V.90 Support
The Model RM356 router is designed to take advantage of the V.90 standard for transmission of
data over analog telephone networks.
One advantage of using a dial-up modem interface to connect routers is that the connection is set
up only if data needs to be sent to the remote network. The router sets up a call, transfers the data,
then hangs up automatically when the connection is no longer needed.
TCP/IP Support
The Model RM356 router supports the Transmission Control Protocol/Internet Protocol (TCP/IP)
and Routing Information Protocol (RIP).
For further information about TCP/IP, refer to “Basic Router Concepts ” on page 1-5 .
IP Address Masquerading by Dynamic NAT+
The router allows an entire department of networked PCs to share an Internet account using only a
single IP address, which may be statically or dynamically assigned by your ISP. This technique, an
extension of network address translation (NAT), is known as IP address masquerading and
typically allows the use of a very inexpensive ISP account.
Automatic Configuration of Attached PCs by DHCP
The router can dynamically assign network configuration information including IP, gateway, and
domain name server (DNS) addresses to attached PCs on the LAN using the Dynamic Host
Configuration Protocol (DHCP). This feature greatly simplifies configuration of LAN-attached
workstations.
