2.3 System Data Control
298 Feature Guide
2. Remote Programming:
Conditions
• Access to system programming is allowed only one at a time.
• Programmer Code and Password for System Programming
To access system programming, a programmer code and its password must be entered.
There are three programmer codes, which are set at the factory. Each programmer code
has a unique password which is also set at the factory.
Programmer codes can be changed using the Maintenance Console, by selecting
"Programmer Code Change" from the "Tool" menu. Passwords can be changed through
system programming. If the wrong password is entered a preprogrammed number of times
(Default: None [no limitation]) remotely, access will be locked and can only be unlocked by
enabling remote access through system programming ( Remote Programming [810]).
Method Description
Using a modem
(RMT card)
An RMT card must be installed. The floating extension number of
the analogue remote maintenance must be assigned ( Modem
Floating Extension Number [811]).
PC programming, using a telephone connected in parallel with the
modem, can be done in the following ways:
• Direct Access
Dial the DIL/DID/DDI number whose destination is the floating
extension number of the analogue remote maintenance.
• Through DISA
Dial the floating extension number of the analogue remote
maintenance using the DISA feature. ( 1.16.6 Direct Inward
System Access (DISA))
• Call Transfer
Call an extension (probably the operator), and request a
transfer to the floating extension number of the analogue
remote maintenance. ( 1.11.1 Call Transfer)
Using an
external modem
(Not RMT card)
An external modem can be used instead of an RMT card to perform
the remote programming. An external modem can be connected to
the Serial Interface (RS-232C) of the PBX. Connect the modem to
an extension port which is assigned as the DIL/DID/DDI/MSN
destination or to a trunk directly to connect to the PBX from the PC.
An AT command can be sent to the modem automatically when it
is connected to the Serial Interface (RS-232C) port. AT commands
can be programmed beforehand through system programming to
initialise the modem. An AT command can also be sent manually in
the PT system programming mode ( External Modem Control
[801]).
Using an ISDN
TA interface (64
kbps) through
an ISDN Trunk
The floating extension number of the ISDN remote maintenance
must be assigned ( ISDN Remote Floating Extension Number
[812]), and dial the DIL/DID/DDI/MSN number whose destination is
the floating extension number of the ISDN remote maintenance.
The RMT card is not required for this method.
This method is available only when an user-supplied ISDN TA that
supports CAPI is used.
