							member number will be selected first. 
Enter: Group and Member Number 
(GGMM) 
NOTE: 
1. GMN cannot be altered by CHG pro- 
cedure. The GMN prompt will be fol- 
lowed by the existing GAIN. 
2. To change the GMN, the Data Block 
must be deleted (OUT) and a new 
Data Block (NEW) entered. 
TDN (Trunk Directory Number)-For Private 
-- 
Lines Only (Trunk Group PVL); defines a 
phantom directory number that will be used 
to assign private lines to a station. 
Enter: 3-digit number 
[\IIT (Night Number)-Assigns the night station 
for the trunk. Incoming calls on the trunk will 
ring the night station when the system is in 
night service. If NONE is entered, the call 
will activate the UNA signal. This parameter 
can also be entered and changed by the atten- 
dant console. 
Enter: Night station number or NONE 
SIG (Signalling)-Identifies the type of signal- 
ling to be used on the trunk circuit: 
Enter: GRD - Ground Start 
LOP - Loop Start 
EAM - E&M 
LDR - Loop Dial Repeating 
OAD - Outgoing Automatic, ln- 
coming Dial 
DIS (Disconnect Supervision)-Informs the sys- 
tem whether or not supervision can be ex- 
pected when the distant end disconnects 
(controls trunk-to-trunk connections). 
Enter: Y or N 
CA (Control of Disconnect)-Defines the re- 
lease control of TIE, DID or CCSA connection. 
Enter: OPC: Origination Party Control, 
circuit is not released until 
the trunk that originated the 
call disconnects. 
FPR: First Party Release, either 
trunk can release the con- 
nection. 
DIN (Incoming Dialing)-Informs the system 
of what dialing type to expect on incoming calls. For TIE, CCSA, DID trunks only. 
Enter: DIP - Dial Pulse 
TON - DTMF 
DOT (Dialing Outgoing)-Selects the type of 
dialing to be used on outgoing calls. 
Enter: PI0 - Rotary Dial 10 puIses/sec. 
P20 - Rotary Dial 20 pulses/set. 
TON - DTMF 
@ (Answer Supervision for TIE, CCSA, DID 
trunks only)-Determines if answer supervision 
will be provided to the distant trunk on in- 
coming calls. If “Iv” is entered, the system will 
not return answer supervision. 
Enter: Y or N 
Once the system data has been recorded 
in the System Record, connect the data terminal 
and input the data to the system as explained in 
the following paragraphs. 
ata Terminal connection 
A keyboard/printer terminal (Texas In- 
ents Model 743/745 or equivalent) is required 
to communicate with the PERCEPTION system. 
2 
The terminal is connected to the system 
a female-type RS232C connector (labeled 
TTY) located on the connector panel on the lower 
rear of the DCEC. 
41 
In addition to the TTY connector, 
a MODEM connector is provided. By attaching 
a customer-provided “answer only” modem, 
all functions normally performed by the local 
terminal can be performed from a remote 
location. 
0 
The TTY and MODEM ports can operate 
at a speed of 300 or 1200 bps, and utilize a stan- 
dard 7-level ASCII code with one start bit, one 
stop bit and one parity bit. The system transmits 
even parity and ignores the parity bit on the 
receive side. The speed is selected by a push-on/ 
push-off switch located on the front of the DPEU 
PCB. The associated LED is on when 1200 bps 
is selected. 
The speed selection is made simul- 
taneously for the TTY and MODEM ports. These 
two ports are wired in a logical “OR” fashion and  
						

							cannot be used at the same time. One must be 
“open”. 
04.16 The pin assignments of the TTY and 
MODEM connectors are:

