DeesLink
Technical Product Documentation
1. Overview Description
The DeesLink supports the telecommuting applications of remote access to an office telephone system
and or access to specific telecommunication equipment such as the CM-30 Call Monitoring system.
The DeesLink allows authorized remote workers or clients to gain access to specific system functions
within the office environment or gain access to two different ports, A and B within DeesLink, which can
be connected to auxiliary telephone equipment.
Complete system administration and security capabilities are provided with the DeesLink. The unit can
be programmed on site or remotely through a DTMF telephone. It provides programmable functions
such as: password security, dialing restrictions, release time and port A or B access.
Getting Started
This manual was written for the system administrator (designated as User 1) and an installer.
The system administrator manages all passwords and other programmable functions.
A detailed record should be maintained by the administrator of all passwords issued as well as all
dialing restrictions that have been set up for specific users.
Line Requirements: The incoming line should be loop start with forced disconnect. The
outgoing line or equipment on the DeesLink must be loop start. If you are using a loop start line
without forced disconnect for the incoming line, the switching platform must deliver dial tone,
busy tone or reorder when the caller disconnects. The time-out period for the DeesLink must be
programmed to ensure timely disconnect.
2. Modes of operations
Accessing
To access the unit, the remote user dials a directory number assigned to the DeesLink. DeesLink will
answer incoming ringing during the second ring cycle, whereupon it will return an acknowledgement
tone (one beep). After receiving the acknowledgement tone, the user should proceed to input (DTMF)
their specific password code. Upon acknowledging the code as valid the DeesLink will return a Ready
tone (2 beeps). The user is now connected to either port A or port B, depending upon the password code
inputted. User stays accessed to the unit for a prescribed period of time (setup by system administrator at
time of programming the unit) if disconnect is not initiated by user.

Disconnect
The remote user can signal the DeesLink to release the call (hang up) by entering the command ## from
their DTMF phone.
If the user doesn’t enter the disconnect command of ## before hanging up, the DeesLink will recognize
the “forced-disconnect” signal (which is normally provided on loop-start lines) and release the line.
3. Programming
Read this section carefully before beginning to program the unit.
System Administrator
The system administrator is by default User 1. Only User 1 can program the unit locally or remotely.
User 1’s default password is (please contact Dee Communiationss).
IT IS EXTREMELY IMPORTANT THAT THIS NUMBER NOT BE GIVEN OUT
INDISCRIMANATELY. UNAUTHORIZED USE OF THIS PASSWORD COULD RESULT IN
INVALID REPROGRAMMING AND FURTHER SECURITY RISKS.
Basic Programming
Users: DeesLink supports 1 to 8 users including User 1, the System Administrator. The User number is
the first digit (1-8) after the initial (*) required at the beginning of each programming string.
CM Port Access Assignments
The system administrator defines Port access assignments. Port access is indexed to the user’s password.
Each unique password (code) is only allowed access to one port either Port A or B. The User number
assigned to an individual determines what CM Port they will be connected to upon accessing DeesLink.
Users 1 through 4 will automatically be connected to CM Port A upon access.
Users 5 through 8 will automatically be connected to CM Port B.
If an application requires all remote users to have access to the same CM Port, parallel Ports A & B.
Refer to Section 7. Connections: for details of how to make these connections. Caution: When
paralleling CM Ports, you will only be able to have one CM unit connected to the DeesLink.
Passwords
Password (security code) access features of the DeesLink are the primary means to prevent unauthorized
use of the services for which this unit is being installed.
By default, access to the DeesLink requires entering a password, however this feature can be disabled
for special usage. Passwords must be a minimum of 4 digits and up to a maximum of 8 digits long. Allzeroes is not allowed (any length). Each user is assigned a unique password. Each unique Password is
what determines the accessibility of the User assigned it.
Multiple Users could be assigned the same password, but only the lower User number will be accessible.
Confidential Page 2 7/11/2014
Dees Communications Corporation Rev: 071114
Password Disable: CAUTION…ONLY ENABLE THIS FEATURE WHEN ABSOLUTELY SURE
THAT SECURITY IS NOT A REQUIREMENT FOR USER ACCESS.
The password feature can be disabled for single-user applications that don’t require this protection, (i.e.
restricted DID access).
To disable the password requirement, enter the programming mode and enter (* 0 * *).
To re-enable the password requirement, enter the programming mode and enter (* 0 * *).
CM Line Access Assignment (Restricted Dialing)
Each User can be limited to the line numbers they can dial access after being connected to their assigned
CM Port, either A or B. Line numbers 10 through 99 can be assigned.
