AT Commands for CX930xx Modem Reference Manual
3-4 Conexant 102752B
-SCID - Snooping CID (Type II)
This command allows the modem to snoop a telephone line for Type II CID and relay
this information in order to report to DTE while on-hook. It is similar in functionality
with the standard Type II CID, which fetches CID information while off-hook. The main
difference is that the -SCID command requires equipment with Type II CID capability
connected in parallel with the modem, and hence the name Snooping CID. It will not
work without the CID equipment.
Syntax
-SCID=<pmode>
Defined Values
<pmode> Decimal number corresponding to the selected option.
0 Disables snooping mechanism only. It does not
disable Type I CID nor Line In Use features.
(Default)
1 Enables snooping mechanism, Type I CID with
formatted presentation to the DTE, and Line In
Use features. The expected pairs are date, time,
name, and caller code (telephone number.)
Forces +VCID=1 and sets the Line In Use bit in
–STE command.
2 Enables the snooping mechanism, Type I CID
with unformatted presentation to the DTE, and
Line In Use features.
Forces +VCID=2 and sets the Line In Use bit in
–STE command.
Example:
The following command sequence demonstrates how the –SCID affects both Line In Use
and Type I CID features:
AT Command Snooping CID Type I CID Line In Use Comment
ATZ -SCID: 0 +VCID: 0 -STE: 0 All three features are disabled
AT-SCID=1 -SCID: 1 +VCID: 1 -STE: 1 Enables all three features
AT-SCID=0 -SCID: 0 +VCID: 1 -STE: 1 Disables SCID only
AT-STE=2
1
-SCID: 0 +VCID: 1 -STE: 2 Enables extension pick-up while
disabling Line In Use
AT-SCID=2 -SCID: 2 +VCID: 2 -STE: 3 Enables all three features with
unformatted CID info. Toggles Line In
Use bit

.
1. Line In Use is bit 0 and extension pick-up is bit 1. See -STE command.
2. The –SCID command only toggled the Line In Use bit and left the extension pick-up bit as is.
