Bits 0 to 11 / T1 Line Loopback Command Status for Ports 17 to 28 (LLB17 to LLB28). These read
only real time status bits will be set to a one when the corresponding T2 framer detects that the C3 bit is
the inverse of the C1 and C2 bits for 5 consecutive frames. These bits will be allowed to clear when the
C3 bit is not the inverse of the C1 and C2 bits for 5 consecutive frames. LLB17 corresponds to T1/E1
Port 17, LLB18 corresponds to T1/E1 Port 18, and so on. The setting of any of the bits in T1LBSR1 or
T1LBSR2 can cause a hardware interrupt to occur if the T1LB bit in the Interrupt Mask for MSR (IMSR)
is set to a one. In the E3 and G747 Modes, these bits are meaningless and should be ignored.
