Abstract
A telecommunications system has identical access terminal shelves and an intershelf bus interconnecting each shelf. Each access terminal shelf has transmission card slots constructed to accept different types of transmission cards that use different types of transmission media to communicate with remote telecommunications equipment and a processor programmed to determine whether transmissions from the remote telecommunications equipment are to be transferred to the intershelf bus for connection completion.
Claims17
A method of managing telecommunications traffic in a telecommunications access terminal having a first shelf, a second shelf, and an intershelf bus connecting the shelves, the method comprising:
- receiving a transmission from external telecommunications equipment on the first shelf;
- determining, on the first shelf, that a destination of the received transmission is not on the first shelf;
- transferring the received transmission to the intershelf bus;
- and
- processing the received transmission on the second shelf to complete a connection of the received transmission to the destination.
A telecommunications system including a number of shelves comprising:
- means for communicating with remote telecommunications equipment;
- means for accepting a transmission from the remote telecommunications equipment;
- means for determining, located on each shelf, whether completion of a connection of an accepted transmission can be made on a shelf that accepted the transmission;
- means for transferring the accepted transmission to a different shelf;
- and
- means for completing the connection of the accepted transmission,
- wherein the completing means is located on the different shelf.
Software, stored on a computer-readable medium, for a telecommunications access terminal having a plurality of shelves, the software comprising instructions for causing one or more computers to perform the following operations:
- receive a transmission from external telecommunications equipment;
- determine, on a shelf receiving the transmission, if a destination of the transmission is on the shelf receiving the transmission;
- and
- transfer the transmission from a shelf processor of the shelf receiving the transmission to a shelf processor of a shelf including the destination of the received transmission, wherein the second shelf s processor completes the transmission.
A telecommunications system communicating with external telecommunications equipment comprising:
- a plurality of access terminal shelves for receiving the transmission from an external telecommunications equipment;
- a processor, located on each access terminal shelf, programmed to complete a connection for a received transmission having a destination on its shelf, to hand-off a received transmission having a destination on another shelf, and to complete a transmission, handed-off from one of the access terminal shelves and having a destination on its shelf;
- and
- an intershelf bus connected to the access terminal shelves for transferring a received transmission handed-off from one of the access shelves to a different access shelf.
A telecommunications system communicating with external telecommunications equipment comprising:
- a plurality of access terminal shelves for receiving the transmission from an external telecommunications equipment;
- a processor, located on each access terminal shelf, programmed to complete a connection for a received transmission having a destination on its shelf, to hand-off a received transmission having a destination on another shelf, and to complete a transmission, handed-off from one of the access terminal shelves and having a destination on its shelf;
- an intershelf bus connected to the access terminal shelves for transferring a received transmission handed-off from one of the access shelves to a different access shelf, and
- a switching matrix located on each shelf, wherein the processor and the switching matrix perform switching for the received transmission having a destination on the processor's shelf.
A method of handling a transmission in a telecommunications terminal having a first access shelf including a first shelf port and a first shelf processor and a second access shelf including a second shelf port, and a second shelf processor, the method comprising:
- detecting a transmission received at the first shelf port by the first shelf processor;
- determining, by the first shelf processor, that a destination of the received transmission is on another shelf;
- handing-off the received transmission from the first shelf processor;
- accepting the handed-off received transmission by the second shelf processor;
- and
- completing, by the second shelf processor, the connection of the received transmission from the first shelf port to the second shelf port.
