TRANSip Functions and IMS

IP Multimedia Subsystem (IMS) is a standards-based architecture for delivering IP-based media (voice, video, etc.) with use of the Session Initiation Protocol (SIP). Some of the functions of TRANSip mentioned above can be further broken down into key functions of the IMS architecture. Examples of key IMS functions provided by TRANSip include:

Home Subscriber Server (HSS)

Profile information (name, extension, feature settings, etc.) for IP and Access subscribers on a TRANSip-enabled system is embedded in the system database. TRANSip also supports authorization and authentication of IP users.

Call Session Control Function (CSCF)

TRANSip comes with a powerful call controller that can support thousands of concurrent calls, depending on system configuration. Examples of CSCF functions provided by TRANSip include:

  • Subscriber Authentication
  • Trunk Authentication
  • Registrar
  • TLS encryption
  • QoS Marking
  • Call Detail Record (CDR) generation
  • Call Routing

Media Gateway Control Function (MGCF)

On TRANSip-equipped HDX and SLICE 2100 platforms, TRANSIP offers fully integrated control of the Media Gateway (MGF) without the need for add-on equipment. TRANSip seamlessly merges next-generation VoIP (SIP) networks with legacy PSTN / TDM networks, all in one device.

Wheel-CO.jpgMedia Gateway Function (MGF)

Both the HDX and SLICE 2100 (when equipped with TRANSip) operate as a powerful VoIP gateway. On the VoIP side, many codecs are supported including G.711 A-law, G.711 μ-law, G.723.1H&L, G.726 (16, 24, 32, 40 kb/s), G.729 A&B, iLBC, as well as T.38 for Fax over IP and V.150.1 for Modem over IP. On the TDM and analog side, a wide variety of interfaces are available, including E1, T1, E&M, Ground Start and Loop Start trunks, Magneto, and Radio interfaces with support for many industry standard protocols including ISDN PRI, IDSN BRI, SS7, C7, SS5, DTMF, MF, R2, GR-303 and V5.2.

Breakout Gateway Control Function (BGCF)

TRANSip performs call routing based on telephone number. Outbound calls can be routed via VoIP to another network / system, or via TDM (using the MGCF functionality).

Multimedia Resource Function (MRF)

TRANSip offers extensive conferencing capabilities; this could be used for something as simple as three-way-calling to something as complex as multi-party conferencing with over 100 parties with access control. TRANSip offers customizable PSTN tones for use in many different countries. In addition, TRANSip can support both pre-recorded announcement tokens, and custom recorded announcements.

TRANSip Enhanced Services

Lawful Intercept (HDX and SLICE 2100 only)

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.

Number and Feature Portability

TRANSip’s unified design creates an easy transition to the IP world by allowing subscribers 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 that provides 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.
