SUBJECT: IIN Testing Using Predictor System
DATE: November 7, 1988
FILE: WT88-26-03 (Revised)
PROCEDURE FOR: DSOC Personnal
INFORMATION FOR: I&M Field Personnel
AUTHOR: Donald Aber, (414) 678-6866
This letter replaces WT88-26-03 dated February 2, 1988.
Our DMS, #5ESS and Siemens central offices can provide a Centrex service
that the rest of our central offices can't offer, called Integrated
Information Network or IIN.
This service allows the use of a new type of telephone called a Meridian
Business Set (MBS). However, the MBS can only be used in a DMS type
office. What's unique about the MBS is a special "line card" (LEN) in the
central office associated to the MBS's Primary Directory Number (PDN).
The "line card" allows 56 separate telephone numbers to be assigned to a
single cable pair.
Other services and features are explained in the following UPDATE letters:
WT87-26-05 Integrated Information Network (IIN) Service
WT87-26-05A, B, C... IIN Customer Profiles
WT87-26-06 IIN Centrai Office Features - DMS 100
WT87-26-07 IIN Central Office Features - 5ESS
WT88-26-01 CRSAB Repair Answer for IIN Service
WT88-26-02 IIN Business Set Trouble Shooting Procedures
IIN service with Meridian Business Sets are not MLT testable. Predictor is
the vehicle that must be used when testing under these conditions.
Attached you'll find flow charts, sign-on and sign-off procedures, testing
sequences and explanations to testing IIN MBS lines.
This letter will be revised as new tests and procedures are developed and
added as new attachments.

PREDICTOR SYSTEM
FOR TESTING
MERIDIAN BUSINESS SETS
BASIC MBS TROUBLE REPORT FLOW
MBA/CRSAB
To assist the DSOC in analyzing the customer's trouble report, the
Repair Service Attendant (RSA) should ask our customer the following
questions:
1. Primary Directory Number on Key 1.
2. Location of the Business Set.
a. Floor
b. Room
C. Desk
3. Complete description of the problem.
a. Time problem occurred.
b. What number(s) was the customer talking to and who called
who.
c. Does the problem occur all the time or at times.
d. Does the problem occur while using a feature.
e. Etc.
4. Handle Code - MBA.
5. Contact name and number.
6. Time received and commitment.
7. Send to OSOC.
NOTE - When received, make sure that the report is not involved
with a cable trouble or service order activity.
SIGN-ON/OFF PROCEDURE
PREDICTOR/DMS
MBS are unique in that you can't test them with LMOS. MBS will test
as a short or open depending on the customer's equipment that is
associated with the MBS. MBS troubles must be tested using
Predictor. The following is the sign-on procedure to be used to
verify and test MBS lines.
AT&T 6500 Sign-On -
1. Obtain session that contains Predictor (usually D)
2. Depress Command Key
3. Cursor to CH (Change Host)
4. Depress Enter Key
5. Cursor to ASYNC MODEM
6. Depress Enter Key
7. Check CAPS LOCK (will use lowercase)
8. Depress PF3 for Modem/Dial
9. Depress PFZ for Select
10. Enter Predictor number
11. Depress PF1
12. Enter login: ver (lowercase)
13. Enter Password: VER (uppercase)
14. Enter Terminal VT100
15. Response will be $
At this point, you are now signed on to Predictor.
16. Enter Query
17. Enter Switch I.D. (Wire Center's lowest NXX)
18. Response will be a ?
19. Enter login
20. Enter User Name: LOCTST
21. Enter Password: LOCTST
At this point, you are now signed-on to the DMS switch.
22. Verify Directory Number
(QDN) and LEN (QLEN)
AT&T 6500 Sign-Off
Any time you are not using Predictor to verify a DMS line, you must sign-off
from the switch and also Predictor. This will free up the customer's line and
also free up the ports to Predictor and the switch as there are a limited
number of ports.
SIGN-ON/OFF AND REQUEST PROCEDURES
MAINTENANCE ADMINISTRATIVE POSITION COMMAND INTERROGATOR
(MAPCI)
MBS will only work in a DMS type office. Since MLT cannot be used to properly
test MBS, Predictor is your only vehicle for testing. To test MBS with
Predictor, you must gain access to the various "maintenance levels" In the
DMS switch. The Maintenance Level Flow Chart is on Attachment 3A.
There are various methods of signing on to the Maintenance Levels and they are
as follows:
Method 1 Method 2 Method 3
-------- -------- --------
Enter MAPCI Enter (Future)
Response MAPCI: MAPCI; MTC; LNS; LTP;
Enter MTC Response
Response MTC: MAPCI; MTC; LNS; LTP;
Enter LNS MAPCI:
Response LNS: MTC:
Enter LTP LNS:
Response LTP: LTP:
Once access is gained to the DMS switch by any of the methods listed above,
you now have access to various tests located within the levels you sign-on to.
There are 5 tests that must be performed on all trouble reports. These tests
are addressed on Attachments 4 through 8.
MAINTENANCE ADMINISTRATIVE POSITION COMMAND INTERROGATOR
MAPCI
Testing Levels:
MTC = Maintenance
LNS = Lines
LTP = Line Test Position
LTP MAN = Line Test Position Manual
LTPLTA = Line Test Position Line Test Access
Additional tests will be added as procedures are developed.
MAPCI TEST SEQUENCE PROCEDURE
To properly analyze and test MBS trouble reports, Attachments 4
through 8 must be followed In proper sequence. Any deviation c6uld
result in improper analysis and tests and possibly an irate customer.
To begin the testing sequence, you should have a printed copy of the
Primary Directory Number (PDN) by using the Query Directory Number
(QDN) command and a copy of the LEN information by using the Query
Line Equipment Number (QLEN) command.
In other words, this is a comparison between what's programmed in the
switch and what's in the field.
