SS7 to IP Signaling Gateway for Legacy Network Interworking

Service Providers are making the transition to 4G but legacy connectivity for voice, SMS and IN applications still remains an absolute requirement. SS7 TDM interfaces must be maintained to meet the demand to interconnect different networks and multi-protocol solutions are required to connect divergent circuit and packet switching architectures. SS7 isn’t retrograde – it’s traditional. It’s still the most robust, high performance, and reliable signaling solution out there and it’s needed today more than ever.

The Adax Gateway (AdaxGW) meets any signaling interworking requirement delivering the scalability, flexibility, throughput, and performance that enables Service Providers to manage the convergence and growth of their networks whilst maintaining legacy connections and infrastructure. It is also the ideal Signaling Gateway replacement for the End of Life Cisco ITP.

Adax Gateway Features and Benefits

  • Maintains SS7 TDM connectivity, IP-enables any legacy node and interworks with cost effective IP links, avoiding expensive STP replacement
  • Ideal replacement for Cisco ITP
  • Interfaces and Protocols supported for all legacy interworking requirements:

TDM Connectivity:
– T1/E1/J1 LSLs, Annex A HSLs, ATM T1/E1, OC3, OC12, GbE

Protocol Interworking and Conversion:
– ANSI, ITU, ETSI, UK, Chinese and Japanese national variants
– SIGTRAN M2UA, M2PA, M3UA and SUA
– SS7 GTT, SCCP, MTP3/b, MTP2/Annex A and ATM

Signaling Interworking:
– SS7/IP, IP/IP or ATM-IP

  • Unparalleled scalability and flexibility to protect investment in both Legacy and IP networks:
    − Delivers the link density and throughput to enable Service Providers to manage the convergence and growth of their networks
    − Enables Service Providers to maximize revenues and satisfy consumer demands for new services whilst maintaining both traditional TDM signaling and new IP networks
  • High-Availability options with no loss of service during switchover
  • One management interface for all configurations that are reconfigurable & re-deployable
  • Pre-integrated RMS or ATCA boxed solution
  • Software can be integrated in to user’s RMS platform or virtualized Linux environment
  • Telcordia certified at Release 3.4 and designed to meet NEBS-3
