Port
The terminal loopback test is performed on the node source MXP, TXP, XP, or ADM-10G port. For the circuit
in this example, it is the source TXP trunk port or a client port in the source node. Completing a successful
terminal loopback to a node source port verifies that the circuit is through the source port.
Loopback on a Source-Node MXP or TXP Port, on page 12
shows an example of a terminal loopback on a
source TXP port and a client TXP port.
