The PPR (Periodical Performance Report, see ANSI T1.403) status which is sent out in
the data link channel of the extended superframe format (ESF/F24 only) automatically
(dependent on the bit CCR5.EPR) or manually (if setting CMDR2.XPPR to ´1´; then last
PPR is sent once; CMDR2.XPPR bit is cleared automatically after sending was finished)
can additionally be read from registers PPR0 and PPR1, too. Performance data is
updated once every second. Only the actual performance parameters (for t
accessible via registers. New data is available immediately after the one second interrupt
is triggered and must be read before the next one-second interrupt occurs.
12.3
Automatic loop switching (activation and deactivation) based on detected In-Band Loop
codes can be done.
Detection and generation of In-Band Loop code is supported on line and system side
independent from another.
Detection, generation and loop switching is possible on all eight channels, independent
from another.
Framed and unframed In-Band loop code can be generated and detected.

PRBSTS settings are not
valid; SW compatibel to
QuadFALC
“Framed” mode if TS0 is
deselected;
CAS in E1 not disturbed if
TS 16 is deselected
Implies a “framed” mode
