Modem 3600
Description
Functional
The Modem 3600 processes serial asynchronous data from a DTE at all
standard rates from 300 bps to 230.4 kbps*, and serial synchronous data
at rates from 300 to 33.6 kbps. Transmission can be over either dial-up
lines or either two- or four-wire leased lines. The maximum line speed is
33.6 kbps. Built-in test features can determine system performance and
isolate faults in the data link. Operation and configuration are controlled
by the front panel LCD, the AT command set, or the V.25 bis command
set.
