Mobile Video: Dialogic Solutions Doubles Backhaul Capacity


Dialogic has introduced a solution that it says can double the capacity of service providers' existing backhaul infrastructure. The company is showing the I-Gate 4000 SBO this week at Mobile World Congress in Barcelona.


The company leveraged its no degradation voice optimization technology in the solution, which comes in the form of a 1RU box, explained Dawn Hogh, vice president of product marketing. With this solution, network operators can keep their same infrastructure and just add one box each on towers at both ends of the link, she added.

Of course, one common alternative of that is to add more fiber for backhaul, but that’s a much more expensive proposition, she continued. So this is a nice solution, particularly in emerging markets where most service providers are either leasing capacity or have very limited infrastructure, she said.

"We tested Dialogic's (News - Alert) solution both in the lab and in a field trial, and saw a significant bandwidth savings in our network," said Cayetano Carbajo, technology director at Telefónica.  "Not only were we impressed with the quality of experience, but the solution really does take bandwidth optimization to the next level. It delivers two-fold benefits – significant cost savings and growth opportunities for new subscribers."

Dialogic recently completed field trials of the solution, which is expected to be generally available this quarter. The company, which declined to provide details on pricing for the new solutions, sells directly to service providers, but there is an opportunity to sell this solution through other infrastructure suppliers as well, noted Hogh.

The I-Gate 4000 SBO supports a wide range of traffic types and interfaces, including IP- and ATM-based iub, Abis, Native IP, VoIP, PCM signals and pseudowire (TDM over IP). Topologies for both microwave and satellite transmissions are also supported, including point-to-point, point-to-multipoint, drop and continue, ring and data offload.
