decision is made.
ACN-250 recommends that DQT&E be repeated when a complete GMCC configuration (fourGMCC LANs connected to a single MPS) and all phase II application functions(including status board and weather) are available.

The DQT3.9 was performed in accordance with the GMCC DQT&E test procedures and wassuccessfully completed. The GMCC workstation command execution times observed wereunder 3 seconds. The alarm presentation times were under 6 seconds.
3.3.10 DQT3,10 GMCC Reporting Test.
3.3.10.1 DOT3.0 GMCC Reporting Test Purpose.
The DQT3.10 verified GMCC reporting functions by utilizing MMS/IMCS functions.
3.3.10.2 DOT3.10 GMCC Reporting Test Results.
The DQT3.10 was performed in accordance with the GMCC DQT&E test procedures and wassuccessfully completed on each GMCC workstation. No problems were observed duringthe conduct of this test.
3.3.11 DOT3,11 GMCC Loading Test.
3.3,11.1 DOT3.11 GMCC Loading Test Purpose.
The DQT3.11 verified that all GMCC workstations were capable of running independentMMS/IMCS sessions simultaneously. All workstations ran two IMCS sessions and oneTACL session. The loading effects on the network were recorded.
3.3,11.2 DOT3,11 GMCC Loading Test Results.
Test results indicate, for the configuration shown in figure 2-3, that nosignificant system degradation occurred under the loaded conditions. The GMCCperformed as expected.
3.3.12 DOT3,12 GMCC Network Reliability Test.
3.3.12.1 DOT3,12 GMCC Network Reliability Test Purpose.
The DQT3.12 verified that the GMCC network could reliably process alarms that weresent continuously from the monitored facilities. Two RMS simulators alternatelysent streams of alarm and return to normal messages to the GMCC network.
13
3.3,12.2 DOT3,12 GMCC Network Reliability Test Results.
Test results indicate that no data loss was experienced when using a networkconfiguration (figure 2-3). All alarm and corresponding return to normal messages(generated every 20 seconds) from the RMS simulators were received and displayed oneach GMCC workstation.
4. CONCLUSIONS AND RECOMMENDATIONS.
4.1 CONCLUSIONS.
All phase I Design Qualification Test and Evaluation (DQT&E) requirements wereeither successfully completed prior to DQT&E testing or satisfactorily demonstratedduring DQT&E testing. The phase I General National Airspace System (GNAS)Maintenance Control Center (GMCC) design is acceptable.
The phase II GMCC test configurations satisfactorily demonstrated the capability tointerface with the Maintenance Processor Subsystem (MPS) via the StarLAN network.The GMCC workstation software applications functioned satisfactorily. A potentialmajor problem is the lack of security on the StarLAN server that allowsunauthorized access to the StarLAN network.
The FAA-E-2875 (GMCC Type A System Specification) phase II requirement states thatup to four GMCCs may be connected to one MPS. This configuration was not availablefor testing. There are major impacts to the network configuration when expandingto the required four GMCCs. This configuration must be evaluated before designacceptance can be decided.
Failure mode testing was not formally conducted during DQT&E. Also, useability ofGMCC software was not addressed. Both of these should be considered before adesign acceptance decision is made.
Furthermore, some applications (i.e., status board, weather) required for phase IIare not yet available. These applications must also be evaluated prior to designacceptance.
At the start of testing, the configuration of the GMCC network and OfficeAutomation Technology and Services (OATS) commercial off-the-shelf (COTS) softwarewas unclear. Any changes to the network and/or COTS software that were tested willnecessitate additional DQT&E testing.
4.2 RECOMMENDATIONS.
ACN-250 submits the following recommendations:
a. Conduct General National Airspace System (CNAS) Maintenance Control Center(GMCC) failure mode testing.
b. Conduct a useability evaluation of GMCC software.
c. Repeat some or all of Design Qualification Test and Evaluation (DQT&E)when a complete configuration (four CMCC Local Area Network (LANs) connected to asingle Maintenance Processor Subsystem (MPS)) and when all software applicationsare available.
d. Conduct all recommended testing (a through c) before a designqualification decision is made.