The data terminal connector is located 
in the rear (lower left) of the DCEC. Four female 
25-pin EIA type connectors are provided in a 
vertical row. Looking from top to bottom the 
connectors are labeled: 
- TTY 
-MODEM 
- SMDR 
- DATA 
Plug the terminal into the TTY connector. 
Cl The data terminal should be set for the 
proper speed and for full duplex operation before 
&itching its power on. 
To prevent unauthorized tampering with 
the Customer Data base, the PERCEPTION system 
requires an authorization code to be entered before 
any Utility Program can be called up. This auth- 
orization must be entered prior to requesting each 
utility. 
There are three levels of authorization 
(each of which has a unique 4-digit code that is 
assigned in the system memory). When shipped from the factory, all levels are assigned 6000. 
Codes are changed with the Authorization Code 
Change procedure (DCHG). 
04.23 The activity granted to each level is as 
follows: 
Level 1: 
Can do all activities of Levels 2 and 3. 
Can change the 4-digit codes of Levels 
1,2,and 3. 
Level 2: Can do all Level 1 activities except 
change Levels 1 or 2 codes or read out 
Level 1 code. 
Can change Level 3 code. 
Level 3: 
Normally assigned for end user use. 
Can change: Station 
Speed Dial Data 
Call Pickup Groups 
Hunt Lists 
Can request data dump. 
24 To execute the Authorization Pr 
teed as follows: 
1) Plug in and power up data terminal. 
2) Depress the carriage return key. 
The system will respond by printing 
“COD” and will print several characters 
on the spaces to be occupied by your next 
entry (this isdoneto mask the authorization 
code). 
3) Enter the 4-digit code, follovved by a carriage 
The system will print: 
“ERROR” if invalid code is entered 
(return to step 2). 
“OK” if valid co e is enlered (proceed 
to request Utility Program). 
Utilit 
Execute the Authorization  
						

							then enter the mnemonic of the required Utility 
Program after the system responds with “OK”. 
.32 After the Utility Program name is entered, 
the program is loaded from the diskette. When the 
loading is complete, the system will prompt 
“R EQ”. 
.33 Inputting data via a Utility Program is 
a matter of responding to the prompts given by 
the system via the data terminal. The prompts 
and the required responses are mnemonics that 
are usually abbreviations of the actual English 
word required. 
If an improper response is made to a 
prompt, the system will respond with an error 
message. The error message will be a “?” when 
the error is obvious but in most cases it will be an 
alphanumeric code. The alphanumeric code con- 
sists of four letters identifying the program in 
use and two numbers identifying the error. 
.35 Brackets are used to indicate control 
code keys on the programming terminal. The 
[CTRL] (control) key must be held down while 
simultaneously depressing [Xl or [HI. Depress 
the carriage return key whenever [CR] appears. 
The following control codes are available when 
using Utility Programs (depress [CR] after each 
code) : 
[CTRL] [Xl - Ignore line entered-same prompt 
will be repeated. 
[CTRL] [HI - Backspace-will allow you to 
overwrite the previous charac- 
ter(s). 
[DELI - May be entered anytime-sys- 
tem will stop execution and 
return to “R EQ” prompt. 
[DEL] [DELI-Abort program-ends use of 
one utility, system will respond 
with “SAVE”. A “Y” entry 
will cause the system to copy 
all present 
data onto the dis- 
kette. If more changes are to 
made, enter “N”. 
When data already exists for a given 
prompt and a change is not required, entering a 
[CR] will advance to the next prompt without 
changing existing data. 
.37 Tables D through AC show the format 
of each Utility Program. If applicable, each table 
is followed by a list explaining the error codes 
pertaining to that program. Using the appropriate 
tables as guides, enter data previously recorded in the System Record. 
0 Authorization Codes Change (Table C) 
1 The DCHG Program changes the auth- 
rization codes used in the Authorization Pro- 
cedure. 
2 
To use the DCHG Program: 
Complete the Authorization Procedure 1 Level 
1 or 2). 
Enter: DCHG [CR] (in response to OK 
prompt) 
The next prompt will be: 
Ll XXXX (Level 1 authorization code) 
(XXXX = present code) 
NOTES: 
1. If Level 2 authorization code was given 
above, L I will not be output-go to next 
prompt (L2). 
2. If Level 3 authorization code was entered 
above, an error message will be given- 
Level 3 cannot change the authorization 
codes. 
Enter: New Ll code (4 digits) [CR] 
L2 XXXX (Level 2 authorization code) 
(XXXX = present code) 
Enter: New L2 code (4 digits) [CR] 
L3 XXXX (Level 3 authorization code) 
(XXXX = present code) 
Enter: New L3 code (4 digits) [CR] 
Ll or L2 Program repeats 
Enter: [DEL] [DEL] (to 
abort program) 
05.01 The data output procedures allow the 
maintenance terminal to request a printout of 
the data contained in the various system Data 
Blocks. 
05.02 The Authorization Procedure must be 
performed before requesting a printout procedure.
