4. HDSL4 SYSTEM TESTING

The T200 H4TU-R provides diagnostic, loopback, and signal monitoring capabilities.

The seven front panel LEDs provide diagnostics for HDSL4 loops, DS1 signals, alarms, provisioning, and loopbacks. Refer to the Installation section for details.

The H4TU-R provides a bidirectional loopback via the loopback button on the front panel. Refer to the H4TU-R Network Loopbacks and Customer Loopbacks sections for more details.

DS1 MON Bantam Jacks

The MON jack provides a non intrusive access point for monitoring the characteristics of the transmit and receive signals at the DS1 interface point.

For example, the DS1 MON jack on the H4TU-R could be used to connect to a bit error rate tester to monitor for synchronization, test patterns, etc.

Figure 3 is an illustration of specific jack detail.

NOTE

For the MON jacks, the TX and RX indications relate to the direction of the signal to/from the CPE.
