The IOM
Guide [13].
2.2.1
The IOM
indicates the start of an IOM
transfer on both data lines DU and DD. The DCL is twice the bit rate. The bits are shifted
out with the rising edge of the first DCL clock cycle.
Note: It is not possible to write any data via IOM
The IOM
The FSC signal is an 8 kHz frame sync signal. The number of PCM timeslots on the
transmit line is determined by the frequency of the DCL clock, with the 512 kHz clock 1
channel consisting of 4 timeslots is available.
IOM
The frame structure on the IOM
clock of 512 kHz is shown in
•
Figure 4
The frame is composed of one channel:
Channel 0 contains 144-kbit/s of user and signaling data (2B + D), a MONITOR
programming channel (not available in Q-SMINT
(CI0) for control of e.g. the U-transceiver.

-2 Frame Structure of the Q-SMINT
-2 interface consists of four lines: FSC, DCL, DD, DU. The rising edge of FSC
-2 interface always operates in NT mode according to the IOM
-2 interface can be enabled/disabled with pin DIO.
