DS1 input/output cards
The ABM shelf houses the input/output (I/O) cards for connection of DS3,
DS1, access test cards for PGTC and the test bus access. Each DS1 mapper
card in the ABM shelf requires two I/O shelf positions: one for a DS1 input
card and one for a DS1 output card.
The DS1 protection mapper card requires a DS1 protection bridge card to be
placed in the I/O shelf.
The dual power filter cards are mounted in the far right-hand end of the shelf
for connection to the BIP. See Figure 13-19 on page 13-29 for the wiring
connection location to the BIP.
The DS1 input I/O card connection wiring diagram is shown in Figure 13-36.
