Function
Receive Signaling Marker
E1/T1/J1 mode: Marks the time-slots which are
defined by register RTR1-4 of every received
frame on port RDO.
T1/J1 CAS-BR mode: When using the CAS-BR
signaling scheme, the robbed bit of each
channel every six frames is marked, if it is
enabled via register XC0.BRM = 1.
General: In 4096 kbit/s mode RSIGM is active
only during the channel phase selected by
RCO.SICS.
Receive Multiframe Begin
RMFB marks the beginning of every received
multiframe (RDO, first bit of the FAS word in
frame 1 of a multiframe). Active high for one
2048 kbit/s period. In 4096 kbit/s mode RMFB is
active during the first two bits of channel phase
one of a multiframe.
In T1/J1 mode the function depends on
programming bit XC0.MFBS:
MFBS = 1: RMFB marks the beginning of every
received multiframe (RDO).
MFBS = 0: Marks the beginning of every
received superframe. Additional pulses every 12
frames are provided when using ESF/F24 or
F72 format.
