Card Behavior
The SDH terminal port loopbacks can either terminate or bridge the signal. TXP terminal loopbacks are
terminated as shown in the following table. During terminal loopbacks, if a port terminates a terminal loopback
signal, the signal only loops back to the originating port and is not transmitted downstream. If the port bridges
a loopback signal, the signal loops back to the originating port and is also transmitted downstream. Client
card terminal loopback bridging and terminating behaviors are listed in the following table.
AIS signal is not injected if the signal is bridged. If the signal is terminated, an applicable AIS is injected
downstream.
