> 911 Regional Planning

The BVCOG 9-1-1 program oversees the planning, implementation, upgrades and financial responsibilities of 9-1-1 service and county database maintenance projects. The 9-1-1 service includes all the network, database, and equipment necessary for the proper routing of 9-1-1 calls – both landline and wireless. We also serve as an integral resource for the county addressing, database maintenance and mapping services. (See Regional GIS section below.)

Whom We Serve
The regional 9-1-1 plan includes six Public Safety Answering Points (PSAPs) in Burleson, Grimes, Leon, Madison, Robertson and Washington counties. (Brazos County has a 9-1-1 District so they are not included in the regional plan.) The PSAPs are responsible for answering all the 9-1-1 calls that originate from a defined geographic area. Annually, these six PSAPs have answered more than 91,300 9-1-1 calls and more than 62% of them originated from a wireless phone.

The 9-1-1 systems and database maintenance projects are funded by a local service fee of $.50 cents per local exchange access line per month, and by an equalization surcharge fee imposed on intrastate long distance service. Both activities are subject to the guidelines and policies of the Commission on State Emergency Communication (CSEC) and funding availability as appropriated by the legislature. More information can be found on CSEC’s web site at www.csec.texas.gov.

9-1-1 Call Flow
When a 9-1-1 call is placed from a landline phone it first goes to the local telephone Central (or Exchange) Office. The Central Office (CO) recognizes it as a 9-1-1 call and sends the call on a dedicated 9-1-1 network to a larger CO that has selective routing capabilities. Network from all the CO’s are concentrated at the Selective Router and based on a unique number called an Emergency Service Number (ESN) given to every address, the call is routed on dedicated network to the proper PSAP. The 9-1-1 calltaker at the PSAP receives the call on the 9-1-1 equipment and can either transfer the caller to the proper responding agency or dispatch the responding agency via a radio or paging system. The 9-1-1 caller’s name, address and ESN are displayed on the 9-1-1 equipment when called from a landline phone.

Wireless 9-1-1 Call
The wireless system consists of over 200 towers that route through the 9-1-1 network. Each tower is addressed and delivers the tower address and callback number with each call. We currently do not receive the geographic (physical) location of the 9-1-1 caller, however, we plan to begin implementation of Wireless Phase II by mid-2007. The number of 9-1-1 calls received from wireless callers continue to increase. From September 2005 to August 2006, the regional PSAPs received a little over 56,600 calls from a wireless phone.
