ADMIN:

------

The need for SPOC's to work the issues offline and report status prior to the

scheduled conference call was discussed. All who participated in the conference

call agreed that this was the proper procedure to follow.

To help make progress and to best utilize your resources it is asked that:

1. If Assigned an Action, the SPOC is to work the action off line, during the

week, through their own company and report status as early as possible to

Dick Dowd via EMail.

2. Please provide your status via Email by noon on Wednesday's so that I may

have time to assemble them for presentation to the Team.

Note We do not attempt to resolve assigned Actions and Issues during the

conference call, as most of these involve work within the SPOC's company.

Conference Calls:

----------------

If at least 4 of the participating company's are represented on the call, the

Team will abide by the consensus of those present. If at least 4 company's

are not represented, no business will be transacted.

Agenda:

-------

Single Point Of Contact Meeting Issues & Actions

===============================================================================

At least 4 of the particapating company's were represented so the Issues

and Status's were reviewed.

ISSUE: * The FCC Field Test Coordination Manager has requested that each

SPOC provide one person in the Chicago area 5 days for

the duration of the FCC Field Test. This person will need

to attend a daily kickoff meeting in person and be within

15 minutes of the NPAC to respond to emergency meetings.

ACTION: Each SPOC to work through this request with his/her company and

their resources to determine if this is workable and report their

findings to Dick Dowd via Email.

RESPONSIBLES: SPOC Team

STATUS: All Trial Participants will have representatives present

in the Chicago area to support the Chicago Illinois FCC Field

Test, or on call within 15 minutes of notification for a meeting

with the exception of Ameritech and possibly SPRINT.

Action: In the spirit of Team building Dick Dowd will escalate

to Brent Struthers, ICC, and request support from Ameritech

to match the level of committment provided by the other

participating company's.

RESPONSIBLE: Dick Dowd

STATUS: 4/10 Contacted Brent Struthers, ICC, via Email and requested

his assistance to help the participating company's to dedicate

resources to the FCC Field Test as requested. All Trial

Participants will have representatives present in the Chicago

area to support the Chicago Illinois FCC Field Test, or on call

within 15 minutes of notification for a meeting

with the exception of Ameritech and possibly SPRINT.

ACTION: Each SPOC is to begin, if they have not already done so, to review

the FCC Field Test Plan, available at www.ported.com and

www.cameos.com, with their Task Force to determine which specific

test script's will be able to be performed by their company's

network topography within the Chicago MSA. (NOTE) Once this

input is obtained a matrix of test cases will be built that will

indicate each test case and which company's will be performing

which test cases. This will help to ensure that a through Field

Test is performed and also help to identify areas where some of

the participating company's can perform certain test's while others

perform other test's.

RESPONSIBLES: SPOC Team.

STATUS: Assigned 3/20.

4/10 All targeting 4/25/97.

SPRINT may not be able to meet 4/25.

ISSUE: * In preparation for the FCC Field Test, certain network items

need to be gathered and distributed to the participating company's.

ACTION: Each company is to determine what SSN will be used for CLASS

testing and which point codes will be utilized during the testing.

Each SPOC is requested to open these discussions within their own

company and report the status to Dick Dowd Via Email.

RESPONSIBLES: SPOC Team

STATUS: Assigned 3/20.

3/27 TCG / Rajeev Trika - TCG will use a 5ESS Switch

The point code is 005004160.

TCG will have 10 DNs per prefix that are available for test:

773-420-XXXX thru XXXX

847-720-XXXX thru XXXX

847-813-XXXX thru XXXX

630-274-XXXX thru XXXX

630-743-XXXX thru XXXX

815-280-XXXX thru XXXX

SSN = 251

translation type = 251

alias point code = 232003000

3/30 Ameritech / Robert Bartenstien -

T-CAPS for CNAM and LIDB will be exchanged via the Regional

STP's:

CHCGILWB01W 250-001-000

ELGNILEL01W 250-000-000

ALIAS 250-002-000

In the Chicago area, T-CAPS for CLASS and ISVM (if needed)

will be exchanged via the Local STP's:

DRFDILDF01W 250-003-000

RVDLILRD01W 250-004-000

ALIAS 250-005-000

And maybe this pair, depending on whether the CLEC decides to

link into these STP's (both pairs are in LATA 358):

BNTOILBA01W 250-021-000

LGRCILLG01W 250-022-000

ALIAS 250-023-000

The following SCP's will actually be the nodes that send the

queries to their networks, and thus these point codes will

appear as originating point codes on the messages (the STP'S

will simply MTP route the messages, whether it be the LSTP's

or the RSTP's):

(LTNP SCP's HOMED TO BNTO/LGRC LSTP's)

CHCGILFRA52 250-080-001

EDNDILDUA51 250-080-002

ALIAS 250-080-000

(LTNP SCP's HOMED TO DRFD/RVDL LSTP's)

CHCGILWBA54 250-081-001

ELGNILELA53 250-081-002

ALIAS 250-081-000

Participants should provision their networks to receive queries

from any of these SCP's, regardless of which LSTP's they are

linked to, because we may shift traffic, due to load

requirements, between SCP pairs.

SSN 251 will continue to be the CLASS application number for

SSP's.

ISVM is 249.

ISSUE: * Each Service Provider needs to define their network so

that an overall FCC Field Test Topography can be determined.

ACTION: Identify each participant's network's and trunking and

provide to Dick Dowd via Email ASAP. So that this information

can be combined and the FCC Field Test Topography can

be reviewed at the next face-to-face.

RESPONSIBLES: SPOC Team

STATUS: Assigned 4/09.

AT&T - Mitch Fuchs Emailed a copy of the AT&T network

to be used for the FCC Field Test on 4/15.

No other input was received.

ISSUE: * It was suggested that the SPOC Team assemble a Checklist of

all items that need to be addressed by each participating

company prior to the kick off of FCC Field Testing on July 24,

1997.

ACTION: Each SPOC is to initiate a Checklist of items that they feel

need to be addressed prior to July 24, 1997 and submit it

to Dick Dowd via Email. These will be shared with all

participating company's so that the SPOC's can track progress.

RESPONSIBLES: SPOC Team.

STATUS: Assigned 3/20.

4/09 The Testing Committee put together a draft project plan

listing many milestones. Dick Dowd copied the tasks to MS

Project. Ameritech then printed copies and distributed them

to those present. These tasks were then reviewed by the

Testing Committee. Dick Dowd will rework the tasks and suggest

dependencies. Once this is formulated Dick will distribute

the Project Plan to the SPOC Team for review and finalization.

Dick will distribute this project plan prior to the next

SPOC Team conference call 4/17.

4/17 Dick DOwd is working on the update and will have it

distributed prior to the next conference call.

NEW ISSUES AS OF 4/17/97:

ISSUE: How will participants be able to transport ISUP messages across

the network for the FCC Field Test?

ACTION: Each SPOC to determine whether they will be wanting to

test ISUP messaging during the Field Test.

RESPONSIBLES: SPOC Team

STATUS: Assigned 4/17

=======================================================================

ISSUES: * Test Script Prioritization, Overall Test Time Line & Porting

partners are all valid issues that will need to be addressed

but they are dependant upon Action's above.

Thanks,
