Each port can be set separately.
Uplink Local Loopback in the Optimux-106
The Uplink local loopback returns the transmit signal of the active Uplink interface
to the input of the receive path. Simultaneously, the local Optimux-106 sends an
unframed all-ones signal to the uplink.
Figure 5-13 shows the Uplink local loopback connection.
When this loopback is activated, the equipment connected to the local
Optimux-106 tributary must receive its own transmission.
This test checks the operation of the local Optimux-106, and the connections to
the equipment attached to the tributary interfaces.
