Note: Bits that are underlined are read-only; all other bits are read-write.
Bits 17 to 28: T1 Line Loopback Far End Activate Command for Ports 17 to 28 (LB17 to LB28). These bits
cause the appropriate T2 transmit formatter to generate a Line Loopback command for the far end. When this bit is
set high, the T2 transmit formatter will force the C3 bit to be the inverse of the C1 and C2 bits. The T2 transmit
formatter will continue to force the C3 bit to be the inverse of the C1 and C2 bits as long as this bit is held high.
When this bit is set low, C3 will match the C1 and C2 bits. LB17 corresponds to T1/E1 Port 17, L18 corresponds to
T1/E1 Port 18, and so on. These bits are meaningless in the E3 and G.747 modes and should be set to 0.
0 = do not generate the line loopback command by inverting the C3 bit
1 = generate the line loopback command by inverting the C3 bit
