Function
Busy tone delta. Detector Time Delta (10 ms). A busy tone is
detected to be valid if (BTON – BTOD < on time < BTON +
BTOD) and (BTOF – BTOD < off time < BTOF + BTOD).
Ringback tone on. Time that the ringback tone must be on
(53.333 ms units) for ringback tone detector.
Ringback tone off. Time that the ringback tone must be off
(53.333 ms units) for ringback tone detector.
Detector time delta (53.333 ms units). A ringback tone is deter-
mined to be valid if (RTON – RTOD < on time < RTON + RTOD)
and (RTOF – RTOD < off time < RTOF + RTOD).
Dial tone detect time. The time that the dial tone must be valid
before being detected
(10 ms units).
before being detected (10 ms units).
Transmit answer tone length. Answer tone length in seconds
when answering a call (1 second units).
Answer tone to transmit delay. Delay between answer tone end
and transmit data start (5/3 ms units). In the !7 mode, this is a bit-
mapped register.
Unscrambled ones length. Minimum length of time required for
detection of unscrambled binary ones during V.22 handshaking
by a calling modem (5/3 ms units).
Transmit scrambled ones delay. Time between unscrambled
binary one detection and scrambled binary one transmission by
a call mode V.22 modem (53.3 ms units).
Transmit scrambled ones length. Length of time scrambled ones
are sent by a call mode V.22 modem (5/3 ms units).
V.22X data delay low. Delay between handshake complete and
data connection for a V.22X call mode modem (5/3 ms units
added to the time specified by VDDH).
V.22X data delay high. Delay between handshake complete and
data connection for a V.22X call mode modem (256 5/3 ms
units added to the time specified by VDDL).
S1 pattern time length. Amount of time the unscrambled S1 pat-
tern is sent by a call mode V.22bis modem (5/3 ms units).
