Removing Quad Modem Cards

Occasionally it may be necessary to remove quad modem cards from
the Remote Annex (for example, if a quad modem card fails and needs
to be replaced). On the Modem Module, there are eight locations that
can accommodate quad modem cards (up to 32 modems). These
locations are numbered (1-4, 5-8, 9-12, and so on). When the Remote
Annex encounters an empty location, it assumes that the modem card
before the empty location is the last modem card in the series.
Therefore, any empty location resulting from the removal of a quad
modem card wil be interpreted as an indicator that the last modem
card has been reached. Any quad modem cards installed after the
empty location will not be recognized, unless the DIP switch section
corresponding to the removed modem card is toggled ON.
Table C-1 provides a map of the quad modem card locations and their
corresponding DIP Switch assignments.
