Auxiliary Facility Box:

I. Facility type

There are two models for Auxiliary Facility Box, Common Auxiliary Facility Box with 40kA Lightning Protection Box and Heat-Exchanging Auxiliary Facility Box with 40kA Lightning Protection Box.

II. Facility function

Auxiliary Facility Box collects the auxiliary devices of mini BTSs into one box. One Auxiliary Facility Box can provide functions of cable distribution and power distribution to three mini BTSs at most. See  below Table for its function description.

Functions of Auxiliary Facility Box

Function item

Function description

Remarks

Accommodate transmission equipment and provide transmission cable distribution and lightning protection functions

The Auxiliary Facility Box accommodates transmission equipment such as HDSL, microwave IDU, PDH optical transceiver and SDH and also provides lightning protection and cable distribution functions for the signal interfaces of the transmission equipment.

Optional

Provide power supply to the transmission equipment

The Auxiliary Facility Box can provide -48V DC power supply to the transmission equipment.

Provide heating module

When the transmission equipment works in cold area (the temperature is lower than -20?C), configure a heating module to the Auxiliary Facility Box to ensure that the internal temperature in the box meets the working requirements of the transmission equipment.

Provide fan

When the heat consumption of the built-in transmission equipment is no more than 60W (sun radiation not taken into account), the Auxiliary Facility Box can reduce the average temperature inside and outside the box to 10?C below ( in the area whose altitude above sea level is 3000m below) by configuring fans to the box.

Provide fiber splice unit

The fiber splice unit is used to connect pigtail fibers and optical fibers of the transmission equipment in the mini BTS or the Auxiliary Facility Box to meet the requirements of splicing and coiling fibers.

Provide built-in lightning protection box

The Auxiliary Facility Box can provide built-in 40kA lightning protection box to provide safe and reliable electrical surge and sensitive lightning protection to the 220V single-phase low-voltage electrical equipment.

Mandatory

Provide AC power distribution

The Auxiliary Facility Box can provide power distribution simultaneously to three mini BTSs at the maximum and can also provide power distribution for UPS.
