4.12 This completes the mechanical installation of the SMarT-1’” 
Security Access Controller. Continue by programming the unit 
from the terminal.  Refer to Figure 4-3. Connect a suitable Earth Ground to the 
screw mount 
[Al provided on the connector panel. This connec- 
tion MUST be made for the unit to function properly. 
Plug the Power Pack jack into the Controller power connection 
[Bl. 
Plug the Power Pack AC line cord into a suitable (1 IOV-60Hz) 
AC receptacle. 
Using the supplied RJ31XKA31A cables, insert one end of a 
cable in a jack on the Controller [Cl. 
Connect the other end of the cable used in step 4 to the 
Telco-supplied jack. 
Repeat steps 4 and 5 above for the appropriate number of 
times depending upon the model of Controller being installed 
(4-, 2-, or l-line units). 
Connect a suitable terminal to the RS-232 Computer Port [Dl 
via a suitable cable. Configuration of this cable is described in 
paragraph 4.13 below. 
RS-232 Port Configuration 
4.13 The RS-232 Computer Port connector (refer to Figure 4-6) is a 
female connector configured as “DCE”. Only the TxD (pin 3), the 
RxD (pin 2), and the GND (pin 1) lines are used by the Controller. Pins 4 
through 6, 8, and 20 are shorted internally for the convenience of the 
user. This port is used for programming and call recording output. 
4.14 During programming, a suitable terminal must be connected to 
this port. For call recording output, a suitable printer is con- 
nected in place of the terminal. Refer to Part 6 paragraph 6.05 for the 
configuration of the terminal or the printer.

5. OPERATING DESCRIPTION 
SECURITY 
5.01 
The primary function of the SMarT-1’” Security Access Control- 
ler (SAC) is to provide security to connected systems such as 
Modems and to protect these systems from unauthorized telephone 
access. The security provided by the SAC lies in three distinct areas. 
These areas are: 
l The use of optional progress tones, or lack thereof, to make it 
difficult for an unauthorized caller to recognize that there is 
protected equipment connected to the telephone line. 
0 
The inclusion of the callback feature to assure that only those 
individuals with valid passwords are called back at an assigned 
number associated with that particular password. 
0 
Finally, the provision of a call detail record that is available at 
the RS-232 Computer Port to record the time and duration of 
the call, along with the number that was called back. 
5.02 While it is not recommended, the SAC may also be pro- 
grammed to allow instant access (circumvention of the call 
back feature) upon the- receipt of a particular password. 
5.03 Passwords must be Dual-Tone Multifrequency (DTMF) digit 
strings that range from 1 to 15 digits in length. Only a DTMF 
type of telephone can be used to access the SAC. Rotary dial tele- 
phones cannot be used since rotary digits can only be received by, but 
not transmitted through, a Central Office. 
OPERATIONAL SEQUENCES 
5.04 The steps listed below show the operational sequences of the 
Controller: 
Note: A single progress tone as used in the steps below indicates 
that the user will hear a single ‘beep’ in the receiver earpiece 
of the telephone. In a like manner, a double progress tone 
means two ‘beeps’ and a triple progress tone means three 
‘beeps’. 
1) The user dials the directory telephone number of the protected 
device with a DTMF type telephone. 
2) The SAC detects the incoming call, disconnects the protected 
equipment from the line, and answers the call. The SAC may 
then optionally provide the user with a single progress tone. 
3) The user enters his/her password by keying the correct digits 
on the telephone. This password may be from 1 to 15 digits in 
length and consists of any of the 12 standard DTMF digits. 
4) If an exact match for the password cannot be found in the SAC

6) 
internal memory, the Controller drops the line (hangs up) and 
may optionally “busy out” that particular line for a program- 
mable length of time. The unsuccessful password will be print- 
ed in the Call Detail Record. 
If an exact match for the password is found in the SAC internal 
memory, the Controller will check for the type of access that 
the password permits, including the time-of-day period as- 
signed for that particular access. 
Upon verification of a valid password during the particular 
time-of-day period, the SAC will then execute its programmed 
action for that particular password. One of three series of 
events will occur: 
? 
Automatic Callback Access: 
a) The password action is deemed to be an automatic call- 
back. For this instance, the SAC will hang up the tele- 
phone line, reseize the line and dial back to the user by 
using a preprogrammed call back number associated 
with this particular password. The user must know that 
he has to hang up, or may optionally be requested to 
hang up by receipt of a triple progress tone ,from the 
Controller. This method of access is considered to be 
the most secure making it nearly impossible for some- 
one to gain unauthorized access to the protected equip- 
ment. 
User Entered Callback Access: 
b) The password action is deemed to be a user controlled 
callback type. This means that the user must manually 
tell the controller the telephone number to be used for 
the callback. The user either must know when to enter 
his telephone number and hang up, or may optionally be 
requested to input his telephone number by receipt of a 
double progress tone, and to hang up on receipt of a 
triple progress tone. As before, the SAC will then hang 
up and reseize the line. It will dial out using the user 
entered telephone number. This action is less secure 
that the previous action since the user provides the 
telephone number. However, the call detail record will 
contain the telephone number that the user has entered 
and was called back at. 
Cut-Through Access: 
c) The password action is deemed to be a ‘cut-through’ 
type of access. In this case, there will be no progress 
tones received or any other SAC activity. At the expira- 
tion of the ‘wait for password’ time period, the SAC will 
connect the caller to the protected device. This action is 
the least secure of the three actions. While the password 
must be entered exactly and the access attempt made 
Page 24  
						

