EXECUTIVE SUMMARY

VOIP: A Comprehensive Competitive Analysis of Media Gateways

As the telecom recovery begins, incumbent telecom carriers face severe challenges, including the continued loss of telephony lines and minutes to wireless operators, the need to accelerate broadband rollouts in the face of new competition from cable companies, the regulatory mandate to unbundle local loop elements, and new long-distance competition from specialist VOIP carriers.

Incumbent telcos need new VOIP infrastructures to meet these challenges, and they now have the knowledge and spending power to start buying and deploying them as they migrate from aging Class 5 circuit-switched networks to a packet-switched infrastructure. One critical component in any VOIP infrastructure deployment is the media gateway – the network device that takes conventional time-division-multiplexed voice signals and converts them to IP.

VOIP: A Comprehensive Competitive Analysis of Media Gateways is the most detailed and comprehensive analysis of media gateway products undertaken to date. In three key product categories – central-office media gateways, digital loop carrier media gateways, and trunk media gateways – this report provides granular information, in matrix format, on every important aspect of the functionality and performance of each vendor's offering. Along with providing detailed product specs, this report rates media gateway products based on a unique weighted system.

In addition to delivering exhaustive product data, the report includes a unique rating system that allows for the industry's first-ever ranking of media access gateways in these four product categories:

Copper line access media gateways
GR.303/V.5 access media gateways
Third-generation digital loop carrier (3G DLC) access media gateways
Trunk media gateways


The scoring system used to determine product ratings is described in remarkable detail, showing product ratings in dozens of discrete categories, in addition to delivering overall ratings.

Key Findings

Key findings from the report include the following:

Access media gateways are of pivotal importance in the converged next-gen network, as they replace the telephone line cards of legacy TDM switches. Much of the Class 5 migration thought process is going into graceful migration strategies from legacy TDM switch line cards to VOIP access media gateways.

Access media gateways will represent the bulk of the investment in the next-gen network. CO-based access media gateways currently account for 65 percent to 75 percent of the target market in the U.S. that has not devolved into outside plant.

The biggest vendors in the access media gateway market don't necessarily have the best products. Access and trunk media gateways from Alcatel, Cisco, Lucent, Nortel, and Siemens earned generally respectable scores in our product ratings, but they fell short of being at the head of the class.

Vendors from Asia are now making some of the best media gateway products on the market. Samsung and Huawei earned solid ratings for their access media gateway offerings, while UTStarcom earned the third-highest mark overall for its trunk media gateway product.

For copper line access media gateways, products from Marconi rated the highest in our evaluation. Marconi's AXH-600-E came out on top by quite a margin, with its smaller sibling, the AXH-600-S4, squeezing into second place. The former won on the basis of its solid all-around performance, the only weakness being in the area of switching and QOS. The smaller gateway lost ground primarily on scaleability. Samsung's AceMAP came a very close third with a good all-around performance, again dropping most points on scaleability.

For GR.303/V.5 access media gateways, products from General Bandwidth, Alcatel, and Huawei earned the highest scores. General Bandwidth's G6 product did very well on scaleability, protocols and codecs, and signaling. Alcatel's 7510 and Huawei's UMG 8900 also did well on scaleability, and otherwise had good all-around performances.

The 3G DLC access media gateway enables the most graceful Class 5 migration to VOIP possible. The most useful configuration is the BLC (broadband loop concentrator), where any line can be POTS or DSL, and all POTS traffic is packetized for backhaul to a softswitch or via an inverse media gateway to a legacy Class 5 TDM switch. In this configuration any line can be turned up for DSL automatically through the management system, and any POTS line can be routed to a legacy switch or a softswitch.

The trunk media gateway requirement for high-density processing is creating a good opportunity for specialist vendors to capture market share. Since they are required in fewer locations than access gateways, trunk media gateways are all about high density in terms of trunks handled, codecs, signal processing, and call processing.

Telcos do not need to be locked into their existing TDM switch suppliers for trunk media gateways. The leading independent products interwork with a wide range of softswitches, giving carriers the important option of using best-of-breed products from different vendors in their networks.
