4.7. Off-Hook
The communication system generates an off-hook
command by setting the OH bit. With the OH bit set, the
system is in an off-hook state.
The off-hook state is used to seize the line for incoming/
outgoing calls and can also be used for pulse dialing.
When the DAA is on-hook, negligible dc current flows
through the hookswitch. When the DAA is placed in the
off-hook state, the hookswitch transistor pair, Q1 and
Q2, turn on. This applies a termination impedance
across TIP and RING and causes dc loop current to
flow. The termination impedance has both an ac and dc
component.
When executing an off-hook sequence, the Si3016
requires 1548/Fs seconds to complete the off-hook and
provide phone-line data on the serial link. This includes
the 12/Fs filter group delay. If necessary, for the shortest
delay, a higher Fs may be established prior to executing
the off-hook, such as an Fs of 10.286 kHz. The delay
allows for line transients to settle prior to normal use.
4.8. DC Termination
The Si3016 has four programmable dc termination
modes that are selected with the DCT[1:0] bits in
Register 16.
FCC mode (DCT[1:0] = 10 b), shown in Figure 10, is the
default dc termination mode and supports a transmit full
scale level of –1 dBm at TIP and RING. This mode
meets FCC requirements in addition to the requirements
of many other countries.
