2-3.2 Configure Cable Length DIP Switch Settings on T1 Cards
To configure the DIP switch settings on a T1 card:
1 Ensure that anti-static precautions are taken.
2 Make note of the orientation of the cables and disconnect them from the selected card.
3 Using a Phillips screwdriver, fully loosen the two screws located at the top and bottom of the
card.
4 Remove the T1 card by firmly pulling the two white tabs located at the top and bottom of the
card.
5 See Figure 2-7 to locate the DIP switch.
6 On T1 cards, the DIP switch setting is determined by the cable distance from the card to the
DSX-1 demarcation point. The following table provides the appropriate Port 0 and Port
1
DIP switch settings for DSX-1 demarcation points located within various cable distance
ranges
.
7 Place the card into the slot and slide in the card until it completely rests inside the slot. Push
the card firmly into place.
8 Using a Phillips screwdriver, tighten the two captive screws into the chassis through the
trunk card.
In Table 2-7, the first setting (0-133 ft.) is the default and should be
used for all T1 applications unless
connecting to a DSX-1 demarcation
point beyond 133 ft. When connecting two WAVEXpress chassis you will
always use the first setting regardless of distance (up to 600 m).
