ABSTRACT:
A time slot interchanger (TSI) for a telecommunications node includes an exchange memory and a controller. The exchange memory includes a plurality of exchange memory slots. Each exchange memory slot is sized to store a traffic channel and includes a plurality of discretely addressable fields sized to store a sub-channel. The controller is operable in response to predefined switching instructions to write a sub-channel received in a first traffic channel to a first field in a memory slot and to write a sub-channel received in a second traffic channel to a second field in the memory slot.
