An Explanation of MDFs, IDFs, RIDFs and
EDPs Intercom systems or public address systems
may be deployed by using analog, digital (VoIP)
technologies or a combination of both (hybrid).
When designing intercom systems or public address
systems, there are certain common considerations
involved regardless of the technology
deployed.   One of those considerations is
simply, where to locate the common equipment.
Common equipment may include amplifiers, power
supplies, system intercom cards or anything else
that will be shared amongst multiple speakers. In
wired systems, or subsystems, it is always
advantageous to locate common equipment as close
as practical to the speakers that it serves. This
is why we use MDFs, IDFs, RIDFs and EDPs.   MDFs
are Main Distribution Frames. In an analog
based Valcom system, the MDF is defined as the
physical location where the CPU card will be
installed. The MDF may also house other system
circuit cards, power supplies for common
equipment, clock correction equipment,
etc.   IDFs are Intermediate Distribution
Frames. In an analog based Valcom system, IDFs
are simply intermediate wiring termination points
for classroom and hallway speakers, clocks, etc.
on their copper journey back to the system
circuit cards. IDFs often house power supplies
for common equipment.   RIDFs are Remote
Intermediate Distribution Frames. In an
analog-based hybrid Valcom system, the RIDF is
defined as the physical location where Ethernet
addressed circuit cards will be installed. RIDFs
allow system circuit cards to be installed near
the speakers that they serve. This eliminates
expensive feeder cables. The system circuit cards
installed in RIDFs are connected to the CPU card
via Ethernet. RIDFs may also house power supplies
for common equipment, clock correction equipment,
etc.   Its important to realize that in order
to facilitate close proximity of common equipment
to the speakers that they serve, RIDFs often have
there own satellite IDFs.   EDPs, Ethernet
Distribution Points (a.k.a. Ethernet IDFs), are
simply wiring termination points for analog
speakers, clocks, etc. at IP speaker locations.
EDPs often house power supplies and clock
correction equipment for common equipment.
