Abstract
A gateway digital loop carrier device accommodates an integrated access device accommodating as a subscriber at least one of a telephone, a modem and ISDN and implementing a TR-008 interface, executes an interface conversion between TR-008 and TR/GR-303, and connects the subscriber to a switch implementing a TR-303 or GR-303 interface.
Claims5
A gateway digital loop carrier device comprising:
- an integrated access device side terminating unit terminating a transmission signal sent from an integrated access device accommodating as a subscriber at least one of a telephone, a modem and ISDN and implementing a TR-008 interface;
- a demultiplexing unit demultiplexing the terminated transmission signal into DS0 signals;
- a unit performing interface conversion of the demultiplexed DS0 signal from TR-008 to TR-303 or GR-303;
- a TR/GR-303RDT unit based on TR-303 or GR-303 and having a plurality of subscriber ports for sending the interface-converted DS0 signal to a switch implementing a TR-303 or GR-303 interface;
- a trouble detecting unit for detecting a trouble on a transmission path between said integrated access device and said gateway digital loop carrier device;
- and
- a service state information converting unit for converting the detected trouble into subscriber service state information of which said switch is notified,
- wherein said switch is notified of the subscriber service state information.
