Abstract
An architecture and method for enhancing a TDM cross-connect to perform packet switching. In particular, a method and architecture that adds to an existing TDM switch at least two packet switching line cards that perform all packet-processing tasks includind filtering, shaping and policing, forwarding and scheduling, while utilizing the TDM cross-connect existing infrastructure.
Claims8
A system for performing combined TDM and packet switching comprising:
- a. a modlified TDM cross connect switch that includes a TDM switching matrix configured lo perform TDM tasks, and
- b. at least two packet switching line cards incorporated in said modified TDM switch and connected to said TDM switching matrix, whereby said incorporation of said at least two packet switching line cards in said modified TDM switch provides the system with combined TDM and packet switching capabilities.
A method for performing packet switching in a TDM cross connect switch, comprising:
- i. providing a modified TDM switch that includes a TDM switching matrix and a plurality of packet switching line cards, each of said packet switching line cards having a first plurality of ports, each said port having a respective rate,
- ii. configuring a plurality of TDM circuits across said TDM switching matrix between each pair of said plurality of packet switching line cards, and
- iii. using said circuits to switch packets through the TDM cross connect switch
A method for emulating the transmission of a TDM signal over a packet network, comprising
- a. providing a modified TDM switcb that includes a TDM switch matrix, at least one TDM line card, and at least one packet switching line card having a plurality of ports, and
- b. packetizing and de-packetizing the TDM signal transmitted over the packet network using said modified TDM switch.
