MON-8 IOM -2 Channel Register
The features accessible via the IOM-2 Channel register allow to implement simple
switching functions. These make the IPAC the ideal device for intelligent NT
applications. Please refer also to the section “IOM-2 channel switching”. Two types of
manipulation are possible: the transfer from the pin-strapped IOM-2 channel (0 … 7) into
IOM-2 channel 0 and a change of the B1, B2 and D data source.

Transfers the B1 channel from its pin-strapped location into IOM-2
channel 0.
Direction of the B1 channel. The normal direction (input/output) of DU and
DD depends on the mode and is shown in table 30 below. By setting B1D
the direction for the B1 data channel is inverted.
Transfers the B2 channel from its pin-strapped location into IOM-2
channel 0.
Direction of the B2 channel. The normal direction (input/output) of DU and
DD depends on the mode and is shown in table 30 below. By setting B2D
the direction for the B2 data channel is inverted.
Transfers the D-channel from its pin-strapped location into IOM-2 channel 0.
C/I Channel location: The timeslot position of the C/I Channel can be
programmed as “normal“ (LT-S and LT-T modes: pin strapped IOM-2
channel, TE mode: IOM-2 channel 0) or “fixed“ to IOM-2 channel 0
(regardless the selected mode).
C/I Channel handling: Normally the C/I commands are read from the pin-
strapped IOM-2 channel. With this bit programmed C/I channel access is
only possible via the SM/CI register.
