Overview
HUAWEI BBU3910 is a baseband processing unit. It processes the baseband signals of the BTS.
The BBU3910 is a baseband control unit of DBS3900. Compared with the BBU3900, its backplane has agreater switching capability and the baseband boards installed in slots 0 to 5 all can process baseband signals.
A base station can be configured with a maximum of two BBU3910s or one BBU3900 and one BBU3910 to provide higher processing capabilities.
The BBU3910, which has a case structure, is 19 inches wide and 2 U high. It can be installedin an indoor or outdoor protective cabinet.
BBU3910 subrack dimensions (H x W x D): 86 mm x 442 mm x 310 mm. The four-layered subrack can house 8 service boards, 2 power modules, and 1 fan module.
The BBU3910 has the following functions:
-
Manages the entire base station system in terms of operation, maintenance, and systemclock.
-
Processes signaling messages.
-
Provides physical ports for information exchange between the base station and thetransport network.
-
Provides an OM channel between the base station and the LMT, SMT, or U2000.
-
Processes uplink and downlink baseband signals.
-
Provides CPRI ports for communication with RF modules.
-
Provides ports for communication with environment monitoring devices.
