Introduction to the EDA 1200 System

2.2.2 Network Devices

EDA 1200 is a device based system. That is, all the devices are mechanically

and electrically independent. Any connections between nodes are done with

cables. All the nodes use -48 V DC power.

The node environment ratings are:

• Central Office Equipment, -5ºC to +45ºC or +55ºC. This equipment can be

placed outside the central office if the environment is controlled.

• Outside Equipment, -20ºC to +70ºC.

• Hardened Outside Equipment, -40ºC to +75ºC.

The node mounting methods are shown in Table 3 on page 13.

Table 3 Node Mounting Methods

Nodes mounted in 19” or ETSI racks

Nodes mounted on the rods of

rod-based subracks

The EDA 1200 rod mounted devices are mounted in subracks. EDA 1200 has

a variety of dedicated subracks, as well as a general purpose subrack.
