PCT No. PCT/CA94/00377 Sec. 371 Date Mar. 11, 1996 Sec. 102(e) Date Mar. 11, 1996 PCT Filed Jul. 13, 1994 PCT Pub. No. WO95/02951 PCT Pub. Date Jan. 26, 1995A time division switching matrix capable of effecting rate conversion comprises a plurality of serial inputs for connection to respective serial input links, each capable of carrying time division multiplexed PCM channels, a plurality of serial outputs for connection to respective serial output links, each capable of carrying time division multiplexed PCM channels, and a serial-to-parallel converter associated with each input for converting a serial input stream to parallel format, each said serial-to-parallel converter being independently configurable to produce the same net parallel throughput regardless of the bit rate of the associated input link. The serial-to-parallel converters are staggered length shift registers. The output side of the switching matrix can be similarly configured.
