Monitoring Alarms for Broken Optical Links
There are several types of broken optical link alarms for both host units and remotes.
In the following table,
upstream
refers to units or optical links closest to the base station
or off-air signal source, and
downstream
refers to units or optical links farthest away.
For example, in Figure 18-2 Host A is the upstream unit, and Host B is the downstream
unit. Remote A is the upstream unit relative to Remote B, but also the downstream
remote relative to Host A.
