Abstract:

A serial channel switch circuit and modular packet switch using the serial channel switch circuits are disclosed. The serial channel switch circuit has a reconfigurable table for internal logical-to-physical channel switch translation. Depending on the slot in which a card containing such a serial channel switch circuit is inserted in the modular packet switch, its serial channel switch circuit may receive a different set of reconfigurable table values that are specific to that location. A global set of logical channel values can be applied to each card, which performs logical-to-physical channel mapping according to its location in the modular packet switch. Other embodiments are also described and claimed.
