Modem Communication
Communication with the OCM-3 over an answer back telephone modem is relatively
straight forward. For modem communication over conventional telephone lines, a
maximum of 1200 or 2400 baud is recommended. Generally, a lower baud rate is
more reliable on noisy lines. Modem should be self answering and data checking
capability turn on.
