PCM mode 0, double rate clock (4 MHz, 2 Mbit/s), PFS
evaluated with falling edge of PDC
256 bits per PCM frame
with BPF = 256, the internal PFS marks downstream bit
number (BND) 2; for detail, refer to the Application
Hints, figure 62
the internal PFS marks upstream bit number (BNU) 2; for
detail, refer to the Application Hints, figure 62
no clock shift; PCM data sampled with falling, transmitted
with rising PDC
PDC and PFS used as clock and framing source for the CFI;
CRCL = PDC; prescaler divisor = 1; CFI mode 0
FSC shaped for IOM 2 interface; DCL = 2 x data rate;
CFI data received with falling, transmitted with rising CRCL
256 bits per CFI frame
PFS is to mark CFI time slot 0
PFS is to mark bit 7 of CFI time slot 0; no shift of CFI
upstream data relative to CFI downstream data
2 bit channels located in positions 7, 6 on all CFI ports
transparent mode 0; continuous frame transmission
switched ON; HDLC receiver active; test loop disabled
power up; point-to-point configuration. IDLE sequences as
interframe output; double rate data clock; clock mode 3
Receive Message Complete (RMC); Reset HDLC Receiver
(RHR); Transmitter Reset (XRES)
transmit pool ready
network (as for W&G PCM 4 measurement device)