							SECTION MlTL8350-048-l OO-NA 
during the allowed time-of-day, there will be no record 
of the call with the exception of the time and duration of 
the access and the optional printing of the successful 
password. 
DETAILED OPERATING DESCRIPTION 
With Modems 
5.05 
The following assumptions are taken into consideration when 
describing the detailed operating procedures that will follow in 
paragraph 5.06: 
1) 
2) 
3) There are correctly installed and known functional Modem con- 
nections for the Central Processing Unit (CPU) and the remote 
access. Any installation should first be capable of functioning 
without the SAC device present to cut down on non-SAC re- 
lated operational questions. 
If installation problems are encountered at any time, the SAC 
device should be removed to prove that connections are possi- 
ble without the device. Otherwise, considerable effort could be 
expended when the problem is in other areas of the system. 
Persons accessing the system (users) have been previously 
advised of any necessary sequence of events required in order 
to establish a valid Modem connection. In some instances, spe- 
cialized sequences will be required. 
Automatic Callback Access 
5.06 
cess: 
1) 
2) 
3) 
Note: 
The following steps outline the operations of the Security Ac- 
cess Controller that occur when using automatic callback ac- 
The caller dials the host system over the telephone lines. 
The protected Modem senses ringing and seizes the line. With 
proper programming, the SAC then splits the line while the 
protected Modem is waiting for the line to settle (about 2 
seconds). The Modem (at the end of the line settling period) 
places an answer tone on its output to the SAC. The SAC emits 
a single progress tone to the caller. No Modem tones are 
supplied to the caller. 
The caller, after hearing the progress tone (unless disabled), 
must enter the assigned password via DTMF dialing. Two con- 
ditions must be satisfied at this point. The first is that the 
protected Modem must be capable of answering in the answer 
mode for a programmable period of time that is sufficient to 
allow the callback to occur. The second is that the called back 
Modem must be capable of being forced into the originate 
mode upon receipt of the callback. 
A more efficient variation of the above description would be 
that the protected Modem answer the incoming call in the

Note: 
originate mode (waiting for answer tone) for a period of time 
long enough to allow the callback to occur, as previously 
mentioned. In this case, the callback could be automatically 
answered by the Modem that is accessing the host system. 
These events depend upon the sophistication of the Modems 
and the ingenuity of the user. 
After a programmable period of time, the SAC will drop the line. 
The SAC will reseize the line if the password is valid, and will 
dial back the caller via the use of speed dialing. 
If the protected Modem is waiting for an originate tone (via 
programming), the calling Modem may simply answer the call 
automatically, thus establishing the connection. The SAC will 
cut-through upon the completion of it’s call back and connect 
the two Modems. 
If the called Modem is waiting in the answer mode (most 
common used mode), the caller must place his Modem into the 
originate mode upon receipt of the callback. 
Once connection is established, the SAC ‘goes to sleep’ and 
appears as a direct through connection to the two Modems. 
Call disconnection is accomplished as per normal operation, or 
at a loss of carrier detect at either Modem. 
In the 2- and 4-line models, the SAC is continually monitoring 
the other unused lines while the above procedure is taking 
place. 
User-Entered Callback Access 
5.07 The following steps outline the operations of the Security Ac- 
cess Controller that occur when using user entered callback 
access: 
1) The caller dials the host system over the telephone lines. 
2) The protected Modem senses ringing and seizes the line. With 
proper programming, the SAC then splits the line while the 
protected Modem is waiting for the line to settle (about 2 
seconds). The Modem (at the end of the line settling period) 
places an answer tone on its output to the SAC. The SAC emits 
a single progress tone to the caller. No Modem tones are 
supplied to the caller. Two conditions must be satisfied at this 
point. The first’ is that the protected Modem must be capable of 
answering in the answer mode for a programmable period of 
time that is sufficient to allow the callback to occur. The second 
is that the called back Modem must be capable of being forced 
into the originate mode upon receipt of the callback. 
3) The caller, after hearing the progress tone (unless disabled), 
must enter the assigned password via DTMF dialing. Upon vali- 
dation of the password, the SAC will emit a double progress 
tone to the caller. 
4) The caller, after hearing the double progress tone (unless dis-
