1 OverviewThe BTS3X Base Transceiver Station support 24 extended switching value/digital inputs, 8 digital outputs, 8 analog inputs, access of EAC and access of PIB power inspection board. The corresponding physical ports are EAC1 (DB37 female) and EAC2 (DB25 female) on the TDU. The BTS3X Base collects the external alarm signals and controls the external equipment over EAC1 and EAC2. It must be pointed out that EAC is different from the extended alarm though it shares the EAC2 connector with the extended alarm. EAC connects to TMU for communication by linking EAC2 pin and the bus CBUS3 on TMU. While the extended alarm signals are switching value signals. For description simplification, 24-extended switching/digit values are called 24-extended alarm for short. 24-extended switching/digit inputs, 8 digit outputs, 8 analog inputs, EAC signals, PIB power inspection signals are called alarm signals for short.

2 Connections of Extended Alarm Signals2.1 Connections of Extended Alarm SignalsBoth the digital analog input and output are transferred via conductor layout cables to the CMB over the cabinet top, and then to the TMU via hardware linker between CMB and TMU. TMU provides the function of alarm collection and signal output. The specific connections are given below.

1) TMU->CMB: TMU connects to CMB by linking the 96PIN DIN connector XD1 (female) on TMU and the 96PIN DIN connector XD1/XD2 (male) on CMB.

2) CMB->TDU: CMB transits the 24 digital inputs and the 8 digital outputs from CMB.XD1/CMB.XD2 to the 40PIN D-connector CMB.J20, and transits the 8 analog inputs from CMB.XD1/CMB.XD2 to the 14PIN D-connector JP21. With two pairs of 120( twisted-pair cables (04028314-V0 and 04028304-V0), the CMB transits the 24 digital inputs and the 8 digital outputs to the 40PIN D-connector TDU.JP17, and the 8 analog inputs to the 14PIN D-connector TDU.JP19.

3) TDU->EAC1/EAC2: TDU transits via its PCB layout the 24 digital inputs and the 8 digital outputs TDU.JP17 and the 8 analog input on TDU.JP19 to the BTS external interfaces EAC1 (TDU.JP16) and EAC2 (TDU.JP18).

Figure 1 shows connection of EAC1 and EAC2 on TDU:

Figure 1 Extended alarm cable connection inside the cabinetFigure 2 and Figure 3 show EAC1 pins and EAC2 pins on the TDU.

Figure 2 EAC2 pinsThe pins in blue are 15 signal pins of the 24-extended alarm signal pins. The green are grounding cables. The black are pins connected to CBUS3 of EAC.

The red in Table 1 indicates the 24 extended alarm pins distributed on EAC1 and EAC2.

On EAC2, there are extended alarm pins as well as four EAC pins (CBUS3_TD+/-, CBUS3_RD+/-). Therefore, it is necessary to perform signal branching at EAC2 if the BTS connects to both EAC and 24 switching value/digital inputs.2.2 Networking of 24-Extended Alarm Signals, EAC Signals and PIB Power inspection boardFigure 4 shows the planform of the cabinet. EAC1 and EAC2 are ports used to connect signals.

Figure 4 Planform of the cabinetNote: All signal cables from/to EAC1 must pass over EAC signal arrester to ensure operation security. The external alarm signals above have several forms of combination, as given below:1.Connect only 24-extended alarm:If there are over than one but less than nine alarm signals, you can connect a private cable to EAC1.

If there are over nine but less than 15 alarm signals, you can connect a private cable to EAC2.

If there are more than 15 alarm signals, you must connect two private cables to EAC1 and EAC2 respectively. Both cables are designed specially for 24-extended alarm, and they can extend 24 signal braches and the corresponding PGND cables. One end of such a cable is a DB connector, connecting to EAC lightning protector, and the other end is naked, connecting to the extended alarm socket in DDF. External alarm input cables are connected to the other side of extended alarm socket in DDF, as shown in Figure 5.

Figure 5 Connection of 24-extended alarm 2. Connect only EAC:Connect the private communication cable of EAC to EAC2 (DB25). Connect both power cable and grounding cable of EAC to the cabinet top. For details, please refer to description of EAC in BTS Lightening Protection Retrofit Guide (BTS3X)V2. Figure 6 shows the corresponding connection schemes:

Figure 6 Connection of EAC3. Connect only PIB power inspection board:Connect PIB signal cable to the EAC1 port of the cabinet. For details, please refer to GSM BTS3X GM51PIB Power Inspection Board Installation Manual V3.0. Figure 7 shows the connection of PIB power inspection board:

Figure 7 Connection of PIB power inspection board 4. Connect 24-Extended Alarm and EAC:

Figure 8 Connection of 24-extended alarm and EACSince the EAC2 port is multiplexed by both EAC interface and 24-extended alarm interface, it is necessary to use a DB25 three-way adapter. If there are less than 9 channels of extended alarm signals, they can connect to EAC1 instead of EAC2.5. Connect 24-extended alarm and PIB

