Silvertel has developed analog telecom interface modules that are easy to use, small in size and yet require very few extra components. Available in single in line (SIL) or dual in line (DIL) packages.

SLIC module
Silvertel’s Subscriber Line Interface Circuit (SLIC) modules can be used for analog telephone line interface applications, enabling signals to be transmitted and received from a telephone line, feed power to the line and to monitor the line condition. The modules are ideal for use in ISDN Terminal Adaptors, Internet Telephony (VoIP), Computer Telephony Integration (CTI), Wireless Local Loop (WLL), Fixed Cellular Terminals (FCT), Fixed Wireless Terminals (FWT) and Small Office Home Office (SOHO) applications.

PSTN module
Silvertels’ PSTN interfaces are also known as Trunk Interfaces, Foreign exchange Office (FXO) circuits, Data Access Arrangements (DAA) and Central Office Interface Circuits (COIC). Silver Telecom PSTN modules are suitable for a wide range of applications, meeting the requirements of CTR21, FCC Pt.68, UL60950, AS NZ3260 and AS ACIF S043. The ability to provide a programmable d.c. mask, line and network impedances gives our PSTN modules the flexibility to be used in any market. On-Hook reception allows support for Caller Line ID and by using transformer isolation this provides high common-mode rejection for use in ungrounded systems as well.
