faceplate XMIT B connector.
Verify that the call is still established over the primary link.
Reconnect the link ST optical connector into the XMIT B
connector on the Fiber Remote Multi-IPE Interface faceplate.
Action
Check the status of the fiber-optic link by executing the D S
command from the MMI terminal.
Make sure that both the primary and the redundant links are
functional without an alarm condition on the Fiber Remote
Multi-IPE Interface faceplate.
Establish a call from the Remote IPE to the local site.
Refer to "Voice calls" (page 105)
Assuming that the traffic is carried by the primary link, switch the
link to the secondary by executing the Set Link command S L B
to select the redundant link B using the MMI terminal.
Verify that the call is still established over the secondary link.
Execute the Set Link command S L A to select the primary link A
