QUITTING PROG. MODE 
Figure 7-1, Terminal Display of Data Entry Check 
7.09 The Controller is now ready to be placed into service for the 
purposes of the above example. Assuming that the power has 
been applied for a sufficient length of time, it is safe to unplug the 
Controller and to install it on a telephone line between a Modem and 
the outside telephone wires. No programmed data will be lost. For 
more information on installation, refer to Part 4, page 13. For a more 
detailed explanation of programming, refer to page 42 of this Part. 
TESTING THE CONTROLLER INSTALLATION 
7.10 Some of the activity as described in the Theory steps below is 
caused by additional default data that is resident in the Con- 
troller. More complete details of operation are described in later para- 
graphs. Prior to proceeding with the testing, install the Controller as 
outlined in paragraphs 7.06 through 7.09 above. 
Modem Setup 
7.11 
Ensure that the protected Modem is set up with the following 
parameters: 
1) Answer at the end of the first ring (i.e., after 2 seconds of 
ringing). 
2) To look for originate tone for 45 seconds (this parameter may 
require fine tuning). 
3) To disconnect on loss of carrier. 
Theory of the Test 
7.12 The Modem will answer the line within 2 seconds. In an addi- 
tional 2 seconds later (after line settling time), the Modem will 
Page 37  
						

							SECTION MITL8350-048-l OO-NA 
begin transmitting an answer tone. In 3 seconds, however, the Con- 
troller will electrically separate the Modem from the line and take over 
the telephone call. Thus, the Modem is split away from the telephone 
line before it can begin transmitting the answer tone. The Controller 
supplies the loop current to the Modem during this split mode. This 
loop current allows the Modem to believe that the telephone call is 
still present. 
7.13 Upon answering, the Controller transmits a progress tone (one 
beep, if enabled), indicating that the caller should enter a pass- 
word. The Controller will remain in the ‘waiting for password’ state for 
8 seconds (programmable). At the end of the 8 second waiting period 
and the acceptance of DTMF digits, the Controller will stop accepting 
digits. The Controller will then analyze what it has received, and, if it 
was a valid password (12345 in our example above), will emit a triple 
progress tone (three beeps, if enabled) indicating that the password 
has been accepted. This indicates that the caller should terminate the 
call and should wait for the callback to his telephone line. The Control- 
ler will remain on the line for 5 more seconds (programmable). It will 
then hang up and initiate its own telephone call as determined by the 
‘7345’ coding (3931212 in the example above). . 
7.14 As the Controller dials the last digit of the callback number, it 
reconnects the Modem to the telephone and drops off the line. 
From this point, and on until the call is terminated, there is no further 
activity or interference by the Controller. 
7.15 When the Modem drops the line (hangs up), a Call Detail Record 
will be made available at the RS-232 Computer Port. This re- 
cord will show the time of the call, the duration of the call, and the 
password that was entered. The password field may be turned off 
(disabled from printing the password) by programming if desired. Refer 
to Paragraph 7.85. 
7.16 On callback to the user (when the user’s telephone rings), the 
user’s Modem must be placed in the ON-LINE and ORIGINATE 
modes. On answering the incoming call from the Controller, an answer 
tone will be received from the protected Modem. Once the user’s 
Modem senses this answer tone and responds to it with an originate 
tone, the Modem connection will be established. 
7.17 Termination of the call will occur on the loss of carrier 
(hang-up). This loss of carrier will cause the protected Modem 
to drop the telephone line. The Controller will detect the termination of 
call as a loss of line current. At this time, the Controller will prepare to 
accept further accesses. 
Actual Testing 
7.18 
The steps listed below describe the actual testing of the Con- 
troller as installed for Callback Operation: 
1. Place a call to the protected Modem without entering a pass- 
word. The Controller should time out in approximately 11 sec- 
Page 38  
						

