Chapter 44 Service Control

44.11.1 a managementAT Command Strings

For regular telephone lines, the default Dial string tells the modem that the line uses tone dialing. ATDT is the command for a switch that requires tone dialing. If your switch requires pulse dialing, change the string to ATDP.

44.11.2 DTR Signal

The majority of WAN devices default to hanging up the current call when the DTR (Data Terminal Ready) signal is dropped by the DTE. When the Drop DTR When Hang Up check box is selected, the ZyWALL uses this hardware signal to force the WAN device to hang up, in addition to issuing the drop command ATH.

44.11.3 Response Strings

The response strings tell the ZyWALL the tags, or labels, immediately preceding the various call parameters sent from the serial modem. The response strings have not been standardized; please consult the documentation of your serial modem to find the correct tags.
