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 G747 Mode, the LLB4, LLB8, LLB12 and LLB16
bits have no affect in the G747 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 affect in the E3 Mode. Since ports 4, 8,
12, 16, 20, 24, and 28 are not active in the G747 Mode, the LLB20, LLB24 and LLB28 bits have no
affect in the G747 Mode.
0 = disable loopback
