Detailed description
A CMC1 Media Gateway has the following characteristics:
● A wall-mount design, but also mountable on the floor or on a table where required.
● Ten universal port slots, plus one power supply slot. In the CMC1 Media Gateway that
contains the DEFINITY CSI server (TN2402) and tone clock (TN2182C) circuit packs,
some slots are unavailable for port and service circuit packs. In the remaining CMC1
Media Gateways that are connected to the server, all 10 slots are available for port circuit
packs or service circuit packs.
● Available with the standard reliability option only.
● 25.5 inches (64.8 centimeters) wide, 24.5 inches (62.2 centimeters) high, and 11.3 inches
(28.7 centimeters) deep.
● Weighs from 50 to 60 pounds (22.7 to 27.2 kilograms).
● Limited to one port network (PN) that consists of a maximum of three CMC1 Media
Gateways. A control CMC1 is designated "A". One or two optional CMC1s are designated
"B," and "C," respectively. The DIP switch on the backplane sets the cabinet address ID
within the PN.
● Circuit packs that are inserted and removed from the left side. Cabinet I/O is from the right
side.
● Shielded TDM/LAN bus cables that interconnect the CMC1s in a PN.
● AC-powered only. There are no internal batteries, and external DC power is not an option.
However, an external UPS is supported.
● Two 12-volt DC variable-speed fans in the bottom of the cabinet provide CMC1 cooling.
The 650A Global Power supply provides speed control. The 650A varies the fan input
voltage between 8VDC and 14VDC depending on a temperature sensor that is mounted in
the power supply.
A DEFINITY Server CSI can support up to three CMC1 media gateways.
