IBM 7858 Professional Modem

• Flexible operations in both

synchronous and asynchronous

mode

• Compatibility with a wide range

of ITU standards

• Automatic adaptation to

changes in network environ-

ment

• High-throughput telecommuni-

cations over switched and

leased lines

• Flexible setup, operation and

management

• Enhanced system security

Meets the demands of today's business environment

for reliable high-throughput telecommunications

The IBM 7858 Model 336 is a stand-alone modem with Link Problem Determination

Aid (LPDA) support for those environments requiring centralized management from

a NetView console. It allows your data terminal equipment (DTE) to communicate

with other DTEs using a synchronous or asynchronous protocol. The 7858 operates

in duplex mode at line speeds of up to 33.6 Kbps over switched and 2-wire or 4-wire

leased lines.
