5.3 MaintenanceThe following loopbacks are available for maintenance and fault isolation:
Line BU main card
RemoteLPB
LocalLPB
PayloadLPB
Fig. 5.5 Functional Diagram Loopbacks
• Remote (E1) loopback transmit the received 2M-stream back to the line, withoutany framing actions. This loopback is used to check the E1 lines.
• Payload loopback transmit the payload of the received 2M-stream back to the line,using the framing options as configured for the port (e.g. CRC calculation, Alarm bithandling etc.) The timing of the transmitted 2M stream is Jitter attenuated. Thenetwork to check the path to the E1 interface including the E1 interface itself usespayload loopback.
• Local (E1) loopback replaces the incoming 2M stream, with the transmitted stream.Local loopback is used to check a full WALKair path including the air link.
When in loopback, the LED indicator will show as follows:

6 Performing System Test
6.1 GeneralThis section describes the types of the loopbacks supported by the system. Thepresence of a loopback is considered as an alarm with Warning severity (seeSection 3.2.4). When there is a loopback on a certain port, the Telecom LED blinks inyellow color.
Note:• Loopback functionality remains active until it is disabled.• Loopback cannot be performed on port I disable mode.
6.2 Loopback TypesLoopback local (E1 LBK LCL)
Local loopback disconnects the receive lines from the receiver. The data provided bythe system interface is routed through the analog receiver back to the system interface.This loopback is used to check the FALC.
Loopback remote (E1 LBK RMT)
In remote loopback, the clock and data recovered from the line inputs are routed backto the line outputs via the analog or digital transmitter. This loopback is used for theremote side to check itself.
Payload Loopback (E1 LBK PYLD)
Payload loopback will loop the data stream from the receiver section back to thetransmitter section. The looped data will pass the complete receiver including thewander and jitter compensation in the receive elastic store. Instead of the data an AIScould be sent to the system interface.
Channel Loopback (E1 LBK CHAN)
Single channel loopback loops one channel at a time from the system PCM input to thesystem PCM output. During channel loopback an idle channel is transmitted to theremote end in the corresponding PCM channel.
6.3 Setting LoopbacksLoopbacks are set using the System Tests menu.

9 Software DownloadIt is possible to download new software versions to a BU-BS and BU-TS through alocally connected LCI. Downloading does not interrupt service. Software is resident ona Flash memory chip on the BU. Each Flash chip contains two sections: a primarysection and a backup section.
Software download is activated using a special script file, supplied with every newversion. The script file downloads all system software to the backup portion of theFlash. Once the software download is successfully completed, the user can switchbetween the active part of the Flash and the backup part (which has the new software).
Õ To download software to the backup area:
1. Activate script file option from ProWin or ProComm by pressing Alt F5, “WindowsASPECT Run Window” is presented.
2. Choose the appropriate script file named “load.wax”. The note field presented atthe top of this window displays the script description. Check that this is the SWdownload script for the appropriate version (currently 2.07). Click <OK>.
3. “WALKair program Loader” window is presented. Choose the Download files (with“.s19” suffix) location and choose required baud rate (57,600 is recommended).Click <OK>.
4. The loading process starts. LCI screen is starting to appear. A “Send New ASCIIFile” window appears for each component loading (7 for BS or TS). Multiple pointsdisplayed on the LCI indicate that the BU is still active.
5. The download process ids logged in the log file named:ProWin/capture/download.cap
Note: In case a checksum error appears during the download (can be detected vialog file or via version information), click once on the “running man” icon.Activate the script file again with a lower baud rate.
Õ To toggle between the current and backup software versions:
1. From the Main Menu, type 2 <Enter> to access the Maintenance Managementmenu, shown in Fig. 9.1.
