TRANSip Core Elements

TRANSip Core Elements

TRANSip integrates IP and legacy call management functionality while offering call setup, control, termination, and directory services for IP subscribers through Session Initiation Protocol (SIP). TRANSip extends the benefits of legacy features to IP subscribers.

TRANSip's unified design supports media and protocol conversion, creating a seamless interface between TDM and IP technologies. The Media Gateway maximizes use of network elements by performing conversions between VoIP, BRI, GR-303, V5.2, PRI, MF, R2, SS7 and C7.

The Media Gateway supports various codecs and compression algorithms (including G.711 and G.729) to minimize network bandwidth utilization and supports Fax over IP (T.38) and Modem over IP (V.150.1) for compatibility with existing networks.

The Media Gateway Controller operates as an intermediary between the Call Manager and the Media Gateway to synchronize Media Gate-way operations with call control signaling. Real Time Transport Protocol (RTP) and Session Description Protocol (SDP) are all supported by this core element.

TRANSip equipped systems offer legacy features that maintain and expand existing network services offering line access methods like GR-303 and V5.2, and supporting analog interfaces with up to 1900 ohm loop lengths.

To ensure compatibility with existing networks, T1, E1, analog E&M and ringdown trunks are also supported. TRANSip maintains modem, fax, CLASSSM, call forwarding, Caller ID and many other legacy features to further enhance compatibility.

TRANSip Enhanced Services

Lawful Intercept

TRANSip provides call monitoring capability (US J-STD-025-B) for IP subscribers. Its integrated design provides lawful intercept, third party monitoring, recording, and tracing for both IP and legacy subscribers (CALEA compliant in the USA) within the same platform.

TRANSip collects and processes IP and legacy call detail records to support accurate account and billing management. Integrity of data col-lection (for all subscribers) is achieved through a powerful integrated control that provides a single interface and format for both TDM & IP usage.

TRANSip incorporates flexible IP and PSTN trunking schemes (including alternate routing and emergency rerouting) that maximize network efficiency, meeting Quality of Service criteria and ensuring successful call completion.
