Based on what I know, when leased line connections are made, a router port is required for each connection along with a CSU/DSU as well as the circuit from the service provider. It is only channelized interfaces that do not require external CSU/DSU because they have this funtionality built in. You must have a channelized E1 that you are not using CSU.
