Performance Monitoring

Local Performance Monitoring is available only for the U-interface, when configured for a leased mode of operation. See the subsections entitled Loopback Tests, Point-to-Point Test, and Local Loopback for applicable test descriptions.

ADTRAN U-BR1TE Bidirectional Loopback

In LULT Mode, the ADTRAN U-BR1TE will execute a bidirectional loopback when performing DS0 DP loopback. See Figure 9 for an illustration of the bidirectional loopback.

Remote End Initiated LBK Tests

The U-BR1TE supports loopbacks generated from the remote unit which allows testing to be performed

without coordination with the CO or test center. Loopbacks initiated by the OCU-R front panel LBK pushbutton aid in system turn up testing or troubleshooting from the remote end.

The U-BR1TE responds to a loopback command initiated at the OCU-R as follows:

Pressing the OCU-R LBK pushbutton on the OCU-R once will initiate a loopback at the U-BR1TE toward the customer. See Figure 10. This allows data to be sent from the remote end to test the local loop and the OCU-R. This loopback is indicated by a flashing CUST LBK LED on the IDSL OCU-R and a solid LBK LED on the U-BR1TE.

Pressing the OCU-R LBK pushbutton a second time will initiate a loopback at the OCU-R toward the

4-wire DDS (CPE) interface. A solid CUST LBK LED on the IDSL OCU-R indicates a loopback at the IDSL OCU-R toward the customer equipment.

See Figure 11. Pressing the OCU-R LBK pushbutton a third time disables all current latching loopbacks initiated by the OCU-R LBK pushbutton.

If errors exist the loopbacks can help determine the source; either the local loop or the OCU-R.
