M/T-ANL (Maintenance/Test Analog
Port)
The Maintenance/Test Analog Port is port number 1 on the TN771
Maintenance/Test circuit pack. This port is used by the Automatic Transmission
Measurement System (ATMS) as an Originating Test Line (OTL) or Terminating
Test Line (TTL) for test calls over analog trunks.
Figure 10-75 shows a typical
ATMS configuration.
M/T-ANL maintenance ensures that the analog trunk’s testing function is
operating correctly. An alarm against M/T-ANL can reduce service, but it will not
block it. To accurately measure performance and health of analog trunks, the
TN771 should be replaced when a new circuit pack is available.