							SECTION MlTL8350-048-l OO-NA 
onds after ringing. This 11 second period includes 3 seconds 
after start and 8 seconds of waiting for the password digits. 
After time out, the Controller will keep the Modem separated 
from the line and holds the line busy for an additional 20 
seconds. The controller should return to the ‘waiting for ringing’ 
mode. If this occurs, the call has been successfully denied. 
2. Place a call to the protected Modem and enter an INVALID 
password. Once again, the Controller will keep the Modem sep- 
arated from the line and holds the line busy for an additonal 20 
seconds. The controller should time out in 11 seconds and 
return to the ‘waiting for ringing’ mode. If this occurs, the call 
has again been successfully denied. 
3. Place a call to the protected Modem. The Modem should an- 
swer the call within 2 seconds. The Controller should split the 
Modem away from the line in 3 seconds and send a progress 
tone (beep). Enter a valid password. In approximately 15 sec- 
onds, the Controller should begin dialing out the digits of the 
callback number. This last 15 second period includes 8 seconds 
of waiting for password digits, 5 seconds to allow the caller to 
hang up, and approximately 2 seconds for the Controller to 
drop and reseize the line. 
Approximately 18 seconds should elapse between the protected 
Modem ringing and the initiation of the Callback function. Al- 
lowing IO seconds for the acquisition of dialtone, dialing the 
number, and for ringing to start at the user’s telephone, this 
leaves the user with approximately 17 seconds to answer the 
call with the user’s Modem in the ON-LINE and ORIGINATE 
modes. This time period occurs since the protected Modem has 
been programmed to drop the line in 45 seconds. 
7.19 If it is found to be undesirable to allow the caller to hear the 
protected Modem’s answer tone before the line split occurs, it 
may be necessary to fine tune the Controller and the Modem answer 
timing until the Controller takes over the control of the line within 2 
seconds after the Modem answers the line. 
7.20 In general, the Controller timing can be programmed to adapt 
to most situations encountered as long as the protected Mo- 
dem is capable of remaining ON-LINE for a long enough period to 
allow call completion. Refer to Figure 7-2 for a graphic representation 
of the Modem and Controller timing. 
PROGRAMMING FOR USER-ENTERED CALLBACK NUMBER OPERA- 
TION 
7.21 User entered Callback number means that the caller will, upon 
entry of a valid password, be requested to enter the telephone 
number (and the ‘#’ terminator to indicate end of number) that the 
Controller will use to call back. This method differs from the previously 
described method in that the SAC does not determine the callback 
number from the interpretation of the password. The password, in this

The programmer must take care to avoid assigning a

Note: 
The first carriage return in the description above causes the 
Controller to enter the programming mode. The second line of 
the description is the entry of the password, callback code, 
and time-of-day access code. For the purposes of this dis- 
cussion, the password will be ‘76278’ and the access code of 
‘10’ is wait for the caller to enter the password and access is 
granted 24 hours a day, respectively. Refer to page 60 for a 
complete description of password entry. 
7.22 This completes the necessary programming for a user entered 
callback number. The Controller will now wait for 16 seconds 
after the 8 second wait for password period, to allow the caller to 
enter the callback number.

7.23 The caller MUST enter the callback number followed by the ‘#’ 
terminator to indicate end of number, in the same exact manner 
as if it were being dialed from the protected Modem. This is particu- 
larly true if the callback number is a long distance number. Informing 
the callers of the procedures to use is left up to the Controller man- 
ager. 
7.24 There will be a single progress tone heard in the receiver to 
inform the caller to enter the password. A double progress tone 
(two beeps) will be heard to request entry of the callback number. 
Finally, a triple progress tone will be issued to request that the caller 
hang up. The timing sequence for the events is the same as those in 
Figure 7-2 except for the addition of a 16 second period to wait while 
the Controller waits for the caller to enter the callback number. 
7.25 Any or all of the request progress tones may be disabled if 
desired by programming. Refer to Page 51 for more information 
on disabling progress tones. 
Program Verification

gramming data was entered correctly for User-Entered Callback 
Number Operation:

