Figure 6-10. Channel Module Testing with Local T1 Loopback or Out-of-Service T1 System

Once a system is in-service, avoid using T1 loopbacks to test individual channels, because the entire
T1 circuit is out-of-service while the loopback is active.

6.6 Troubleshooting

This section presents a general approach to troubleshooting an ACS-160 Series system, including

●

Basic guidelines

●

Typical troubleshooting procedure

●

Explanation of alerts and alarms generated by the ACS-160 Series multiplexer

Figure 6-11 shows basic trouble categories.
