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 33 "Lineside T1 card - T1 protocol dip switch locations" (page
195). The settings for these switches are shown in Table 91 "Lineside T1
card-T1 Switch 1 (S1) dip switch settings" (page 197) through Table 94
"Lineside T1 card - CPE or CSU distance dip switch settings (Switch S2,
positions 3 - 5)" (page 198).
When the Lineside T1 card is oriented as shown in Figure 33 "Lineside T1
card - T1 protocol dip switch locations" (page 195), 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:
MMI port speed selection
This dip switch setting selects the appropriate baud rate for the terminal or
