Slot Pin Assignments
Loop 1 connects to the Tip and Ring leads. Loop 2 connects to the Tip 1 and Ring 1 leads. To locate the appropriate
connector, see the pin assignment representations in
If the Loop 1 and Loop 2 leads are reversed in 4-wire applications, a CHREV (Channels
Reversed) message appears in the ALARMS display field of the HiGain status screen. This
condition does not affect system operation, but should be corrected to avoid any confusion
regarding the identities of the two HDSL loops.
