800.2 REMOTE MAINTENANCE 
C. Maintenance Password _ 
A. General Overview 
The Remote Maintenance feature allows authorized 
personnel to survey system and slot configuration 
information. This can be done through a modem or 
data terminal connected to the system CPB via the 
RS232C port. The commands are entered from a 
keyboard and are limited to those listed. 
8. Overview of Maintenance Commands 
There are four (4) basic commands available in the 
Remote Maintenance feature. All commands begin 
with a single character, followed by a space, another 
character and an optional diiil or digits. All com- 
mands are terminated with a carriage return. 
Basic format of the commands are shown in Figure 
800-l : The Remote Maintenance feature, like Remote 
Programming, is entered via a six-character al- 
phanumeric string. The password prompt is given by 
entering a carriage return at the device connected to 
the CCU RS232C port. After the prompt is printed 
out, the password should be entered followed by a 
carriage return. Proper entry of the password will 
resutt in the maintenance prompt. The Remote Main- 
tenance password is: {BRANDY} 
D. Exit Maintenance 
The Exit command will terminate the current Remote 
Maintenance feature session. The Exit command 
format is: MAINT>X 
maint>? 
command list: d sCnn1 - dwnp system or slot configuration data

no parameter indicates that the entire system will be dumped
