First Implementation Date: July 30, 2002 Original Date Posted: June 11, 2002
Summary:	Qwest announces the standardization of 911 trunk group options in DMS100 911 Tandem Selective routers in the SS7 environment. This will bring them into compliance with national standards to receive 911 calls from all vendor switches. The incoming 911 trunk groups at the Selective router will look for the ANI digits to selective route to the proper PSAP in the Charge number field of the IAM message. This standardizes calls where two sets of numbers can be sent to the selective routers, as in Calling Party Number (CPN) versus Billing Directory Number (BLDN), where PRI trunk groups are used at the end offices. Also, wireless calls where the Pseudo Automatic Number Identification (PANI) versus Mobile Directory Number (MDN).
Location and Timing of Deployment:	This standardization will take place in all Qwest switches and Selective Routers in the 14-state Qwest territory, July 30, 2002.
