TRUNK DATA 
1. Trunk Group Data Block (Table 9-1) 
1.01 The Trunk Group Data Block (DTGP Pro- 
gram) defines the parameters for each of the 16 
possible trunk groups in the system. A Data Block 
must be completed for each trunk group in the 
system. Not all of the prompts listed below are used 
for all trunk types. The response given to the TKT 
(trunk type) prompt will determine which prompts 
will be given. Table g-la shows the prompts that 
can be expected for each trunk type. (Use the 
proper system record form for the type of trunk 
being defined.) Data is entered as follows: 
REQ (Request)--Indicates that the program has 
loaded. Three responses are possible: 
NEW-To create a new trunk group. 
CHG-To alter an existing Data Block. 
OUT-To delete an existing Data Block. 
NOTES: 
1. Before the OUT command is accepted, all 
trunks must be deleted from the group by 
using the DTRK Program. 
2. If OUT is entered, only the Trunk Group 
Number (GRP) needs to be entered. No 
other entries are necessary. 
GRP (Trunk Group Number)-Identifies the trunk 
group number. Sixteen groups are available (00 
- 15). If private lines are to be used, they all 
occupy one trunk group called PVL. The PVL 
group replaces group 15. 
Enter: 00 - 15 (Trunk Group Number) or PVL. 
TEN (Tenant Number)-Identifies the tenant to 
which the trunk group belongs. 
Enter: 0 or 1 (Tenant Number). 
TKT (Trunk Type)-Identifies the type of trunk to 
be used in the group. 
Enter: COT-Local CO trunk. 
FEX-Foreign Exchange line. 
DID-Direct Inward Dialing trunk. 
CSA-CCSA line. 
PROGRAMMING PROCEDURES 
SECTION 200-255-309

TIE-TIE trunk. 
WAT-WATS line. 
NOTES: 
1. 
2. It is not possible to enter a change (CHG) 
for Trunk Type (TKT). The Data Block 
must be deleted (OUT) and a new (NEW) 
Data Block must be entered. 
The ‘DNIS” prompt will appear only when 
one of these trunk types (DID, CCSA, TIE) 
is entered. 
DNIS (DNIS Allowed?)-Defines if Dialed Num- 
ber lndentification Service (DNIS) is allowed. 
This prompt will appear only when TKT is DID, 
CCSA, or TIE. 
Enter: Y or N. 
NOTE: 
DNIS is not intended to tie two PBXs together. 
Each PBX DN needs to be in a table, limiting 
it to 125 stations. However, the most impor- 
tant thing to remember is that a station user is 
NOT able to dial a trunk. 
DIG (DNIS Digits Received)-Defines the num- 
ber of digits that will be received from an incom- 
ing dialed number on a DID, CCSA, or TIE trunk. 
Enter: 1 - 5 digits. 
NOTE: 
If DNIS is currently programmed at N, and 
then at a later date changed to Y, the default 
value of DIG will become zero (0). 
IA0 (Incoming/Outgoing)-Determines whether 
the trunks will give 2-way or 1 -way service. 
Enter: ICT-Incoming only. 
OGT-Outgoing only. 
IAO-2-way. 
STP (Advance Step)--Identifies the next trunk 
group in a route advance sequence. If a station 
user attempts to access a trunk in this group and 
all trunks are busy, then a trunk from the group 
identified in response to STP will be selected. 
Enter: 00 - 15 (Next Trunk Group Number) or 
NONE. 
9-1

SECTION 200-255-309 
FEBRUARY1992 
COD (Access 
Code)-Defines the access code 
for the trunk group. Access codes can consist of 
1, 2, or 3 digits as long as there is no conflict in 
the system. For example: 3 cannot be used if 30 
or 300 is used as an access code or DN. 
Enter: 1 - 3 digits. 
COS 
(Class of Service)-Defines the feature access 
level of each inward dialing trunk (TIE, DID, or CCSA 
trunk). Use one of the 16 Classes of Service that has 
been defined via the DCOS 
Program. 
Enter: 0 - 15 (COS number). 
TRN (Transmission)-Defines the transmission 
arrangement that is required for the trunks in the 
group. The entry made here will determine the 
type of PAD switching that is performed on trunk 
connections (see Table g-lb for loss plan). 
Enter: NTC-Non-transmission compensated 
(2-wire circuit with less than 2dB loss). 
TRC-Transmission compensated (4- 
wire circuit or 2-wire circuit with greater 
than 2dB loss). 
VNL-Via net loss (4-wire VNL circuit). 
STR (Start Arrangement)--Defines the start ar- 
rangement that is to be used by the trunks in the 
group. 
Enter: IMM-Immediate start. 
WNK-Wink start. 
DDL-Delay dial. 
WTA (Warning Tone Allowed?)-Defines an in- 
terruption-protected trunk group (e.g., a data 
line). An “N” response will prevent warning tones 
from being applied to this trunk group. 
Enter: Y or N. 
OAB (Outgoing Absorb Digits)-Identifies the 
digits which are to be ignored by the Toll Restric- 
tion program. These digits will be outpulsed, but 
will not be counted as the first digit. 
Enter: Digits to be absorbed (for example: 1; 
maximum: 2 digits) or NONE. 
IAB (Incoming Absorb Digits)-Defines the 
number of digits that are to be stripped from an 
incoming dialed number from a TIE, CCSA, or 
DID trunk. Enter: Number of digits (maximum: 2) or NONE. 
TRNl (Translated Number l)-Defines the ab- 
sorbed digit (IAB) that is to be translated from 
one digit to another digit or digits (see example 
following TRN2). . 
Enter: X # Y, X # YY, or NONE. 
(X = The digit that is to be translated. 
When two digits are absorbed, only the 
second digit will be translated. 
Y or YY = The translated digit (Y) or 
digits (YY) that will be inserted.) 
TRNP (Translated Number 2)-Defines the digit 
that is to be translated from one digit to another 
digit or digits. (The same as TRNl; used when 
over 100 digits are to be translated-see ex- 
amples.) 
Enter: X # Y, X # YY, or NONE.

TOL (Toll Restriction Class)-Assigns one of the 
IO classes of Toil Restriction to each outgoing 
TIE, CCSA, and DID trunk. Classes 0 - 7 are 
defined in the Toll Restriction Data Block (DTOL 
Program). Class 8 is simple Toll Restriction and 
restricts when either 1 or n is dialed as the first 
digit. NONE defines the trunk as unrestricted. 
Enter: 0 - 8 or NONE. 
FLT (Flash-hook Timing)-Defines the length of 
time of a flash-hook (line open) while connected 
to a CO trunk. On an electronic/digital telephone, 
the flash-hook will occur whenever them key 
is pressed. 
Enter: 1 = 500 milliseconds. 
2 = 1 second. 
CTX (Centrex)-A “Y” response indicates that the 
trunk group is operating on Centrex lines. An “N” 
response indicates that the trunk group is not 
operating on Centrex lines. The entry “Y” made 
here defeats Toll Restriction. 
Enter: Y or N. 
NOTE: 
When DNIS = Y, the following prompts do 
NOT apply, eventhough they appear on the 
screen: COS, IAB, TRNI, TRN2, and TOL.

3. Trunk Data Block (Table 9-3) 
3.01 The Trunk Data Block (DTRK Program) de- 
fines the parameters for each of the trunk circuits in 
the system. A separate Data Block must be com- 
pleted for each trunk circuit in the system. 
NOTE: 
When using the NDTU PC6 (Digital T-l inter- 
face) Trunk Data Block programming remains 
the same. Each T-l channel (24 per each 
NDTU PCB) equals a trunk circuit. 
3.02 The trunk type (TKT) defined for the group (in 
the DTPG Program) will determine which entries 
must be made. Not all prompts are meaningful for 
all trunk types. Table 9-3a shows the prompts to 
which responses should be made. (Use the proper 
system record form for the type of trunk being 
defined.) Data is entered as follows: 
REQ (Request)-Indicates that the program has 
loaded. Three responses are possible: 
NEW-To create a new Data Block. 
CHG-To alter an existing Data Block. 
OUT-To delete an existing Data Block. 
NOTE: 
If OUT is entered, then only the port (POR) 
needs to be specified. No other dafa entries 
are necessary. 
