This is valid for all backup equipment or corrections. Using the network sensing devices as return path generators and analyzing the signal back in the headend will help in the commissioning and ongoing maintenance of the return path, just as well as the forward path. Network management may well make the difference. We have long been dependent on services such as water, gas and electricity, but only recently have we come to expect the same level of reliability in our access to information and the telecommunications network. This public awareness of quality, combined with the ever-growing number of new services on the network, makes network management systems indespensible.
Network monitoring has four imperative levels.
The headend is the first layer, the vital source of all signals. No matter how good your network is, outages of channels in the headend will result in an outage for the whole network. The fourth layer should monitor the health of the return path and provide information about ingress, impulse noise and other monsters lurking in the upstream. All rights reserved.
