DET: On/OffHook Signalling; togetherwith GDK/AL it is setLow also in case of Thermal Alarm or Ground-Key.
GDK/AL : Thermal Alarm or Ground-Key Signalling
(1) : DET and GDK/AL signallingfunction is related to D0,D1,D2 and itdoesn’t depend on R0 and R1 setting.
As in Slave mode the control is performed
through a parallel bus, with independent chip se-
lects, CSIN and CSOUT, for inputs and outputs.
In Automatic Activation, once Active mode is se-
lected the device automatically selects the proper
operating mode (Active, Stand By or H.I. feeding)
depending on the loop status in order to optimise
the power consumption.
In order to guarantee the proper behaviour of the
internal state machine the ”CKRING” signal must
be always applied,this signal in fact is usedto gen-
eratethe ”WTIME” delay(see Appendix)necessary
to properlyperformautomaticstatechange.
Power-Down
It’s an idle state characterised by a very low
power consumption; any functionalityis disabled;
only
relays Rel0 and Rel1 can be
proper settingof bitsR0 and R1.
It can be set during out of service periods just to
reducethe power consumption.
It is worth noticing that two other conditions can
set the Slic in idle state but with some differences
as reportedin the table:

Ringing
When Ringing mode is selected the STLC3080
activatesthe ringing relay injecting the ringing sig-
nal on the line.
As a Ring-Trip is detected the logic indicator DET
is set Low and the ringing relay is automatically
switched-off without waiting for the card control-
ler command(auto ring-trip).
DET remains latched Low
mode is modified.
Ringing relay drive signal RELR must be synchro-
nised to a clock applied to CKRING input. This
clock is derived from the ringing signal with
proper time delay, according to the activation /
deactivationtime of the relay.
RELR is activated on the low level of CKRING
clock. The duty cycle of CKRING can be modified
in order to activate the RELR when required:
CKRING low must last 1
μ
s minimum.
All the relay drivers are open-drain with the
sourceconnectedto RGNDpin.
Each relay driver integratesa protectionstructure
to avoid external kick-back diodes using both 5V
or 12V relays.
The ring trip circuit and its behaviour is described
in AppendixD.

The relevant feature of this setting is that when
Active Mode (D0D1D2=1XX) is set by the exter-
nal control , internally, the device is able to select
between three operative states according to the
