Extract Register B
Simple switching (BID=0)
The Extract Register B receives the contents of the Insert Register A
Bidirectional switching (BID=1)
The Extract Register B receives the contents of the Insert Register A
AND
The Extract Register A receives the contents of the Insert Register B

Simple switching (BID=0)
The output PCM 1-TS 7 receives the contents of the input PCM 1-TS 21
This is a loopback
Bidirectional switching (BID=1)
The output PCM 1-TS 7 receives the contents of the input PCM 1-TS21
AND
The output PCM 1-TS 21receives the contents of the input PCM 1-TS 7
Two loopbacks are established
