TCTE Source Testing
Verify that the system responds correctly when a valid SDH signal is sent, and then
add errors and alarms and check again that the system responds correctly to this new
stimulus. The following figure illustrates the test setup for TCTE Source testing.
Introduction
The following procedure gives an example of testing a TCTE source which
originates a VC-4 link over STM-1. In the procedure a valid SDH signal is sent from
the OmniBER to the TCTE Source and the output of the Source is monitored in the
OmniBER Receiver for correct TC-APId (access point identifier) and absence of
alarms.