ple under ‘Programming for Callback Operation’. These are

7.29 
If the Controller was left installed while it was being pro- 
grammed, the programmer may go directly to testing the user- 
entered callback password. It is not necessary to remove the Control- 
ler from service while it is being programmed. _ 
DTMF CUT-THROUGH ACCESS 
7.30 
This is the least secure method of access to the Controller. The 
method provides no callback number, automatic or otherwise. 
Depending on the action digits programmed, the time and date of 
access and password may optionally be printed in the Call Detail 
Record. 
7.31 Programming simply consists of entering the password along 
with the proper action digit, along with the time of day access 
code. Refer to Page 60 for a complete description of passwords and 
action digits. When the dialed password has been analyzed 
(approximately 8 seconds after answering the call), the Controller will 
immediately connect the caller to the protected Modem, if the pass- 
word is valid. 
DETAILED PROGRAMMING DESCRIPTIONS 
7.32 
The following paragraphs outline the parameter descriptions in 
the order that they appear in later parts. These parameters help 
to describe the complete Controller capabilities and show its versa- 
tility. They are: 
1. 
SYSTEM PARAMETERS - System parameters are those that 
affect the system-wide operation of the Controller. They in- 
clude: 
a. 
SPECIAL PARAMETERS 
- These parameters allow data 
confirmation, the setting of time and date, and the load- 
ing of default data base, etc. 
b. 
OPERATIONAL PARAMETERS - These parameters affect 
the Baud rate, the Call Detail Recording format, etc. 
2. 
TRUNK RELATED PARAMETERS - These parameters affect in- 
dividual trunk activity and capabilities such as the type of Cen- 
tral Office, and dialing type. 
Page 42  
						

							SECTION MlTL8350-048-I OO-NA 
3. PASSWORD PROGRAMMING - This part includes the program- 
ming of the password itself. It also describes the accompanying 
codes that will control whether or not the password is printed 
in the Call Detail Record, the time of day that the password will 
be accepted, and the action to perform upon acceptance of the 
password. Programming is required in this area for either auto- 
matic callback operation, user-entered callback numbers, or cut 
through access. 
4. AUTOMATIC CALLBACK PROGRAMMING (SPEEDCALLS) - This 
programs the area where the numbers to be dialed out for an 
automatic callback triggered by the password are stored. This 
area includes the programming of a selected ‘route’, if desired. 
For other modes of operation, no programming is required in 
this area. 
5. SEARCH TABLES - Callback numbers are normally passed 
through the ‘Search Tables’ in order to decide which ‘route’ the 
callback will be placed on. If the standard DDD route is used for 
callbacks (no ‘Other Common Carrier’ 
used), it will probably not 
be necessary to program these parameters. The default entries 
will handle most cases, whether the calls are long distance or 
local. 
This area, if programmed properly, could be used to prevent 
callbacks to certain geographical areas or to prevent any long 
distance calls whatsoever, or to determine what types of dial 
out will be allowed in general (user-entered in particular). Both 
automatic and user-entered callback numbers may pass 
through these search tables prior to the controller dialing. An 
instruction to deny calls to a particular area code at this point 
would not allow the call to that area code even if it were 
entered in the Automatic Callback Programming data. 
6. ROUTE RELATED PARAMETERS - Routes, as defined for the 
Controller, are dialing sequences, control of dialtone detection, 
the sequence of digits to be dialed out, and other related de- 
tails. A route is actually better defined as the instructions that 
the Controller uses in accomplishing the callback function. 
The default programming that is resident in the Controller will 
place all callbacks on the DDD Route (normal dialing through 
ATT or whatever standard service is being used). In the event 
that a customer is using an ‘Other Common Carrier (OCC)’ such 
as SPRINT, MCI, etc., these ‘routes’ may be programmed contain 
the information for automatic entry of the authorization codes, 
etc. 
System Parameters 
7.33 Table 7-2 on the next page contains System Special Parameters 
while Table 7-3 (page 47) contains System Operational Param- 
eters. These parameters include default, if applicable, and a description 
of the options available when entering the parameters.

CAUTION - This command 
deletes all callback instructions that are resident in the 801 
through 815 and 821 through 835 Search Tables. The Con- 
troller cannot operate without data entered in these tables. 
The only reason for erasing this data is if the user wishes to 
restart with an entirely new data program and where it is not 
convenient to delete the old data one piece at a time.

‘’ where  = Carriage Return. A maximum of ‘I5 
characters may be used for the entry. 
7.34 X, x, 999 - Exit program mode. These commands may be used 
to exit from a programming session. Either the ‘X’ or ‘x’ com- 
mand may be used anywhere in string entry to cause the Controller to 
immediately exit from the programming mode. The ‘999’ command is 
only used to exit from a programming session when all programming 
has been completed. The terminal display will reply with the message:

Note: 
If X’ or ‘x’ are used to exit programming, the message will be 
printed, but the [9991 entry in the example above will be either 
[XI or [xl respectively. In the example above and in the exam- 
ples to follow, user entered data is enclosed in the brackets 
[

All other data not enclosed in the brackets is data that the 
Controller sends to the terminal display. 
7.35 The Controller, after sending the message to the display, exits 
programming mode. To re-enter the programming mode, the 
user must type a  on the terminal keyboard.

