25bis Command Set, Cic, Dic | ZyXEL Communications omni series

There are two modes of synchronous operation:

1.Asynchronous commands, synchronous data (AT&M1): The omni accepts AT commands in asynchronous mode. Once the call is connected, it enters synchronous mode for data transmission.

2.Synchronous mode (AT&M3*I1): The omni accepts synchronous commands from V.25 bis or a PC with an add-on synchronous card, and exchanges data synchronously with a remote TA.

ONote: The omni does not support network independent clock compensation. The synchronous timing source must be supplied by the omni , which is phase locked to the network synchronous clock.

When in V.25bis command mode, the omni 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 main-frame system, use the following command string for best results:

AT&S1&M3*I1&W0Z0
