Functional Description
The bursts are allocated to consecutive time slots in a frame by the static inputs X0 (TS0), X1 (TS1),
X2 (TS2).
Table 2
indicates the allocations.
Figure 11
gives the positions of the respective frames.
Figure 10
Timing of Data and Clocks of IOM
in the Inverted Mux Mode
IOM
-2 Mode
Timing mode applicable in LT-T and LT-S modes: 4096 kHz.
As opposed to inverted mode, data change with rising edges and frame synchronization is defined
as in IOM-1 mode. (cf. IOM
Interface Specification, Rev. 2.2).
