3. Programming
STEP 1: Assign the Basic Data for ISDN. (Refer to Chapter 3, “Basic Data Assignment for ISDN”.)
Note:Pooled modems and modems connected to analog stations may be used on PRI channels when a straight
digital data connection is not required. With PRI, modem pooling will always be automatic when
accessing a PRI channel by setting the “AMND” command (Parameter A/D) to 0. If “AMND” (Parameter
A/D) is set to 1, the channel will either use modem pooling or a straight digital path depending on the
number dialed. This number is compared with the PRI link to the other end switch to determine if an
analog or digital extension is being called.

DATA UNIFORM NUMBERING PLAN-PRI
D-122 DATA UNIFORM NUMBERING PLAN-PRI
1. General Description
This feature enables data stations to be assigned a set of UNIFORM NUMBERS to distinguish data extensions
from voice extensions.
2. Operating Procedure
Originating a Data Adapter call using uniform numbering:
1. Dial the private line access code (Usually “8”).
2. Dial the Interoffice number (location code uniform number) and the desired DTE number; RDX (Interoffice
number)-XXXX (Desired DTE number).
3. When the called DTE answers, data communication can begin.
Originating a Data Adapter call using Inter-office coordinate numbering plan:
1. Dial the Interoffice number (location code uniform number).
2. Dial2 the desired DTE number.
3. When the called DTE answers, data communication can begin.

DIRECT-IN TERMINATION (DIT)-PRI
D-137 DIRECT-IN TERMINATION (DIT)-PRI
1. General Description
This feature automatically routes incoming network exchange calls from an ISDN network and Public/Private
Telecommunication network directly to a preselected station without Attendant assistance. The call can then be
processed by the called party. THREE-WAY CALLING [T-2], CALL TRANSFER [C-10], etc., are handled in
the same manner as any normal trunk call.
2. Operation Procedure
The calling party, outside the system, dials the telephone number as usual. However, the call is answered directly
at a predetermined station, bypassing the ATTENDANT CONSOLE [A-3].
3. Programming
STEP 1: Assign the Basic Data for ISDN. (Refer to Chapter 3, “Basic Data Assignment for ISDN”.)
STEP 2: ASYD - System Data 1, Index 147 :  DIT supervisory timer for a busy station.
Note:This index works when System Data 2, Index 11, bit 7=1.
System Data 2,Index 11,bit 7:Will the DIT call to a busy station be routed to ATT or queue
to the busy station?
0/1=ATT/Queue
Note:If the call goes to ATT, it will ring in on the BUSY
or ICPT key.
STEP 3: ARSC - The DIT target station receiving the call must be assigned a Route Restriction Class (RSC),
allowing the station to be connected to the trunk. The DIT route must be allowed via Route
Restriction Indexes (RRI) 0 & 1.
STEP 4: ACFR - Designate the type of incoming Call Class Indexes (CCI) which require a Transfer Service
Feature Index (TSFI) = 3, DIRECT-IN TERMINATION. The type of CCI must match
CDN 6 of the DIT route. For Night DIT (NIGHT CONNECTION-FIXED [N-1]), allow the
CCI a TSFI = 2, NIGHT CONNECTION-FIXED [N-1].
For Day and Night DIT Service-Same Station
STEP 5: ACSI - Assign the Route Number, Trunk Number, and Connection Service Index = 3 for DIT. Then
assign the Tenant Number and Station Number to serve as the DIT station. 
For Day DIT Service 
STEP 6: ACSA - Assign the Route Number, Trunk Number, Connection Service Index A = 2 for DIT. Then
assign the Tenant Number and Station Number to serve as the DIT station.

STEP 7: ACSA - Assign the Route Number, Trunk Number, Connection Service Index A = 2 for DIT. Then
assign the Tenant Number and Station Number to serve as the DIT station. 
ACSI - Assign the Route Number, Trunk Number, Connection Service Index = 4 for NIGHT
CONNECTION-FIXED (DIT) [N-1]. Then assign the Tenant Number and Station
Number to serve as the DIT station.
Night DIT Only
STEP 8: ACSI - Assign the Route Number, Trunk Number, Connection Service Index = 4 for NIGHT
CONNECTION-FIXED (DIT) [N-1]. Then assign the Tenant Number and Station Number
to serve as the DIT station.

FLEXIBLE NUMBERING OF STATIONS-PRI
F-21 FLEXIBLE NUMBERING OF STATIONS-PRI
1. General Description
This feature provides the ability to assign voice station numbers and data station numbers, to any corresponding
instrument location depending solely upon numbering plan limitations.
2. Operating Procedure
No manual operation is required.
3. Programming
STEP 1: ASYD - System Data 1, Index 16: Enable one- to five-digit station numbering for the
system. Assign 3FH.
Index 92, bit 3: Must be assigned as data “1”.
STEP 2: ANPD - Reserve an access code for station numbering. Only the stations with the NND assigned
here will appear on the BLF.
STEP 3: ASPA - Assign the station numbering in such a way that the system will differentiate the station
numbering via the access codes programmed here. For the example shown, the following
data is programmed:
STEP 4: ASDT - Assign the station number.For station 31; For station 321; For station 322;
TN: 1TN: 1TN: 1
ACC: 31 ACC: 321 ACC: 322
CI: N, H. CI: N, H. CI: N, H.

FAULTY TRUNK REPORT-PRI
F-26 FAULTY TRUNK REPORT-PRI
1. General Description
This feature allows a station to report a noisy or faulty ISDN trunk number by dialing a special access code
before hanging up. The FAULTY TRUNK REPORT consists of Trunk number, Station number, associated
Time Division Switch and reported time. This information is displayed at the MAINTENANCE
ADMINISTRATION TERMINAL [M-18] and/or fault printer.
2. Operating Procedure
To enter a FAULTY TRUNK REPORT:
1. Switchhook flash before disconnecting; receive Special Dial Tone.
2. Dial the FAULTY TRUNK REPORT access code; receive Service Set Tone.
3. The MAT [M-18] records the FAULTY TRUNK REPORT and returns the line to the original connection.
3. Programming
STEP 1: ANPD - Reserve a number level for feature access code.
CI=H, NND=Number of digits for an access code.
STEP 2: ASPA - Assign an access code.
CI=H, SRV=SSC, SID=46 (FAULTY TRUNK REPORT)
STEP 3: ASFC - Allow this service restriction. SFI46=1
