Note: See Figure 7.3A for details on the signal flow for the status bits in the T1LBSR1 and T1LBSR2
registers.
Note: Bits that are underlined are read only; all other bits are read-write.
Bits 0 to 15 / T1 Line Loopback Command Status for Ports 1 to 16 (LLB1 to LLB16). 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. LLB1 corresponds to T1/E1 Port
1, LLB2 corresponds to T1/E1 Port 2, 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.
