188 NT5D11 and NT5D14 Lineside T1 Interface cards
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.
Table 77 "Lineside T1 card-T1 Switch 1 (S1) dip switch settings" (page
188)
through Table 80 "Lineside T1 card - CPE or CSU distance dip
switch settings (Switch S2, positions 3 - 5)" (page 190) 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 385) for details
on how to invoke this command.
