1 GENERAL

The operation of the DM 8 Multiplex Equipment is controlled using theService Terminal via the service interface. With the Service Terminal, thebasic equipment settings can be set into the non-volatile memory, service functions, e.g. loop-backs, can be performed, or the state and alarmdata of the equipment can be read, etc.

If the service interfaces are connected into a bus and the buses furtherinto a service network by means of the data channel, all equipment connected to the bus or network can be remote-controlled from one pointusing the Service Terminal (or the TMS Transmission Management System, see the corresponding operating handbooks).

All the transmission management functions which can be performed withthe Service Terminal are dealt with in this description. The functions aremenu based and the menus have 1...4 levels.

The service menus of the equipment are accessed using the Service Terminal menu Select operation.

3 Reset local cancel

Cancellation of the above function.

4 Identifications

Displays the equipment identifications. Some of the identifications canbe changed by the user.

5 Controls (temporary)

Controls (loop-backs etc.) to be used temporarily e.g. in fault location.

6 Settings (permanent)

Settings by means of which the equipment is controlled permanently tocertain operatingstates. They arestoredinto a non-volatilememoryandthey are not removed by power outages.

7 Measurements

Measurements performed by the equipment itself without measurementinstruments. (In the DM 8 the supply voltage measurements).

8 Statistics

For reading and resetting the statistics compiled by the equipment.

9 Testing

Tests performed by the equipment itself.

10 User privileges

Possible fault or state messages:

*DM8 ABC (OK) or*DM8 ABC (A) or*DM8 ABC (AS) etc.

Main system:

The incoming main system signal is missing.

-no incoming 8M sig.

The frame alignment of the main system signal is lost.

-frame alignment lost

The incoming main system signal is the AIS

-AIS 8M

The error rate of the incoming main system signal is worse than the setthreshold value 1E-3 or 1E-4.

-BER > 1E-3 (or 1E-4)

The far-end alarm is received (Bit B11 of the frame structure).

The equipment has detected a fault in the memory test.

-memory fault

The equipment processor (CPU) has been reset or some other similarmalfunction. This fault message is obtained via the TMS only.

-eq. reset

The equipment has detected a fault in itself.

-fault in eq.

Tributary 1 (2, 3 or 4):

The incoming tributary signal is missing.

-no incoming 2M sig.

In addition, the tributaries provide some fault and state messages thatcorrespond to those of the main system.

10,1 Password for privileges

When the password is known and one wishes to change protected functions, the password can be given here whereupon the protection is removed for the set period of time. The equipment prompts:


Write e.g.:

10,2 PIN for privileges

When the PIN signal is used for removing the protection, the pin c1(PIN)of the service connector P1has tobegrounded, e.g. topin b1. Connect thePIN to ground momentarily when the equipment prompts:

Ground local PIN

This method can always be used even though also a password were in use(or if it has been forgotten).
