E1 Tributary Remote Loopback
The E1 remote loopback returns the transmitted demultiplexed E1 to the receiver
multiplexer. Simultaneously, the Optimux-108 sends an unframed all-ones signal
to the E1 link.
Figure 5-16 shows the E1 remote loopback connection.
This test checks the operation of the local Optimux-108 and the connection to
the remote Optimux-108 unit.
