Abstract
A method of switching a plurality of tributaries disposed among a plurality of time slots in a frame is disclosed. The method generally includes the steps of (A) buffering the frame, (B) switching the tributaries among the time slots in response to a read address and (C) generating the read address in response to a plurality of identifications in a connection map, the connection map defining (i) at most one of the identifications for each of the tributaries and (ii) one of the identifications for each of the time slots carrying other than the tributaries.
Claims20
A method of switching a plurality of tributaries disposed among a plurality of time slots in a frame, comprising the steps of:
- (A) buffering said frame;
- (B) switching said tributaries among said time slots in response to a read address;
- and
- (C) generating said read address in response to a plurality of identifications in a connection map, said connection map defining (i) at most one of said identifications for each of said tributaries and (ii) one of said identifications for each of said time slots carrying other than said tributaries.
A system comprising:
- a switch circuit configured to (i) buffer a particular frame comprising a plurality of time slots carrying a plurality of tributaries and (ii) switch said tributaries among said time slots in response a read signal;
- and
- a memory circuit configured to generate said read signal in response to a plurality of identifications in a connection map stored therein, said connection map defining (i) at most one of said identifications for each of said tributaries and (ii) one of said identifications for each of said time slots carrying other than said tributaries.
A system comprising:
- means for buffering a plurality of tributaries disposed among a plurality of time slots in a frame;
- means for switching said tributaries among said time slots in response to a read address;
- and
- means for generating said read address in response to a plurality of identifications in a connection map, said connection map defining (i) at most one of said identifications for each of said tributaries and (ii) one of said identifications for each of said time slots carrying other than said tributaries.
