Begin the installation and configuration of the Lineside T1 card by selecting
the proper dip switch settings for the environment. The Lineside T1 card
contains two dip switches, each containing eight switch positions. They are
located in the upper right corner of the motherboard circuit card as shown
in Figure 32 "Lineside T1 card - T1 protocol dip switch locations" (page
186). The settings for these switches are shown in Table 77 "Lineside T1
card-T1 Switch 1 (S1) dip switch settings" (page 188) through Table 80
"Lineside T1 card - CPE or CSU distance dip switch settings (Switch S2,
positions 3 - 5)" (page 190).
When the Lineside T1 card is oriented as shown in Figure 32 "Lineside
T1 card - T1 protocol dip switch locations" (page 186), the dip switches
are ON when they are up, and OFF when they are down. The dip switch
settings configure the card for the following parameters:
