Before the block diagrams are shown, the downlink and uplink signal
paths are described below.
Alarm is described on page 5-16.
Repeater setup is described on page 5-16.
Downlink Signal Path
The downlink signal path, i.e. from the base station through the repeater
to the mobile station, is described for channel selective GSM operation,
channel selective CDMA operation, and band selective operation under the
block diagrams on the following pages.
Uplink Signal Path
The uplink signal path, i.e. from the mobile station through the repeater
to the base station, is identical to the downlink path the other way round.
Only some levels and component values differ.
The high power CDMA repeater has, however, a booster amplifier in the
downlink path only.
