Abstract
Abstract A switch, which connects ports on a customer port module to ports on a network port module via time slots on a dime division multiplexing bus, determines for each connection a number of required time slots, based on the current switch configuration and/or the signal traffic at the associated port. The switch then determines if it has the required number of time slots available generally and if it can make the time slots available to the port. If so, the switch assigns the time slots to the port and completes the connection. The switch determines the number of time slots required by consulting a stored port type indicator table, which lists bandwidth demand based on port type, or by detecting in-band signaling information that indicates the bandwidth demand. If the table indicates that the switch includes non-blocking ports, the switch coordinates the number of time slots allocated to a connection with the number of slots required to be kept free for the non-blocking ports. The switch may thereafter dynamically allocate time slots to the connection, based on signal traffic. The switch may be reconfigured at the request of a customer, by updating routing and port type information stored in the switch. Also, control circuitry in the switch may initiate a reconfiguration, based on signal traffic.

Claim 36
Dependent Claim
135 words
The method of connecting signals from a customer port on a customer port module to a network port on a network port module of claim 22, wherein the step of determining if time slots are available further includes the steps of: v. comparing a number of time slots required to be kept free for the non-blocking ports with a number of available time slots; vi. determining if the number of time slots available exceeds the number of time slots required to be kept free by a number of time slots that is equal to or exceeds the number of time slots required by the requesting customer port; vii. if so, assigning the required number of time slots to the requesting port and viii. if not, refraining from assigning the time slots to the requesting port.
