32.4Tap-offs

The network splitter makes it possible to create tap-offs (see figure 32.3). Please that tap-offs are never redundant, because it is not possible to create a tap-off ring. If the cable between the network splitter and the call station B breaks, call station B is not functioning anymore, hence the tap-off is not redundant.

32.5Spare amplifiers

Besides using redundant cabling it is also possible to add spare amplifiers to the system (see chapter 8).

Spare amplifiers give back-up capacity if an amplifier has a defect.

Refer to 8.3.5.5 for information about power amplifiers. Refer to 10.3.5.3 for information about basic amplifiers.

Caution

Do not mix spare power amplifiers with spare basic amplifiers. The amplifiers are not compatible and the configuration software does not support the assignment of a basic spare amplifier channel to a main power amplifier or a spare power amplifier to a main basic channel.
