Cuyahoga County: PSAP Assessment Wireline enhanced 9-1-1 In all North American jurisdictions, special privacy legislation permits emergency operators to obtain a 9-1-1 caller's telephone number and location information. This information is gathered by mapping the calling phone number to an address in a database. This database function is known as Automatic Location Identification (ALI). The database is generally maintained by the local telephone company, under a contract with the PSAP. Each telephone company has its own standards for the formatting of the database. Most ALI databases have a companion database known as the MSAG, Master Street Address Guide. The MSAG describes address elements including the exact spellings of street names, and street number ranges. Each telephone company has at least two redundant telephone trunk lines connecting each host office telephone switch to each PSAP. These trunks are either directly connected to the PSAPs, or are connected to a telephone company central switch that intelligently distributes calls to the PSAPs. These special switches are often known as 9-1-1 Selective Routers. The use of 9-1-1 Selective Routers is becoming increasingly more common, as it simplifies the interconnection between newer office switches and the many older PSAP systems. The effectiveness of this technology may sometimes be affected by the type of telephone infrastructure that the call is routed through. The PSAP may receive calls from the telephone company on older analog trunks, which are similar to regular telephone lines but are formatted to pass the calling party number. The PSAP may also receive calls on older-style digital trunks, which must be specially formatted to pass Automatic Number Identification (ANI) information only. Some upgraded PSAPs can receive calls in which the calling party number is already present. The location of the call is drawn from a computer routine which supports telephone company service billing, called the Charge Number Parameter. With some technologies, the PSAP trunking does not pass address information along with the call. Instead, only the calling party number is passed, and the PSAP must use the calling party number to look up the address in the ALI database. The ALI database is secured and separate from the public phone network, by design. Sometimes, on calls using land lines, the originating telephone number may not be passed to the PSAP at all, generally because the number is not in the ALI database. When this happens, the call receiver must confirm the location of the incoming call, and may have to redirect the call to another, more appropriate PSAP. ALI Failure occurs when the phone number is not passed or the phone number passed is not in the ALI database. In most jurisdictions, when ALI database lookup failure occurs, the telephone company has a legal mandate to fix the database entry. Page 48
Cuyahoga County: PSAP Assessment 11.3 Cost per Call Analysis by Individual PSAP This table represents data supplied by AT&T from monthly switch technology that counts call volumes. The data within the spreadsheet is intended to be a best possible scenario for using technology to calculate a cost per 9-1-1 call within each PSAP. The total call volumes do not represent calls incoming on the 10 digit non-emergency phone lines. Those calls are not able to be counted by AT&T. Cleveland is the only City that can capture 1-2-3-4 administrative calls; therefore, the results are skewed. Cleveland has technology available within their telephony to count those administrative calls.
