2.35 EMERGENCY CALL E-911 (CALLER LOCATION) SUPPORT
Description
The Emergency Call E-911 (caller location) Support feature integrates the iPECS to a PBX ANI Link
unit, such as from Tone Commander, to provide caller id and location information to an emergency
center. When an emergency call is placed from a station of the iPECS, an assigned emergency CO
Line is used to connect the ANI link unit. The iPECS sends the station number, four (4) digits, to the
unit as DTMF digits. The ANI Link unit places a call to the emergency center over a connected
CAMA trunk. Caller Id and location information from the ANI Link unit database is sent to the
emergency center in the proper format and the station is connected to the call.
This feature also provides a means to identify a Power Failure signal from the ANI Link unit.
Typically, an ANI Link unit will incorporate a normally open contact that closes when power to the
unit fails. If a Power Failure signal is detected, iPECS routes emergency calls via PSTN/ISDN
circuits other than those marked for emergency call use until the Power Fail signal is removed.

Conditions
1. The system Loop Start lines connected to the ANI Link unit must be assigned to a separate CO
line group and the individual CO/IP lines assigned for emergency service.
2. The ANI Link unit must be properly connected to an SLT port and an LGCM port on the same
LAN as the MFIM. In addition, the ANI Link device must be co-located with the iPECS system,
in the same building.
3. The ANI Link unit must be properly installed and connected to a CAMA trunk from the telco to
send location information to the local emergency center.
4. It is the Customer’s responsibility to maintain the ANI Link unit number/location database; there
is no integration provided between the iPECS database and the ANI Link unit.
5. The system must be programmed for a three or four digit numbering plan. The system must
send four digits to the ANI unit. When a three digit plan is used, a leading ‘0’ is automatically
added to the station number.
6. During a power failure, if the ANI Link unit Power Fail contacts, normally open, are connected
to a system SLT port, the iPECS will recognize the fault and emergency calls are not sent to
the ANI Link unit. In this situation, emergency calls are sent over normal system PSTN/ISDN
circuits and the station digits are not sent.
7. SMDR output will identify any call made via the Emergency call feature, including the success
or failure of calls.
