Inter-CO signaling?

Thu Sep 10 17:47:04 UTC 1998

Try making an ISDN call from one to the other at a 64k rate.  If you can
get through then there are at least some trunks setup as ESF B8ZS clear
channel.  I suspect that they are probably some older trunks running AMI
D4.

The other thing you could do is just ask them.
