An example of the use of the Seize state is that of Australia in which requires this stat for the first 300 ms
immediately after going off hook.

To facilitate the quick capture of the loop, the bandwidth of the DC loop is high upon power up. On the
completion of DC loop capture, it should be lowered to avoid the interaction of DC and AC loops. See the
description of the ENNOM bit in Section 11.6.
11.2.1 Current Limit Detection
If the DAA Current Limiting feature is enabled and the device detects a limited condition, then a status bit is
set to give an indication of this event.
11.3 AC Termination
International DAA functionality is supported without any external termination components through the
following functions:
Enable/Disable AC termination ATEN bit at Register 0x16[4].
Select AC termination impedance using the ACZ bits at Register 0x17[4:3]
ACZ Active Termination Loop Setting
00 = 600
(USA, Japan)
01 = 270
+ 750 || 150nF (ETSI ES 203 021-2)
10 = 200
+ 680 || 100nF (China)
11 = 220
+ 820 || 115nF (Australia)
The AC impedance presented to the line can be altered as described in the AC Termination Register
(Register 0x17). This is a part of a feedback loop that monitors the line and feeds an appropriate AC
current back to line, such that the desired impedance looking into the RXP pin (of the 73M1912 LIC) is
realized. Figure 34 shows magnitude response of the impedance matching filter for the case of ETSI ES
203 021-2. It is approximately equal to the inverse of the frequency characteristics of the impedance being
realized.
