Verify DSX-1 Connections
NOTE:
Acceptance test requires temporary loopback between the DSX-1 transmit and
DSX-1 receive connectors, either by cross-connecting DS1s at the patch panel or by
plugging a DSX-1 cable from the transmit output to the receive input connectors. The
Access Navigator can be equipped with up to 32 DS1 interfaces.
1. Establish temporary loopback or cross-connect between DS1 receive and transmit signals at the
DSX-1 interface or patch panel.
2. Turn on –48 VDC power, if not already on.
3. Verify the following front panel status indications (see Figure 6-27).
Requirement:
DS1 status indicators light green for all installed circuit cards when DS1
transmit outputs are looped back to DS1 receive inputs.
NOTE:
If status indications are incorrect, refer to Diagnostics & Troubleshooting on
.
