Procedure 14.15: CONVERT CI (UN71B) TO CI2 (UN71C) - 5E11 AND LATER
OVERVIEW
This procedure supports the replacement and conversion of the control interface (CI) circuit pack, UN71B, to the
control interface model 2 (CI2) circuit pack, UN71C. The CI2 provides, through peripheral interface control buses
(PICB), communication between the switching module processor (SMP) and peripheral units. The CI2 provides, in
addition to CI functionality, the ability to pump peripheral units in parallel. And, because of its improved scanning
mechanism, it may slightly enhance switching module (SM) performance.