1. Introduction
This document was produced to detail the procedures carried out in setting up theGeneral Maintenance Control Center (GMCC) system. The document includes hardware andsoftware configuration procedures and modifications, application procedures, systemdiagrams and a complete CLIN listing. The project was carried out over a six weekperiod from March 18th to April 26th 1991, at the FAA Technical Center near AtlanticCity. Assistance during the project was provided by the following individuals:
Richard Van Suetentael (FAA)Dennis Steelman (FAA)Bill Gibbons (Tandem)Tom Miller (Tandem)Phillip Hoang (FAA)Samer Salty (Martin Marietta)Julie Riches (CTA/ACN-250)Mike Jones (CTA/ACN-250)Craig Stewart (CTA/ACN-250)

2. System Architecture
2.1 System Overview
Two system configurations were set up and tested during the project. The firstconfiguration connected the OATS network directly to the MLAD computer through theNHU (Network Hub Unit). The second configuration included the Brouter hardware whichprovided a bridge between the MLAD and the OATS network. System diagrams for bothconfigurations are provided in appendices A and B.

4. Detailed Software Configuration
4.1 Workstation Software
AT&T StarGROUP Client version 3.3 (8 user)AT&T MS-DOS 3.30a Version 1.01Microsoft Windows Version 3.06530 Terminal Emulation
4.2 Server Software
AT&T StarGROUP Server version 3.3 (8 user)Unix System V/386 Release 3.2.2
4.3 Loading Procedures
It is assumed that all of the OATS software will have been pre-loaded before delivery,including the installation of the server and client StarLAN software. The followingis the sequence of tasks that should be carried out to connect and configure the GMCCsystem.
- Connect the components of the GNAS section of the system.
- Connect and configure the Brouters and AUI adapters.
- Install the StarLAN NAU card into the MLAD computer, setting the IRQ, I/OAddress and RAM address as outlined.
- Connect the MLAD to the Hub unit.
- Install the StarLAN client software on the MLAD. The procedure for this can befound in the StarGROUP document "StarGROUP Software - Installing LAN Manager". Thefollowing options should be selected during the installation:
Choose the install rather than the upgrade.Select Basic DOS client form the "Select a Configuration" menu.All software should be loaded on drive C:Accept the default directory location.Enter "WKSIO" as the computer name.Enter the primary server name as specified, including the .serve extension.Do not enable the message receiver.Do not load the network driver in expanded memory.Do not load the DOS redirector in high memory.Enter "Yes" to "Prompt to start network software on boot".Enter the NAU interface board type as AT&T Starlan 10 Network PC NAU.Enter the strap setting as they have been set up on the NAU board. Theyshould be:
IRQ - 2I/O Address - 368RAM Address - DOOOOTest the configuration.
B-10
Once installed, and with the server running and Brouters in place, reboot the MLAD.The MLAD will try to make a connection to the server. If the connection issuccessful, the message "SOFTWARE LOADING COMPLETED" should appear. The network canthen be further tested by linking to the server disk.
4.4 Parameter Adjustments
These amendments need to be made to the following files:
4.4.1 OATS Workstation
Config.sys
Add the following lines:
device-c:\tandem\kernel.sysdevice-c:\tandem\rmpcdrvr.sysdevice-c:\tandem\lan6530.sys /S4 /B4096
These files should be supplied by Tandem. The file sizes and creation dates areshown for reference.
LAN6530 SYS 15514 12-06-90 ll:10aRMPCDRVR SYS 10030 12-06-90 ll:llaKERNEL SYS 2819 12-06-90 ll:07a
Autoexec.bat
Add the following lines:
D : \lanman. dos\netprog\ql N: \\servname. serve\uD : \lanman. dos\netprog\ql LPTI: \\servname. serve\accell02
Replace 'servname' with the name of your server.
Protocol.ini
Amend the following parameter:
nsess - 7
This will allow the workstation to open three 6530 sessions and access the TandemDos partition.
4.4.2 MLAD
Config.sys
Add the following lines:
device-c:\tandem\kernel.sys
These files should be supplied by Tandem. The file sizes and creation dates are
shown for reference.
B-11
KERNEL SYS 2819 12-06-90 11:07a
Protocol.ini
Amend the following parameters:
nsess - 32
ncmds - 64
B- 12
4.5 PCT Setup
The 6530 terminal emulation program is called PCT.EXE, and should be installed on eachworkstation. The Oks 1989 version should be used. The configuration program used toset up the emulation parameters is PCTC.EXE. To allow Windows 3.0 to open threecopies of the same program with different parameter files, three directories had tobe created under the TANDEM directory on drive C: These should be called TACL, MMS1and MMS2. The PCT.EXE file was copied to each of these directories and renamedPCTTACL.EXE, PCTMMS1.EXE and PCTMMS2.EXE, respectively. The configuration programshould then be run in each of these directories to create the PCT.INI files. Thefollowing fields should be amended in the configurations:
On page 3 of 9:
HOST NAME '\acta'WINDOW NAME '\acta.$lanl.#bdl2tcl'
NB. The fields in quotes are examples only. Consult with the TANDEM engineer tofind out the local names that should be used. The window names should be differentfor each PCT session.
