Note: Bits that are underlined are read-only; all other bits are read-write.
Bits 0 to 15: T1/E1 Line Loopback Enable for Ports 1 to 16 (LLB1 to LLB16). These bits enable or disable the
T1/E1 Line Loopback (LLB). See the Block Diagrams in Section 1 for a visual description of this loopback. LLB1
corresponds to T1/E1 Port 1, LLB2 corresponds to T1/E1 Port 2, and so on. Since ports 4, 8, 12, 16, 20, 24, and 28
are not active in the G.747 mode, the LLB4, LLB8, LLB12, and LLB16 bits have no effect in the G.747 mode.
0 = disable loopback
1 = enable loopback

Bits 0 to 11: T1 Line Loopback Enable for Ports 17 to 28 (LLB17 to LLB28). These bits enable or disable the
T1 Line Loopback (LLB). See the block diagrams in Section 1 for a visual description of this loopback. LLB1
corresponds to T17 Port 17, LLB18 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 LLB20, LLB24, and LLB28 bits have no effect in the G.747 mode.
