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 page 15-1.
