I have a PRI between a Nortel 61c and a Cisco VOIP phone system. It
allows us to 4-digit dial between the two phone systems. The PRI
terminates into a 6608 gateway blade in our 6509 chassis system on one
end and a PRI card in the Nortel (loop2) on the other. Every couple of
months, I would have to disable and re-enable Loop 2 because the
b-channels get locked out. Finding out why the channels go LCKO was not
a big issue at the time because it didn't happen any more often than
the b-channels on two other PRI's.
We recently deployed 7 Cisco VOIP wireless phones in a manufacturing
area with two Cisco access points and now I have to disable and
re-enable Loop 2 every other day. I noticed on my Nortel terminal one
morning an error referencing the loop and the channel and reason 44.
Does anyone know what causes b-channels to LCKO? Does anyone else have
any experience with this type of problem??
Thanks in advance.
