OK <value> = 0-7
ERROR Otherwise.
When on-hook, if the line is in use and an ATDT is issued, the modem will not go off-hook
and will return with the message LINE-IN-USE.
When off-hook and either an extension is picked up or a line reversal is detected, the
modem will drop the connection. The disconnect reason in register S86=25 (also defined
for #UD). The user must flash the hook in order to get a dial tone because the remote
server will be retraining.
If local handset is picked up while modem is off-hook, modem will do a link-disconnect,
flash the hook for 1.5 seconds, then connect local handset to the line. Now, the user dial
tone is on the local handset. Disconnect reason S86=25.
When in voice mode and an extension is picked-up, a <DLE>P is sent to the DTE. When
the modem is off-hook, a line reversal may also be detected in which case a <DLE>l is
sent to the DTE.
In voice mode, there is no blocking of ATDT when the line is in use. Also, there is no
automatic hang-up in voice mode as in data mode. There is only the above stated <DLE>
shielding event reporting.
Line-In-Use (Enabled by AT-STE=1, AT-STE=3, AT-STE=5, or AT-STE=7)
Case 1: Telephone Line is in Use
If an ATDT, ATDP or ATDL is issued while Line-In-Use detection is enabled and the
telephone line is in use, the modem will immediately return the message LINE-IN-USE to
the DTE without going off-hook, and then return to command mode.
Case 2: Telephone Line is in Use But Disconnected
If an ATDT, ATDP or ATDL is issued while Line-In-Use detection is enabled and the
telephone line is NOT in use, the modem will go off-hook after a short pause, then
respond with CONNECT or NO CARRIER message.
Case 3: Telephone Line is Not Connected to Modem
If an ATDT, ATDP or ATDL is issued while Line-In-Use detection is enabled and the
telephone line is not connected, the modem will go off-hook momentarily, go back on-
hook, then respond with NO DIAL TONE message.
Extension Pick-up (Enabled by AT-STE=2, AT-STE=3, AT-STE=6, or AT-STE=7):
Case 1: Modem off-hook, Local Handset Goes Off-Hook
If the local handset goes off-hook while the modem is in a data connection, the modem
will then send a GSTN Clear down to the remote modem and then go on-hook. The
modem will then send a NO CARRIER message to the DTE. A result code of 25 will be
left in S86 register.
Additional hardware may be required to support these features.