POR (Port Number)--Identifies the hardware lo- 
cation of the trunk circuit that is to be defined in 
a PERCEPTION, or PERCEPTION,, system. 
The port number has two parts: 
1) 
2) 
PERCEPTlONe: TOO - T15 (trunk PCB loca- 
tion). 
PERCEPTIONex: TOO - T15; T16 - T31 for 
the assignment of additional trunk ports, 
exceeding T15. When Ti 6 - T31 are used, 
an entry must also be made in response to 
the UPN prompt. While TOO - T15 are fixed 
trunk slots, T16 - T31 are flexible and may be 
assigned to any universal port slot (00 - 31). 
A maximum of 16 universal port slots can be 
used for trunks. 
1 - 4 (circuit number on the trunk PCB). 
For example: The port number of the third 
circuit on the PCB in position TO2 is T023. Enter: PERCEPTlONe: TNNX (port num- ,. 
ber of trunk). ‘i,( 
PERCEPTION,,: See UPN prompt. 
NOTE: 
NN = Trunk PCB number; X= Circuit number. 
UPN (Universal Port Number)-Identifies the 
hardware location of the trunk circuit that is to be 
defined in a PERCEPTlONe, system which has 
trunks assigned above T15. The universal port 
number’s trunk PCB location is TOO - T31. 
Enter: NN (NN = 00 - 31). 
NOTE: 
When reprogramming universal port assign- 
ments from trunk to station ports (and vice 
versa), all ports on the existing PCB must be 
deleted prior to entering the new port assign- 
ment. 
GMN (Group/Member Number)-The group/ 
member number identifies the trunk position in 
the system. The GMN is composed of two parts: 
1) Group (GG) Number (defined in the DTGP . ..-. 
Program): Identifies the trunk as being a ‘. 
member of that group (00 - 15). 
2) Member (MM) Number: A unique number is 
given to each trunk in a group. The numerical 
order of the number will determine the order 
in which the trunks will be selected upon dial 
access. The highest member number will be 
selected first. (PERCEPTlONe: 00 - 63; 
PERCEPTlONe,: 00 - 63). 
Enter: GGMM (Group and Member Num- 
ber). 
NOTES: 
1. GMN cannot be altered by CHG proce- 
dure. The GMN prompt will be followed by 
the existing GMN. 
2. To change the GMN, the Data Blockmust 
be deleted (OUT) and a new Data Block 
(NEW) must be entered. 
TKID (Trunk Name)-Indicates the alphanumeric 
name assigned to a particular trunk for CO, FX, 
and WATS only. When a call is coming in via a 
named trunk, the receiver can see in the LCD 
display who the call is intended for. This feature 
9-8  
						

							better enables the receiver to handle the call. 
Trunk Name also appears on outgoing calls. 
Enter: Trunk name (A - Z, 0 - 9, [space]), 
NONE. 
NOTE: 
The maximum number of alphanumeric char- 
acters a//owed for a trunk name is 16. 
TDN (Trunk Directory Number)-For private lines 
only (Trunk Group 15-PVL). TDN defines a 
directory number that will be used to assign 
private lines to a station. 
Enter: 1 - - 3-digit directory number. 
RAD (Remote Access Day)-A “Y” response en- 
ables the Remote Access to Services trunk for 
both day and night service. An “N” response 
enables Remote Access only during night service. 
Enter: Y or N. 
NIT(Night Number)-Assigns the night station for 
the trunk. Incoming calls on the trunk will ring the 
night station whenever the system is in night 
service. If NONE is entered, then the call will 
activate the UNA signal. This parameter can also 
be entered and changed by the attendant con- 
sole. 
Enter: Night station number (maximum: 4 dig- 
its) or NONE (UNA). 
NOTE: 
To assign a ground-start trunk to Remote 
Access to Services, enter the same DN that 
was used for the REM entry in the System 
Data Block (DSYS Program) for NIT (Night 
Number). 
