Bridge the gap between PSTN and VoIP /VoIM networks
ESP Geo-spatial Router route 9-1-1 calls from any network
Command Control Communication Computers and Intelligence

A new-generation selective router, the ESP Geo-spatial Router bridges the gap between the conventional PSTN and the latest technology VoIP/VoIM networks. The ESP Geo-spatial Router enables accurate E9-1-1 call routing regardless of the network access used by the caller.

Convert PSTN/Cellular E9-1-1 calls to VoIP to increase flexibility and decrease costs. The ESP Platform can function as an Initial, Intermediate or Terminating ESRP as defined by NENA. Location of the caller is with the call allowing dynamic routing and immediate delivery of location. Easily integrated with systems currently deployed, the ESP Geo-spatial Router also provides a ready-made connection to new services as they become available with the accelerating deployment of VoIP/VoIM technologies.

 

ESP Geo-spatial Router delivers more for E9-1-1 call routing

The ESP Geo-spatial Router is designed to meet NENA i3 specifications, and handle the unique requirements of E9-1-1 call routing, regardless of the network origin : PSTN, cellular, or VoIPjVoIM. Features include:

Selective routing
Ensures that an E9-1-1 call is routed to the correct primary PSAP that is designated to serve the originating station location . The Selective Router supports both manual and automated ANI/ ESN table updates.

Alternate routing
In event that all trunks to a PSAP have fai led or are busy; the Selective Router supports multiple alternate routes.

Default routing
If no ANI is available or the ESP Geo-spatial Router is not capable of associating an ESN to the ANI, it will resort to a default routing which can be made specific to each incoming E9- 1-1 trunk

Abandoned call routing
The ESP Geo-spatial outer can be configured so that once an E9-1-1 call is received with a valid ANI , the call will be routed to the appropriate PSAP irrespective of the status of the incoming call.

Ring no answer
In the event that a ring no answer occurs on an outbound call, the Selective Router can re-route the E9-1-1 call.

Call failure re-routing
If an outbound leg releases a call in any other way then normal call clearing, the ESP Geo-spatial Router can re-route the E9-1 -1 call.

Forced hold trunks
On such t runks, the Selective Router will not retu rned on-hook until the outgoing leg (PSAP leg) has released the cal l.

Extensive ANI translation capabilities
Received ANI are converted internally into 10 digit ANI to allow all combination of incoming and outgoing ANI formats

Wireless call handling
pAN! can be received and used to properly route wireless calls. Alternatively a database can be dipped to obtain the pANI.

VoIP I2 call handling
v2 ESQK queries are supported to properly route VoIP calls.

Transfer transparency
Incoming E9- 1-1 trunks can be configured so that any transfer request on the outbound call leg is propagated back onto the incoming t runk.

9-1-1 test calls
Test calls are supported.

Manual transfer (7 or 10 digit)
The PSAP attendant activates Manual Transfer by manually initiating a switch-hook flash, waiting for audible dial tone, and dialing either a directory number, one of the regular * NX speed call codes, or one of the special *1X speed call codes (selective transfer)

Fixed transfer (speed dial transfer)
The PSAP attendant activates Fixed Transfer by pressing one of a larger number of programmable keys at the PSAP attendant position. When the key is pressed, the CPE sends a flash, followed by a short delay to await dial tone, followed by the *NX regular speed call code programmed for the particular key.

Selective transfer
The PSAP attendant activates Selective Transfer by pressing one of the pre-assigned Selective Transfer keys at t he PSAP attendant position. When the key is pressed, the CPE sends a flash, followed by a short delay to await dial tone, followed by the *1X special speed call code corresponding to the key ( * 11 for key 1, * 12 for key 2, etc.). This will trigger a transfer to one of the secondary PSAPs associated to the ESN of the E9-1-1 call.

Monitored transfer
When transferring a call, the audio path of the incoming E9- 1-1 call is always connected to the outgoing call leg. Once the target transfer party answers the call, a 3-way conference is created.

N-party conference
Patented conference capability built into each system port.