Lower Limit Example: You want to assign a User to CM Port A, give them the password of 1234 and
allow them to access the lowest CM Line 10. The programming string up through that point would be:
* 2 * 1234 * 10. The User with this password (1234) assigned would be User 2 on CM Port A upon
accessing DeesLink and would be able to access line 10 as the lowest line available to them.
Upper Limit Example: Let’s use the same User as above and in addition we will limit their access to an
upper limit of CM Line 19. The programming string is now: * 2 * 1234 * 10 * 19.
To this point in the program string, User 2 will be limited to accessing CM Lines 10 through 19 on CM
Port A.
Through the use of assigning the upper and lower limits of the CM Line Assignments, specific access to
a range of CM lines can be given to each User.
Restricted Dialing Disable: CAUTION…DO NOT DISABLE RESTRICTED DIALING IF YOU ARE
INTERFACING WITH A DEES CALL MONITORING (CM) PRODUCT.
Restricted Dialing can be disabled for generic Remote Access applications. The ## disconnect command
is the only recognized sequence in this mode.
To disable Restricted Dialing, enter the programming mode and enter (* 9 * *).
To re-enable Restricted Dialing, enter the programming mode and enter (* 9 * *).
Time Out Period
The Time Out Period is the period of time in minutes that each User is allowed before DeesLink
automatically disconnects. This period can be programmed for each User from 1-99 minutes. If the Time
Out Period is not programmed then each User is automatically given the default period of 60 minutes.
Time Out Period Disable
In applications where the DeesLink is required to remain accessed without timing out, the Time Out
Period can be disabled. By inputting 00 as the Time Out value during the programming sequence, the
Time Out Period will be disabled for that user. If the Time Out Period is to be disabled for all users, then
each user will have to be programmed using 00 as the Time Out value.
Confidential Page 3 7/11/2014
Dees Communications Corporation Rev: 071114
CAUTION: IF THE TIME OUT PERIOD IS DISABLED, THE ONLY WAY TO RELEASE THE
DEESLINK, ONCE ACCESSED, IS BY DIALING ## BY THE USER, OR BY THE CENTRAL
OFFICE SENDING A DISCONNECT SIGNAL. IF FOR SOME REASON THE UNIT DOES NOT
RECEIVE ONE OF THESE DISCONNECT SIGNALS, THE ONLY WAY TO RELEASE THE LINE
IS BY UNPLUGGING THE DEESLINK’S POWER OR LINE CORD MOMENTARILY.
Factory Defaults
LL = 10, lowest CM line accessible
HH = 99, highest CM line accessible
TT = 60 minutes, Time Out Period
PPPP = xxxx for User 1 only (system administrator), no other passwords are assigned by default.
Feedback Tones
1 beep tone = confirmation of entering Idle mode
2 beeps tone = Ready: entering Monitoring or Programming mode
1 low beep tone = Release: follows ## disconnect command
(hi-lo, hi-lo) tone = alarm tone: invalid entry or time-out

Before beginning the Programming Process
To begin the process of programming and assigning User numbers and passwords, you should carefully
organize the number of Users you expect to have, which CM Port they need to access and exactly what
lines on that Port they need access to. With this information at hand, you can then fill out a
programming chart for each User.
There is no way of retrieving the current programming information from DeesLink.

Programming for all Users can be performed at once. Since programming is stored in non-volatile
memory the only way it can be changed is to program over it. It is not necessary to reprogram all Users,
only those you wish to change. At any point before the final digit is entered, the programming string can
be abandoned by entering #.
If an invalid programming sequence of characters is entered, DeesLink will generate an Alarm Tone (hilo, hi-lo), and allow the system administrator to begin over by entering #.
Local Programming
On the DeesLink unit there is a RJ-11 jack labeled PGM PORT for the purpose of connecting a standard
2500 type telephone to program the unit locally. Dial tone will not be present on the PGM jack.
Note that there is a 6 second inter-digit timeout period. If exceeded it will clear the entry and generate an
Alarm Tone (hi-lo, hi-lo). The procedure for local programming is as follows:
1. Come off-hook on the programming phone and dial xxxx*, you will receive 2 beeps;
2. Enter #, this puts you into the Idle Mode and you will receive 1 beep;
3. Enter *, then User number (1-8)
4. Enter * [just a separator]
5. Enter password you want to assign the User (ex. 1234)
6. Enter *
7. Enter (10-99) as the low CM Line assignment for User
8. Enter *
9. Enter (10-99) as the high CM Line assignment for User
10. Enter *
11. Enter (00-99) as the timeout period assigned for User.
12. Enter **, ends this specific User programming sequence and you will receive 1 beep tone.
Wait for beep tone before proceeding.
