The CMC1 Media Gateway - Overview

The CMC1 Media Gateway supports the DEFINITY® Server CSI and the Avaya S8100 Media Servers. It can be mounted on a wall or on the floor, and uses an AC-only power supply. The control carrier contains two control slots, one for the processor and the other for the tone clock. Slot 3 to slot 10 can contain optional port circuit packs and service circuit packs.
 

The CMC1 Media Gateway has the following characteristics:

· The size is 25.5 inches wide, 24.5 inches high, and 11.3 inches
  deep. It is designed for wall mounting. Mounted on the floor or
  on a table where required.

· Ten universal port slots plus one power supply slot per CMC1.

· Standard reliability option only.

· Is limited to one PN that is made up of a maximum of three
  CMC1 Media Gateways. A PN consists of a control CMC1 that is
  designated "A". The second and third CMC1s are optional and
  are designated cabinets "B" and "C" respectively. Cabinet
  address ID within the PN is set using the DIP switch on the
  backplane.

· Circuit packs are inserted and removed from the left side.
  Cabinet I/O is from the right side.

· The CMC1s in a port network are interconnected via shielded
  TDM/LAN bus cables.

· The CMC1 is AC powered only. There are no internal batteries,
  and no DC power option.

· Two 12-volt DC variable-speed fans integrated into the bottom
  of the cabinet provide CMC1 cooling. The fans force air through
  a filter and up through the cabinet. Air exits from the back of
  the cabinet. Speed control is provided by the 650A Global
  Power supply. The 650A varies the fan input voltage between
  8VDC and 14VDC depending on a temperature sensor that is
  mounted in the power supply. The fan assembly includes the
  two fans, a frame to which the fans are attached, wiring, and a
  connector that plugs into the backplane. The assembly is easily
  installed and removed. The entire assembly must be replaced as
  a unit if a fan fails.
