Envoy Router^™

The Envoy^™ and Envoy 1U^™ are low-cost routers that provide a lightweight aluminum chassis, 266 MHz CPU, 128 MB RAM, two on-board 10/100 ethernet ports, two Mini PCI slots, one USB bus with two internal ports, flash storage, and no cooling fans. Both Envoy chassis are designed for low-cost, small form-factor CPE installations with operating temperatures from 0° to 55° C. The extended temperature version can be deployed in outdoor enclosures with operating temperatures from –10° to 65° C, and options for 24 VDC and –48 VDC power are also available.

The Envoy is a set-top chassis that supports one DB-style and two RJ-style expansion ports, while the Envoy 1U is a rackmount chassis that supports two DB-style and three RJ-style expansion ports. Expansion options currently include network cards for 10/100 ethernet, T1/E1, and synchronous serial (RS232, RS422, X.21 and V.35).

Like all ImageStream Routers, Envoy routers take advantage of the ImageStream Linux^™ router distribution, which provides support for NAT firewall security, IPsec and SSL virtual private networks (VPNs), quality of service (QoS), VLAN tagging, VRRP for LAN failover, dynamic routing, packet filtering, bridging, peer-to-peer traffic control, and more. ImageStream Linux also includes the Inetics driver component architecture (IDCA), which supports WAN protocols including PPP, Cisco HDLC and frame relay, as well as most multilink protocols including MLPPP, MLFR and CEF.
