<h5 id="rzahjusercos">User Class-of-Service with Inactive Transmission Groups RSCV</h5>
<p>This structure is used to represent an RSCV that allows inactive transmission
groups. It has the same class-of-service characteristics as the class-of-service
that is given by the user.</p>
<p>BIND, RSP(BIND), and other RUs carry the route selection control vector
(RSCV) . It describes the path through an APPN network that a session is to
take or has taken. APPN nodes send and receive the RSCV , but LEN nodes do
not.</p>
