PRODUCT DESCRIPTION
Black Box's DSL LAN Extender 400 is a SDSL bridge or router, which offers standard compliance high-
speed symmetrical access for Internet services with an ordinary telephone wire pair. It functions as a
remote LAN-to-LAN application.
The DSL LAN Extender 400 operates in SDSL mode with CAP encoding. In the SDSL mode, it provides
symmetrical 4.64 Mbps performance at distances up to 7,500 feet (2.28 Km) using a 26 AWG wire pair.
The DSL LAN Extender 400 provides an ideal solution for small offices and home offices (SOHO) to
reap the benefits of broadband connections to the tenant complex or neighborhood. By over subscribing
the expensive broadband connection, all tenants can share economical always-on Internet access, which
eliminates dial - up requirements, without sacrificing the individual access privacy of sharing a typical
Ethernet LAN network. It supports full IP routing for RIP-1 and RIP-2 together with the convenience of
IP address management with NAT, built-in DHCP server, and transparent Bridging.
