The “.CUS” Files
If only one of the commands, SilenceLevel, or SilenceDuration, is given and the 
parameter is OFF, then pause deletion will be inactive. Likewise if one of the two 
commands is given and the parameter is ON then pause deletion will be active, and will 
use the standard values of 240 for SilenceLevel and 6 for SilenceDuration. If either 
command follows any Silence command and has an ON or OFF parameter, it will override 
the preceding Silence command.
 SILENCELEVEL 245 ; ADPCM only, set pause deletion threshold level
 SILENCEDURATION 7 ; ADPCM only, set pause deletion trigger time
 SILENCELEVEL OFF ; ADPCM only, disable pause deletion
 SILENCEDURATION ON ; ADPCM only, enable pause deletion using
 ; standard values
SpeakTime
The SpeakTime command controls use of the DisplaySaver TimeStamp option, and only 
applies if your system has that option as part of its PageSaver features. Setting to 
MANUAL, the default, means people must press the 8 key to hear the time that a message 
came in. Setting to BEFORE means no user action is required, it will always play the time 
before playing the mailbox message; AFTER will always play the time after playing the 
mailbox message. NONE disables the feature (but numeric display insurance still works). 
SysLogs
The SysLogs command is useful on extremely large and busy systems. Normally, there are 
20 log files, named LOG00 through LOG19; each is 20K in length. LOG00 is filled up 
first, then LOG01, etc.; when LOG19 fills, it starts over with LOG00 again, writing over 
its previous contents. On most systems, these log files give a week or two of history, 
useful for troubleshooting and analysis. On really busy systems, they might last less than a 
day. This command allows increasing the number or size of the files in these situations. 
However, be careful - if you set them too large, you can run out of disk space, messing up 
paging. 
It is recommended that: 
SIZE times NUMBER be less than 2 megabytes as a general rule. 
SIZE can be 1 to 500,000 (for 300d2 & later it is 1900 to 65,000); 
NUMBER can be 2 to 100. Do not set size to greater than 64,000 
(due to segment limits).
 SYSLOGS SIZE 30000 ; make each log a little bigger
 SYSLOGS NUMBER 30 ; more logs than standard 20
 SYSLOGS SIZE 40000 NUMBER 30 ; bigger logs and more of them
TotalPCM
The TotalPCM command is for systems with all Rev E or newer dual trunks and a lot of 
trunk routing. It allows a second PCM highway to be used, which increases the system 
capacity from 24 speech paths to 48 speech paths. 
The format of the command is:
 TOTALPCM X
“X” is 24 or 48. The default is 24; thus, only the form shown here is needed.
