We're in the process of upgrading a circuit from 256 Mb to a t-1. I've verified that the hardware is fine (though we will be upgrading hw at a later time), but have a question on the config. The only thing I would need to change on the config is serial interface, bandwidth to 1536, correct? The router is 1751, IOS 12.2(11)T10.
Thanks,

the bandwidth command will not change the speed of the interface. Please post the relevant info from your config.

Here's our current serial interface:
interface Serial0/0
description cir: 34.HCGS.416547
bandwidth 256
no ip address
encapsulation frame-relay IETF
no fair-queue
service-module t1 timeslots 1-4
frame-relay lmi-type ansi
!
interface Serial0/0.100 point-to-point
description lexington to host
bandwidth 256
ip address 192.168.0.22 255.255.255.252
no cdp enable
frame-relay interface-dlci 100 IETF
thanks,

Hi Chris,
No, the bandwidth command is used by routing protocols, QoS and other tools, it doesn't control the physical speed of the interface, the CSU/DSU connected to this interface controls the speed, i guess your provider will do this for you.

The only change required to use the full T1 is to enable the service module t1 timeslots all command.
int s0/0
service-module t1 timeslots all

Sundar,
You are totally correct, i've missed that this is a channelized interface, and Chris please make sure that your provider has modified the T.S configuration on the CSU/DSU to match yours.
HTH,
