Introduction

When the single-channel ISDN line utilization exceeds a configurable threshold, the router can 
automatically establish an additional ISDN call to provide additional bandwidth. During heavy 
traffic, the two 64 Kbps B channels are combined using Multilink PPP to provide a fast 128 Kbps 
pipe. When traffic slows down, one of the B channels is idled to save toll charges. The router also 
reverts back to one B channel for data when an analog port is used.

The Model RT338 router supports the Transmission Control Protocol/Internet Protocol (TCP/IP) 
and Routing Information Protocol (RIP), which ensures that ISDN connections are established 
only when passing data.

The Model RT338 router lets several networked PCs share an Internet account using only a single 
IP address, which may be statically or dynamically assigned by your Internet service provider 
(ISP). This technique, an extension of Network Address Translation (NAT), is also known as 
IP address masquerading. It lets you use an inexpensive single-user ISP account.

Although NAT prevents Internet locations from directly accessing the PCs on the LAN, the router 
lets incoming traffic be forwarded to specific PCs based on the service port number of the 
incoming request.

The Model RT338 router dynamically assigns 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 PCs.
