and RING to
, respectively, while the outputs of the buffers show high impedance.
BATR
The current through these resistors is sensed and transferred to the IT pin to allow off-
hook supervision.
PDRRL is used as a transition mode at a mode change from PDRR mode to ACTR mode
(automatically initiated by SLICOFI-2 at a mode change from PDRR to ACTR).
High Impedance (HIR/HIT): In this mode each of the line outputs can be programmed
to show high impedance. HIT switches off the TIP buffer, while the current through the
RING output still can be measured by IT or IL. Programming HIR switches off the RING
buffer.
For Both Operating Modes of SLIC-P (Ringing and Non Ringing):
The Power Down modes are intended to reduce the power consumption of the linecard
to a minimum: the PEB 4266 is switched off completely, no operation is available.
With respect to the output impedance of TIP and RING, the following Power Down
modes have to be distinguished:
The PDH mode offers high impedance at TIP and RING.
High Impedance (HIRT): The output buffers of the Tip and Ring line show high
impedance.
