CallerIdMethod
Description
This 32-bit parameter specifies the signal format to use for both FXS ports for generating Caller ID
format. Possible values are:
•
Bits 0-1 (method)—0=Bellcore (FSK), 1=DTMF, 2=ETSI, and 3 is reserved.
If
method=
0 (default), set the following bits:
•
Bit 2—Reserved.
•
Bit 3 to 8—Maximum number of digits in phone number (valid values are 1 to 20; default is 12)
•
Bit 9 to 14—Maximum number of characters in name (valid values are 1 to 20; default is 15)
•
Bit 15—If this bit is enabled (it is by default), send special character
O
(out of area) to CID device
if the phone number is unknown.
•
Bit 16—If this bit is enabled (it is by default), send special character
P
(private)
to CID device if the
phone number is restricted.
•
Bits 17 to 27—Reserved.
If
method=
1, set the following bits:
•
Bit 2—Reserved.
•
Bits 3-6—Start digit for known numbers (valid values are
12
for “A,”
13
for “B,”
14
for “C,” and
15
for “D.”)
•
Bits 7-10—End digit for known numbers (valid values are
11
for “#,”
12
for “A,”
13
for “B,”
14
for
“C,” and
15
for “D.”)
•
Bits 11—Polarity reversal before and after Caller ID signal (value of 0/1 disables/enables polarity
reversal)
•
Bits 12-16—Maximum number of digits in phone number (valid values are 1 to 20; default is 15)
•
Bits 17 to 19—Start digit for unknown or restricted numbers (valid values are
4
for “A,”
5
for “B,”
6
for “C,” and
7
for “D.”)
•
Bits 20 to 22—End digit for unknown or restricted numbers (valid values are
3
for “#,”
4
for “A,”
5
for “B,”
6
for “C,” and
7
for “D.”)
•
Bits 23 to 24—Code to send to the CID device if the number is unknown (valid values are
0
for “00,”
1
for “0000000000,” and
2
for “2.”
3
is reserved and should not be used.
•
Bits 25 to 26—Code to send to the CID device if the number is restricted (valid values are
0
for “10,”
and
1
for “1.”
2
and
3
are reserved and should not be used.
•
Bits 27 to 31—Reserved.
If
method=2
, set the following bits:
•
Bit 2—Set to 0 to have the Cisco ATA transmit data prior to ringing by using the Ring-Pulse Alerting
Signal (RP-AS); set to 1 to have the Cisco ATA transmit data after the firsr ring.
•
Bits 3-8—Maximum number of digits in a phone number (valid values are 1 to 20; default is 12).
•
Bits 9-14—Maximum number of characters in a name (valid values are 1 to 20; default is 15).
•
Bit 15—If this bit is enabled (it is enabled by default), send special character
O
(out of area) to CID
device if telephone number is unknown.
