Figure 5. FCC Mode I/V Characteristics,
DCV[1:0] = 00, MINI[1:0] = 00, ILIM = 0
For applications that require current limiting per the
TBR21 standard, the ILIM bit can be set to select this
mode. In the current limiting mode, the dc I/V curve is
changed to a 2000
slope above 40 mA, as shown in
Figure 6. The DAA operates with a 50 V, 230
feed,
which is the maximum line feed specified in the TBR21
standard.
Figure 6. TBR21 Mode I/V Characteristics,
DCV[1:0] = 11, MINI[1:0] = 00, ILIM = 1
The MINI[1:0] bits select the minimum operational loop
current for the DAA, and the DCV[1:0] bits adjust the
DCT pin voltage, which affects the TIP/RING voltage of
the DAA. These bits permit important trade-offs to be
made between signal headroom
and minimum
operational loop current. Increasing the TIP/RING
voltage
provides
more
signal
headroom,
while
decreasing the TIP/RING voltage allows compliance to
PTT standards in low-voltage countries such as Japan.
Increasing the minimum operational loop current above
10 mA also increases signal headroom and prevents
degradation of the signal level in low-voltage countries.
Finally,
Australia
has
separate
dc
termination
requirements for line seizure versus line hold. Japan
mode may be used to satisfy both requirements.
However, if a higher transmit level for modem operation
is desired, switch to FCC mode 500 ms after the initial
off-hook. This satisfies the Australian dc termination
requirements.
6.15. AC Termination
The DAA provides one ac termination impedance with
the Si3060 and Si3062 line-side devices, two ac
terminations with the Si3065, and four ac termination
impedances with the Si3061 and Si3063 line-side
devices. With the Si3060 and Si3062 line-side devices,
the ACT bits (Register 16) are forced to zero to provide
the necessary 600
termination to satisfy FCC Part 68.
With the Si3061 and Si3063, The ACT and ACT2 bits
can be programmed to provide three ac impedance
selections in addition to the real, nominal 600
termination. The available ac termination settings are
With the Si3065 line side device, only the ACT2 bit is
available to enable either the 600
ac termination to
meet FCC Part 68 (ACT2 = 0) or a complex impedance
to meet TBR21 (ACT2 = 1).
There are two selections that are useful for satisfying
non-standard ac termination requirements. The 350
+
(1000
|| 210 nF) impedance selection is the ANSI/
EIA/TIA 464 compromise impedance network for trunks.
The last ac termination selection, ACIM[3:0] = 1111, is
