Priority Lines Feature on TWOx12 

 

26 March, 2002 

 

 
 
We are happy to announce the addition of a “Priority Lines” feature to the TWOx12. This feature is 
supported on version 1.06 and later. NOTE: A more flexible version of this feature is available in Software 
version 3.0 and later, and is configure from the Desktop Director. For Details on this, and other 3.0 features 
see the TWOx12 Manual version 2.0 available here: 

http://www.telos-systems.com/support/manuals.htm

  

 
For information on upgrading the software in your TWOx12 please visit the following URL: 

http://www.telos-systems.com/support/software.htm

  

 

How it works: 

 
Designating one or more pairs of lines as “Priority Lines” will have two effects on how those lines operate: 
 
1. 

Priority lines are not locked out when the “Block All” function is used. 

 
2. 

When ringing, priority lines activate a “Priority Ring Out” output on the rear of the TWOx12. 

 
The following revised pinout chart should be used in place of the chart shown in Section 2.9 of the 
TWOx12 version 1.0 manual:
