410i. Although ISDN routers

are used for both data and

voice connections, testing

focused exclusively on bench-

marks using data traffic only.

Testing was performed in

February 1999.

Results show the 3Com LAN

Modem supports a wide range

of applications via Network

Address Translation (NAT). It

was the only ISDN router that

featured support for both

multiple destination networks

and “data call bumping,” or the

ability to reallocate an ISDN B

channel.

Additionally, 3Com’s LAN

Modem was one of only two

products that offered support for

all the GUI features evaluated

in this project, but unlike other

products, the 3Com LAN

Modem did not require extra

management software. Its Web-

based GUI required the least

number of steps for the initial

“out-of-the-box” configuration.

Finally, benchmarks of data com-

pression throughput showed that

the 3Com LAN Modem’s imple-

mentation delivered effective

application throughput at a level

higher than the rated link speed.
