AISG cable requirements
Standard AISG cable
The standard AISG cable consists of an 8-pin circular DIN connector (AISG v2.0) that
connects directly to the Alcatel-Lucent B25 RRH4x30. The AISG cables can be obtained
from Alcatel-Lucent in lengths of 1 m to 80 m.

AISG daisy chain configuration
The Alcatel-Lucent B25 RRH4x30 has one AISG output port. An AISG daisy chain
configuration can be created by connecting the Alcatel-Lucent B25 RRH4x30 AISG
output port to another external AISG device.

AISG configurations
The figures in the following paragraphs show typical examples of AISG configurations.
Actual customer deployment may vary depending on requirements.
Actual customer deployment may vary depending on requirements.
The components of the AISG solution offered by Alcatel-Lucent include some or all of
the following:
• Smart Bias Tee (top and bottom)
• Smart Bias Tee ground kit
• AISG surge protector
• AISG cables
• AISG cable ground kit
• RF surge protection (for indoor applications)
For outdoor AISG cable home run solutions, the AISG cable must be grounded every
60 m (200 ft). For indoor AISG cable home run solutions, the AISG cable must be
grounded at the hatchplate and every 60 m (for the outdoor portion of the run). All Smart
Bias Tees must be grounded. All RF cable grounding and surge suppression rules must be
followed as previously specified in this document.

Important! The Alcatel-Lucent B25 RRH4x30 has an integrated Bias Tee on each
duplexed RF port (TxRx1 and TxRx2) used in 2 Tx mode. Thus in the following
example AISG configurations, an external Smart Bias Tee is not required for the
TxRx1 and TxRx2 ports on the Alcatel-Lucent B25 RRH4x30.
