Interface Circuit  
Key Features  
Description  
• Selectable overhead voltage principle  
– All adaptive: The overhead voltage  
The PBL 386 65/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated  
circuit for use in DLC, Central Office and other telecommunications equipment. The  
PBL 386 65/2 has been optimized for low total line interface cost and a high degree  
of flexibility in different applications.  
The PBL 386 65/2 emulates a transformer equivalent dc-feed, programmable  
between 2x25 Ω and 2x900 Ω, with short loop current limiting adjustable to max  
65 mA.  
A second lower battery voltage may be connected to the device to reduce short  
loop power dissipation. The SLIC automatically switches between the two battery  
supply voltages without need for external components or external control.  
The SLIC incorporates loop current, ground key and ring trip detection functions. The  
PBL 386 65/2 is compatible with loop start and ground start signalling.  
Two- to four-wire and four- to two-wire voice frequency (vf) signal conversion is  
accomplished by the SLIC in conjunction with either a conventional CODEC/filter or  
with a programmable CODEC/filter, e.g. SLAC, SiCoFi, Combo II. The programmable  
line terminating impedance could be complex or real to fit every market.  
Longitudinal line voltages are suppressed by a feedback loop in the SLIC and the  
longitudinal balance specifications meet the DLC requirements.
