Figure 36 shows the relationship between FSC, DCL, DD# and DU#:
FC Mode 1
FC mode 1 is similar to FC mode 0. The FSC pulse is shifted by half a RCL period to the
right compared to FC mode 0. It can be used for general purposes.
FC Mode 2
FC mode 2 is similar to FC mode 3. The FSC pulse is shifted by half a RCL period to the
left compared to FC mode 3. It can be used for general purposes.
Application Examples of the Different FC Modes
FC Mode 0
FC mode 0 applies for IOM-1 multiplexed mode applications, i.e. for IOM-1 interfaces
with 2.048 Mbit/s data rate. Accommodated layer-1 devices: SBC (PEB 2080),
IBC (PEB 2095), IEC-T (PEB 20901/20902), …
In IOM-1 mux. mode, the frame is synchronized with a negative pulse with a duration of
one DCL period which marks bit number 251. The bits are transmitted with the falling
clock edge and received with the rising clock edge.
