Restoring shelf connections
1. Remove the test equipment and connecting cables.
2. Replace the Shelf covers and the protective cap on the coupler.
3. Do not remove the Sitespan connection at this time.
Entering Test values into Netspan
The values of the TX Transmit and RX gain must be set into the Netspan at the Network
management Centre before the backhaul is connected to the CT, failure to do this results in
the TX power and RX sensitivity values being overwritten by the value stored in the Netspan
Server.
Connecting CT, AC and NMC
At this point, ensure the NMC has the site equipment created in the master database and the
V5.1 interface activated. It should show an alarm on the E1 connection to the CT shelf.
1. Contact the NMC administrator, and pass the CT shelf Transmit Power and Receiver
Level settings to the administrator for updating the master database.
Warning: When Netspan is reconnected to the CT the values of the TX and RX
levels stored at the NMC will be written to the SC of the modem shelf and Netspan
should not be reconnected until the NMC has updated its database with the correct
Transmit and receive level settings.
2.
The CT shelf connected to the LAPTOP should be in ‘UNCONNECTED’ state. This is
because the shelf is expected to get its data from the remote management system.
3. Reconnect the E1/T1 links to the CTUs/DTUs.
4. At the AC Connect Netspan backhaul to the NMC. If using a router fit RS232 9 way
to Async RJ45 adapter to the Netspan port used to backhaul to the server. Connect Sitespan
Port 1 (AC Backplane) to Management Network (ports allocated on Cisco Router).
5.
Call the NMC and ensure the commissioned shelf is in ‘connected’/ ‘downloading’
state and the E1/t1 alarm on the CTU is cleared.
6.
Remove Modem card and check that the alarm is seen in Netspan’
