Solution Description:

In SingleSite 1.0, Site9102 provides a standard solution when the Mini-shelter and BTS3900(Ver.D) (referred to as BTS3900) share the site. The -48 V DC BTS3900 is embedded in the Mini-shelter, which supplies power to the BTS3900.

The Mini-shelter shares the site with the BTS3900 in the following two modes:

"1+1 unit Mini-shelters"+BTS3900
"1+1+1 unit Mini-shelters"+BTS3900

Figure 1-1 Mini-shelter sharing site with the BTS3900

NOTE:

If the BTS3900 is installed in the Mini-shelter, the Mini-shelter is used as the equipment cabinet. If only the storage batteries are installed in the Mini-shelter, the Mini-shelter is used as the battery cabinet. If the power supply device, customer equipment, and storage batteries (optional) are installed in the Mini-shelter, the Mini-shelter is used as the power cabinet.
When the Mini-shelter shares the site with the base station, the maximum configuration is 1 BBU+6 RFUs.

1.1 Hardware Model

Mini-shelters

The Mini-shelter is consisting of cabinet, cooling equipment, power system, and rack. The power cabinet, equipment cabinet, and battery cabinet used in this solution are the 2.1 m high cabinets in ITS1000M V100R003C02. ETP48200-A6 (220 V AC single-phase or 380 V AC three-phase input power) is used for the power supply system. The cooling and rack type of the Mini-shelter are shown in Table 1-1.

Table 1-1 Cooling and rack type of the Mini-shelter

Cabinet Type	Cooling Type	Rack Type
Equipment cabinet	AH3000	base transceiver station (BTS) rack
Battery cabinet	PC500D	battery rack
Power cabinet "1+1 unit Mini-shelters"+BTS3900	AH1500D&PC500D or AH1500&PC500D	combined rack: standard 19 inch rack+battery rack
Power cabinet "1+1+1 unit Mini-shelters"+BTS3900	AH1500 or AH1500D	standard 19 inch rack

NOTE:

AH1500 and AH3000 are intelligent AC heat exchangers, AH1500D is intelligent DC heat exchanger, and PC500D is DC air conditioner. For details about the specifications of those cooling equipment, see "Technical Specifications".
In 110 V AC dual-live-wire input scenarios, the cooling type of the power cabinet cannot be AH1500.

Base Station

BTS3900(Ver.D) (-48 V DC) with a 3 U space for customer equipment is used in this solution.

1.2 Equipment Layout

The transmission equipment, digital distribution frame (DDF), GSM antenna and TMA control module (GATM), environment monitoring unit type A (EMUA), environment monitoring unit type B (EMUB), SLPU (monitoring), SLPU (transmission), DCDU-12C and ACDB are installed in the space for customer equipment in the Mini-shelter or BTS3900. Table 1-2 describes the equipment configuration principles.

Table 1-2 Equipment configuration principles

Equipment	Optional/Mandatory	Maximum Quantity	Remarks
Transmission equipment	Optional	-	The power consumption of a single piece of transmission equipment does not exceed 800 W and the power consumption of all pieces of transmission equipment does not exceed 800 W. The heat consumption of a single piece of transmission equipment does not exceed 600 W and the heat consumption of all pieces of transmission equipment does not exceed 600 W. Six or fewer links of power supply are required for the transmission equipment. Maximum 5 U installation space is required for the transmission equipment.
DDF	Optional	1	Configure the DDF when the transmission mode of the base station is E1/T1.
GATM	Optional	2	Configure the GATM when the DRFU is used as the RFU.
EMUA/EMUB	Optional	1	Configure the EMUA or EMUB when the dry contact alarms quantity is 17 to 32.
SLPU (monitoring)	Optional	1	Configure the SLPU (monitoring) when the dry contact alarms quantity is 1 to 16.
SLPU (transmission)	Optional	1	Do not configure the SLPU (transmission) when the transmission equipment is installed in the Mini-shelter. Configure the SLPU (transmission) when the transmission equipment is not installed in the Mini-shelter. NOTE: The space for customer equipment in the BTS3900 is reserved for the GATMs, not for the transmission equipment.
DCDU-12C	Optional	1	Configure the DCDU-12C when the BLVD circuit breakers on the ETP48200 in the Mini-shelter are insufficient.
ACDB	Optional	1	Configure the ACDB according to the customer requirement.

Layout principles

The GATM is installed in the space for customer equipment in the BTS3900.
The SLPU (monitoring), EMUA, or EMUB is installed in the bottom 1 U space for customer equipment in the lower part of the equipment cabinet.
The SLPU (transmission) is installed in the top 1 U space for customer equipment in the lower part of the equipment cabinet.
Equipment in the space for customer equipment in the lower part of ETP48200 in the power cabinet is installed from top down in the following sequence: DDF, DCDU-12C, transmission equipment, and ACDB.
The DDF and transmission equipment are preferentially installed in the space for customer equipment in the lower part of the ETP48200. If the space for customer equipment in the lower part is not enough, install the ACDB and passive equipment in the space for customer equipment in the upper part of the ETP48200.

1.3 Power Distribution

AC Power Distribution

The ETP48200-A6 in the Mini-shelter converts one AC power input into two or three AC power outputs to providing power for the cooling equipment and service outlet unit (SOU).

Table 1-3 AC power distribution

Power Device	Power Distribution Type	Circuit Breaker Specifications	Power-Consuming Device
ETP48200-A6	AC input	63 A/3 P x 1	N/A
	AC output	16 A/1 P x 1	AH3000
		16 A/1 P x 1	AH1500 or reserved
		20 A/1 P x 1	SOU or reserved

DC Power Distribution

The ETP48200-A6 in the Mini-shelter converts the AC power to -48 V DC power to providing power for the base station, transmission equipment, cooling equipment, storage batteries, and lamp.

Table 1-4 DC power distribution

Circuit Breaker Type	Circuit Breaker Specifications	Silkscreen	Power-Consuming Device
LLVD	80 A x 2	F1, F2	DCDU-12A in the BTS3900 (supplying power to RFUs, FAN 03C, BBUs, GATMs, and EMUA or EMUB).
BLVD	63 A x 1	F3	Transmission equipment, DCDU-12C^a, or reserved
	32 A x 1	F4	AH1500 or AH1500D
	16 A x 1	F5	AH3000
	16 A x 1	F6	PC500D
	16 A x 1	F7	Transmission equipment, lamp, or reserved
Battery disconnection	125 A x 2	-	Storage batteries
a: When the BLVD circuit breakers are insufficient, the DCDU-12C (supplying power to transmission equipment) must be configured.

1.4 Monitoring Principles

Alarm signals from the Mini-shelter and BTS3900 are reported to the BBU through an RS485 serial cable. Then, the BBU reports alarms to the U2000, allowing the U2000 to manage the Mini-shelter and BTS3900.

Monitoring Board Configuration

Customized alarms related to customer equipment are collected by the following boards:

USLP2 in the signal lightning protection unit (SLPU): The SLPU supports a maximum of two USLP2 boards, and each USLP2 supports a maximum of eight dry contact alarm signals.
EMUA/EMUB: It supports four analog monitoring signals and 32 dry contact alarm signals at most.

Therefore, an EMUA or EMUB is required when customized alarms are reported using analog signals, and related monitoring boards are required when customized alarms are reported using dry contacts. The following table lists the required boards for monitoring dry contact alarm signals.
