AD1 – selects address of local unit for loopback
AD2 – selects address of next unit downstream for loopback
AD3 – selects address of second unit downstream for loopback
AD4 – selects address of third unit downstream for loopback
AD5 – selects address of fourth unit downstream for loopback
AD6 – selects address of fifth unit downstream for loopback
LPBK – forces this unit to set up bidirectional loopback for selected B1 or B2 channel
CRTX – sets up loopback toward carrier
SW1-6: Zero Byte Substitution (ZBS)
Enables or disables ZBS
I
Note: ZBS must be set the same for the COT and RT. For AMI-provisioned carriers,
ZBS should be enabled. Setting is optional for B8ZS-provisioned carriers.
LPTX – sets up loopback toward the loop
NT1 – selects address of the NT1 for loopback
