Line supervision on T1 failure
This setting determines in what state all 24 ports of the Lineside T1 card appears to the CS
1000M, CS 1000E and Meridian 1in case of T1 failure. Ports can appear as either in the on-
hook or off-hook states on T1 failure.
Note:
All idle Lineside T1 lines go off-hook and seize a Digitone Receiver when the off-hook line
processing is invoked on T1 failure. This may prevent DID trunks from receiving incoming
calls until the Lineside T1 lines time-out and release the DTRs.
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 31: Lineside T1 card - connecting two
on page 170. 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.
