MFIM50B provides four (4) ISDN Basic Rate Interface ports (2B+D) which support the ‘T’ interface
as described by ETSI 300.012 based on the ITU-T Recommendations I.430, and two (2) FXS
interfaces which allow standard analog Single Line Telephone (SLT) devices access to BRI Lines,
other stations, and most features of the system through the use of “dial codes”.
ISDN-BRI interfaces can be installed in the TE (Terminal Equipment) mode
FXS interfaces provide 48 volt DC feed circuit, pulse, DTMF dial signal detection, and T.38
protocol for Fax over IP... A ring generator and message wait source are integrated. FXS allows
Single Line Telephones to be connected up to 4 Kilometers (13,000 feet) from the gateway using
24 AWG wire.
