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 2701/D (X.21 version) provides DTE/DCE functionality in the same standalone or 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.
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!
