... Si2456/Si2433/Si2414 DC Termination The Si2456/33/14 has four termination modes that are selected with DCT (U67, bits 3:2). FCC mode (DCT = 10), shown in Figure 9, 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 ...

... The traditional way of dealing with this problem is to put a parallel RC shunt across the hookswitch relay. The capacitor is large Si2456/Si2433/Si2414 (~1 µ F, 250 V) and expensive. In the Si2456/33/14, the OHS bit (U67, bit 6) can be used to slowly ramp down the loop current to pass these tests without requiring additional components ...

It takes approximately one second to return to normal dc operating conditions. The BTD and ROV bits are sticky, and they must be written reset. After the BTE, ROV, and BTD bits are all cleared, the BTE bit can be set to re-enable billing tone detection ...
