iPECS software with voice storage capacity of approximately 270 minutes. Each MFIM50 has a
10/100 Base-T Ethernet interface, the “LAN” RJ-45 type connector, which is to interface the iPECS
call server features and functions. The Ethernet port incorporate auto MDI, MDIX switching,
therefore, both straight and cross cables can be used.
LIK-MFIM50A
MFIM50A provides four (4) FXO interfaces to support CO/PBX Loop Start Lines, and two (2) FXS
interfaces, which allow standard analog Single Line Telephone (SLT) devices access to CO Lines,
other stations, and most features of the system using “dial codes”.
The FXO interfaces support pulse or DTMF dial signals. Each Interface contains ring and loop
current detection circuits, speech codec and compression functions and loop signaling circuits. The
circuitry and software support tone detection. An optional Call Metering Unit is available to support
call-metering functions. Each LIK-CMU supports four (4) ports and there are two versions, based
on protocol LIK-CMU1216 CMU-50PR. Each version is for different regions as shown below.
1216 – Australia, Denmark, Italy, Spain, Sweden, Belgium, India, Israel, Norway, South Africa
50PR – Australia, India, South Africa, South Korea, United Kingdom
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.
MFIM50A have a front panel as shown in Figure 2.1.1-1, which
include:
Power status LED,
Reset Switch,
Four (4)-position DIP-switch for mode selections,
Ten (10) LEDs,
Four (4) red LEDs display the operating status of the
main processor,
One (1)red LED displays the operating status of VSF,
Four (4) green LEDs, one for status of each CO line,
One (1)red LED displays the operating status of FXS
ports,
One (1) “LAN” RJ-45 Female LAN connector with Speed and
Link/Activity
LEDs,
One (1) DB-9 RS-232 connector and one (1) USB host port,
RCA jack for one music (audio) source -BGM-.
