Bits 17 to 28/T1 Diagnostic Loopback Enable for Ports 17 to 28 (DLB17 to DLB28).
These bits
enable or disable the T1 Diagnostic LoopBack (DLB). See the block diagrams in Section 1 for a visual
description of this loopback. DLB1 corresponds to T17 Port 17, DLB18 corresponds to T1 Port 18, and
so on. Since ports 17 to 28 are not active in the E3 mode, these bits have no effect in the E3 mode. Since
ports 4, 8, 12, 16, 20, 24, and 28 are not active in the G.747 Mode, the DLB20, DLB24 and DLB28 bits
have no affect in the G.747 mode. If the device is configured in Low Speed T1/E1 Port Loop Timed
mode (if LLTM bit in the MC1 register is set to a one), then only data will be looped back, the clock will
not be looped back.
0 = disable loopback
1 = enable loopback

Note:
Bits that are underlined are read-only; all other bits are read-write.
Bits 0 to 15/T1 Line Loopback Far End Activate Command for Ports 1 to 16 (LB1 to LB16).
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. LB1
corresponds to T1/E1 Port 1, LB2 corresponds to T1/E1 Port 2, 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