On page 5 of 9:
AUXI DEVICE 'LPTI'AUX2 DEVICE 'AUX2TACL'DEVICE NAME 'LANDRVR'
The AUX1_DEVICE field should be set to the shared printer (if this is not set up ora non-shared printer is entered, a 'DOS ERROR: BAD STRUCTURE LENGTH' error will occuron starting the second and subsequent windows on the workstation). The AUX2_DEVICEcan be set to a shared printer or to a file name. If set to a file name, this shouldbe different in each PCT.INI set up. The DEVICE NAME must be set to LANDRVR.
The setup can be tested outside of Windows by typing in the PCT program name in thedirectory containing the PCT.INI file. If the network is connected correctly andfunctioning, it will be possible to connect to the TANDEM machine. To end theTANDEM session, type CTRL-END.
4.6 Batch files
A batch file has to be included in each of the TANDEM directories to stop multiplecopies of the same program running. An example of the control batch file is shownin appendix G. This requires that the directory C:\LOCKS exists. The three batchfiles should be called C:\TANDEM\TACL\BATTACL.BAT, C:\TANDEM\MMSI\BAT_MMSl.BAT andC: \TANDEM\MMS2\BAT_MMS2.BAT.
4.7 Windows Environment
4.7.1 Program Groups
A program group should be created with the description "Tandem Applications" withinthe Program Manager.
B-13
4.7.2 Program Items
Three program items need to be created within the program group "Tandem Applications",one for each of the programs in the TANDEM sub directories created (ie. TACL, MMS1and MMS2). The descriptions and command lines should be:"Tandem TACL Window" - "C:\TANDEM\TACL\BATTACL.BAT""Tandem MMSl Window 1" - "C:\TANDEM\MMSI\BAT MMS1.BAT""Tandem MMS2 Window 2" - "C:\TANDEM\MMS2\BATMMS2.BAT"
4.7.3 PIF Files
PIF files need to be created to control the running of programs inside Windows,including the batch files. These PIF files are created and modified using the PIFeditor found within the Windows environment. A total of six PIF files will need tobe created. Example are shown for the TACL batch file PIF and the TACL PCT PIF:
TACL batch file PIF: BATTACL.PIF
Program Filename: C:\TANDEM\TACL\BATTACL.BATWindow Title: TACL WindowStart Up Directory: C:\TANDEM\TACLMemory Requirements: KB Required 128 KB Desired 640Display Usage: WindowedExecution: BackgroundClose Window on Exit: YesBackground Priority: 25Foreground Priority: 50EMS Memory: KB Required 0 KB Desired 1024XMS Memory: KB Required 0 KB Desired 1024Uses High Memory Area: YesVideo Memory: TextMonitor Ports: High GraphicsEmulate Text Mode: YesAllow Fast Paste: Yes
TACL PCT PIF: PCTTACL.PIF
Program Filename: C:\TANDEM\TACL\PCTTACL.EXE
All other parameters should be the same as above. For the MMSI and MMS2 PIF set up,amend the First three fields as appropriate. If the network and TANDEM applicationsare connected, it should now be possible to run the 6530 emulation from within theWindows environment.
4.8 Memory Management
This section is still to be completed.
4.9 Machine Names/Addresses
The following workstation names were used:
GMCC21, GMCC22, GMCC2G, GMCC23, WKSIO
B-14
4.10 Printer Configuration
The printer used was the Accel-500. StarLAN 3.3 contains a printer driver for thisprinter. The printer should be set up from within Control Panel. The AMT ACCEL-500on LPTl: should be selected and made active. The Network option should then beselected. Select the device LPTl: and type in the name of the shared printer nameon the server in the PATH field eg. \\04800368.serve\accellO2, and select connect.This will then redirect any output sent the port LPTl: to the server, which shouldthen ne printed out on the printer attached to the server.
B-15
5. Non Standard Configurations
All components and configurations should be agreed before document release.
6. Aplication procedures
6.1 System Start Up
The system should be brought up in the following order:
- Make sure that The Tandem machine is fully operational.
- Start the OATS server and switch on the printer. The machine will automaticallyboot itself intu UNIX when powered up. This will take t a few minutes. When the'Login:' prompt appears, proceed to the next step.
- Start the MLAD computer. The machine will automatically load the network softwareand start the MLAD software.
- Start the windows and applications on the Tandem. The MLAD will display all openwindows and sessions.
- Start the OATS workstations. These will load the network software and startMicrosoft Windows.
The system should now be ready for use.
6.2 Tandem Applications
The Tandem applications (MMS and TACL) are available through Microsoft Windows onthe OATS workstations. They can be accessed through the 'Tandem Applications' Iconwithin the 'Program Manager". By double-clicking on this Icon , the contents willbe displayed. There are two MMS windows available and one TACL windcw. To run oneof the options, point to it with the mouse and double-click on the option. Thiswill open a window into the selected application. To close these applications,press Ctrl-End. If the same option is selected before the window is closed amessage will appear in a window saying the application is already running. It isnot possible to exit Windows while any of the Tandem applications are running.