13. This process can be continued (steps 3 – 12) to set up all of the Users. Do not dial # between
programming for different Users.
14. After last User is programmed wait for 1 beep tone confirmation, then dial #. You will
receive 1 low beep, then the DeesLink will hang up.
EXAMPLE: User 2, CM Port A, Password 1234, Lowest CM Line access 10, Highest CM Line access
19, 15 minutes time out. After entering programming mode (xxxx*#), the programming string would be
(*2*1234*10*19*15**).
1. Off-hook on programming phone
2. Enter xxxx* 2 beep confirmation tone
3. Enter # 1 beep confirmation tone
4. Enter *2 User number 2 gives them access to CM Port A
5. Enter*1234 Assign password for User 2
6. Enter *10 defines lower Line limit
7. Enter *19 defines upper Line limit
8. Enter *15 will hang up after 15 minutes of inactivity
9. Enter ** 1 beep tone confirmation

Shorter String: When assigning each User, you can leave some or all of the default CM Line access
and Time Out settings unchanged by ending each User string with ** after the last field to be changed.
The same is also true if you are coming back later to make changes. You only need to enter new values
up to and through that point in the programming string and end there by entering **.
Note: All programming is stored in non-volatile memory, so the unit can be unplugged without losing
its programming.
Remove User: Any User can be removed by programming their password as 0000.
Remote Programming
When programming remotely, a timer will release DeesLink if it does not receive any digits within 15
seconds of answering.
To program DeesLink from a remote location (dialing in) the procedure would be:
1. Dial in to DeesLink by dialing the 7 or 10 digit number assigned.
2. DeesLink answers and returns a single beep.
3. Enter User’s 1 password (System Administrator) default xxxx*. You will receive 2 beep
tones as confirmation, and are now actually connected to CM Port A.
4. Enter #, DeesLink releases the CM Port and enters the Idle mode and returns 1 beep tone.
5. Begin with step 3 in the Local Programming section, to begin programming different Users.
6. After programming of different Users is complete, enter #. You will receive 1 low beep
indicating DeesLink is about to release the line.
7. Hang up.
4. Operation
LED indication and function
The LED on the front panel of the DeesLink is on and RED in the non-active state.
During incoming ringing the RED LED will blink. Upon detection of a valid input code and coming offhook on its CM Port, the LED will turn GREEN, and return to RED upon release of the CM Port.
During programming the RED LED will blink.
System operation and specific User accessibility is set by the system administrator and cannot be
changed by other Users: i.e. CM Port access, CM Line access, Password and Time Out Periods are all
preset during programming.
Typical Application, remotely accessing a CM-10 or CM-30 Call Monitoring system
A remote user dials the ten-digit number provided by the system administrator for accessing the
DeesLink. DeesLink answers incoming ringing during the second ringing cycle and gives a one second
acknowledgement tone to the user. After receiving the acknowledgement tone, the user will enter their
unique password (code) that has been provided to them by the system administrator, followed by a (*).
Upon acknowledging that the password is valid DeesLink will return a Ready tone (2 short beeps). The
user is now connected to either port A or port B, depending on the password used.
DeesLink does not provide dial tone to the user.
Confidential Page 6 7/11/2014
Dees Communications Corporation Rev: 071114
The user can now proceed with dialing the two-digit code representative of the line they wish to monitor
on the CM-10/CM-30. The user can move from line to line on the CM-10/CM-30 by dialing a single #
then the new two-digit number.
If a two-digit code outside the assigned range is attempted, a brief alarm tone is heard and the CM port
is hung up for two seconds to reset the CM-10/CM-30 unit. The DeesLink CM port then returns off-hook
and the Ready tone is heard.
When the monitoring session is over the user can disconnect by hanging up or dialing ##. Upon
disconnect the user will receive a single acknowledgment tone prior to DeesLink disconnecting.
Only one User can access DeesLink at a time.
5. Installation
DeesLink requires a dedicated central office line assignment. This number should be guarded carefully
and given to authorized Users only.
DeesLink provides an RJ-11 jack for easy connection to the outside line.
DeesLink comes self-contained, with its own power supply. All other connections in and out of the unit
are on RJ-11 jacks.
