5.1.1.2
In E1 mode (Pin E1/T1 = 1) there are 32 channels numbered from 0 to 31. The channels
are directly mapped into the corresponding 32 frame slots.
5.1.2
The Generic Interface Mode (GIM) makes the framer interface more universal, so that
other framer/line interface units or T1/E1 transceivers can be connected directly to the
IWE8. Depending on the E1/T1 pin, the interface can be adopted to line bit rates of
1.544 MHz (T1 rate) or 2.048 MHz (E1 rate). The mode is enabled by setting bit om =
01
when switching to GIM (FTCKOi has to be disconnected to ensure proper port function).
