Subscriber line interface circuits from Silver Telecom are ideal for all applications from network access and low-cost business telephone systems through to the latest CTI and VoIP products.
These SLICs have high density packaging formats (72 pin SIMM and SIL) and a minimum of external components are required; intelligent power-down reduces idle power consumption to <50 mW and they can drive long loops (over 10 km).
Other features are: battery reversal and on-hook transmission for CLI; programmable impedance; programmable loop current and switch hook detection threshold; meter pulse injection; soft shutdown under fault conditions.
* Quad SLICs: Ag1400 Quad SLIC - four-channel SLIC for high functionality and high density line card applications; Ag1405 Quad SLIC includes MP injection and programmable impedance; Ag1450 Quad ringing SLIC - four-channel short loop SLIC with onboard ringing generation; Ag1455 Quad ringing SLIC - four-channel short loop SLIC with onboard ringing generation and programmable impedance; Ag1415 low cost Quad SLIC - basic functionality for PABX and CTI applications.
* Dual SLICs: Ag1250 dual ringing SLIC - two-channel short loop SLIC with onboard ringing generation; Ag1255 dual ringing SLIC - two-channel short loop SLIC with onboard ringing generation and programmable impedance.
* Single SLICs: Ag1110 SLIC - single channel SLIC for low-cost applications, needing low power and long line length.
