The sum of ringer equivalence numbers for all devices connected to the

Security Information
Passwords
Password (security code) access to the M-106E are the primary means to
prevent unauthorized use of the services for which this unit is being installed.
Password Tips
1. Use long passwords—the longer the password, the more secure the system.
2. Change passwords—change them at least twice a year, and change the
length along with the digits.
3. Use multiple passwords—if one password has been broken, it can be
changed without impacting all users. Vary the length of passwords assigned to
different users.
4. Never disseminate the programming password (User ID number 1).
5. Monitor system usage daily and watch for excess traffic over the normal
amount of calling. The call records provided by the M-106E provide a
call-by-call and user-by-user (User ID number) listing.
6. Avoid using numbers that can be guessed by association, such as personal
or company telephone numbers, addresses, names, or vanity license plates
(names associated with numerals on pushbutton phone keypads; for example,
“NAMES” = 62637).
Restrict Codes
The restrict code feature provides a means to allow different levels of user
privileges based on the restrict codes assigned to different passwords.
The restrict code feature provides limited protection against abuse of calling
privileges. While some devices are better than others, virtually all devices of
this nature can ultimately be fooled into allowing certain calls which you want
to restrict.
The M-106E cannot restrict calls when dial tone is heard on its outgoing side,
as may be the case when the called party hangs up. The M-106E checks the
first digits dialed by the user on initial access, after a retrial (**), and after a
switchhook flash (*#). When it determines that the dialed digits cannot match
the assigned restrict codes, the call is allowed. If the caller dials a string of
digits that matches an assigned restrict code, the M-106E will disconnect both
incoming and outgoing lines.
