Introduction
The 2-port analog subscriber circuit interface module and 1-port voice AT0 loop trunk interface
module (SIC-2FXS1FXO) serve to access and handle three channels of analog voice signals over
data communication networks. Two FXS interfaces and one FXO interface are available on a
SIC-2FXS1FXO module:
•
FXS interfaces are analog subscriber line interfaces that provide ordinary analog telephone and
fax access and also can connect AT0 loop trunks of exchanges.
•
FXO interfaces are loop trunk interfaces that provide access of common subscriber lines of
exchanges.
