Using traffic shaping, you can prevent the hub from trying to send data down a PVC at greater than 256 kbps - without traffic shaping, the router doesn't know that the other end can only deal with 256 kbps, but the telco's switch does and will drop any traffic above 256kbps. A presentation at Networkers 2000 Melbourne had some good guidelines for frame relay traffic shaping - I don't know a URL (or even if it's online still), but drop me a note if you're interested.

And yes, the host has 768 kbps bandwidth, and each of the three branch offices has 256 kbps. All I needed to know was if I needed any timeslot config on the subs, but I now know that I don't.

Only Ole can clarify what he meant. My point ( and yours ) is that there is no way or need to do further configuration on the host site with regards to the frame connection. The timeslots are not "reserved" in terms of which DLCI uses which timeslots or group of timeslots. all data will go out the physical interface as fast as the wire permits. the layer three to layer two mapping will determine which PVC gets which of those frames.

Is this true? If that's the case, unfortunately there is no way to do this on the router. When you order a FR circuit, you are typically ordering a T1 for layer 1 so you really are just getting 1 "pipe" capable of flowing 768k. The DLCIs converge into this pipe in a logical fashion, not a physical one, hence the layer 2 stuff (FR encapsulation) needed at this point. --- Rik Guyler -----Original Message----- From: Chuck Larrieu [mailto:[EMAIL PROTECTED]] Sent: Friday, September 07, 2001 11:21 PM To: [EMAIL PROTECTED] Subject: RE: FR question - Configuring Fractional T1 on the WIC-1DSU-T1 [7:19081] Ole, my man, you are trying to outsmart yourself, and you're a pretty smart guy ;-> Your T1 module is for the telco interface only. You purchased 768K, it appears. Your DLCI's / PVC's will share that 768K with no further layer 1 actions on your part once you have properly configured the layer one stuff - the timeslots and B8ZS and ESF and yellow alarm and loopback and clock source, you are done with the service module. All that remains is assigning the DLCI's to the appropriate subinterface, and IP addressing for the PVC's, and you are on your way.

I have a Frame Relay scenario being setup, and my host router has just received the green light from the provider. The Frame Relay host uses 12 channels, and connects on three PVC's to three branch offices, each with 4 channels. I searched and found the answer on how to setup the channels on cisco's site: router(config-if)#service-module t1 timeslots 1-12 but will I have to do that for my three sub interfaces also? Example: router(config)#int s0/0 router(config-if)#service-module t1 timeslots 1-12 router(config-if)#int s0/0.101 point-to-point router(config-subif)#frame-relay interface-dlci 101 router(config-subif)#service-module t1 timeslots 1-4 router(config-subif)#int s0/0.102 point-to-point router(config-subif)#frame-relay interface-dlci 102 router(config-subif)#service-module t1 timeslots 5-8 router(config-subif)#int s0/0.103 point-to-point router(config-subif)#frame-relay interface-dlci 103 router(config-subif)#service-module t1 timeslots 9-12 Thanks and have a great weekend, Ole ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Ole Drews Jensen Systems Network Manager CCNA, MCSE, MCP+I RWR Enterprises, Inc.