Documentation for testingof MULTILAN/STARLAN
conducted at the F.A.A.Technical Center
During the weeks starting on March 18,1991 and ending onApril 17,1991 , testing was conducted at the Technical Center todetermine the viability of utilizing the A.T.& T. OfficeAutomation Technology Systems (OATS) equipment to access TANDEMbased applications via the MULTILAN NETBIOS gateway product.
The purpose of this testing was to determine if this'off-the-shelf' hardware/software could be utilized to providethe required connectivity for the MCC GNAS project. The intentof this document is to provide sufficient detail of the TANDEMhardware/software configuration to enable the reader to replicatethe tested configuration.
This document will only briefly describe the STARTLANcomponent of the hardware/software LAN environment. The STARTLANLAN environment will be described in a separate document preparedby the A.T.&T. sub-contractor, DATRONICS.
This document assumes that the user is familiar with theTANDEM host application, PATHWAY, PATHCOM, SCF, and otherutilities. If further information is required in these areas,please reference the appropriate application manual.

During the first three weeks of our testing, we weregiven only one A.T.& T. STARTLAN 10 PC LAN adapter forthe two MLADS. Although other PCs, with STARTLAN 10adapters installed were available, we were not permitted touse them. This severely limited the scope of our testduring that period.
Limited to one STARTLAN 10 PC adapter card, we wereable to test connectivity to the TANDEM in only the singleMLAD configuration. Using the single MLAD, we testedconnectivity in two configurations:
1. Configuration #1 (pg. 3) consisted of a local LAN setupwith the MLAD gateway attached directly to the HUB of theSTARLAN.
2. Configuration #2 (pg. 4) included two A.T.&T.communication routers, called BROUTERs. The two BROUTERs'-ere connected via modems to an analog circuit configured tosimulate a leased circiut in a Wide Area Network (WAN). TheBROUTERS were employed to provide a LAN communication bridgefrom the LAN (remote) to the MLAD gateway (local).

ovezviev (cont.)
Later, we were supplied with five additionalworkstations. We extracted the STARLAN 10 adapter from oneof the five workstations and placed the card into the secondMLAD. This limited our second GNAS configuration to three(3) CLIENTs and one (1) DISK SERVER.
The anticipated GNAS LAN configuration is expected toconsist of four (4) CLIENT workstations and one (1) DISCSERVER. Each Air Route Traffic Control Center (ARTCC) wouldsupport a maximum of four remotely located GNAS MCC LANsetups. Additionally, the possibility exists for a localLAN setup, know as the AMCC, to require access to theTANDEM.
We recomended that the FAA perform testing with aconfiguration containing the full range of devices expectedto be supported by the maximum configuration. Due to lackof available equipment, the FAA decided to process with thetesting using the available equipment.
TANDEM Connectivity Components
The 5600 Ethernet controller, the controller cablewhich runs from the controller to the EMI patch panel, thetranceiver cable which runs from the EMI patch panel to theTRANSCEIVER, the transceiver, and the ETHERNET coaxial cableto the 3COM 503 cards inside the two MLADs had already beeninstalled by the TANDEM CE proir to our arrival.
In both MLADs, the 3COM 503 card was jumperedaccording to the factory settings. The factory setting forthe I/O base address is 300h. The factory setting for thememory base address is 'disable'. All software options wereallowed to assume the default settings.
All STARLAN 10 adapter cards were installed with an I/Obase address of 368h. The memory base address was set toDOOO.
The 3COM adapter assumed IRQ 4 and the STARTLAN 10adapter was set to assume IRQ 2.

