Specific T1/J1 Initialization
The following is a suggestion for a basic initialization to meet most of the T1/J1
requirements. Depending on different applications and requirements any other
initialization can be used.

Data Sheet
Write access to unused register addresses: should be avoided, or set to ‘00’hex.
All control registers (except XFIFO, XS1-12, CMDR, DEC) are of type: Read/Write
Line Interface Initialization (T1/J1)
Framer Initialization (T1/J1)
Function
The FALC
as well as the digital line interface. For the analog line interface the
codes AMI (with bit 7stuffing) and B8ZS are supported. For the
digital line interface modes (dual or single rail) the FALC
supports AMI (with bit 7 stuffing) and B8ZS.
LOS detection after 176 consecutive “zeros” (fulfills G.775 spec,
Bellcore/AT&T)
LOS recovery after 22 “ones” in the PCD interval. (fulfills G.775,
Bellcore/AT&T)
LOS threshold (fulfills G.775, see DC characteristics).
Additional Recovery Interrupts. Help to meet alarm activation and
deactivation conditions in time.
Automatic pulse density check on 15 consecutive zeros for LOS
recovery condition (Bellcore requirement)
Selection of framing sync conditions
Select framing format
The transmission of RAI via the line interface is done automatically
by the FALC
(FRS0.LFA = 1). If framing has been reinstalled RAI is
automatically reset
