A. Introduction
Introduction
This section describes a backup procedure of
system programming data from a remote
location.
To execute system programming, diagnosis, data
backup, and traffic measurement in an interactive
format via CO line from a remote location, RMT
card (Modem) must be installed to the system.
Backup (Save and Load) from a remote location
is possible only in Dumb mode.
For further information about switching of the
operating modes, please refer to Section 17-B
"Backup Utility Types".
The following conditions are required for remote
operation.
• To have successful data communications with
protocol, the communication parameters of
both the system and remote maintenance
terminal must be preset to the following fixed
values.
data = 8 bit
parity = none
stop = 1 bit
* These fixed communication parameters do
not apply to the data communication without
protocol.
• For remote access, a data terminal and modem
are required at a remote location.
For further information about communication
parameters, refer to Section 10-D-7.00
"Communication Interface".
• RMT card (Modem) must be installed to the
system.
• To administer the system from a remote
location, assign "System-Operation" "Remote
Directory Number" in system programming.
• Backup (Save and Load) from a remote
location is possible only in Dumb mode.
(When system administration from a remote
location is started, the system defaults to Dumb
operation mode.)
For further information about remote operation,
refer to Section 15-B-2.00 "System
Administration from a Remote Location".
Backup Types
There are following two backup types.
1. Save (Main Unit
• Saving the system programming data from
the system to remote terminal is possible
during on-line communication mode only.
2. Load (Remote terminal
• When loading the system programming data
from a remote terminal begins, the system
automatically shifts to off-line mode while
holding the speech path.
