A communication controller is disclosed with a plurality of service modules including a redundant service module and with a mechanism for substituting the redundant service module for any one of the service modules. The communication controller includes a redundancy module that distributes communication signals to the redundant service module via a distribution bus coupled to the service modules. The distribution bus is alternatively used to distribute a high speed communication link to the service modules for improved physical connectivity.
