Abstract
Multi-service telecommunication switches which include enhanced component redundancy and which also allow multiple chassis connections to a switching fabric enhance the likelihood that packets transmitted to and from the switch will not be lost due do a particular component failure and also enable chassis stacking in a rack system. Such a multi-service telecommunication switch includes redundant physical layer adapter cards, redundant service cards, redundant timing modules, and redundant switching fabrics. Further, the multi-service telecommunication switch, includes an enhanced data flow distribution (load-balancing) architecture which enables multiple chassis connections to the switching fabrics.
