WIP All Call functions are enabled at SID 20 and 50, which need to be received on
WIPs at SIDs 20, 50, 21 and 22.
The MECP, SID 50, also receives BGM and Paging audio that needs to be sent over
the fibre network to the amp racks, SIDs 21 and 22. A 2nd VIF and ATA combination
will be required at each of these QE20s to send and receive this audio.
The fibre ring is allocated an Audio Bus Segment number 1 and the copper
connection is allocated segment 2.
This table shows the questions and answers required by QE20Cost so that the
correct panel designs can be done and the quantity of VIFs, ATAs and PIBs
calculated.
