Premise: Buyers of dial-on-demand

ISDN routers for small office/home

office (SOHO) environments need to

be concerned with four key issues

when making a purchasing decision.

An ISDN router must offer support

for a variety of applications through

Network Address Translation (NAT)

so that multiple clients can share a

single ISP account and IP address

from one location. An ISDN router

should provide a graphical user

interface (GUI) to assure quick and

easy device configuration since

SOHO users are unlikely to have

professional network managers

available. It should further allow

connectivity to multiple network

destinations simultaneously to

exploit the potential of ISDN’s two B

channels. Finally, high-performance

levels of application throughput

should be considered to guarantee

the best business productivity.
