NOTE: The omni.net LCD/LCD+M does not support network
independent clock compensation. The synchronous timing source
must be supplied by the omni.net LCD/LCD+M , which is phase
locked to the network synchronous clock.
When in V.25bis command mode, the omni.net LCD/LCD+M supports the bit-oriented HDLC
(High-Level Link Control) synchronous protocol which most synchronous communication links
use. Use
AT*Ii
to enable V.25bis commands. For synchronous applications the TA is set for use
with one application, in normal situations. Save the desired settings in the power-on profile and the
TA will start up in synchronous mode with V.25bis enabled. A special command set RST is
provided to get the TA back to asynchronous AT command mode from V.25bis mode.
When the TA is used as a DCE device with a router or mainframe system, use the following
command string for best results:
