Connection Methods for Remote Programming
Conditions
Only one system programming session is permitted at a time. Access will be denied to a second party 
who tries to perform system programming, including system programming via a PT.
System programming can be performed either in interactive or batch mode.
System Password
 
To access system programming in interactive mode, a valid password must be entered. The password 
is set at the factory but can be changed through system programming (
System Password [002]). 
A user can upload system programming data from a PC to the PBX or download it from the PBX to a 
PC.
If communications between the PBX and PC fail before completing Firmware Upgrade or system 
programming data upload from a PC to the PBX, the successfully transferred portion of the data can 
still be used.
Firmware Upgrade can be performed only through on-site programming using Serial Interface (RS-
232C port) or USB.
