Figure 2 Point-to-point Link as Sub-multiplexer

1.2 Planning

The network administrator must determine how the Nx8-DualMUX units will work in the

network and understand the applications that will utilize each of the available channels. Some

of this work is made easier by the fact that link bandwidth requirements are easily determined

by summing the bandwidth needs of each channel port that is planned to be used, and

adding the fixed overhead. Inband control signal transport should also be considered when

needed, as some bandwidth is required to support this function.

Additionally, the network administrator should have in mind other considerations that are

factors in planning for the installation. Some of these are:

1) Power requirements, including redundancy

2) Ventilation and cooling

3) Rack space requirements

4) Cabling & distances between equipment

5) Ease of access for maintenance
