Filed:

Dec 13, 1994

Appl. No.:

8/356445

Inventors:

Felix V. Diaz - Plano TX
Raymond L. Hogg - Carrollton TX
Daniel J. Raz - Plano TX
Kathy A. Thompson - Garland TX
Gregory L. Langdon - Addison TX
W. Keith Brewer - Richardson TX

Assignee:

DSC Communications Corporation - Plano TX

International Classification:

H04L 1240

US Classification:

370 581

Abstract:

Three data formats for telecommunication networks are provided. One format is an asynchronous packet bus overlay datagram format (122) constructed to include an internal datagram header (140) and a datagram payload (141) concatenated with the internal datagram header. The internal datagram header comprises a destination address (146), a weighted age (152), and a source address (14). A second format is a wideband bus overlay format (126) comprising three header octets and a plurality of payload octets such that the data is formatted into one of a plurality of industry standard isochronous wideband data formats. A third format is a narrow band bus overlay format (124) comprising a plurality of signaling octets, a plurality of octets concatenated with the first plurality of signaling octets to hold data, and a common system multiframe structure.

US Classification:

370 16

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.
