Technical Details for Allied Telesyn AT-RG656LH Broadband Residential Gateway

Allied Telesyn AT-RG656LH Broadband Residential Gateway ... series. It adds powerful Layer 3 capabilities as well as enhanced VoIP features set. Moreover, it offers optical connection to the WAN.

The RG600 series supports up to 16 IEEE 802.1Q tagged VLAN operation across its 6 x 10/100Mbps switch ports. Hence, it offers a powerful combination of wirespeed Layer 2 switching between VLANs as well as high performance Layer 3 routing between VLANs in one highly cost effective unit.

AT-RG656 offers a comprehensive range of optical interfaces in order to provide connection to remote users.

AT-RG656SH equips 100FX for application on multi-mode fibers, while the AT-RG656LH can enhance the covering distance by use of a couple of single-mode fibers.

The application of 100FX bi-directional optical interface on the AT-RG656BD requires only one single-mode fiber for the connection to the WAN. The transmit wavelength is 1310 nanometers and the receive wavelengths is 1510 nanometers.

The fiber optic connector is SC style for both dual and single fiber versions.

The AT-RG656 has an integral Stateful Inspection Firewall with NAT and Denial of Service intrusion detection and blocking for protecting customer networks. Each VLAN can be configured to be external, internal or DMZ. With the Virtual Server features, a web or email server can sit beyond the NAT and appear like it is on the public interface. The ATRG656 NAT supports the most popular protocols and applications including NetMeeting (H.323 and SIP), IPSec and PPTP.

The AT-RG656 offers the possibility to limit the egress and ingress bandwidth on each port and queue with a granularity of 64kbps. This feature allows the Service Operator to offer differentiated services to each customer and protect its network from malicious packet flooding.
