pti! "T# 600 is a %'H()'H integrated short*haul

digital microwave transmission system developed +y

Huawei.

The maimum microwave transmission capacity is)T-*.

The system provides the +ac/haul transmission lin/ in

the mo+ile communication system or private networ/,

and also networ/s with optical transmission

euipments.
