Wireless E9-1-1 implementation

[Guest guest]

Monterey CHP has survived its initial Wireless E9-1-1 deployment. We're

the 128th California PSAP to have gained the ability to receive Phase 1/11

Wireless E9-1-1 calls. It marks the first activation of Wireless E9-1-1 in

Monterey and San Benito Counties, the second in Santa Cruz County, and

behind a few other PSAPs in Santa Clara County. But that's the entire

four-county geographic area for which we answer wireless 9-1-1 calls and

dispatch for the CHP. At this point, only Verizon Wireless is supported,

but this project was accomplished through the cooperation of Verizon,

Verizon Wireless, AT & T, Intrado, and the Monterey/Santa Cruz/San Benito

County and CHP Wireless Regional Coordinators.

Right now, my Comm Center is the only PSAP in Monterey and San Benito

counties accepting Wireless 9-1-1 calls directly. (Santa Cruz County

Consolidated Emergency Communications - affectionately known as " NetComm " -

beat us to the punch for the incorporated cities of ville, Santa Cruz

and Capitola by about 3 weeks.)

The other PSAPs have not yet requested their testing cycles with Verizon

Wireless (or any other wireless carrier). So we're still taking all the

wireless 9-1-1 calls in those two counties, but we are able to transfer

ANI/ALI data to the other PSAPs. We started testing on March 7th and

completed the deployment as of March 13th. We had a few problems in

transferring wireless E9-1-1 calls to a few of the 20-some primary PSAPs to

which we transfer wireless 9-1-1 calls all the time.... but AT & T solved

those pesky problems today. There are still a few primary PSAPs left on

our " partner " list that are not yet able to accept 10-digit ANI, and

several secondary PSAPs.

Prior to Wireless, the 9-1-1 environment (in California, anyway) was city

or county " pure. " Because we're regional in scope, AT & T has had to

struggle with developing access into the 9-1-1 system to allow data

transfer across and through disparate switches and central offices.

Three AT & T representatives, our Verizon technician (for our VESTA phone

system) and I spent close to 4 hours involved in conference calls while we

worked on troubleshooting the remaining problems today.

There are six wireless carriers in this part of the state; one down - five

more to go!
