Method Description Required
Hardware
Off-site modem Call the PBX and have the call directed to the floating extension
number (default: 599) assigned to the analog remote
maintenance feature using one of the following methods:
Direct Access: Using the off-site modem, dial a telephone
number with the modem which will direct your call (via Direct In
Line (DIL) or Direct Inward Dialing (DID) distribution) to the
floating extension number assigned to the analog remote
maintenance feature.
DISA: Using a telephone, dial a telephone number which will
direct your call (via DIL or DID distribution) to a floating extension
number used by the Direct Inward System Access (DISA)
feature (® 4.1.7 DISA (Direct Inward System Access)). Next,
dial the floating extension number assigned to the analog
remote maintenance feature. Then access the PBX with the
modem.
Call Transfer: Using a telephone, dial a telephone number
which will direct your call to an operator (or other extension of
the PBX) and request to be transferred to the floating extension
number assigned to the analog remote maintenance feature
(® 3.1.8 Call Transfer). Then access the PBX with the modem.

user-supplied
modem
On-site modem The modem is connected to the Serial Interface (RS-232C port)
and also to either an extension port which is assigned as the
DIL/DID destination, or to a CO line directly. AT commands can
be sent to the modem automatically when it is connected to the
Serial Interface (RS-232C port) and can be programmed
beforehand, through system programming, to initialize the
modem. AT commands can also be sent manually in the PT
system programming mode.

Conditions
•Only one system programming session is permitted at a time. Access will be denied when a second party
tries to perform system programming, including system programming via a PT.
•Programmer Code and Password for System Programming
To access system programming, a programmer code and its password must be entered. For more details,
see Section 13.1.3 Password Security.
•Remote Programming Limitation
It is possible to disable remote access through system programming. Disabling this feature will also disable
the ability to perform on-site programming via modem.
