5.15 Plug-In Interface Cards (PIICs)
If the customer orders a unit configured for use with PIICs (Figure 5-4), greater flexibility for
changing and upgrading the terrestrial interface will be available. Each of the interfaces
described below consists of a single card with a metal back plate. Each interface can be plugged
into one of three slots on the rear of the unit.
Figure 5-4. Typical PIIC
To insert the PIIC, slide the card completely into the appropriate slot (1, 2, or 3) ensuring that it
lines up with the alignment slots. When the PIIC is fully seated, tighten the two screws hand tight.
5.15.1 ASI PIIC
This interface supports two terrestrial interface types.
