All IE-iMcV-E1-Mux/4 units are shipped configured as Host units via DIP
Switch #1 = OFF. The Remote unit should be set to DIP Switch #1 = ON.
Be sure to confirm that the IE-iMcV-E1-Mux/4 card is set correctly when
used.
•
The fiber transport is independent of all other ports and should be
established first. If this is not possible, a physical fiber loopback can be used
for fiber port verification. A fiber loopback will cause all connected ports to
loop back their respected data.
•
If the fiber is not connected, all E1 ports will send the all-ones,
AIS
signal.
This can be physically looped back to verify E1 port operation.
