Re: Frame-Relay Problem [7:41250]
Sean brings up a good point to check the maximum clock rate of your module. I've seen more than 1 person try to use the A/S module for 1.544Mbps However, the A/S module that he refers to supports a max of 115.2Kbps in async mode and when put into sync mode supports a max of 128Kbps. This module you speak of (NM-4T) should support up to 8Mbps on a single interface or up to 2Mbps on all 4 interfaces at the same time. (just to be sure I checked Cisco's site on that module and here's what I found: The 4-port synchronous (sync) serial network module (NM-4T) has four DB-60 ports and provides a data rate of 8 Mbps on port 0, 4 Mbps each on port 0 and port 2, or 2 Mbps on all four ports simultaneously. The NM-4T network module supports only sync mode. http://www.cisco.com/warp/public/107/hw_4t.html So you clockrate shouldn't be a problem at 64Kbps. It seems that most of any suggestions I could make have been covered here (framing, frame-relay switching, etc). I guess I would just start at layer 1 and work up from there. i.e. make sure all cables, connectors and even serial interfaces on the routers are good, then proceed up to layer 2 with debugs, etc HTH, Mike W.

Re: Frame-Relay Problem [7:41250]
I have already done all steps except the first one. Its a good point and I'll check that.

RE: Frame-Relay Problem [7:41250]
Do you have another router to connect to the 3660? This would give you a better idea of how it really works. It looks like right now you are trying to do frame relay back to back, which also works, but it depends on how you have your settings. If you want to do frame relay encapsulation back to back, take a look at this link: http://www.cisco.com/warp/public/125/frbacktoback_hybrid.html Guy -Original Message- From: PING To: [EMAIL PROTECTED] Sent: 4/11/2002 9:49 PM Subject: Frame-Relay Problem [7:41250] If I have this simple net: 3660(FR Switch)---3640 I am using NM-4T on both routers.

Re: Frame-Relay Problem [7:41250]
Yes. It works from 3660 to 3800. Doesn't work from NM-4T to NM-4T. /N Chris Camplejohn wrote: Did you put frame-relay intf-type on the frame-interface?

Re: Frame-Relay Problem [7:41250]
The question is that Caslow says on page-110 that if FR switching is on, just enabling the encapsulation will bring up the PVC by using inverse arp. I don't see that happening. /N Engelhard M.

Check the clock rate and cabling on both ends. If the clock rate specified is different than what the module supports, then I believe the line will come up and go back down.
