DSX MON, Tx to Customer

The Rx of the BERT receives data from the TX MON jack (Figure A-1). This data has a monitor

jack impedance of 432 ohms and comes from the Backplane Network T1 DSX (the data that

would go toward the customer). The

BERT TX jack is not used. This test is non-intrusive.

NOTE

Provision the T1-OR/NIU for the Out-of-Service Maintenance ser-

vice state when performing intrusive bantam jack testing.
