3.5.3.2 System LOS (SLOS)
SLOS can only be detected when the transmit system interface is in
Dual Rail NRZ Format mode or in Dual Rail RZ Format mode.
The amplitude and density of the data input from the transmit system
side are monitored. When the input ‘0’s are equal to or more than N
consecutive pulse intervals, SLOS is declared. When the average
density of marks is at least 12.5% for M consecutive pulse intervals
starting with a mark, SLOS is cleared. Here N and M are defined by the
In T1/J1 mode, SLOS detection supports ANSI T1.231 and I.431. In
E1 mode, SLOS detection supports G.775 and ETSI 300233/I.431. The
criteria are selected by the LAC bit (b7, LOS,...).
When SLOS is detected, the SLOS_S bit (b1, STAT0,...) will be set. A
transition from ‘0’ to ‘1’ on the SLOS_S bit (b1, STAT0,...) or any transi-
tion (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the SLOS_S bit (b1, STAT0,...) will
set the SLOS_IS bit (b1, INTS0,...) to ‘1’, as selected by the LOS_IES bit
(b1, INTES,...). When the SLOS_IS bit (b1, INTS0,...) is ‘1’, an interrupt
will be reported by INT if not masked by the SLOS_IM bit (b1, INTM0,...).
SLOS may be counted by an internal Error Counter or may be indi-
cated by the TMFn pin. Refer to Section 3.5.6 Error Counter and
Section 3.5.7.2 TMFn Indication respectively.
