Circuit Card Description and Installation
All S registers may be changed with the exception of S1, the Ring count. If
an attempt is made to change this parameter, the command is accepted but no
action is taken. The Ring count is the number of 6-second intervals that have
expired since an inbound call has been received. The current count may be
displayed through the Display S register command but cannot be altered After
a call is dropped, the Ring counter is set back to 0.
If, when using the display or alter commands, no register or value number is
input, the number 0 is used. For example, ATS? is equivalent to ATS0.
Allowable S registers Table 156 shows the supported S registers allowed by
the DAC. This table shows the register number, the range accepted (decimal
values shown), and a description of the register. Whenever a register value is
changed, the DAC checks for validity. If the value entered is not within the
allowed range, all processing ceases and no command processing following
the invalid entry is accepted. The DAC sends an ERROR result message.
