Allied Telesyn rounds out line with CPE play

Allied Telesyn this week is launching a series of residential gateways the company says are aimed at filling out its fiber-to-the-home platform.

At the home, the company has developed a family of residential gateways for carriers offering voice, data and video services. The 600 series of gateways includes the typical layer 2 capabilities including passing along all three services. However, Allied also is introducing layer 3 functions into the product such as network address translation (NAT), a stateful inspection firewall and virtual server/DMZ.

"It kind of rounds out our fiber-to-the-home application," said Michael Selman, applications manager for Allied Telesyn. "The CPE is often the most expensive part of these rollouts outs so it’s a pretty strategic element."

The addition of layer 3 functions gives carriers the ability to offer new data services and an enhanced voice-over-IP feature set. Additionally, the unit has three 10/100 Ethernet LAN ports, one 10/100FX/LX single-mode and multi-mode Ethernet WAN port and two integral FXS ports for standard analog phones, faxes or modems.

On the voice side, the unit is supporting all three major VoIP protocols, SIP, MGCP and H.323. For video, the gateways support Internet Gateway Message Protocol v1 and v2 snooping and proxying and supports 16 VLANs, which keep video streams clear during simultaneous Web surfing of VoIP traffic.

"There are some real challenges with effectively deploying video over IP," Selman said.
