RBS is often times run on on AMI D4 circuits. Also, RBS is generally not run on inter-office trunks. At least that was the case a few months ago when I worked on a DMS-500. --------------------------------------------- Chad Skidmore Director of Network Engineering Northwest Nexus, Inc. http://www.nwnexus.com 1-888-NWNEXUS

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 > -----Original Message----- > From: Dan Hollis [mailto:goemon () sasami anime net] > Sent: Wednesday, September 09, 1998 5:22 PM > To: 'nanog () merit edu' > Subject: Inter-CO signaling? > > > Is there any way to determine if inter-telco links are using > robbed bit > signaling?
