Businesses, shared tenant services, college campuses, and other institutions are
sometimes distributed geographically among several locations or dispersed over a large
area with their telephone extensions linked to a single Private Branch Exchange (PBX)
switch. In such a geographic environment, telephone extensions are often not in the same
physical location as the PBX. They may be located on different floors, buildings or
campuses.
Most telephone systems are configured such that only the main PBX Telephone Number
and its location information are sent to emergency services when 911 is dialed.
Consequently, the exact physical location of the emergency must be determined by
questioning the caller. When the caller does not know or cannot respond, critical time is
spent searching for the person in distress when emergency services arrive on the scene.
The Teo E911 Response Server 9145 resolves these issues. The 9145 contains a station
data table that has an exact location description for each PBX station set. Every time any
PBX phone is used to dial 911, the 9145 ensures that the correct ANI (Automatic Number
Identification) is sent to the PSAP 911 Call Taker and then it instantly sends a text message
alert to every need-to-know person you want notified about the emergency event. In a true
emergency every second counts; your safety staff members, security team, key
management personnel, and anyone else instrumental in your Emergency Procedures Plan
will be appropriately notified well before the public Emergency Responders arrive. The
E911 Response Server 9145 provides audio recording and real-time audio monitoring.
Prank 911 call activity will be instantly identified and you will have the opportunity to take
corrective action seconds after the prank call is originated. This is also a valuable tool for
validating when an abandoned 911 call has occurred.

The E911 Response Server 9145 is designed for long term reliability and nonstop service,
even if hardware maintenance is ever required. The system is designed with redundant
hot-swappable power supplies and redundant hot-swappable drives that may be replaced
while the system remains in a fully operational mode.
The Emergency alert notifications include PC pop-up screen views with both text and
graphic presentation containing calling party information, location information, who’s been
notified, direction and map information, as well as emergency response procedure
documentation, all customizable. Alerts about emergency calls will generate audible
attention-getting sound and all recipients will get detailed text and supporting information.
The alerting devices can be PC screens, cell phones, pagers, or even alerts via email
messaging. Everyone who needs to know will be alerted.

The 9145 monitors calls that originate from the PBX towards the Telco network. When a
911 call is detected, the 9145 changes or passes through the 911 network-bound callers
telephone number (ANI) according to a user programmed database (station table).
The PBX must be programmed to route 911 calls to the ISDN-PRI port that is connected to
the 9145. Once a caller using the PBX goes off hook and dials 911, the calling party's 3- to
10-digit station number is sent to the 9145 via the ISDN-PRI Data Channel (D Channel). This
number is then used as the input to the internal station table database to retrieve the
translated 10-digit ANI for the caller's station.
The 10-digit translated ANI is forwarded via the Telco ISDN-PRI D channel toward the 911
network. The ANI is sent to the 911 Call Taker and the Automatic Location Information (ALI)
is retrieved from the Telco ALI database using the received ANI. Upon answer of the 911
call, the voice connection is then completed between the PBX caller and the 911 Call Taker.
The 9145 generates a call start record at the time it receives the 911 call from the ISDN-PRI
connection. The call start record is recorded in the system's Log file and, if programmed to
do so, the system will report the event to PC Popup Displays and other reporting devices.
When the 911 call ends, the 9145 will generate a call disconnect record that is also logged
and reported. The call disconnect record is sent to the reporting devices.
The 9145 also has the ability to “mask” the outgoing caller ID on non-911 calls. If call
masking is enabled, the caller ID sent for non-911
or pilot number. Sensitive areas such as school classrooms may want a pilot number or
administration number presented as the caller ID for non-911 calls.
