With the Cortex, we wanted to give users the opportunity of making their telephone login as simple or as complex as they wanted. Plus, we combined the username and password into a single entry string (which we called the ID). This string can be as short as 3 characters, but as long as 32 characters, thus letting users adapt their logon to their own needs and security tolerances. This Phone ID is a separate string from the on-line User Name and Password.
Telephone users are configured in the Users section of the System Drop-Down Menu:
The Telephone login Credentials are entered into the ID (Phone) field in the right part of the window shown above.
They can be between 3 and 32 characters long on a phone keypad.
To access your Cortex, dial-in and upon hearing the Voice prompt, enter your Credentials. Section 1 below lists the commands that can then be entered.
Note that after 3 failed login attempts, the Cortex will hang up and the connecting user will have to dial-in once again. This hampers any brute force hacking attempt by an auto dialer.
After 4 failed attempts, the Cortex automatically raises its 1W1 flag, thereby indicating a potential hacking event. This flag can then be used with a Virtual Logic Gate to send an alarm to your NOC or to the (real) site engineer (by all the usual means such as email, dial-up voice, text message etc.).
Note also that the default user credentials are present in the units when they leave the factory.
- Operator = 8 x the number 6 (which is O)
- Administrator = 8 x number 2 (which is A)
- Supervisor = 8 x number 7 (which is S)
- Director = 66248239 (which represents MOCIVAD9)
These default users should all be changed when the unit is initially set up

DTMF Group Commands and Quick Commands
These DTMF Commands allow you to execute one or many actions using your telephone keypad.
They have to be pre-configured in the Cortex System drop-down menu as shown below:
DTMF Group Commands
Group commands are a way to have a Cortex execute one or many actions (or commands) using any of 3 dedicated telephone keypad digits: 1, 7 and 9. A typical use could be to Raise RF Power (1), Lower RF Power (7) and Read RF Power (9), among many other possible applications.
29 groups of 3 digits are possible (commands 50 to 79).
To use this feature, you must first configure them in your Cortex. From the main System menu, select DTMF Group Commands. Then, either add a new group by clicking the “+” icon, or edit a previously created group by selecting the group and clicking the edit icon as shown below.
At the top of the configuration window, select the group ID number you want to configure (from 50 to 79).
Then, in the same window, for each of the empty fields available (1, 7 and 9), enter the command(s) you want. Note that there can be more than one command. You can enter the commands manually or use the drop-down menus to create them.
To use a Group Command with a Cortex, once you have logged-in by telephone and hear the «Ready for command» audio prompt, press the Group ID of your choice (from 50 to 79) followed by # (Enter). This puts you into the Group Command mode and gives you access to the specific 1, 7 and 9 digit commands associated with this group ID. Then use the 1, 7 and 9 keys to execute the commands you want and repeat (only the 1, 7 and 9) as many times as necessary. To exit this mode, press #.
DTMF Quick Commands
Ten possible selections are possible, each numbered 0 to 9 (keypad digits).
To use this feature, you must first configure them in your Cortex. From the main System menu, select DTMF Quick Commands. Then, either add a new quick command by clicking the “+” icon, or edit a previously created command by selecting it and clicking the edit icon as shown below.
At the top, select the keypad digit you want to configure.
Then, using the different drop-down lists, select the proper command type, slave number, input type and I/O number. Configuration is now complete.
To use a Quick Command with a Cortex, once you have logged-in by telephone, and hear the «Ready for command» audio prompt, press the digit you want in order to do the programmed actions, and then press # (“Enter”). The whole sequence is executed once. To re-execute the command, re-enter the single-digit code and press #.
