Daisy-Chaining to MMI
If two or more LEIs are installed and the MMI used, daisy-chain the cards
together to use one MMI terminal or modem. Make the selection for this dip
switch position based on how many LEIs are being installed.
MMI Master or Slave
This setting is used only if daisy-chaining the cards to the MMI terminal or
modem. It determines whether this card is a master or a slave in the daisy
chain. Select the master setting if there are no LEIs between this card and
the MMI terminal or modem. Select the slave setting if there are other cards
in the daisy chain between this card and the MMI.
Table 115 "LEI card - Switch 1 dip switch settings" (page 277) through Table
117 "LEI card - XPEC address dip switch settings (Switch S1, positions
3-6)" (page 278) show the dip switch settings for Switch 1. Table 118 "LEI
card - E1 Switch 2 (S2) dip switch settings" (page 279) shows the dip switch
settings for Switch 2.
