Daisy-Chaining to MMI

If two or more Lineside T1 cards are installed and the MMI is used,
daisy-chain the cards together to use one MMI terminal or modem, See

Figure 37 "Lineside T1 card - connecting two or more cards to the MMI"
(page 209)

. Make the selection for this dip switch position based on how

many Lineside T1 cards are installed.

MMI Master or Slave

This setting is used only if daisy-chaining the cards to the MMI terminal or
modem. This setting determines whether this card is a master or a slave in
the MMI daisy-chain. Select the master setting if this card is the card that
is cabled directly into the MMI terminal or modem; select the slave setting
if this card is cabled to another Lineside T1 card in a daisy chain.
