You need to config the CSU/DSU or service-mod to utilize the correct number of channels on the port, regardless of CIR. ELMI or traffic-shaping is used to shape CIR speed.
SO if you orderd a full T1, but only had a 64K circuit (I hope you are using the other channels for voice or something) you would need to configure the CSU/DSU or service-mod to use all 24 channels. -- RFC 1149 Compliant.
