Explanation
The E911 subsystem generates log report E911202.
Log E911202 alerts operating company personnel of the following conditions:
The system can route the call by default when the subsystem generates this log.
For wireline E911 calls, this log displays the ANI DIGITS field as ANI DIGITS =. For wireless E911 calls, this log displays the ANI DIGITS field as PANI DIGITS =.
Format
The log report format for E911202 is as follows:
E911202 mmmdd hh:mm:ss ssdd INFO ANI TROUBLE ON E911 TRUNK CKT <trunk name> <trunk member number> <28 character text message> <digit description> = <digits>
Example
An example of log report E911202 follows:

Field Descriptions
The following table describes each field in the log report:
-----------------------------------------------------------------------------------------
Field Value Description
-----------------------------------------------------------------------------------------
INFO ANI TROUBLE Constant Identifies the possible ANI entry problem or
CALL DEFAULT ROUTED trunk fault.
-----------------------------------------------------------------------------------------
CKT Character String Identifies the E911 trunk Common Language
Location Identifier (CLLI) and unit number.
-----------------------------------------------------------------------------------------
ANI or PANI Variable The ANI indicates a wireline call or a
(up to 4 characters) wireless call that did not expect PANI.
Digits will be the ANI digits. The PANI
indicates a wireless call. Digits will be the
PANI digits.
-----------------------------------------------------------------------------------------
ANI DIGITS Up to 15 Digits Indicates ANI digits or unexpected calling
digits that the trunks receive.
-----------------------------------------------------------------------------------------
TEXT MESSAGE Variable Indicates one of the following values with
(up to 28 characters) their associated descriptions:
CALL DEFAULT ROUTED Indicates the call was routed, based on the
default Emergency Service Number (ESN) assigned
to the trunk in table TRKGRP.
CALL ROUTED ON CALLED Indicates the call experienced ANI or PANI
DIGITS failure. The call will still route, based on
the called digits. This message occurs only
when the called digits are not 911, 11, or 1.
PANI NOT EXPECTED: Indicates a wireless E911 call incoming on an
DFLT RTE E911 MF trunk. Field EXTSIG = "Y".
The ANI of the callback number ends with a start
mark other than ST. No PANI will be sent.
The DMS system default routes the call, using the
ESN from table TRKGRP.
NO CALLING PARTY NUMBER Indicates a wireline E911 call incoming on an
PARM Integrated Services Digital Network User Part
(ISUP) trunk. The E911 option is assigned.
Subfield E911SIG = E911_STD has no calling party
number parameter. The system will attempt to use
the charge number parameter. If the charge number
is missing or invalid, the subsystem will generate
another 202 log indicating "CALL DEFAULT ROUTED."
NO DIGITS IN CALLING Indicates a wireline E911 call incoming on an ISUP
NUMBER trunk. The E911 option is assigned.
Subfield E911SIG = E911_STD has no digits in the
calling party number parameter. The system will
attempt to use the charge number parameter. If the
charge number is missing or invalid, the subsystem
will generate another 202 log indicating "CALL
DEFAULT ROUTED."
INVALID DIGS IN CALLING Indicates a wireline E911 call incoming on an ISUP
NUMBER trunk. The E911 option is assigned.
Subfield E911SIG = E911_STD has invalid digits in
the calling party number parameter. The "ANI
DIGITS" field will display the digits. The system
will attempt to use the charge number parameter.
If the charge number is missing or invalid, the
subsystem will generate another 202 log indicating
"CALL DEFAULT ROUTED."
NO CHARGE NUMBER PARM Indicates a wireline E911 call incoming on an ISUP
trunk. The E911 option is assigned.
Subfield E911SIG = E911_CHG has no charge number
parameter. The system will attempt to use the
calling party number parameter. If the calling
party number is missing or invalid, the subsystem
will generate another 202 log indicating "CALL
DEFAULT ROUTED."
NO DIGITS IN CHARGE Indicates a wireline E911 call incoming on an
NUMBER ISUP trunk. The E911 option is assigned.
Subfield E911SIG = E911_CHG has no digits in the
charge number parameter. The system will attempt
to use the calling party number parameter. If the
calling party number is missing or invalid, the
subsystem will generate another 202 log indicating
"CALL DEFAULT ROUTED."
INVALID DIGS IN CHARGE Indicates a wireline E911 call incoming on an ISUP
NUMBER trunk. The E911 option is assigned.
Subfield E911SIG = E911_CHG has invalid digits in
the charge number parameter. The ANI DIGITS field
will display the digits. The system will attempt
to use the calling party number parameter. If the
calling party number is missing or invalid, the
subsystem will generate another 202 log indicating
"CALL DEFAULT ROUTED."
