Abstract:
A broadband system for connecting a call having a time division multiplex format, the system comprising:a SONET ring adapted to interconnect devices coupled to the SONET ring, the SONET ring comprising a plurality of SONET multiplexers coupled by a SONET path, wherein the SONET multiplexers are adapted to add the-call to, and drop the call from, the SONET ring; an ATM cross connect system comprising a plurality of ATM cross connect devices coupled to the SONET multiplexers, the ATM cross connect devices adapted to provide a provisioned ATM connection through the SONET multiplexers over the SONET path; a plurality of ATM interworking units coupled to the ATM cross connect devices, the ATM interworking units adapted to interwork the call with the provisioned ATM connection in response to control messages, wherein the provisioned ATM connection is provisioned by the ATM cross connect devices between the ATM interworking units through the SONET multiplexers over the SONET ring; and a signaling processor system adapted to receive call signaling for the call, to process the call signaling to select the provisioned ATM connection for the call, and to send the control messages to the ATM interworking units designating the provisioned ATM connection.
