Data Sheet
2.3.2
The receive PLL uses the 15.36-MHz clock to generate an internal 384-kHz signal which
is used to synchronize the PLL to the frame received from the line interface. The PLL
outputs the FSC-signal as well as the 1.536-MHz double bit clock signal and the 768-kHz
bit clock.

Data Delay between IOM and Line Interface
The lOM-interface B-channels are used to convey the two 64-kbit/s user channels in both
directions.
Only in the activated states the data is transferred transparently. In all other states logical
’1’s are transmitted to the IOM interface.
