TIE-TRK (Analog Tie Trunk)
A tie trunk port can also be administered as an access endpoint which is a
non-signaling channel with a voice-grade data bandwidth. Tie trunk maintenance
employs up to 6 tests, depending on the hardware involved, to monitor the
operating condition of the trunk and its connections. These are described in the
following sections on each test. The port must be idle for these tests to run. If an
incoming call seizes the port while a test is in progress, the test aborts and the call
proceeds (except for TN497).
Additional in-line testing is performed whenever a call is in progress, logging
errors that occur during operation. You can reproduce these types of errors by
making a call over the trunk and then checking the Hardware Error Log.
By making translation and cross-connect changes, circuit packs (except for
TN497) can be configured for back-to-back testing, also known as connectivity
testing. Port operation is tested by connecting two tie trunk ports together in
either E&M or simplex modes. See the section
