Notes

POS is an acronym for Board Position. This has also been referred to as the Equipment Location(EQL) and the Physical Slot Number in previous documentation.

These numbers appear etched or silkscreened on the wiring side of the backplanes. They are not the same as the slot numbers on the front carrier label!

The assembly comcode for the backplane has been included because backplane and carrier marking over the years has been inconsistent; the comcode appears etched or silkscreened on the wiring side of most backplanes.

-150V is the voltage for TN769's & TN746's that are powering neon lamps in analog message waiting phones.

Test V means Test Backplane/Carrier Voltages. Previously all the POS 01 power supplies provided test points for the different DC voltages on the backplane. The TN2036 provides that functionality.