DAY (Day Number)-Assigns the day station(s) for 
the trunk. Incoming calls on the trunk will ring the 
day station(s) when the system is not in night 
service. Up to eight stations can be entered as day 
stations, to have ,either immediate or delayed 
ringing. Delayed ringing is achieved by entering a 
9 immediately after each station number that is to 
ring after the immediate-ring station(s). This will 
delay the ringing of these stations for the period 
set by the Delay Ring Timer in the DSYS Program 
(0 - 99 seconds). After this time period elapses, 
the delayed station(s) will ring. All day stations will 
receive an immediate visual LED indication with 
PROGRAMMINGPROCEDURES 
SECTION 200-255-309 
FEBRUARY1992 
each incoming call. A Day Number can also be 
assigned as the attendant console, but the At- 
tendant Console cannot be included as part of 
delayed ringing. ACD pilot numbers cannot be 
used as part of delayed ringing either. If NONE is 
entered, the following occurs: If TEN = N in DSYS, 
calls will load share between the two consoles in 
the DAY mode, and will activate the UNA device 
in the NIGHT mode. If TEN = Y in DSYS, trunks 
assigned to TEN 0 will ring AlTO in the DAY mode 
and UNA 0 in the NIGHT mode; trunks assigned 
to TEN1 will ring ATT1 in the DAY mode and 
UNAI in the NIGHT mode. The DAY parameter 
can also be entered and changed by the attendant 
console. 
Enter: Day station number (up to 8 numbers 
maybeentered; maximum:4digitseach). 
After each station number that is to have 
delayed ringing, enter a i. Enter a space 
after each DN and/or DN p assignment. 
AlTO orATT1 (attendant console0 or l), 
or NONE (UNA in NITE service-ATT in 
Day Service). 
TRCL (Destination for Transfer Recall Termina- 
tion)--Assigns the destination to which a transfer 
recall terminates. When a transfer recall is not 
answered at the originally transferring station, the 
call can be routed to either an attendant, the sys- 
tem UNA device, or an alternative DN. 
Enter: AlTO, Al71 -Attendant Console 0 or 1. 
UNA-System UNA device. 
DN-Alternative station (either a station 
user DN or a master hunt DN). 
NONE-No termination destination (the 
call will continue to ring at the originally- 
transferring station). 
SIG (Signaling)-ldentiies the type of signaling to be 
used on the trunk circuit: 
Enter: GRD-Ground Start. 
LOP--Loop start. 
EAM-E&M. 
LDR-LoopDialRepeating(forDIDtrunks). 
DIS (Disconnect Supetvision~lnfotrns the system 
whether or not supervision can be expected when the 
distant end disconnects. Disconnect Supervision 
controls trunk-to-trunk connections for ground start 
trunks. 
Enter: Y or N. 
9-9  
						

							PROGRAMMING PROCEDURES 
SECTION 200-255-309 
FEBRUARY 1992 
CTL (Control 
of Disconnect)-Defines the re- 
lease control of TIE, DID, or CCSA connection. 
Enter: OPC (Originating Party Control)-The 
circuit will not be released until the trunk 
that originated the call disconnects. 
FPR (First Party Release)-The trunk 
at either end of the connection can 
release. 
DIN (incoming Dialing)-Informs the system of 
what type of dialing to expect on an incoming 
call. (This prompt is for TIE, CCSA, and DID 
trunks only.) 
Enter: DIP-Dial Pulse. 
TON-DTMF. 
DOT (Outgoing Dialing)-Informs the system of 
what type of dialing to expect on an outgoing call. 
Enter: PlO = Rotary Dial IO PPS. 
P20 = Rotary Dial 20 PPS. 
TON = DTMF. 
OTR (Private Line Outgoing Call Restriction)-- 
This prompt will only appear if the trunk is a 
member of the private line trunk group (Group 
15). The OTR prompt is used to exclude selected 
stations from making outgoing calls over the 
private line. Consequently, these lines can be 
used only for answering incoming calls. If a 
private line appears on more than one station, 
then each station can be individually restricted 
from using the line for outgoing calls by entering 
the port number of each DN that is to be re- 
stricted (LNNX). Following the OTR prompt, the 
system will prompt “D” and any entries made will 
be deleted. To add entries, press the carriage 
return m key. An “A” prompt will appear and 
any entries made will be added. 
Enter: LNNX LNNX (in response to the D 
prompt)-To delete a station port. 
LNNX LNNX (in response to the A 
prompt)-To add a station port.
