- Remote Router Porting with Patton's Ethernet-over-E1 Bridge
Patton Electronics introduces a new way of interconnecting remote branches to a Main Office LAN using the Model 2701/I Ethernet-over-E1 Bridge. Called "Remote Router Porting" (RRP), it offers network managers and integrators a simple and economical way for LAN-to-LAN deployments.
At the branch office, RRP replaces the traditional router and CSU/DSU solution with Patton's Patton's Ethernet-over-E1 Bridge, which includes integrated E1 and 10Base-T transparent bridging. This unit allows for high-speed PPP data connections across the Wide Area Network at scalable data rates of nx56/nx64kbps up to 2.048 Mbps, and also connects directly to the 10Base-T branch office LAN at 10Mbps. The 2701/I transparently forwards Ethernet packets to a headquarters LAN based on their destination MAC address.
At headquarters, RRP builds on the bridging capabilities of a router to extend their serial or WAN ports across town or across the country. In order for the central routed network to connect to a remote branch Ethernet network, the serial or WAN interface of the router needs to be configured as a PPP IP half-bridge. In this configuration the Ethernet-over-E1 Bridge sends bridge packets (BPDUs) to the router's WAN interface. The router will then look at the layer-3 address information and will forward these packets based on its IP address. The router's port, connected through the E1 network and Ethernet-over-E1 Bridge, appears as a virtual interface at the branch office network.
The Model 2701/I Ethernet-over-E1 Bridge supports G.704 framing, and AMI and HDB3 line coding. Data rates, framing, and coding options are programmed by DIP switches or from a VT-100 terminal with menu-driven software. A full range of system and diagnostic features make setup simple and easy
- Today's customers require low-cost network solutions that deliver high speed connections to the Internet and Corporate Intranets while supporting videoconferencing and many other wide-area services. The NetLink Model 2701 E1/Fractional E1 NTUs satisfies those needs.
The NTUs terminate G.703/G.704 services for all n x 64 kbps rates and connect to the customer's router, FRAD, CODEC, and switches with a 10Base-T Ethernet interface.
Our Ethernet version, the Model 2701/I offers 10Base-T bridging and supports PPP and 802.1q VLAN tagging, passing vLAN-tagged packets of up to 1522 bytes. These features enable customers to extend a router's serial interface and connect to a remote 10Base-T Ethernet LAN (see diagram below). The 2701/I uses MAC learning and forwarding to provide seamless LAN-to-LAN connectivity.
Built for universal mounting, the Model 2701 comes in three distinct flavors covering desktop installation, wall mount, DIN rail mount (optional kit), and telco rack mount. You can now take your E1 anywhere!
