Leading Indian triple play provider Sify Technologies Corporation chooses Squire Technologies’ SVI MGC to replace Cisco PGW and enhance voice services to customers in more than 200 metro areas.

Squire Technologies, signalling specialists to the telecoms industry, today announced that Sify Technologies Corporation, the leading provider of triple play residential and business broadband services in India, has chosen its SVI MGC solution to replace a legacy Cisco PGW softswitch and to provide interconnection and routing between NGN IP and PSTN networks.

Sify, which delivers broadband, voice and media services to more than 200 cities and metro areas across India, was faced with the challenge of replacing its legacy PGW 2200 Media Gateway Controller solution that had been declared “end of life” (EoL) by Cisco. In order to provide seamless service continuity to its customers, Sify needed to deploy a proven solution that offered future-proof capabilities to meet service expansion demands and replace the EoL solution.

“Voice remains a hugely important part of our innovative triple play bundles,” commented Birendra Singh, Head- Voice Technology Operations at Sify. “We see outstanding growth in both domestic and international traffic, so needed a solution that would both meet current and future needs. Squire Technologies was able to replace our existing Cisco solution and provide us with the interconnection we need to service our customers.”

The SVI MGC solution that has been deployed currently supports more than 10,000 concurrent calls in a fully redundant architecture, providing the quality of service and call continuity needed to support Sify’s growing customer base.

Importantly, the SVI MGC was able to seamlessly connect with the deployed base of third party media gateways, with the result that Sify protected its existing investments while positioning its network for future growth and expansion. In addition, the SVI MGC is compatible with other third party media gateways. This means that Sify can deploy additional transcoding capacity with gateways from Squire Technologies or other vendors.

“One of the key benefits of the SVI MGC is the ability to connect to and control a wide range of third party media gateway solutions,” said Zacchary Couldrick, Regional Sales Manager at Squire Technologies. “This delivers outstanding investment protection as existing assets can be maintained. This flexibility delivers outstanding cost benefits and ensures efficient capital management.”

The SVI MGC Media Gateway Controller enables clients to interface their VoIP networks to SS7 PSTN based telephone networks allowing the rapid launch of VoIP services. It provides a secure and proven option for the replacement of legacy solutions while extending the life of deployed Media Gateway products.

Moving from SS7 & Radius to Diameter

Diameter is coming, but probably not as quickly as analysts would have you believe. But even if you are not considering Diameter directly, migration in peer networks may have an impact on your network. It’s time to consider how to protect your network and ensure service continuity while partner networks migrate to EPC and LTE.

Today’s telecommunications infrastructure includes a diverse mix of protocols. Most of our customers are aware of the complexity of interconnecting an array of networks and elements and our role in helping them to achieve a co-ordinated, resilient network. Two common protocols play a hugely significant role in networking today – SS7 and Radius.

SS7, of course, is used for the co-ordination of both user session data (voice, video and so on) as well as interaction with key network elements, such as online charging systems, Intelligent Network entities (such as Service Switching Points and Specialised Resource Functions), while Radius is primarily used for AAA procedures (Authentication, Authorisation and Accounting). This means that an SS7 enabled softswitch might need to use SS7 CAMEL to connect to an online charging server for prepaid subscribers, while at the same time checking a user profile database using Radius.

However, as networks migrate towards LTE, the Evolved Packet Core (EPC) and IMS, many of these functions will be replaced by a new, common protocol: Diameter. The same softswitch may instead need to be able to communicate with Diameter to deliver the same functions.

Diameter is a protocol of growing importance. It provides AAA capabilities as well as satisfying requirements for location and mobility in 3G, LTE, and IMS networks. It has become the most prominent signalling protocol in NGN networks and is expected to replace both SS7 signalling and Radius, which delivers much of this functionality today, just as SIP is increasingly becoming the predominant session control protocol.

Diameter provides a number of advantages over Radius – in particular, in terms of improving network reliability and resilience – which is clearly of fundamental importance if it is truly to replace SS7 connections. In a further post, we shall explore some of the differences, but the fact that concerns us for now is that much of today’s equipment will need to either migrate towards Diameter or else support interconnection with the new protocol.

There have been a number of forecasts regarding the proliferation of Diameter-enabled devices. While it’s clear that Diameter deployments are accelerating, primarily because of LTE network penetration, the general replacement of Radius and SS7 signalling is a massive task and will take many years. After all, it’s more than a decade since analysts forecast the death knell of SS7 and it’s still going strong.

Instead, what we expect is that network operators that are not migrating to IMS or LTE will increasingly need to interconnect with Diameter-enabled devices in other networks. We also expect that many solutions that are today enabled by SS7 and Radius will be declared end-of-life by their vendors. This means that operators that expect to see a more graceful transition to Diameter may be forced to consider network enhancements earlier than anticipated.

Squire Technologies is preparing to meet this challenge. We are investing in solutions that will prolong the life of existing solutions while helping transition to the next generation of networks. It will be essential to support Diameter / SS7 interworking, which will mean that existing SS7-enabled solution can connect to new solutions that support Diameter as they are brought online.

Our expertise will enable us to support operators through this transition and ensure service continuity, even when existing vendors pull the plug on their systems. The migration from Radius and SS7 to Diameter is going to take years. Even if Diameter isn’t in your current thoughts, it is in the thoughts of your peers. It may be that implementing it in your network is several years away – but you need to consider how migration plans from other operators may affect you.

If, for example, you connect to an HLR in another operator’s network, the chances are that this will migrate towards an HSS supporting Diameter within the next couple of years. When this happens, what options will be open to you? That’s what we are here to help with. We can help ensure that you can continue to connect to services and devices, even when they transition to new protocols beyond your control.

If you are concerned about how general migration to Diameter might affect you, why not give us a call to see how we can help?
