Subject:
9-1-1 Public Emergency Reporting Service (E
9-1-1) Display Screen and Service Printer Interfaces
Bell Canada announces the introduction of additional information that
is transmitted between the E 9-1-1 Automatic Location Identification (ALI)
System and terminals at the 9-1-1 Public Emergency Reporting Bureau.
This additional information allows support of E 9-1-1 capabilities to
support Local Number Portability between Ontario and Quebec, to identify
the cellular tower from which emergency calls are received, and to
identify the telephone number of the Local Service Provider responsible
for updating 9-1-1 subscriber records. This information is
transmitted between the ALI System and the emergency reporting bureau
using existing interfaces. These changes are expected to become
functional in early IVQ 2001.
E 9-1-1 Service delivers details regarding the origin of an emergency
call to the emergency bureau reporting bureau. Details such as the time
and date, calling line number, street address can be received from the
network by the terminal equipment at the emergency bureau.
Compatibility Impact:
Terminals described in Appendix 1 of the Bell Disclosure Document
BID-0013 are not expected to be impacted because the additional
information will be simply printed/displayed along with the currently
available information.
For terminals described in Appendices 2, 5 and 6, the revised message
formats need to be implemented if the user wishes to support the
additional E 9-1-1 service capabilities outlined above.
Documentation:
These interfaces were previously disclosed in Bell
Interface Document BID-0013, dated September 1996. The revised interfaces
are described in Bell Interface Document BID-0013,
dated April 2001. Bell Canada Interface documents are available in both
electronic and hard copy formats. Bell will invoice recipients $50 for
each electronic version, and $65 for each hard copy version. Previous
purchasers of BID-0013 will be invoiced $15 for the updated electronic
version and $20 for the updated hard copy version. These prices are
subject to change without notice.
