LOW COST PBX SLIC
1
RING Ring. Connects to the subscriber line Ring through the n/c pole of the ringing relay.
2
TIP
Tip. Connects to the subscriber Tip.
3
TC
Tip Clamp. A diode must be connected externally between TC and Tip to conduct
ringing current.
4
RT
Ring Trip. A capacitor is connected externally between RT and GND to filter out the AC
component of the ringing signal. Must be switched out during LD dialling.
5
GND Analog Ground. Normally connected to system ground.
6
VIN
Audio In. This is the analog input signal from the codec (which is output on Tip and
Ring).
7
VCC
+5V Positive Supply. This pin must be connected to +5V.
8
VOUT
Audio Out. This is the analog output signal (from Tip and Ring) to the codec.
9
VBAT
Battery Voltage. The negative supply rail. Typically -48V.
10
SHK
Switch Hook Current. Indicates loop current is flowing (such as when off hook) when at
logic 1.
11
LO
Loop Off. A logic 1 removes loop current, used during fault conditions.
12
RDI
Relay Driver Input. A logic 1 activates RDO.
13
RDO
