Telecom Modules

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

 

SLIC module
Subscriber Line Interface Circuit (SLIC) modules are used for analog telephone line interface applications. They enable signals to be transmitted and received, power to be fed to the line and monitoring of the line condition. The modules are used in applications such as ISDN Terminal Adaptors, Internet Telephony (VoIP), Computer Telephony Integration (CTI), Wireless Local Loop (WLL), Fixed Cellular Terminals (FCT) and Small Office Home Office (SOHO).

 

PSTN module
PSTN or Trunk interfaces are also known as Foreign exchange Office (FXO) circuits, Data Access Arrangements (DAA) or Central Office Interface Circuits (COIC). These modules meet 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.
