Adding BTS Modules

This describes how to add modules other than RF modules for the DBS3900, BTS3900, and BTS3900A, including the APMU, DTCU, FMUA, FMU, DEMU, and GATM.

Preparation

Table 1 lists the mandatory module types to be added and mandatory slot numbers to be configured for BTSs of different types. Table 2 lists the optional module types to be added and optional slot numbers to be configured for BTSs of different types.

Table 1 Mandatory BTS module types

Site Type	Module Type	Available Slot Number	Mapping Physical Module
DBS3900 GSM (outdoor)	APMU	2, 3	PMU module and APMI/HPMI
	DTCU	6, 7, 18, 19	AFMU/HEUA
DBS3900 GSM/UMTS (outdoor)	APMU	3	PMU module and APMI/HPMI
	DTCU	7	AFMU/HEUA
BTS3900 GSM BTS3900 GSM/UMTS	FMU	8-11	Fan board
BTS3900A GSM	APMU	2, 3	PMU module and APMI/HPMI
	DTCU	6, 7, 18, 19	AFMU/HEUA
	FMUA	8-11	FMUA
BTS3900A GSM/UMTS	APMU	3	PMU module and APMI/HPMI
	DTCU	7	AFMU/HEUA
	FMUA	8-11	FMUA

NOTE:

When the APM monitoring signal is transmitted to the RRU through the alarm cable, the APMU and DTCU should be configured in the slot shown in the red rectangular in Figure 1. When the APM monitoring signal is transmitted to the BBU through the alarm cable, the APMU and DTCU should be configured in subrack 2 in Figure 1.

Table 2 Optional BTS module types

Site Type	Module Type	Available Slot Number	Configuration Conditions	Mapping Physical Module
DBS3900 GSM (indoor) DBS3900 GSM/UMTS (indoor) DBS3900 GSM (outdoor) DBS3900 GSM/UMTS (outdoor) BTS3900 GSM BTS3900 GSM/UMTS BTS3900A GSM BTS3900A GSM/UMTS	DEMU	0, 1	When the Boolean values provided by the existing UPEU and UEIU cannot meet the requirements of the telecom equipment room, you need to add the DEMU.	EMUA
	GATM	16, 17	When the BTS of a new GSM site is configured with the RET antenna or TMA, you need to add the GATM. When the GSM BTS of a new GSM/UMTS site is configured with the RET antenna or TMA, you do not need to add the GATM. The RET antenna and TMA are monitored on the UMTS side.	GATM

NOTE:

On a GSM/UMTS site, the RET antenna and TMA can be monitored on the UMTS side. When a GSM site is upgraded to a GSM/UMTS site, the RET antenna and TMA of the previous GSM site are still monitored by the GATM. That is, on the LMT, you do not need to delete the configuration of the GATM.

Procedure

1. Add the APMU.
   1. In subrack 2 in the "Site Device Attributes" dialog box, right-click the corresponding slot as described in Table 1. A shortcut menu is displayed, as shown in Figure 2.

   5. Set Board Parameter Configuration Enabled to Yes and configure parameters listed in Table 3. If a battery cabinet is configured, set Battery Cabinet Configuration Enabled to Yes.

      Table 3 APMU parameters to be configured

      Board Parameter Configuration	Battery Cabinet Configuration
      APMU Board Application Scenario DPSU 0 DPSU 1 DPSU 2	Battery Type Charge Coefficient Battery Capacity

      CAUTION:

      The parameters related to the battery cabinet must be configured in accordance with the actual situation. Otherwise, the battery cabinet cannot work properly.

   6. After the configuration is complete, click OK to return to the Site Device Attributes dialog box.
2. Add the DTCU.
   1. In subrack 2 in the "Site Device Attributes" dialog box, right-click the corresponding slot as described in Table 1. A shortcut menu is displayed, as shown in Figure 5.

      Feed Tributary 0 Alarm Mode	Set this parameter to Mode1, Mode2, or Mode3. Mode 1: In this mode, there is only one alarm severity. The current for alarming is constant and higher than the normal operating current. Mode 2: In this mode, there are two alarm severities: warning alarm and critical alarm. The current for alarming is constant and higher than the normal operating current. Mode 3: In this mode, there are two alarm severalties: warning alarm and critical alarm. The current for reporting a warning alarm is a periodic pulse. The current for reporting a critical alarm is a constant current.
      Feed Tributary 0 TMA Configuration	Set this parameter to Disabled or Enabled.
      Feed Tributary 0 Upper Threshold for TMA Current Critical Alarm	The value range of this parameter is [0, 2000]. The default value is 170.
      Feed Tributary 0 Upper Threshold for TMA Current Warning	The value range of this parameter is [0, 2000]. The default value is 170.
      Feed Tributary 0 Lower Threshold for TMA Current Alarm	The value range of this parameter is [0, 2000]. The default value is 30.
