Introductions/Overview

Larry opened up the meeting with introductions and reviewed the above

agenda.

Sarge Downey joins the team from GTE. He has been involved in the

Houston MSA testing for GTE. Welcome aboard Sarge!!

Cost Recovery Petition

Per Bob Reynolds, Ameritech is still planning on filing a cost recovery

petition with the Michigan Public Services Commission (MPSC). Ameritech

had planned on filing the petition before the end of January. However,

due to delays in cost analysis data, the date has been moved to early

February. Bob stated that Ameritech will be submitting a "file and use"

petition which will expedite proceedings.

Bob will notify Larry when the petition has been filed and when the MPSC

makes a decision. Larry will then notify everyone via this broadcast

list.

NPA Split Update

The software fix for the NPA Split problem was made available to

Lockheed Martin on January 7, 1998. The software was loaded and ready

for testing on January 9, 1998. Service Providers tested from January

12th through January 20th. The testing was successful and subsequently

loaded onto all production machines on January 21, 1998. Therefore, the

Detroit MSA is "technically" ready to support LNP. However, due to the

cost recovery petition that Ameritech is expecting to file no codes will

be loaded and LNP deployment is delayed indefinitely.

Switch Roll-out Schedule

Robin Meier is still responsible for sending out a revised switch

roll-out schedule when cost recovery is approved. This new schedule

would reflect the new dates for LNP deployment in the Detroit MSA

switches. Robin is still planning on providing everyone with a revised

roll-out schedule as soon as a new General Availability date is

established.

Action Items

Question: Will Ameritech load codes as of 01/21/98 or is Ameritech

still holding out as in Chicago?

Action: Determine Ameritech's position ASAP.

Responsible: Robin Meier

Opened: Assigned 01/12/98. Per Robin, Ameritech hopes to respond

no later than 01/16/98.

Status: Closed, per Robin, on 1/19/98. Ameritech will not be loading

any codes until Cost Recovery is approved.

Issue: Ameritech needs to update end office roll-out date for Detroit

taking in to consideration the G.A. date of 01/21/98.

Action: Determine and publish Ameritech end office roll-out schedule

for Detroit.

Responsible: Robin Meier

Opened: Assigned 01/12/98.

Status: Open - New roll-out schedule will be available once a General

Availability date has been established

Question: How does Ameritech plan on handling triggers? Assuming

Detroit goes G.A. on 01/21/98 and assuming that Ameritech,

MCI and TCG all load their codes on that date, will the

codes all be triggered upon loading? The real question

is does this mean that queries will be made on all calls

within the loaded NPA-NXX as soon as loaded?

Action: Determine whether Ameritech will be triggering all codes

open to portability from the start or waiting until the

porting of the first TN within the NPA-NXX that is open

to portability?

Responsible: Robin Meier

Opened: Assigned 01/12/98.

Status: Open