7.36 980 - Enter Date and Time for Call Detail Record and Time- 
of-Day Access Control. This command must be followed by the 
two digit groups for the current month, day, hour, and minutes (format 
mmddhhmm). The command sets the internal clock of the Controller. 
This internal clock is used for the time printout on the Call Detail 
Record. It is also used to determine if access is allowed due to the 
time-of-day programming by comparing the actual time of call against 
the preprogrammed time-of-day parameter. 
7.37 A typical entry for a ‘980’ parameter for January 28, 09:26 AM 
would be: 
> [980012809261 
> 
7.38 902 - Enter Data Confirmation Mode. This command causes the 
controller to leave the programming mode and enter the data 
confirmation mode. This mode allows the programmer to verify that 
the Controller has received the programming data correctly into the 
internal memory. Once entered, the command causes the Controller to 
return the > prompt to the display. The Controller then expects the 
programmer to enter a parameter to be checked. Once entered, the 
controller will space on the display and show the characteristics of 
that particular parameter. For example, if a check were made of the 
machine identifier as entered in paragraph 7.06, the following steps 
would be accomplished: 
> 19021 
> 16021 
546F6D 
> [9071 
> 
Note: 9xX parameters are commands and therefore, not verifiable. 
7.39 907 - Exit Data Confirmation Mode. The ‘907’ command causes 
the Controller to exit from a data confirmation session and to 
return to the programming mode. A typical example of this is shown 
above where the ‘602’ parameter was checked for accuracy. 
7.40 942903 - Load Factory Installed Default Database. This com- 
mand should be used with caution. It will cause the Controller 
to delete all previous programming data and to install all default 
database parameter settings. In Tables that follow, these default pa- 
rameter settings are listed in column 2. The example below shows the 
manner of entry. 
> [9421 
> [9031

7.41 942904 - Delete All Search Table Entries. This is another com- 
mand that should be used with extreme caution. It causes the 
Controller to delete all data that has been entered in the 801 through 
Page 45  
						

							SECTION MITL8350-048-l OO-NA 
815 and 821 through 835 Search Tables. If only a few entries in these 
tables are to be changed, it is recommended that the parameters to be 
changed be programmed singularly. This command should only be 
used if there are too many parameters to be changed one at a time 
and it is desired to re-enter the complete programming for all the 
Search Tables. Note that the Controller cannot function properly with- 
out data in these tables. 
Note:

> After deleting all search table entries with the 942904 com- 
mand, the default data base can be reloaded by entering a 
942903 command. 
[9421 
[9041 
7.42 601 - Area Code of Other Common Carrier (OCC). If the OCC 
requires an area code entry for dialing, it should be entered 
with this command. Command data entry should be followed with the 
end of entry indicators ‘BB’. The data to be entered must be 3 digits in 
length, if used. If not used, the default data for this entry is ‘000’. For 
example, if the area code for the OCC was ‘613’, it would be entered as 
follows: 
> [601613BBl 
> 
7.43 602 - Machine Identifier for Call Detail Record Output. This 
command allows the programmer to enter a character or group 
of characters that will be printed on the Call Detail Record. It appears 
on the far right side of the printout. Note that only three characters 
will be printed, regardless of the length of the identifier over three 
characters. If the identifier is under four characters, all will be printed. 
The identifier must be entered as ASCII characters. Refer to Appendix 
C, Table C-l for ASCII equivalents. The command data must be termi- 
nated with the ‘BB’ terminator. The default for this command is ‘SAC’. 
For example, if the Controller is to be identified as ‘CHICAGO’ (only 
‘CHI’ will appear in CDR output), it would be programmed as: 
> [6024348494341474FBBl 
> 
7.44 604 - Terminal Program Security Code. This command allows _ 
the programmer to change the security code required for entry 
into programming. The security code default on initialization is ‘‘. 
Once initialized, the unit enters immediately into the programming 
mode if the security code has not been changed. The data for this 
entry is limited to 15 characters maximum and must be entered in 
ASCII format. The data string entered must be followed by the ‘BB’ data 
entry terminator. Refer to Appendix C, Table C-l for the ASCII equiv- 
alents. For example, if a programmer wished to change the security 
code to ‘BOB’, the entry would appear as:
