2.1 iPECS
Modules
2.1.1 MFIMs
(Multi-Function
Interface gateway Module)
The Multi-Function Interface gateway Modules (MFIM100, MFIM300 and MFIM600), which are the
main controller for iPECS and employ the iPECS protocol, extend telephony resources and call
processing to the iPECS modules and terminals. Multi-Function Interface gateway Modules
incorporate miscellaneous interfaces for Music-On-Hold (MOH), Background Music (BGM), contact
monitors for Alarm and Doorbell inputs, Loud Bell Contacts, and Power Fail Transfer (PFT) relays.
Also, Multi-Function Interface gateway Modules 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 4.5.2.
There are several types of MFIMs as shown in Table 2.1.1-1.

Not all capacities can be simultaneously achieved, for detailed capacity specifications refer to
section 3.1.
With the exception of the MFIM600, MFIMs incorporate 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 6 simultaneous full duplex
packet voice channels. Transcoding for major codecs (g.711, g.729a, g.723.1) is provided by on-
board DSP circuitry. The VSF is used for the integrated Automated Attendant and Voice Mail
services available in the iPECS software. The MFIM100 and MFIM300 have a voice storage
capacity of approximately 210 minutes.
MFIMs have a 10/100 Base-T Ethernet interface, the “LAN1” RJ-45 type connector, which is the
interface to the iPECS call server features and functions. Each MFIM has a second 10/100 Base-T
Ethernet interface “LAN2” RJ-45 type connector. The “LAN2” port is employed for redundant
processor operation. For redundant processor operation, the LAN2 ports of the main and back-up
MFIM are interconnected using a standard RJ-45 cable. The Ethernet ports incorporate auto MDI,
MDIX switching, therefore, both straight and cross cables can be used.
MFIMs have front panels as shown in Figure 2.1.1-1, which include:

Power jack for the AC/DC adapter; see section 2.1.15 AD/DC adapter –G-.
