ANI / DNIS OPTIONS
DESCRIPTION:
Provides a flexible means of setting in band digits to allow ANI (Automatic Number
Identification) and DNIS (Dialed Number Identification Service) when used in
conjunction with each other. The inband signaling string is as follows: Separator 1
(if used), DN1, Separator 2 (if used), DN2 and Separator 3 (if used). DN1 and DN2
fields must be flagged for either DNIS or ANI and the number of digits to be
expected. ANI service is supported by digital T1 E&M tie line service only. The two
digit call ID can be set as any two digits by selecting “AA” in the separator field. If
additional wink signaling is to be received the separator "CC" should be used. "CC"
allows for a wink that is not more than 400ms. Call digit strings and separators
depend on the service provider. If "NONE" is set as a separator a 700ms delay or
pause is allowed between the ANI fields. ANI is assigned on a trunk group basis.
Note:
AA = Don’t care
CC = Wink 400 ms max.
NONE = 700ms pause max. (expect no digits)
The following options may be selected for ANI / DNIS operation:
1. Separator 1
This indicates the start of an ANI type call. Valid
inputs include 0 to 9, *, # 2 digit call I.D. (0 to 9, *,#,

2. DN1

3. Number of digits

9, *,# AA) CC or NONE.