1. Nine A.T.&T. 386 workstations. Two (2) were designatedas the LAN DISK SERVERs, and the other seven (7) were set upas LAN CLIENTS. We were informed that each GNAS MCC wouldcontain one SERVER and four CLIENTs, so we would only beable to configure one complete GNAS MCC site.
2. Two A.T.&T. BROUTERs.
3. Two STARLAN HUBs.
4. Two sets of cables for connecting the BROUTERs to theHUBs.
5. One STARLAN 10 LAN adapter card for each of the nineworkstations.
6. Two MLADs each eqiuped with a 3COM 503 adapter forconnection to the TANDEM based 5600 LAN controller.
7. Two STARTLAN 10 LAN adapter card for the MLADS. EachMLAD should be able to support two NETBIOS LAN adaptercards. In the case of the STARTLAN cards, this would limiteach gateway (MLAD) to supporting 32 names and 64 sessions.We tested with only one STARLAN 10 adapter per MLAD,limiting each MLAD to 16 names and 32 sessions.
Since we were testing with a limited subset of thedevices expected in the maximum configuration, the FAA wasreluctant to pass the system without specifying that theDesign Qualification Test and Evaluation (DQT&E) washampered by lack of equipment.
However, given the results of our testing, we do notanticipate problems as more GNAS MCC sites are added. Thecommunications circuit bandwidth (@19,200bps) shouldthrottle the activity for each GNAS MCC LAN added.

NLAD Configuration Notes
The gateway name in the MLADS command must match thename specified in the TANDEM SCF 'ADD GATEWAY' commanddiscussed later (i.e. -g#PITaO or -g#ACYaO in our exampl3s).
The -S32 and the -C64 must match the 'nsess' and the'ncmds' entries in the \LANMAN.DOS\DRIVERS\STAR10\PROTOCOL.INI file installed on the MLAD as part of the AT&TSTARTLAN configuration. Note that the 'nsess' entry (numberof sessions) in the PROTOCOL.INI file will effect the numberof sessions which can be established via the MLAD. Each PCuses some of these sessions for LAN based functions.
At one point, we were receiving 'CSS error 4' from theemulator (PCT) while attempting to start a third window viathe WINDOW 3.0 manager. Increasing the number of sessionson the workstation adapter by incrementing 'nsess' solvedthe problem.
The C:\TANDEM subdirectory contains the G21 release ofthe EM6530 product. The diskette containing this release ofEM6530 should be delivered with the MULTILAN product.
Be sure to use the KERNEL.SYS contained with the G21release (not the old KERNEL.SYS contained on the MULTILAdiskette). The older release of KERNEL.SYS included on theMULTILAN diskette is not compatible with the G21LAN6530.SYS. This is important when installing the driverson the LAN workstation.
The MLADS.EXE was taken from the SUT delivered with the5600 controller. The version we used contained a version ofT9377C2OA16feb9OA16feb90. This version number will alsoappear as the banner on the MLAD once started.

LAN Based Workstations
After the installation of the AT&T STARLAN networksoftware on the workstation, the CONFIG.SYS contained thefollowing:

TANDZM device drivers
The KERNEL.SYS device driver creates a multitaskingenvironment for the PC based software. KERNEL.SYS must beloaded before RMPCDRVR.SYS and LAN653O.SYS.
The RMPCCOM.SYS device driver establishes a sessionbetween the PC and the TANDEM based MultiLan ResourceManager (MLRM) via the session associated with the ZHME1application name.
The session is used by RMPCCOM for logging onto thesystem. LAN6530 also uses this session to establish dynamicand static windows (note: addition of each window results inaddition of an application name to the MLAD resident LANadapter card.
The session is established when the named resource isutilized i.e.- an application is run against the addedwindow).
The LAN6530.SYS device driver establishes multipleterminal emulation (PCT) sessions (depending on the /Sxparameter) via dynamic or static windows.

