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. --------------------------------------------- Chad Skidmore Director of Network Engineering Northwest Nexus, Inc. http://www.nwnexus.com 1-888-NWNEXUS

Is there any way to determine if inter-telco links are using robbed bit signaling? Eg from GTE to USwest in the Seattle area.
I suspect RBS may be causing lots of v.90 problems in GTE country in Seattle. But id like to know how to confirm this. And just maybe, get it fixed.
