Parameter Code

Value Range 4-10 digits consisting of 0-9
Description/Function Specifies the User Codes for DISA/TIE feature.
Warning for the Direct Inward System Access Users
When you enable the CO-to-CO Line Call feature of Direct
Inward System Access (DISA) function , if a third party discovers
the password (a DISA User Code) of the system, you have a risk
that they will make illegal phone calls using your telephone line,
and the cost may be charged to your account.
In order to avoid this problem, we strongly recommend the
following points:
1: Carefully maintain the secrecy of the password.
2: Specify a complicated password as long and random as you
can make it.
3: Change the password frequently.
Notes
• DISA user code is required when the DISA caller attempts to
make an outside call (Trunk Security mode) or to make either
extension or outside call (All Security mode).
• If "TIE-to-CO Security Mode" in Section "4.2 Trunk Line"
is set to "Yes," entering TIE user code is required when the
TIE caller attempts to make a CO call.
• If the entire code, for example "1234" is included in another
code, for example "12345," it is not valid.
