With what other systems and networks can the Integral Access PurePacket system interwork?
The PurePacket system can interwork with a wide range of customer premises and core network equipment such as • analog POTS, ISDN, • T1/E1, • SONET/SDH, and • ATM. Voice switch interfaces are terminated using standard TR-08, GR-303 and V5.2 protocols which are supported by the major circuit-switched voice network suppliers such as Lucent, Nortel, Siemens, Alcatel and Ericsson. The system also operates as a Voice Access Gateway operating under ‘SoftSwitch’ control, passing voice traffic to the IP Backbone. A flexible interworking function within the PurePacket system allows the access network to communicate with standard routers and frame relay switches using MPLS and other protocols such as those supported by Cisco, Juniper and Lucent.
