553-3001-306 Standard 10.00 January 2002
When the call is abandoned, the speech path is dropped, and the trunk is
released.
If Flexible Tones and Cadences (FTC) package 125 is equipped, it is possible
to configure a tone other than the one provided by default.
Call Abandon is configured on a per route basis.
Call Abandon is supported on 911 trunks only.
No B record is generated by CDR for an M911 abandoned call, because the
B record is package dependent and only applies to an established call with
Internal CDR.
Wireless sets are not supported at the Public Safety Answering Point (PSAP)
or Secondary Safety Answering Point (SSAP) for Call Abandon.
An MF tone receiver (QPC916 or NTAG20AA) is required.

10/20 Digit ANI on 911 Calls
The 10 Digit ANI feature changes the ANI format to include the NPA in the
ANI field. A single PSAP can handle any number of valid NPAs with the 10
digit format.
The 20 digit ANI feature addresses the problem of accurately determining the
location of a wireless calling party dialing 911. The first 10 ANI digits
provide the Calling Station Number (CSN). The CSN for a 911 call is the
Calling Party Number (CPN), if available, or the billing number if the CPN
is not available. The CPN, if available, is used to call the originator back when
a 911 call is disconnected.
The second 10 ANI digits, or Pseudo Automatic Number Identification
(PANI), provides the cell site and sector information to best define the
wireless calling party’s location. The PANI allows emergency assistance to
be sent to the correct area.
