Installation and Configuration 277
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.
