Low Voltage and High Density Compact Gateway
maximum capacity in the bridge table, increasing the ageing time is recommended.
Bandwidth Limitation
The real bandwidth differs slightly from the specified limit and depends on a number of factors, like traffic
type, number of users, channel conditions, line conditions, etc.
Reconfiguration Time in MV MAC
The protocols and algorithms that allow the reconfiguration of ring topologies in a short time (a few seconds)
when a problem in the network appears are not included.
Regulation Power Mask
The regulation calculated power mask is slightly displaced to low frequencies. A correction to high
frequencies of around 20 kHz must be introduced in each notch definition to compensate this effect. The
notches of the IARU power mask are also calculated and they are also displaced. As a result of this
displacement, two of the notches included in IARU regulation are a few dB less attenuated than required.
Number of hops in Time Division Domains
The number of hops supported in a Time Division Domain is ten. In networks were more hops are needed, it
is recommended to use several Frequency Division Domains.
