Connecting the VoIP and PSTN worlds

Compact, High Performance and cost effective SS7 to IP Gateway. Signalling & Media Gateway in one box

Ideal for ISPs, pure-play VoIP operators or for adding VoIP connectivity to legacy switches

SS7 interfaces are increasingly being used to connect to PSTN networks in situations where Q931 / ISDN PRI was used before. Whilst this gives operators a more powerful interface with higher level performance and reliability it can also mean expensive, heavily engineered signalling gateways are required.

Itgives you an easy to use, cost effective way of connecting VoIP based traffic to SS7 networks.

1 to 16 Signalling Link Pairs 1 to 32 E1 trunks SIP and H323 30 to 960 VoIP calls MTP Layer: ITU Q704, ISUP Layer: ETSI

Based on the field proven signalling software installed on more than 100 operators. Support for many country / carrier variants.

OSST – Optimised SS7 Transport

WTL have developed the highly efficient OSST to allow SS7 signalling to be carried through IP networks. This protocol encodes the full range of SS7 messages in a secure, compact way which has been optimised for IP transport. OSST then uses smart routing algorithms to decide which device in the network to send the SS7 message to. SS7 call control can thus be extended to remote SS7 trunks anywhere in the network or converted to be compatible with VoIP protocols.

Carrier Grade Reliability

It has the SS7 support of a full blown Class 4 switch in a simple gateway format Full remote management Web based user interface Robust Solaris operating system Distributed MTP3 (DMTP3) allows redundant network design 1 to 16 SS7 signalling link pairs (upgradeable by software key) SS7 & VoIP trace facilities Compatible with wide range of IP equipment Scalability – SoIP starts with capacity for 30 simultaneous calls. Upgradeable to 960 calls and stackable to 61440 calls (2048 E1s). A private Ethernet port provides a html web browser interface with password protected access levels to allow configuration, administration, traffic monitoring and diagnosis.

Protect Your Investment in Existing Networks

Our goal is to give service and equipment providers the core technology needed for network convergence. Providers have made huge investments in services deployed on their legacy networks, and they have to be able to share services across legacy networks and with IP-based networks. SS7 Signalling Gateway allows multiple traffic types to co-exist in the same network.
