• Manufacturer Part Number: peb20525
• Description: 2 Channel Serial Optimized Communication Controller For Hdlc/ppp
• Manufacturer: Infineon Technologies Corporation

Note: If time-slot 0 is to be selected, the DELAY has to be as long as the PCM frame
Note: In extended transparent mode the width xCC of the selected time-slot has to be

itself to achieve synchronization (at least for the 2nd and subsequent PCM
frames): DELAY = PCM frame length = 1 + xTSN*8 + xCS. xTSN and xCS have
to be set appropriately.
Example: Time-slot 0 in E1 (2.048 Mbit/s) system has to be selected.
PCM frame length is 256 clocks. 256 = 1+ xTSN*8 + xCS. => xTSN = 31, xCS = 7.
n ´ 8 bit because of character synchronization (byte alignment). In all other modes
the width can be used to define windows down to a minimum length of one bit.
