Open Issues

Larry Vasquez opened up the meeting giving an overview on the action items from the previous meeting. The biggest action item again is the question on whether the new entrants will be ready on 9/29/97 in the State of Michigan.

The following are the results of that poll (i.e. ready on 9/29/97):

AT&T Yes (Larry Vasquez)

Ameritech Yes ( Barry Bishop)

Brooks Fiber No, will not be on Detroit MSA

GTE No, per Sam Mehta (3/25/97 letter from B. Bishop Minutes)

due to software delays, the two GTE switches, in the Detroit MSA, will be ready in the March/April 1998 timeframe

MCI Yes (Jim Joerger)

Teleport Yes, (Rick Arzadon) the 5E11 software upgrade has been

moved from 5/20/97 to 5/2/97. Therefore, in plenty of time for 9/29/97 testing.

Worldcom Yes (Scot Lewis) (3/14/97)

--- Jim Joerger raised the re-consideration order protocol for the State of Michigan. He would like to re-submit the selection list for central office selections. A third party was utilized the last time and we would not use them again. So the question is, how do we formally add C.O.'s in Illinois and Michigan?

The due date is June 30^th 1997. It was decided that Larry would take this issue back to Judy Evans and Terry Apenzeller to determine the re-consideration process.

--- Discussions came up again on how we would have GTE test after the original cutover in September. We will have to treat them like a new entrant and will be a good test bed on how to bring on a new entrant.

Rich Carter was not available to discuss how we would officially do this. However, previous discussions were to test via the Terrytown back-up system.

Other tests will be to perform company-to-company testing for LSR's. Also, making sure the switch and line translations needed to be tested too.

We will have a better handle on what needs to happen after the test team meetings next week in Chicago and when GTE folks get engaged.

--- Discussions around whether we will need to update the Michigan Public Services Commission (MPSC) as we move forward. It was determined that we will probably update them on a bi-monthly basis. We can use some of the Illinois FCC updates and adjust for Michigan. Dee Branch will be responsible for the documentation to submit.

--- Lots of discussions around the 911 PSAP's and how we will plan on testing. Nancy DeRoo outlined that we need to consider the following issues:

• When/how/what numbers do we test
• How do we test for ANI failures
• How do we handle default routing testing
• Will each vendor be able to determine surcharges
• We will need to test before and after the ALI database update
• We will have to test calls to the NXX holder
• How will call transfers between PSAP's be managed
• Trunking for vendors to 911 routing by rate center
• Etc./Etc. As you can tell lots of 911 issues to be resolved

Per Nancy, default PSAP is determined when they file and by county.

Nancy is to contact Michigan PSAP's to next months Illinois Test Team meetings in Chicago. However, there are 156 PSAP's in Michigan. The PSAP's should pick a NENA representative to attend.

--- GREAT NEWS!!!!!! Jim Joerger spoke with Dick Dowd (MCI) and he has volunteered to be the test team coordinator for Michigan. He is currently the test team coordinator for Illinois. Thanks to Jim and Dick. Big load off of everyone's mind.
