PEB 22554
Functional Description E1
in a byte or bit interleaved format. Bit interleaving is valid with the 16.384 or 8.192 MHz
clocking rates. All four single channel FALCs(1-4) have to be configured equally with the
following parameters:
• clocking rate : 16.384 / 8.192 MHz ,
SIC1.SSC1/0
• data rate : 16.384 / 8.192 MBit/s, SIC1.SSD1, FMR1.SSD0
• time-slot offset programming : RC1/0 , XC1/0
• receive buffer size : SIC1.RBS1/0 = 00 (2 frames)
The multiplexed data stream is internal logically ored. Therefore the selection of the
active channel phase have to be configured different for each single channel FALC.
Programming is done with SIC2.SICS2-0.
In system interface multiplex mode signals on RDO2-4 and RSIG2-4 are undefined,
while signals on SCLKR2-4, SYPR2-4, SCLKX2-4, SYPX2-4, XDI2-4 and XSIG2-4 are
ignored.
