What is TRANSip®?

TRANSip is REDCOM's IP telephony technology suite. TRANSip is a truly integrated VoIP solution that incorporates the maximum benefits of TDM and IP technologies. This gives greater total benefit than the simple sum of the two components.

Available in the REDCOM HDX and SLICE 2100® platforms, TRANSip technology provides SIP Call Manager, Media Gateway, Media Gateway Controller, and a full range of related IP telephony capabilities and features. TRANSip offers a simple, fully integrated VoIP solution that is easy to configure and install.

TRANSip technology also supports traditional TDM transport and signaling interfaces and features. Using REDCOM's TRANSip-enabled HDX or SLICE 2100 you can support the following within a single system:

  1. IP telephony to IP telephony connections
  2. IP telephony to TDM connections
  3. TDM to IP telephony connections
  4. TDM to TDM connections

TRANSip® incorporates a full TDM feature set, coupling REDCOM’s world renowned reliability and extensive telephony experience to create a fully integrated solution. TRANSip allows you to benefit from VoIP features while leveraging your existing network elements.

TRANSip works today, respects the past, and anticipates your telephony needs in the future.

TRANSip Core Elements and Services

TRANSip Core Elements & Services

TRANSip Core Elements

Call Manager

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

Media Gateway / Media Gateway Controller

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 (G.711 to 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 Gateway operations with call control signaling. Real Time Transport Protocol (RTP) and Session Description Protocol (SDP) are all supported by this core element.

Legacy Support

REDCOM 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 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® relieves the headaches of extending legacy call monitoring capability to IP subscribers. Its integrated design provides lawful intercept, third party monitoring, recording, and tracing for both IP and legacy subscribers (using CALEA in the USA) within the same platform.

Number and Feature Portability

TRANSip's unified design creates an easy transition to the IP world by allowing customers to retain or transfer their numbers and features. IP subscribers can still benefit from standardized tones, announcements and other legacy features currently available to residential and business customers.

Billing

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

Flexible Routing

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.
