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.
