Si2400
Rev. 1.3 45
S26 0x26 VTSO
V.22bis 1200 bps scrambled ones length. Minimum length of
time for transmission of 1200 bps scrambled binary ones by a
call mode V.22bis modem after the end of pattern S1 detection
(53.3 ms).
0x0C
S27 0x27 VTSOL V.22bis 2400 bps scrambled ones length low. Minimum length of
time for transmission of 2400 bps scrambled binary ones by a
call mode V.22bis modem (5/3 ms units).
0x78
S28 0x28 VTSOH 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
z
5/3 ms units added to the time
specified by VTSOL).
0x08
S29 0x29 IS Intrusion suspend. When S82[2:1] (IB) = 10
b
, this register sets
the length of time from when dialing begins that the off-hook
intrusion algorithm is blocked (suspended) (500 ms units).
0x00
S2A 0x2A RSO 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).
0xD2
S2B 0x2B DTL 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). In the !7 alarm
mode, this register functions as pulse on time.
0x18
S2C 0x2C DTTO 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). In the !7 alarm mode, this register
functions as pulse off time.
0x08
S2D 0x2D SDL 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). In the !7
alarm mode, this register functions as pulse interdigit time
(10 ms units).
0x0C
S2E 0x2E RTCT V.23 reverse turnaround carrier timeout. Amount of time a slave
mode V.23 modem will search for carriers during potential
reverse turnaround sequences (5/3 ms units). In the !7 alarm
mode, this register functions as Handshake End to TX Data
delay (10 ms units).
0x84
S2F 0x2F FCD FSK connection delay low. Amount of time delay added
between end of answer tone handshake and actual modem
connection for FSK modem connections (5/3 ms units).
0x3C

Notes:
1. These registers are explained in detail in the following section.
2. The ring detector will only detect ringing if the ring burst on/off times meet the settings in MNRP, MXRP, MNRU, ROT,
and REP.
