of the appropriate E911 tandem, 911 call routing, default routing for ANI failures, and assignment of
geographically valid pANI numbers from the wireless carrier’s number range. The E911 customers must
agree on which PSAP will accept 911 calls from the various cell sites including when ANI failures occur.
Wireless Carriers should also determine if the E911 Customers wish to segregate wireless 911 calls from
wireline 911 calls by implementing separate trunk groups to the PSAP. All premises based E911 databases
should be identified as well as any special procedures necessary to update those databases.
Carriers must also work directly with Intrado to include the Carrier’s pANI numbers in the appropriate
Security Tables and to identify the appropriate E2 interface to invoke for Phase 2.
A Service Inquiry must be initiated by the Wireless Carrier through the BST Account team for the Type
2C trunk connections and/or SS7 /ISUP trunks to the E911 tandems. If SS7 connectivity will be used,
refer to Appendix A of this guide. The BST Wireless E911 Implementation Manager will discuss with
the Wireless Carrier the process of ordering / provisioning the digital data circuits to the ALI computers,
if new circuits are required.
The Wireless Carrier must contact Intrado, the BST E911 database vendor, for all database related steps
necessary for the establishment and maintenance of wireless database records and interfaces to the ALI
computers. Carriers must post valid records in the E911 database prior to testing or turning up service.
Additional information related to database requirements is found in this guide.
Since access to E911 is a critical issue in today’s environment, it is necessary for the Wireless
Carrier to provide 24 X 7 contact name and telephone number information for maintenance and
trouble handling / clearing.

Coordination Process: BST Wireless Account Team
The BST Wireless Account team will receive the initial request from the Wireless Carrier and initiate the
BST Service Inquiry process for interconnection to the BST E911 network. The BST Account team will
contact the BST Wireless E911 Implementation Manager to begin the internal BST coordination process.
Various BST departments will review the Service Inquiry and update with additional required information.
The BST Account team will then complete form RF-1004WS and forward this form, along with a copy
of the Service Request, to the BST Wireless Service Center where service orders will be input into the
service order system.
A copy of the form RF-1004WS will also be distributed to the BST Implementation team and Intrado.
2.4
Coordination Process: BST Wireless E911 Implementation Manager
The BST Wireless E911 Implementation Manager will assist the Wireless Carrier with the requirements
for connecting to the BST E911 network. During this process the BST Wireless E911 Implementation
Manager will determine if it is necessary for the Wireless Carrier to order digital data circuits to the
BST ALI computers. The technical solution chosen by the Wireless Carrier will determine the need
for these data circuits:
