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. The invention allows flexibility in which and how many ports of the switch are used to communicate with the daughter card, thereby allowing a new service to be implemented via the DLSAM without limiting communication between the switch and other regular components beyond what is necessary.
1. A network termination card comprising:
a daughter card connector;
a switch; and
a plurality of software-controlled multiplexers, one on each of a plurality of ports of the switch, a first connection of each multiplexer leading to the daughter card connector and a second connection of each multiplexer leading to another component corresponding to the port on which the multiplexer is located, wherein the configuration of each multiplexer can be individually controlled to allow communication either between the switch and the daughter card connector or between the switch and the corresponding other component so as to change the number of ports which communicate with only the daughter card connector.