STARTUP
You should have a Subsystem Control Process (SCP)running to support your SCF interface. If one has not beencreated, you can start one as follows :
stop SZNETSCP/NAME $ZNET,PRI 150,NOWAIT,CPU l/2;autostop -1
Start the TLAM Manager. This NonStop process pairprovides the internal programmatic interface forconfiguration and network management of TANDEM LAN accesssoftware communications subsystems. There is only one MLMANprocess pair per TANDEM system and it's PPD name shouldalways be SZLMG.
stop SZLMG
MLMAN/NAME $ZLMG,PRI 198, CPU 3,NOWAIT/2
Start a Multilan Resource Manager (MLRM).
stop SZMRMMLRM/NAME $ZMRM,PRI 197,CPU
Use Subsystem Control Facility (SCF) to add andinitiate the subsystem objects.
SCF/IN SSYSTEM.MULTILAN.DOMAIN/
Where the file DOMAIN would contain commands toaccomplish the following for each GNAS. For exact filecontents see:
\ACTA.$system.Multilan.domain which is secured fornetwork access ).
allow all errors ! allow for error conditions
start line $laml ! insure line is started
B-39
STARTUP (continued)
During our testing we assumed that each GNAS would beconsidered one domain, so we named the DOMAIN after thePittsburg GNAS (PIT).
add domain $laml.#PIT,default
We were only supplied one LAN adapter card, so we named
the gateway after adapter zero in that gateway.
add gateway $laml.#PITAO,type mlad,domain #PIT
We assumed the wokstations would be named accordingthe GNAS in which they were contained.
add WS $laml.#PITl,domain #PIT
Then we added three window for each workstation. Onefor TACL, one for MMS, and one for MMS.
add window $laml.#PITIMCs,WSname #PIT1delay 2add window $laml.#PITIMMs,WSname #PIT1delay 2add window $laml.#PITiTCl,WSname #PIT1delay 2
Note : Once we added the BROUTER we noticed that theNethbios Add Name requests were not being handled
quickly enough, so we added a 2 second delaybetween each add. This seemed to be sufficient.
\new
SOFTWARE ON the TANDEM (host)
DOMAIN commands (continued) :
We then added the remaining windows with the followinSCF
commands:
add WS $laml.#PIT2, domain #PIT
B-40
add window $laml.#PIT2MCs,WSname #PIT2delay 2add window $laml.#PIT2MMs,WSname #PIT2delay 2add window $laml.#PIT2TCl,WSname #PIT2add WS $laml.#PIT3, domain #PITdelay 2add window $laml.#PIT3MCs,WSname #PIT3delay 2add window $laml.#PIT3MMs,VSname #PIT3delay 2add window $laml.#PIT3TCl,WSname #PIT3delay 2add WS $1aml.#PIT4, domain #PITadd window $laml.#PIT4MCs,WSname #PIT4delay 2add window $laml.#PIT4MMs,WSname #PIT4delay 2add window $laml.#PIT4TCl,WSname #PIT4delay 2
Now that objects were added, and the application names
weresuccessfully added to the MLAD adapter, we initialized the
objects by isssuing the start command.
start line $laml,sub all
\new
SOFTWARE ON the TANDEM (host) :
Adding the application windows :
We wanted to have applications running against thewindows, so we added the application items using PATHCOM.
Since the application code we were using supported onlya four TCP configuration, we added the each 'terminal'to the TCP with the same number as the workstationnumber. This was done intentionally so that a problemimpacting a particular TCP (i.e.-CPU crash) would onlydiable one workstation at the GNAS. A given workstation
number at each GNAS would be associated with the Mn-TCPon the MPS (where n is the terminal number).
PATHCOM /in \ACTA.$system.mmslan.LANCONF/ $MMS
B-41
Where the file LANCONF would contain the followingentries for each GNAS MCC :
Set up the default values to be used for both MMS and MCS
applications.
SET TERM DISPLAY-PAGES 5SET TERM INITIAL MMSINITSET TERM TMF ONSET TERM AUTORESTART 0SET TERM TYPE T16-6530
Declare the individual terminals to support the MMSapplication.

