Michigan Number Portability Implementation Meeting Minutes

Meeting Held In Chicago, Illinois

September 8, 1997

Meeting Minutes taken by Larry Vasquez, AT&T.

• Attended via Bridge

Agenda:

Larry opened up the meeting by introducing Mick Koutz, GTE, to the team. Mick will be the GTE Implementation member going forward. Mick Supports Michigan, Ohio and Pennsylvania. We welcome Mick to the team.

Larry also indicated that through several e-mails that had gone out, a new testing date has been established for Detroit. The new target date is 10/1/97. Dick did mention that MCI is porting a number "in" from Ameritech starting today. Therefore, we are officially meeting the testing start date for Detroit.

A couple of LSPs were down for part of last week

Additional time still required to complete tests Sprint (1/2 way completed)

TCG (still need to test)

New porting to a different company will begin this week

Have not uncovered any major problems

Major portions of testing still on 10/1

Due date on orders due 9/15 by issuing LSR’s

OC asked if it was too late for AT&T to start IXC testing for Detroit??

OC indicated that we would probably do an Oak Brook to Detroit test. Dick stated that AT&T would have to coordinate our testing activities with Hamp from MCI ( only number that can be ported for now).

OC stated that he would check on what tests and to what extent AT&T would plan on testing. Also, send a list of telephone numbers to the appropriate parties.

We want to minimize the confusion to PSAPs

can AT&T do their 911 testing at the same time as TCG, Ameritech, MCI??

AT&T has to port as soon as possible if we are to keep on schedule Larry and OC to follow up and advise on weekly conference calls.

Status on whether a solution has been reached for the call transfer problem from a PSAP.

The problem has been fixed in the Lucent 5ESS and is only a problem with ported numbers...- REL - NA008 has the fix but no General Availability (GA) date has been announced per Joe Lichter.

Still not sure whether TCG has U&M capabilities. Nancy stated that Rajeev and Art Brett were looking into. The U&M capabilities are part of the 911 testing activities. This has to be completed.

Jim Joerger stated that in the Michigan timeline, only the initial 20 Ameritech offices are listed. Barry stated that that was not correct. He had already updated the timeline and it is up to date. It includes the new Detroit MSA offices that were added during the last go around of pick lists.

Jim agreed and recommended that at the next Detroit meeting we go through the timeline to determine if any outstanding tasks need to be addressed and/or updated with new dates.

All of us agreed that this would be a good idea. As an example, the TCG portability date shows January 1998 on the timeline. For now Sharon will check on the date, but we will all need to got through the timeline and be prepared to update any dates as appropriate.
