Test XTU cabling to the DDF
1. Test one XTU at a time.
2. Activate all E1s/T1s for the chosen XTU card.
3. Check that 8 red LEDs appear on the front of the card (Netspan should also indicate
the E1/T1 alarm.)
4. Loopback each E1 in turn and check that the corresponding alarm for that channel is
cleared. (Note: the amber remote alarm is illuminated for several seconds before
clearing.)
5. Remove all jumper links and disable all E1s/T1s.
6. Repeat steps 2-5 for each XTU fitted.
Connecting the AC to the Network

1. Ensure the NMC administrator has entered all the AC shelf configuration in the
Netspan/Sitespan Server.
2. Within the AC Shelf Properties window, enter the
Port: (should be the NMC PC COM port the AC shelf is connected to)
TEI: (should be set to the pre-determined setting allocated at the planning stage)
Leave other data fields unchanged.
3. Select OK to complete the configuration process.
4. DISCONNECT THE LAPTOP PC CONNECTION TO THE AC SHELF AND
RECONNECT THE NMC CONNECTION TO THE SHELF.
5. Call in the NMC and ensure the AC shelf is seen at the NMC system. From the Shelf
Object List view, the AC shelf should be in CONNECTED and DOWNLOADING state.
Connect E1s/T1s to the Switch or Cross-Connect at the DDF

2. Connect the required E1s/T1s to the Switch or Cross-Connect using jumper cables at
the DDF.
3. All the E1/T1links should be enabled on Netspan at the NMC.
4. From the AC shelf equipment view, double click on the XTU card. This will open the
card view window. Check the E1/T1 connection to the switch is working; E1/T1-Loss