B-43
SOFTWARE ON the TANDEM (host) :
Adding the application windows (continued)------------------------------------------
Then we started the sessions with the following command.
PATHCOM/ in STARTWIN/ SMMS
Where STARTWIN would contain the following commands foreach GNAS MCC :
start term PITlmmsstart term PIT2mmsstart term PIT3mmsstart term PIT4mmsstart term PITlmcsstart term PIT2mcsstart term PIT3mcsstart term PIT4mcs
A TACL process was then started as follows for each GNASMCC:
tacl/in $laml. #PITltcl,out $laml. #PITltcl,name$PITtl,nowait,pri 150,cpu 3/2
tacl/in $laml. #PIT2tcl, out $laml. #PIT2tcl,name$PITt2,nowait,pri 150,cpu 2/3
tacl/in $laml. #PIT3tcl,out $laml. #PIT3tcl,name$PITt3,nowait,pri 150,cpu 0/1
tacl/in $laml. #PIT4tcl,out $laml. #PIT4tcl, nameSPITt4,nowait,pri 150,cpu 1/0
We found that it was extremely useful to use the namingconvention shown in the above examples. Each nameidentified the domain, window, workstation, and applicationwhenever a problem occured.
The actual startup files we used in our testing can befound on \ACTA.$SYSTEM in the MULTILAN and MMSLANsubvolumes. The MNSLAN subvolume contains the startup andconfiguration used for the PATHWAY application. TheMULTILAN subvolume contains the remaining files (includingthis file).
B-44
SOFTWARE ON the TANDEM (host):
Adding the TANDEM SERVER environment:
The TANDEM system administrator created a user id underthe MMS user group called IMMS.GMCC' and gave it a passwordof 'GMCCUSER'.
The TANDEM server environemnt was to be located in\ACTA.$DATA2.DOSDISK subvolume. Logged on as 'MMS.GMCC' andin the $data2.dosdisk subvolume, we created the twonecessary files by entering the following FUP command:
FUP/in Saystem. sysl7.MLSRVFUP/
This created the DOSENT and DOSACC files needed to managethe DOSDISK.
The STARTSRV file contains the startup info we used for theMultiLan Server (MLSRV).
The STARTSRV file contained the following:
MLSRV/name Smsrv,in CMDS,cpu 2,pri 160/
where CMDS contains:
backupcpu 3memory 2500000lan adapter $laml.#PITa0.0 1share dosdisk - \ PWD /rwcshare PITIdos - \PIT1 pswdPl /rwcshare PIT2dos - \PIT2 pswdP2 /rwcshare PIT3dos = \PIT3 pswdP3 /rwcshare PIT4dos - \PIT4 pswdP4 /rwcshare guard - GUARDIAN /1800share sread - SPOOLERREAD Sspls /US7share swrite - SPOOLERWRITE $s.#lp /us7 /$splscache files 10 read
B-45
SOFTWARE ON the TANDEM (host):
Adding the TANDEM SERVER environment:
At the workstation we added the following commands tothe AUTOEXEC.BAT file:
RMPCCOM SET HOST \ACTARMPCCOM LOGON @\ACTA MMS. GMCC, GMCCUSER
net use f: \\acta msrv0l\dosPIT pswdPlnet use g: \\actajmsrvol\guardnet use h: \\acta msrv0l\sreadnet use lpt2: \\acta msrv0l\swrite
On the first workstation we did a 'net use' on the'dosdisk'sharename. We then created the subdirectories tobe assigned to each workstation i.e.-\PIT1,\PIT2,\PIT3,\PIT4) using the MKDIR command.
We assumed that each workstation would have a uniqueand separately secured DOS partition. If you decided toallow all workstations to share a single DOS partition, youcould specify the 'net use' as follows:
net use f: \\acta-msrv0l\dosdisk PWD
B -46
Missing Software:
During the Memphis GNAS MCC testing, an addition wasmade to the I.M.C.S. software to allow for a WSPTPconnection to a BORLAND Turbo C program running on one ofthe workstations. This software combination is refered toas the 'status board'.
I requested this software from the FAA people at thetechnical center. Joe Salvatore, of the FAA, supplied mewith some of the P.C. source code. The diskette containingthe software was unreadable in certain sectors, and , as aconsequence, the TANDEM TAL WSPTP application could only bepartially restored.
I then requested that Jay Jones send me a copy of thissoftware from Memphis. Jay agreed to do so. I have not yetreceived the tape.
The 'status board' software will have to be tested atlater date.
