Calculation of delay time T (SCLKX cycles) depends on the value X
of the „Transmit Offset“ register XC1/0:
system clocking rate: modulo 2.048 MHz (SIC2.SSC2 = 0)
0
4+ (SC/SD)
with max. delay = (256 * SC/SD) -1
with SC = System clock defined by SIC1.SSC1/0 + SIC2.SSC2
with SD = system data rate
or
system clocking rate: modulo 1.544 MHz (SIC2.SSC2 = 1)
0
4 + (7*SC/BF) + (SC/SD)
with max. delay = (200 * SC/SD) - (7*SC/SD) -1
with SC = System clock defined by SIC1.SSC1/0 + SIC2.SSC2
with SD = system data rate
with BF = Basic Frequency = 1.544 MHz
Delay time T = time between beginning of time-slot 0 ( bit 0 , channel
phase 0) at XDI / XSIG and the initial edge of SCLKX after SYPX /
XMFS goes active.

Receive Remote Alarm Mode
The conditions for remote (yellow) alarm (FRS0.RRA) detection can
be selected via this bit to allow detection even in the presence of
BER 10**-3:
