The NetLink Model 2720 Series T1/FT1 CSU/DSU provides high speed WAN connectivity in a compact (1.50H x 4.17W x 5.84D inches) full feature standalone package.
The Netlink 2720 is an excellent choice for terminating leased lines, Frame Relay backbones, Internet access, and LAN-to-LAN services. When terminating a T1- dedicated digital circuit, the NetLink 2720 supports nx56/nx64 kbps T1 framing and converts to V.35, RS-530, or 10Base-T Ethernet interfaces.
The Netlink 2720 supports D4/ESF framing options and AMI/B8ZS/B7ZS 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.
The model 2720/I (10 Base-T Ethernet Bridge) is particulary suited for LAN-to-LAN connection without the need for routers! MAC forwarding and PPP/BCP built-in bridging provides seamless connection over the T1 link.
The PPP/BCP features also enable customers to extend a router's serial interface and connect to a remote Ethernet LAN over the T1 network.
