Functional Description
2.3.5
IOM -2 Interface Channel Switching
In order to realize intelligent NT configurations the IPAC provides basic switching
functions. These include:
• Individual channel transfer from the selected (i.e. pin strapped) IOM-2 channel
(channel 0 or 1) to IOM-2 channel 0.
• Individual channel reversion on input and output lines.
All switching functions are controlled via the MON-8 “IOM-2 channel” register (see MON-
8 description). The following sections illustrate a variety of possible switching
combinations typical for the intelligent NT. To facilitate the description of the switching
function figure 20 illustrates a typical intelligent NT with the speech CODEC ARCOFI
combined with several terminals. Monitor programming for both ARCOFI and IPAC can
only be performed in monitor channel 1.
