Description
7
LAC
This bit selects the LLOS, SLOS and AIS criteria.
0: T1.231 (in T1/J1 mode) / G.775 (in E1 mode). (default)
1: I.431 (in T1/J1 mode) / ETSI 300233 & I.431 (in E1 mode).
6 - 4
ALOS[2:0]
These bits select the amplitude threshold (Q). When the amplitude of the data is less than Q Vpp for N consecutive pulse inter-
vals, LLOS is declared. The consecutive pulse intervals (N) are determined by the LAC bit (b7, LOS,...).
The ALOS[2:0] settings for Normal Receive mode and Line Monitor mode are different. Refer to below tables.
3 - 2
TALOS[1:0]
These bits select the amplitude threshold. When the amplitude of the data is less than the threshold for a certain period, TLOS is
declared. The period is determined by the TDLOS bits (b1~0, LOS,...). When the amplitude of a pulse is above the threshold,
TLOS is cleared.
For Differential line interface:
00: 1.2 Vp.
01: 0.9 Vp. (default)
10: 0.6 Vp.
11: 0.4 Vp.
For Single Ended line interface:
00: 0.61 Vp.
01: 0.48 Vp. (default)
10: 0.32 Vp.
11: 0.24 Vp.
