GIII gateway


Aculab’s GIII gateway is a versatile problem solver of
compatibility issues in any telecommunications network and
is the flagship successor to Aculab's GroomerII gateway.

Beneficially, the GIII gateway protects legacy investments, offering TDM-to-IP interworking and TDM-to-TDM protocol conversion with many essential call routing features.

The GIII gateway is optimised for SIP (SIP 2.0 – RFC 3261 ) and SS7 interworking, with signalling protocol conversion and media gateway functionality in line with industry standards.

Aculab’s GIII gateway offers all of the features and benefits that made its predecessor "the gateway of choice" for the protocol interworking function (PIF) of legacy network gateways for public safety and emergency services communications, and more, in a fourth generation platform evolution.

  • Versatile, simple to use
    Deployment ready solution

    The GIII gateway is the “gateway of choice” for SS7 and SIP interworking in NG9-1-1 / 112 applications

  • Essential call routing features
    NEBS compliant chassis

    Offered in a carrier grade, 2U chassis for any telco deployment where SS7 and SIP interworking is needed

  • Wide range of protocols supported
    Wide range of protocols supported

    Including legacy CAS, MF-CAMA, ISDN PRI, SS7 and SIP 2.0

Technical specifications

Detailed information on feature sets, protocol support and applications.

    • Multi-protocol signalling and media gateway – for any carrier/telco, service provider or telecommunications equipment manufacturer needing TDM-to-IP and/or IP-to-TDM conversion and interworking
    • Interoperability and call routing – between disparate networks
    • Optimised for SS7-to-SIP 2.0 interworking and call routing – with no hidden costs or additional licensing fees for SS7 signalling links
    • Emergency services “media gateway of choice” – for next generation 1-1-2 and 9-1-1 protocol interface function (PIF) in EENA/NENA i3 defined legacy network gateways - NEBS compliant 2U chassis
    • Multiple, deployment proven signalling protocol stacks – including legacy CAS, MF-CAMA, ISDN PRI, SS7 and SIP 2.0; the GIII gateway can be deployed in practically any telecommunications network worldwide
    • Cost-effectively extends life of legacy equipment – enables the extension of hosted, IP-based, added value services towards users/subscribers in legacy PSTN/PLMN networks
    • Redundancy – multiple GIII gateways can be configured to operate in a dual redundant SS7 signalling architecture for added reliability in high availability environments
    • Supports many call routing options – including number translation, and enables users to benefit from configurable call balancing and essential failover options in critical SIP 2.0 deployments
    • Protocols supported include – legacy CAS, MF-CAMA, global ISDN PRI, and international SS7 ISUP via E1/T1 trunks; and SIP 2.0 via redundant Ethernet
    • Supports multiple, single and redundant SS7 A-links or F-links – with configurable options for ANSI, ITU-T, UK ISUP, and China ISUP call control signalling
    • Protocol conversion channel count – supports multiple, simultaneous protocol conversions with no reduction in channel count, regardless of CODEC (vocoder) scheme in use (G.711; G.729AB; G.726)
    • Channel counts – up to 960 simultaneous TDM to IP or IP to TDM protocol conversions in a single chassis
    • Format – 2U, 19” rack mountable, server-based chassis, with dual, hot swap PSUs and RAID Level 1
    • Easy administration – log in to a web-based UI at a single gateway to control all GIII gateway nodes in a multi-node, clustered system
    • Management features – benefits from remote ‘lights out’ and SNMP V3 capability, providing a standard GIII MIB and all appropriate traps and alarms to users’ existing central network management facilities via Ethernet
    • Encryption – shipped as standard in a 'restricted availability' version, subject to international export restrictions, with support for SIPs and SRTP
    • Environmental – The GIII gateway is fully RoHS and WEEE compliant and for carrier/telco deployments in the USA, models with CLEI coding and OSMINE TIRKS compatibility are available
    • Deployment proven signalling and media gateway
    • Interworking between disparate network types
    • Call routing, based on e.g., numbering plans; number translation; fallback routing; and failover scenarios
    • Handle large media gateway traffic volumes in TDM-to-IP or IP-to-TDM conversions
    • Interconnection between SS7 and SIP in next generation 1-1-2 and 9-1-1 EENA/NENA i3 architectures
    • Add IP connectivity to an existing PBX/ACD system or connect an IP-PBX to an SS7, ISDN PRI or legacy CAS network
    • TDM-to-TDM protocol conversion

What our customers say…

  • BT
  • PayTel
  • When we needed a totally reliable and mission critical connection device that gave us good visibility of any problems, Aculab’s GroomerII was the natural choice.

    Andy Dennis, BT

  • Aculab was very quick to understand our requirements and make the changes we need to get our development efforts underway. The ongoing support and consultation from Aculab was a tremendous asset.
