Preliminary
Active (ACTL, ACTH): These are the regular transmit and receive modes for voice
band. The line driving section is operated between
Ringing:
Active Ring (ACTR): In order to provide a balanced ring signal of up to 85 Vrms or to
drive longer telephone lines, an additional negative battery voltage
making possible a higher voltage across the line. Transmission performance remains
unchanged compared with ACT mode.
Ring on Tip (ROT): An unbalanced ring signal up to 50 Vrms can be fed to the Tip line.
The Ring line is fixed to a potential near
Ring on Ring (ROR): An unbalanced ring signal up to 50 Vrms can be fed to the Ring
line. The Tip line is fixed to a potential near
PDRH is a power down mode providing a connection of 5 k
and RING to
The current through these resistors is sensed and transferred to the IT pin to allow off-
hook supervision.
PDRHL is used as a transition mode at a mode change from PDRH mode to ACTH mode
(automatically initiated by SLICOFI-2 at a mode change from PDRH to ACTH).
