2.2 DESCRIPTION
The Model 2707/I receives clear channel E1/G.703 (2.048-Mbps) data from the telco's digital data network. The Model 2707/I terminates the G.703 telco interface and converts the data for transmission to a user- oriented 10Base-T (802.3) Ethernet interface.
The Ethernet (Model 2707/I) supports an integrated 10Base-T (802.3) Ethernet port with transparent bridging capability for IP, IPX, DECnet, NetBIOS and other layer-3 protocols. The 2707/I attaches to the LAN and intelligently bridges data traffic to the large central site router through the telco's leased line network. The 2707/I supports PPP (RFC 1661) and BCP (RFC 1638).
The Model 2707/I is a 10Base-T bridge that operates over G.703 lines. It uses MAC learning and forwarding to provide seamless LAN-to-LAN connectivity. As a result, corporate enterprises can connect their servers to a pair of NTUs and automatically forward data packets that are meant for the remote network. Local packets are filtered and passed only to the local LAN.
