22 V6100 and V7122 User GuideTP-260 OverviewThe TP-260 SIP PCI VoIP media gateway board is a complete SIP-compliant ‘mediagateway on a board’, delivering cost-effective solution in a convenient PCI form-factor. Thisunique stand-alone PCI media gateway operates independently and relies on the host PCIonly for its power. The TP-260 communicates to applications via SIP using an on-boardEthernet interface. Using a special standards-based approach eliminates host PC devicedrivers and operation system dependencies, seamlessly connecting existing PSTN-basedsystems to support VoIP.The TP-260 is an ideal solution for SIP trunking gateways and integrated media gateways forIP-PBXs and all-in-one communication servers. The board is designed for enterpriseapplications or for smaller to medium PC-based systems. The TP-260 provides up to 240simultaneous ports for voice, fax or data for VoIP media gateway applications providingexcellent voice quality and optimized packet voice streaming over IP networks. EmployingSIP as a control protocol, the TP-260 enables System Integrators short time-to-market andreliable cost-effective deployment of next-generation networks. The TP-260 utilizes the TPM-1100 PMC module, which is based on the VolPerfect™ architecture, 3Com' underlying coremedia gateway technology.The TP-260 matches the density requirements for small to medium locations, while meetingNSP’s demands for scalability. The TP-260 stand-alone VoIP gateway on a board, scalesfrom 1 to 8 E1/T1/J1 spans in a single PCI slot and provides an excellent gateway solutionfor enterprise applications as well as carrier locations.The TP-260 supports various ISDN PRI protocols such as EuroISDN, North American NI2,Lucent™ 4/5ESS, Nortel™ DMS100 and others. In addition, it supports different variants ofCAS protocols for E1 and T1 spans, including MFC R2, E&M immediate start, E&M delaydial / start, loop start and ground start.The TP-260 enables the deployment of ‘Voice over Packet’ solutions in environments whereaccess is enabled to PSTN subscribers by using a trunking media gateway. This providesthe ability to transmit voice and telephony signals between a packet network and a TDMnetwork. Routing of the calls from the PSTN to a SIP service node (e.g., Call Center) isperformed by the TP-260 internal routing feature or by a SIP Proxy.Enabling accelerated design cycles with higher density and reduced costs, the TP-260 is anideal building block for scalable, reliable VoIP solutions. With the TP-260 comprehensivefeature set, customers can quickly design a wide range of solutions for PSTN and VoIPnetworks.
