Appendix D - AT Command Summary
RF300E/RF310E 139
analog calls for the given amount of time (n) for that analog port. Analog calls that are
received by that port while calls are being held off will not be rejected nor will a ring
be given. Rather the analog call will be held in an alerting state until *!Hn times out
at which point the call will begin the normal ringing process. Analog calls originated
from that port while the *!Hn timer is running will abort the timer and the call will go
out immediately. This command can be very useful for certain RAS environments
that require at least 1 second to initialize a port after a call has disconnected (such
as Citrix and Novell). See the troubleshooting section below for more information
about the use of this feature.
D.2 S-Registers
S-registers are sections of memory in which values are stored that affect how the TA operates. S-
registers are so-called because each has a name that begins with the character S. Use the Sr=n
command to assign a value to an S-register or use the Sr? command to read the current value of an
S-register. S-registers are stored in non-volatile RAM (NVRAM) by using the &W0 command.
ATZ<CR> restores S-registers to values stored in NVRAM if any were stored using the &W0
command, otherwise they revert to factory default settings in ROM. Table D-2 summarizes the
available S-registers and their function.
