Power Down Resistive (PDRH for SLIC-E/-E2/-S/-S2 and PDRH, PDRR for SLIC-P)
The Power Down Resistive mode is the standard mode for none-active lines. Off-hook
is detected by a current value fed to the DSP, is compared with a programmable
threshold, and is filtered by a data upstream persistence checker. The power
management SLIC-P can be switched to a Power Down Resistive High (PDRH) mode
or to a Power Down Resistive Ring (PDRR) mode.
High Impedance on Ring and Tip (HIRT)
The line drivers in the SLIC-E/-E2/-P are shut down and no resistors are switched to the
line. Off-hook detection is not possible. In HIRT mode, the SLICOFI-2 is able to measure
the input offset of the current sensors.
Power Down High Impedance (PDH)
In Power Down High Impedance mode, the SLIC is totally powered down. No off-hook
sensing can be performed. This mode can be used for emergency shutdown of a line.
Active High (ACTH)
A regular call can be performed, voice and metering pulses can be transferred via the
telephone line, and the DC loop is operational in the Active High mode using
Active Low (ACTL)
The Active Low mode is similar to the Active High mode. The only difference is that the
SLIC uses a lower battery voltage,
Active Ring (ACTR)
The Active Ring mode for the SLIC-E/-E2 is different from the Active Ring mode for the
SLIC-P. The SLIC-E/-E2 uses the additional positive voltage
whereas the SLIC-P switches to the negative battery voltage
Preliminary Data Sheet
that no programming is possible until the SLICOFI-2 wakes up. In IOM-2 mode, the
identification request can be used as a wake up signal as this command is
independent of the internal clock. In the PCM/ C mode, it is recommended that CS
be set to 0 for only one clock cycle.
After a wake up from Sleep mode, the SLICOFI-2 enters the PDRH or PDRR mode.
To re-enter Sleep mode, it is necessary to first perform a mode change to any Active
mode on at least one channel.
