Abstract
A multi-service switch for a telecommunications network (10) is provided. A system bus (13) has an ingress portion (14) and an egress portion (16). The system bus (13) is operable to carry data in a plurality of time slots. A system bus control (11) comprises a head-of-bus control (12) having an output. The output of the head-of-bus control is coupled to the ingress portion (14) of the system bus (13). The system bus control (11) also comprises a tail-of-bus control (15) coupled to the head-of-bus control (12). The tail-of-bus control (15) has an input coupled to the egress portion (16) of the system bus (13). A plurality of interface modules (28.sub.1 through 28.sub.n) each have an input and an output. The input of each interface module (28.sub.1 through 28.sub.n) is coupled to the egress portion (16) of the system bus (13), and the output of each interface module is coupled to the ingress portion (14) of the system bus (13). An ingress/egress bridge (18) has an input and an output. The input of the ingress/egress bridge (18) is coupled to the ingress portion (14) of the system bus (13), and the output of the ingress/egress bridge (18) is coupled to the egress portion (16) of the system bus (13).
