Abstract:
A method for managing bandwidth operative in a digital loop carrier system, the system comprising a central digital terminal and a remote digital terminal, wherein each digital terminal includes a transport card hang a given bandwidth capacity, wherein the remote digital terminal further includes a plurality of service cards connected to the transport card of the remote digital terminal, each of the service cards supporting at least a plurality of channels, the method comprising the steps of:upon initiation of a fist call, allocating the rest call to a given time slot of the transport cards of the central and remote digital terminals; assigning the given time slot a given default bandwidth for each transport card; while the first call is in progress, determining whether the first call is voice or data; and if the first call is voice, selectively reducing the given default bandwidth allocated to the first call on each transport card, if necessary, to ensure that a second call, initiated while the first call remains in progress, can be assigned the given default bandwidth.
