Overview  

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 V.35, X.21, EIA-530, or 10Base-T Ethernet interface.

The Model 2701RC/D/D (X.21 version) provides DTE/DCE functionality in a rack-mount package. This added versatility supports operation in X.21 DTE applications (see diagram below) where an NTU is needed to terminate G.703/G.704 and provide X.21/V.11 data to a multiplexer.

The Model 2701RC/A/I is a 10Base-T bridge that operates over G.703/G.704 lines. It 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). 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 Model 2701s and automatically forward data packets that are meant for the remote network. Local packets are filtered and passed only to the local LAN.
