Remote Loopbacks in Optimux-106
You can set two types of remote loopback connections in the Optimux-106 unit:
• T1 remote, which is set for each T1 interface separately, from the terminal
• Uplink remote, which can be set from the terminal.
T1 Remote Loopback in Optimux-106
The T1 remote loopback returns the transmitted demultiplexed T1 to the receiver
multiplexer. Simultaneously, the Optimux-106 sends an unframed all-ones signal
to the T1 link.
Figure 5-14 shows the T1 remote loopback connection.
This test checks the operation of the local Optimux-106 and the connection to
the remote Optimux-106 unit.
