Signaling System 7

NewNet is a reliable resource for carriers and others using the SS7 (Signaling System 7) stack for telecommunication services and system testing. NewNet’s range of SS7 products include:

Distributed 7

Distributed 7 is designed for telecommunication equipment vendors in wireless, VoIP, and wireline networks.  The Distributed7 platform can perform as an SS7 link concentrator, functioning as a Signaling Transfer Point (STP). In this configuration Distributed 7 receives traffic from the SS7 network and routes it to specified Signaling End Points (SEP).

When deployed as a mini-STP, Distributed7 lowers the costs of operation within service provider’s networks by reducing the number of expensive links needed on Class 5 switches. Additional cost reduction is achieved by consolidating the number of links connecting to an inter-working network. Service providers can benefit when using Distributed7 as an interconnecting node and as an internal hub for SS7 traffic.

Benefits include:

  • SS7 Link Replacement – Distributed 7 can be used to replace underutilized, expensive long-haul SS7 links
  • Enhanced Services – Can act as an interface between application/service databases developed for either the PSTN or IP networks enabling use of new applications on legacy networks
  • Mobile Roaming – Where traffic doesn’t justify the cost of a dedicated SS7 link, roaming services can be offered by utilizing the SC1510
  • VoIP – Enables services to transparently function between the PSTN and packet data networks, allowing calls to be completed between legacy and IP networks
  • Standards-based SIGTRAN and SS7 protocols including integrated GTT services support to and from IP

Connect 7

Connect7 adds high availability SS7 support to Distributed 7’s core with innovative redundancy.  Connect 7 supports distributed system functionality in the MTP, SCCP, TCAP, and ISUP layers. In the distributed configuration, two computing hosts can be configured to run concurrently, as part of a single signaling point to ensure reliability.

Links from the SS7 network terminate on multiple hosts, even if they belong to the same link set. Furthermore, all hosts are simultaneously active. If a host becomes inoperative, the other host continues to pre-serve the active ISUP calls, bringing availability to 99.999%

Key Benefits Include:

  • Reliable – Dual host distributed and concurrent signaling for reliability
  • Cost Efficient –  Operates on industry-standard, NEBS-compliant servers
  • Open, Standards-based – Supports SIGTRAN and SS7 protocols
  • Scalable– Link density of up to 16 SS7 links (16 links per Server or per Cluster)
  • Globally Optimized– Compatible with networks in over 60 countries Including ANSI, ITU, China, and country variants of MTP, ISUP, SCCP and TCAPGSMA I/F, GSMMAP, ANSI 41
  • Virtual SS7 Environment simulating an SS7 board, its driver, and cable connections
  • SS7 Interface Support for T1, El, and J1(75, 100,120 Ohm), V.35 and RS-449 interlaces
  • Node management with MML, GUI, and SNMP

Sigtran Gateway

The Sigtran Gateway allows solution providers to protect their investment in existing SS7-based applications while benefiting from the migration to cost-effective IP backhaul by allowing SS7 signals to be transported over IP Networks.

Features Include:

  • Runs on Off-the-shelf Unix Platforms
  • ANSI 1992, 1996 and ITU 1993, 1997 SS7 compliance
  • Distributed architecture
  • Support of industry standard SIGTRAN Protocols including RFC 3332 compliant M3UA and RFC 2960 compliant SCTP.
  • STP routing capabilities
  • Provisioning through MML and GUI
  • Routing key support for DPC, OPC, SIO and CIC ranges
  • GTT Support
  • IETF LAN security specification support for SCTP
  • SNMP support
  • Support of country specific variants (China, etc.)
  • ASP/network simulator

Sigtran Gateway Client

The Signaling Gateway Client is an application development node that integrates SS7 and SIGTRAN services. It provides seamless connectivity to both the public switch telephone network (PSTN) and IP networks.

Key Features Include:

  • SIGTRAN Stack compliant with RFC 3332/4666, M3UA, and RFC 2960 complaint SCTP
  • SS7 Stack – ANSI (1992, 1996), ITU (1993,1997) complaint, SCCP, TCAP, ISUP
  • System Administration and Network Configuration Interface – Standards-based MML and SNMP
  • SS7 API – C/C++ API for SCCP, TCAP, and ISUP, JAIN API for TCAP/ISUP
  • Systems Availability – 99.999% availability in distributed configuration
  • IP to SS7 routing mechanisms Routing keys based on DPC, OPC, SIO, and CIC
  • Secured with IPSEC
