• Manufacturer Part Number: PEB20534H-10
• Description: DMA Supported Serial Communication Controller with 4 Channels DSCC4
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

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
the width can be used to define windows down to a minimum length of one bit.
8 bit because of character synchronization (byte alignment). In all other modes
