Function
HDSL1
Tip and Ring terminations for HDSL Pair #1 from the COT. -130 Vdc is simplexed on this line for
powering the RT.
HDSL2
Tip and Ring terminations for HDSL Pair #2 from the COT. +130 Vdc is simplexed on this line for
powering the RT.
BYPASS
Tip and Ring terminations for the metallic bypass pair to the COT.
PWR 1A
Termination for auxiliary power pairs when using a doubler unit. Note: This line is simplexed with
+130 Vdc for powering the RT.
PWR 2A
Termination for auxiliary power pairs when using a PG-Flex doubler unit. Note: This line is
simplexed with -130Vdc for powering the RT.
PWR 1B
Termination for auxiliary power pairs when using two doubler units. This line is simplexed with
+130Vdc for powering the RT.
PWR 2B
Termination for auxiliary power pairs when using two doubler units. This line is simplexed with
-130Vdc for powering the RT.
