2.1.1 LIK-MFIM50 (Multi-Function Interface gateway Module 50)
Multi-Function Interface gateway Modules (LIK-MFIM50A, LIK-MFIM50B), which are the main
controller for iPECS-LIK50 and employ the iPECS protocol, extend telephony resources and call
processing to the iPECS modules and terminals. LIK-MFIM50A incorporates CO line interfaces for
CO/PBX Loop Start Line MFIM50B incorporates ISDN Basic Rate Interface (2B+D). Both models
support FXS interfaces for standard analog Single Line Telephone (SLT) devices, miscellaneous
interfaces for Music-On-Hold (MOH), Background Music (BGM), contact monitors for Alarm and
Doorbell inputs, and Loud Bell Contacts. Power Fail Transfer(PFT) relays is only MFIM50A. In
addition, LIK-MFIM50A MFIM50B include battery back-up circuitry using a long-life Lithium battery
to maintain the real-time clock and prevent loss of system database during power fail, refer to
section 4.4.1 & 4.4.2.
There are two types of MFIMs as shown in Table 2.1.1-1.

Each MFIM50 incorporates an IP Gateway for access to standards based (SIP and H.323 v3) and
iPECS protocol Voice over IP (VoIP) communications networks and a voice storage medium, the
VSF. The IP gateway supports up to 8 simultaneous full duplex packet voice channels with
transcoding for major codecs (G.711, G.729a, G.723.1) provided by on-board DSP circuitry. The
VSF is used for the integrated Automated Attendant and Voice Mail services available in the
