You set up the channels once, on the service module. The logical sub-interfaces are set up without channel info. Think of the service-module as the CSU/DSU portion of the interface.

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.
