You have the PRIs set up to recover clock from the Asterisk box, is that
what you want? If so, you certainly do *not* want span=1,1,0 or 2,2,0
since that will make Asterisk think the 81C should be clock master. Are
there any telco-timed PRIs somewhere? If so, set up the PRIs on the 81C
to be CLOK INT and then use span=1,1,0,esf,b8zs and span=2,2,0,esf,b8zs
on the Asterisk box.
I'm going to assume that a big system like an existing 81C already has
the master clock set, but of course that will be a necessity if using
internal clocking.

Subject: [asterisk-users] Nortel 81C MSDL Trunking to Asterisk
TE110P,Nortel Resetting PRI Channels
We are currently working to trunk from a Nortel 81C to an
Asterisk Server 1.4 running on Red Hat Linux. We have two PRI trunks
which work with the exception of the clock slips, which is causing the
Nortel to reset the PRIs once a hour. Thanks for any suggestions.
