Data Sheet
2.2.3.1
The two strobe signals can be generated with every 8-kHz frame and are controlled by
the registers SDS1/2_CR. By programming the TSS bits and three enable bits
(ENS_TSS, ENS_TSS+1, ENS_TSS+3) a data strobe can be generated for the IOM-2
time slots TS, TS+1 and TS+3 and any combination of them.
The data strobes for TS and TS+1 are always 8 bits long (bit7 to bit0) whereas the data
strobe for TS+3 is always 2 bits long (bit7, bit6).
Figure 20 shows three examples for the generation of a strobe signal. In example 1 the
SDS is active during channel B2 on IOM-2 whereas in the second example during IC1
and IC2. The third example shows a strobe signal for 2B+D channels which is used e.g.
at an IDSL (144kbit/s) transmission.
