1.6 Specifications
HLC Card (Hybrid Line Circuit card ) (KX-T96170) Functions
1.
Standard SLT interface. SLT interface is quite the same as that of SLC card.
2.
PT and DSS console interface. PT and DSS console interface is quite the same as that of
PLC card.
Note
Digital DSS Consoles KX-T7440 and KX-T7441 can be connected to this card.
In this case, however, ANSWER and RELEASE buttons on the KX-T7441 do not function.
3.
Interface for PT (KX-T123230D, KX-T123235, KX-T7130) with OHCA feature.
This is quite the same as that of PLC.
4.
Power failure transfer by each port. (when using SLT)
Power failure transfer is quite the same as that of SLC card.
5.
Diagnostic transfer by each port. Diagnostic transfer is quite same as that of SLC card.
HLC Card (Hybrid Line Circuit card ) (KX-T96170) Operation
1.
LED indicator on the HLC card lights when the system reset or HLC local reset occurs.
PLC Card (KX-T96172) (Proprietary Line Circuit card (8 PT entensions/card))
Functions
1.
PT and DSS console interface. (8 circuits/ card)
Maximum loop resistance : 40 ohms
Power supply 1 : +30V (supplied through speech path, and with current limitation circuit).
Power supply 2 : +15V (supplied through data line).
Note
