Abstract
A subscriber network system is provided which is capable of reducing the response time and reducing the device cost. In the subscriber network system, a control cell is received that includes an ID portion, a data portion, and a cyclic redundancy check (CRC) portion. The control cell is processed in cooperation with a virtual path identifier (VPI), where the processing obtains the ID portion and the CRC portion. The ID portion and the CRC portion are processed and the ID portion is compared to a first stored value and the CRC portion is compared to a second stored value to produce information. A cell is produced to include the information and the produced cell is used to facilitate a connection in a network.
Claims20
A method comprising:
- receiving a controlling cell that includes an identification (ID) portion, a data portion, and a cyclic redundancy check (CRC) portion;
- processing the controlling cell in cooperation with a virtual path identifier (VPI),
- the processing obtaining the ID portion and the CRC portion;
- processing the ID portion and the CRC portion;
- comparing the ID portion to a first stored value and the CRC portion to a second stored value to produce information;
- producing a cell that includes the produced information;
- and
- using the produced cell to provide a connection in a network.
A system comprising:
- a processor to:
- receive a controlling cell that includes an identification (ID) portion, a data portion, and a cyclic redundancy check (CRC) portion;
- process the controlling cell, in connection with a virtual path identifier (VPI), to obtain the ID portion and the CRC portion;
- process the ID portion and the CRC portion;
- compare the ID portion to a first stored value and the CRC portion to a second stored value to produce information;
- produce a cell that includes the produced information;
- and
- use the produced cell to provide a connection in a network.
A method comprising:
- controlling a call between an exchange and a destination;
- receiving information associated with the call;
- generating a control cell to carry change information, associated with a cell filter of a plurality of cell filters, based on the received information;
- and
- making the control cell available to the destination,
- the control cell being associated with establishing the call.
