S REGISTERS

8-3

S0 Rings to Answer

Default : 2 (Answer on second ring)

Range : 0 to 255 (Stored in NVRAM)

Establishes the number of rings that the modem must receive before the auto answer

sequence is started. Values of 0 ensure the DPX-213 never answers (the value for

Originate Mode) while values from 1-255 will enable auto answer.

NOTE: When in leased line Mode, S0=0 forces the DPX-213 into Originate Mode and

S0=(1-255 but not zero) forces the DPX-213 into Answer Mode. For a point to

point leased line application, you must set ATS0=0 at one end and ATS0=1 to

255 at the other end; n must NOT be 0 at both ends.

S1 Ring Count

Default : 0
