Multi-service switch for a telecommunications network
First Claim
1. An interface card for providing access to a premises network, comprising:
- an outside communication interface operable to transmit telecommunications information to and receive telecommunications information from an entity outside the premises network;
a premises communication interface operable to transmit telecommunications information to and receive telecommunications information from a system bus interconnecting a plurality of entities on the premises network; and
an interface module control coupled to the outside communication interface and to the premises communication interface, the interface module control operable to perform distributed switching to communicate telecommunications information on the system bus, wherein the interface module control is further operable to receive telecommunications information from the outside communication interface in a first format, to interwork between the first format of the telecommunications information and a plurality of bus overlay data formats, and to provide the telecommunications information in one of the plurality of bus overlay data formats to the premises communication interface for transmission on the system bus, wherein the first format of the telecommunications information comprises an asynchronous transfer mode cell, the interface module control having shared access to the system bus with other interface module controls.

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 (281 through 28n) each have an input and an output. The input of each interface module (281 through 28n) 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).
