Allied Telesyn AT RG623LX

Allied Telesyn AT RG623LX ... feature set. It offers a potent combination of wirespeed Layer 2 switching between VLANs as well as high performance Layer 3 routing between VLANs in one highly cost effective unit.

The AT-RG600 series 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 e-mail server can sit beyond the NAT and appear like being on the public interface. The AT-RG600 series NAT supports the most popular protocols and applications including NetMeeting (H.323 and SIP), IPSec and PPTP.

The AT-RG600 series offers the possibility to limit the egress and ingress bandwidth on each port and queue with a granularity of 32kbps. This feature allows the service operator to offer differentiated services to each customer and protect its network from malicious packet flooding.

The AT-RG600 series offers a choice of Voice over IP signaling methods, namely H.323, SIP and MGCP including NCS 1.0 profile. This multiple protocol support provides maximum flexibility for service providers, allowing them to provide an IP telephony service based on cost and feature set, rather than being limited by the protocol used.

Video streaming offers unique features to optimize the delivery of Video contents to customers, namely VLAN, IGMP snooping and proxying. The AT-RG600 series supports full IGMP snooping capability (v1/v2) and individual LAN ports can receive different multicast transmissions e.g. different movies or TV channels. The AT-RG600 series 'snoops' IGMP packets in-transit, so it knows which port to forward the particular multicast data to. This results in high-quality, high bandwidth video streaming without affecting Internet surfing or IP telephony on adjacent ports.

The AT-RG600 series is designed for high volume deployment, this is reflected in the Zero Touch Configurator (ZTC), whereby no user intervention is required when installing a unit. ZTC is a distributed configuration system based on the industry standard Lightweight Directory Access Protocol - LDAP. ZTC provides intelligent and automatic configuration of remote RG units. The ZTC client in the RG initiates the download process on power up, or on expiration of its DHCP lease timer. ZTC provides secure authentication of client devices, resilience through distributed server operation and in-built scalability for very large networks.
