Data transmission
•
Timers start automatically after 10 seconds if a call-connect message is
not received (non-ISDN or off-net calls).
•
Timers start (or reset) when the called number answers.
NI-1 and Meridian 1 modes only. This feature displays the time in 12-hour
format. If power fails, the date and time must be reset.
The M5317T telephones support PCM voice on either B-channel.
Circuit-switched data calls on the M5317TDX may be made using the other
B-channel. The NT T-link or standard V.120 protocols are used to convert the
serial data from the RS-232C port to the 64 Kbit/sec stream (rate adaption)
for transmission on the B-channel.
The M5317TDX Data Option is logically separate from voice calls. The
Hayes protocol is used to control circuit-switched data calls, and X.25
packet-switched calls on D-channel are supported with X.3, X.28, X.29
control protocol.
