S-Register Summary (Continued)
Function
V.22bis 2400 bps scrambled ones length high. Minimum
length of time for transmission of 2400 bps scrambled
binary ones by a call mode V.22bis modem (256 x 5/3 ms
units added to the time specified by VTSOL).
Intrusion suspend. When S82[2:1](IB) = 10b, this register
sets the length of time from when dialing begins that the
off hook intrusion algorithm is blocked (suspended)(500
ms units).
Receive scrambled ones V.22bis (2400 bps) length.
Minimum length of time required for detection of
scrambled binary ones during V.22bis handshaking by the
answering modem after S1 pattern conclusion (5/3 ms
units).
V.23 direct turnaround carrier length. Minimum length of
time that a master mode V.23 modem must detect carrier
when searching for a direct turnaround sequence (5/3 ms
units).
V.23 direct turnaround timeout. Length of time that the
modem searches for a direct turnaround carrier (5/3 ms
units added to a minimum time of 426.66 ms).
V.23 slave carrier detect loss. Minimum length of time
that a slave mode V.23 modem must lose carrier before
searching for a reverse turnaround sequence (5/3 ms
units).
V.23 reverse turnaround carrier timeout. Amount of time
a slave mode V.23 modem searches for carriers during
potential reverse turnaround sequences (5/3 ms units).
FSK connection delay low. Amount of time delay added
between end of answer tone handshake and the actual
modem connection for FSK modem connections (5/3 ms
units).
FSK connection delay high. Amount of time delay added
between end of answer tone handshake and the actual
modem connection for FSK modem connections (256 x
5/3 ms units).
Receive answer tone length. Minimum length of time
required for detection of a CCITT answer tone (5/3 ms
units).
The time after going off hook when the loop current sense
bits are checked for overcurrent status (5/3 ms units).
Answer tone length when answering a call (5/3 ms units).
This register is only used if TATL (1E) has a value of zero.
Receive scrambled ones V.22 length (5/3 ms units).
Minimum length of time that an originating V.22 (1200
bps) modem must detect 1200 bps scrambled ones during
a V.22 handshake.
Second kissoff tone detector length. The security modes,
A1 and !1, echo a “k” if a kissoff tone longer than the
value stored in SKDTL is detected (10 ms units).
