map

This T-1 parameter controls the mapping of the modems to the T1 Drop
and Insert Interface (T1DII) and the T1 Network Interface (T1NI) DS0
slots/channels. The modems can be mapped to any unoccupied slot on the
T1NI or the T1DII. The T1NI and the T1DII can be mapped to each other
on channels that are not occupied by modems. Information flowing
between the T1NI and a modem and the T1DII and a modem flows as
voice, not data. Table 4-6

lists the options that are used with the map

parameter.
