Each SICOFI-4 device must be assigned to its individual IOM-2 channels by pin-
strapping. The SICOFI-4 coefficients (filter characteristics, gain, … ) as well as other
operation parameters, are programmed via the ELIC over the IOM-2 monitor channel.
Example
Initializing 4 consecutive CFI timeslots as an analog IOM-2 channel.
Timeslots 0, 1, 2, and 3 of CFI port 2 shall represent the IOM channel 0 of port 2.
Timeslots 4, 5, 6, and 7 of CFI port 2 shall represent the IOM channel 1 of port 2. This
requires the SICOFI-4 to be pin-strapped to that slot by connecting pin TSS0 and pin
TSS1 to 0 V.
Timeslots 4 and 5 represent the two B channels that may for example be switched to the
PCM interface. Timeslots 6 and 7 represent the monitor and signaling (SIG) channels
and must be initialized in the ELIC control memory (CM):
W: MADR = FF
W:MAAR
W: MACR = 7A
W: MADR = FF
W: MAAR = 1D
W: MACR = 7B
W: MADR = FF
W: MAAR = 9C
W: MACR = 7A
W: MADR = FF
W: MAAR = 9D
W: MACR = 7A
The above steps have to be repeated for all timeslots that shall be handled by the
monitor or signaling handler of the ELIC (i.e. TS2 and TS3, TS10 and TS11, TS14
and TS15).
