Introduction 
This section is devoted to an explanation of the implementation and operation of TransTel electronic 
telephones (keysets). Included are normal functions that are available to most station users and 
functions that are available only to console operators. 
1A2 Emulation / Privacy Release 
This feature allows station users to join a conversation in progress with outside lines and other station 
users. A station user must have a class of service option enabled in order to join a call in progress. You 
may temporarily invoke privacy to reject others attempts to join your conversation, if desired, through the 
use of a 1A2 (privacy release) key. This feature may be activated on all lines, or only specific lines as
