FIELD DESCRIPTION
AT Command
Strings:
Dial Enter the AT Command string to make a call.
Drop Enter the AT Command string to drop a call. “~” represents a one second wait,
for example “~~~+++~~ath” can be used if your modem has a slow response
time.
Answer Enter the AT Command string to answer a call.
Drop DTR When
Hang Up
Press the [SPACE BAR] to choose either Yes or No . When Yes is selected (the
default), the DTR (Data Terminal Ready) signal is dropped after the “AT
Command String: Drop” is sent out.
AT Response
Strings:
CLID (Calling Line
Identification)
Enter the keyword that precedes the CLID (Calling Line Identification) in the AT
response string. This lets the ZyXEL Device capture the CLID in the AT
response string that comes from the WAN device. CLID is required for CLID
authentication.
Called Id Enter the keyword preceding the dialed number.
Speed Enter the keyword preceding the connection speed.
Call Control
Dial Timeout (sec) Enter a number of seconds for the ZyXEL Device to keep trying to set up an
outgoing call before timing out (stopping). The ZyXEL Device times out and
stops if it cannot set up an outgoing call within the timeout value.
Retry Count Enter a number of times for the ZyXEL Device to retry a busy or no-answer
phone number before blacklisting the number.
Retry Interval (sec) Enter a number of seconds for the ZyXEL Device to wait before trying another
call after a call has failed. This applies before a phone number is blacklisted.
Drop Timeout (sec) Enter a number of seconds for the ZyXEL Device to wait before dropping the
DTR signal if it does not receive a positive disconnect confirmation.
Call Back Delay
(sec)
Enter a number of seconds for the ZyXEL Device to wait between dropping a
callback request call and dialing the corresponding callback call.
