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. For more details, see ‘‘Automatic
Trunk Transmission System’’ in Chapter 6, ‘‘Additional Maintenance Procedures’’.
Figur e 9-6 5 shows a typical ATMS configuration.
M/T-ANL maintenance ensures that the analog trunk’s testing function is
operating correc tly. An alarm against M/T-ANL can reduce servic e, but it will not
block it. To accurately measure perfor mance and health of analog trunks, the
TN771 should be replaced when a new circuit pack is available.