Figure 9 Connection of 24-extended alarm and power inspection board (PIB) Since PIB power inspection board connects to two of the 24 channels of extended alarm signals, you can connect the communication cable of the PIB module to the extended alarm socket in DDF.If there are less than 15 channels of extended alarm signals, you can connect PIB signal cable to EAC1 directly, and extended alarm cable to EAC2.6. Connect EAC and PIB:EAC connects to EAC2 port, and PIB connects to EAC1 port.7. 24-extended alarm, EAC and PIB

Figure 10 Connection of 24-extend alarm, EAC and PIBIf there are over 15 channels of extended alarm signals, the cable connection is shown in Figure 10.If there are less than 9 channels of extended alarm signals and PIB module signals, you can connect only one 24-extended alarm cable to EAC1 port, and EAC communication cable to EAC2 port. The DB25 three-way adapter is unnecessary for EAC2 port in this case.2.3 Materiel for Extended Alarm Connection1. EAC lightning protectorEAC lightning protector (DB25 and DB37): One end of the EAC is a pin, and the other end is a jack.

When installing EAC, fix the end with a pin on the NodeB EAC port, and then fasten the screws at both sides to ensure connection reliability. Any EAC must be installed with a lightening arrester to ensure operation security.2. T-shape three-way DB25 adapter T-shape three way DB25 adapter supports PIN-TO-PIN connection. It presents two DB25 female connectors that are the same to the previous EAC2 pins for EAC2 port.3. 24-extended alarm cableTwo cables are necessary for 24-extended alarm signals distributed at EAC1 and EAC2. In DB25 connector, there are 15 signal cables and three signal PGND cables. The three signal PGNDs extend 12 branches to match with the 15 signal cables. There are nine signal cables and two PGND cables in a DB37 connector. The two PGND cables extend seven braches to match with the nine signal cables.4. DDFDDF in Figure 10 is numbered 02080654 and 02080655, which is the new version designed in 2003. By default, there are no extended alarm sockets in DDF. If it is necessary to support extended alarm connection, the alarm socket numbered 02080656 must be presented in delivery.There are alarm sockets in the DDF of earlier versions, numbered 02080237, but they are not optimized specially for 24-extended alarm signals.2.4 Materiel of Extended Alarm InterfaceTable 2 Materiel of Extended Alarm InterfaceExtended AlarmExtended AlarmEnvironment MonitorExtended AlarmPIB-Power Inspection BoardExtended AlarmEnvironment MonitorExtended AlarmPIB-Power Inspection BoardPIB-Power Inspection BoardEnvironment MonitorExtended AlarmPIBEnvironment Monitor

2.5 EAC lightning protector Configuration1) 24-extended alarm, EAC and PIB are all configured in EAC lightning protector.2) For BTSs setup before, there are no EAC lightning protector.

Operation instructions: firstly, clarify the importance of EAC lightning protector; secondly, persuade the office party to purchase the corresponding EAC lightning protector; thirdly, if the office party has no plan to buy the EAC lightning protector, inform the office party of possible accidents and reliabilities, and subscribe the corresponding memo about it. Fourthly, present an EAC lightning protector to the office part if fail to subscribe the memo with the office party.

3 Support of Software3.1 Support Only 8 Switching Value InputsThe earlier versions of TMU G3BTS32.30002.01.1130 and BSC G3BSC V300R00210101B04D1120A support only 8 switching value/digital inputs. Three of them are for BTS30A specially and the rest are for user-defined extended alarms, as shown in the table below.Software-hardware correspondence of 8 switching value inputsNoAlarm nameSignalSignal earthAlarm value

3.2 Commentary to supporting 24 switching value inputsIt is only for BTS30 and BTS312.4.2.1 Declaration for 24 Switching Values of EACTMU software version G3BTS32.30002.01.1130 and BSC software version V300R00210101B04D1120A and their subsequent versions support 24 extended digital signal inputs. The 24 digital signal inputs can all be used as user-defined pin. Since the extended digital signal inputs may be used a great lot, the EAC1 interface is recommended when there are less than 9 extended signal inputs, and the EAC2 interface is used first when there are more than 9 but less than 14 extended signal inputs.Software-hardware correspondence of 24 switching value inputsNo.Alarm nameAlarm IDSignalSignal earth

Note: The parameter EAC2/8 represents pin 8 of EAC2 on the TDU. The rest may be deduced by analogy.

Whether the alarm is of high-voltage or low-voltage can be set through assigning values for [alarm level byte 1], [alarm level byte 2] and [alarm level byte 3] in [Site's Extended Parameter]. Likewise, each bit of the three parameters corresponds to an extended digital input. List of alarm level bytesBit76543210
