the ags+ or CGS is doing clocking, I forgot to list the command in my email. I just tryed something else. I plugged a standard 2500 V35 DTE cable to the CAB-VCF and connected the ags+ to a 2501. The interfaces came up/up and stayed that way. I may have 2 bad CAB-SS-V35MT's, or a bad port on the WIC-2T. tim Tim Medley - CCNP+Voice Network Architect VoIP Group iReadyWorld 704-943-3615 - Phone 704-943-3660 - Fax 877-6-iReady - Helpdesk -----Original Message----- From: Jim Brown [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 03, 2001 10:44 AM To: Tim Medley; [EMAIL PROTECTED] Subject: RE: AGS+ crossed over to 2610, Serial cable length issue?

[7:10810] I've finally decided to sit down and try to troubleshoot what I thought was a faulty serial port on my AGS+. I have a 2610 with a WIC-2T connected to my AGS+ via a CAB-SS-V35MT and a CAB-VCF. The CAB-VCF is from pacific cables and is a 26pin DCE to a V.35 winchester cable. The CAB-VCF is 6 feet long and the CAB-SS-V35MT is 10 feet long; so I have a 16 foot crosover cable. When I cable the two routers together and just configure a simple point to point connection, with the following config: AGS+ int s2 ip address 100.100.100.1 255.255.255.252 encap ppp no shut 2610 int s0/0 ip address 100.100.100.2 255.255.255.252 encap ppp no shut The serial interfacces come up/up but then after a second or two line protocol goes down on both sides and they become up/down. I thought the AGS+'s serial interface was bad (I had a bad applique a while back). So I moved to a different interface on the AGS+, same situation. I then decided to try a different router, I replaced the AGS+ with a CGS, and I got the same results. I now think the issue is with the cable. a) I could have a bad cable. b) the cable I have could be two long. I have replaced the CAB-SS-V35MT, with no luck. What kind of issues would I see if the cable was too long? Would I see the issue I am experiencing? I'm getting ready to call Pacific Cable and order another CAB-VCF. tim Tim Medley - CCNP+Voice Network Architect VoIP Group iReadyWorld 704-943-3615 - Phone 704-943-3660 - Fax 877-6-iReady - Helpdesk Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=10815&t=10815 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
