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.
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) describe the proper dip
switch settings for each type of T1 link. After the card has been installed, the
MMI displays the DIP switch settings the command Display Configuration
is used. See "Functional description" (page 391) for details on how to
invoke this command.
