Abstract: A network termination card is provided which allows new services to be implemented on the DSLAM on which the network termination card is located without restricting the number of slots used for line termination cards. Software controlled multiplexers are provided on some ports of the switch on the network termination card, and a daughter card connector is provided on the network termination card. When a new service is to be implemented, a specialized daughter card implementing the service can be connected to the daughter card connector. The multiplexers can then be configured to allow the necessary number of ports from the switch to communicate with the daughter card connector, while other multiplexers can be configured to retain communication between the switch and normal components of the DLSAM.

Abstract: A system and method for control management of shared peripheral circuits by a plurality of controllers is provided. Control of the peripherals is mediated through a shared signal controller which uses mask registers to ensure that only one controller may control a peripheral at any one time, and that the type of peripheral is matched to the type of controller.

Abstract: A hybrid IP/ATM NT and method are provided for hybrid IP/ATM network termination. While traversing a DSLAM, ATM traffic over ATM network infrastructure and GigE/IP traffic over GigE/IP network infrastructure may be recast into crossover GigE/IP traffic and crossover ATM traffic respectively, and routed to the opposite kind of network infrastructure with use of the IP/ATM NT and hybrid IP/ATM network termination.

Abstract: An apparatus is described having an ATM switch core, wherein the ATM switch core has an input coupled to an ingress AAL2 switch engine and an output coupled to an egress AAL2 switch engine. The ingress AAL2 switch engine has a first look-up table that can store: 1) an identification label for an AAL2 virtual channel through said ATM switch core; and, 2) an AAL2 egress connection identification label for an ingress AAL2 packet to be carried by the AAL2 virtual channel. The egress AAL2 switch engine has a second look-up table that can store an egress CID and egress VPI/VCI for the AAL2 egress connection identification label.
