. The system will automatically calculate the corresponding relationship between CICs and the trunk circuits of the designated FTC. In BSC, 1 CIC can only correspond to 1 trunk circuit. During the interconnection of A interfaces, because the corresponding relationships between CICs and trunk circuits adopted by different manufacturers are slightly different, the corresponding relationship between each CIC and trunk circuit should be negotiated with MSC. Whether each timeslot of TFC occupies a CIC should also be negotiated with MSC. Generally, each timeslot should occupy a CIC.
Note: If "Auto Calculation" is selected in Figure 5-2, only the start CIC No. of the FTC configured in Slot2 of Frame4 can be modified. The other CICs are numbered sequentially from the start CIC No.

If the circuit state is "Unavailable", it indicates that the circuit is used to transmit signaling and sync. information. If the state is "Available", it indicates that the circuit is used for voice and data transmission. There are 32 circuits in each FTC. The 1st circuit is used to transmit sync. information. The circuit type is automatically configured as "A/PB Signaling Link", and the circuit state is "Unavailable". Because Port0 of the E3M in Figure 5-8 is configured with SS7 signaling, and Slot 16 of the E1 on MSM is used for SS7 signaling transmission, accordingly, Slot16 of each FTC in this TCSM is unavailable, as shown in Figure 5-12.

5.5 Manually Adjust A Interface Circuit Generally, A interface data need be manually adjusted during the establishment of new BSC office, or when a large-scale upgrade is performed for BSC. This subsection first introduces some concepts related to A interface circuits, and then describes the methods for manually adjusting A interface circuits.
5.5.1 Trunk Circuit I. Trunk circuit classification The trunk circuits of Abis interface and A interface are sequentially numbered within a BM in BSC. Abis interface circuits and A interface circuits can be differentiated by circuit type and trunk group. BSC automatically allocates 2 trunk groups to each BM. One is A interface trunk group, and the circuit type is TC. The other is Abis interface trunk group, and the 5-14
Initial Configuration M900/M1800 BSC Data Configuration Manual
Chapter 5 Trunk & Signaling Data of A Interface
circuit type is BIE. Here, take the full configuration of the BIE frame in BM1 as an example.
Figure 5-19 Full configuration of the BIE frame
II. Abis interface trunk group Abis interface trunk circuits are numbered as per BIEs. Each BIE group occupies 256 trunk circuit numbers. In Figure 5-19, the trunk circuits of BIE 0 are numbered from 0. BIE 16 is used to transparently transmit SS7. BIE groups 0~6 each occupy 8 HWs. BIE groups 7~8 each occupy 4 HWs. The trunk circuits of BM 1 that are numbered 0~1919 (256%7+128-1) are Abis interface trunk circuits. "256%7" denotes the number of circuits occupied by the first 7 BIE groups. "128" indicates that the 8th BIE group only uses 128 trunk circuits. 1 is subtracted because the trunk circuits are numbered from 0. The system automatically allocates 256 trunk circuit numbers to each BIE group. Therefore, The last 128 trunk circuit numbers (1920~2047) that the 7th BIE group corresponds to are not used. The trunk circuits numbered as 2048~2175 are the ones used by the BIE that transparently transmits SS7. Therefore, The last 128 trunk circuits numbered as 2176~2303 that the 8th BIE group corresponds to are also not used. Though only 1 timeslot is used to transmit a piece of SS7 message, the trunk circuits occupied by the BIE are all in unavailable states, and the circuit type is "A or Pb Interface Signaling Link", because the BIE cannot be used for other purposes. If two SS7 links are configured in the [E3M Board Property] interface, the BIE timeslots of the two signaling links must be different. Because FTC trunk circuits of are numbered after BIE trunk circuits, FTC numbers and circuit numbers will be changed after a BIE is delected, Therefore, BIE generally should not be deleted. For the BIE that is not in use, please configure it displayed in Figure 5-19 as invisible, so that it can not be viewed in BSC Maintenance System.
III. A interface trunk group The full configuration of TCSM frame is shown in Figure 5-20. 5-15
Initial Configuration M900/M1800 BSC Data Configuration Manual
Chapter 5 Trunk & Signaling Data of A Interface
Figure 5-20 Full configuration of TCSM frame Numbering of the trunk circuits of FTC starts from 2304. These trunk circuits respectively correspond to the CICs of A interface and the trunk circuits of E3M. Each FTC provides 32 trunk circuits. In Figure 5-20, the first TCSM unit in Frame4 contains 4 FTCs. The trunk circuit numbers for the 4 TFCs are 2304~2335, 2336~2367, 2368~2399 and 2400~2431 respectively (from left to right). The trunk circuits of the other 3 TCSM units in Frame4 are also sequentially numbered from left to right, and the No. range is 2432~2815. Likewise, the trunk circuits of the TCSMs in Frame5 are numbered as 2816~3327. All the trunk circuit numbers are automatically generated by the system, and need not be modified manually.
5.5.2 E3M Trunk Circuit Before and after an FTC trunk circuit is demultiplexed by MSM, the FTC trunk circuit No. is the same. One port on E3M corresponds to one TCSM unit. Therefore, there is a one-to-one relationship between FTC trunk circuits and E3M trunk circuit No.. The full configuration of the control frame in AM/CM is shown in Figure 5-21.
Figure 5-21 Full configuration of the control frame E3M trunk circuits in the whole BSC are sequentially numbered from 0. An E3M provides 512 trunk circuits. For example, No.0 E3M of Frame3 in Figure 5-21 corresponds to the 4 TCSM units of Frame4 in Figure 5-20, i.e. trunk circuits numbered as 2304~2815 correspond to E3M trunk circuits 0~511. No.1 E3M of 5-16
Initial Configuration M900/M1800 BSC Data Configuration Manual
Chapter 5 Trunk & Signaling Data of A Interface
Frame3 corresponds to the 4 TCSM units of Fame5 in Figure 5-20, i.e., trunk circuits numbered as 2816~3327 correspond to E3M trunk circuits 512~1023. E3M trunk circuit numbers are automatically generated by the system, and cannot be manually modified.
5.5.3 Manually Adjust CIC
Caution: Manual adjustment of CIC may lead to abnormal operation of the system. Make ensure that the CIC is correct.
Each trunk circuit of FTC may correspond to a CIC. CIC must be unique, and should be determined based on negotiation with MSC. The “5.2 Relationship between CICs and Trunk Circuits” subsection has described how the corresponding relationship between CICs and trunk circuits is automatically generated by the system or is manually adjusted. This part will focus on how to manually modify the corresponding relationship between CICs and FTC trunk circuits. Deselect "Auto Calculation" in the [A-Interface Timeslot Occupancy] tab page as shown in Figure 5-2. Then double click an FTC to pop up the [Set FTC Board Property] interface, and select the [Basic Information] tab page, as shown in Figure 5-22.
Figure 5-22 Basic Information 5-17
Initial Configuration M900/M1800 BSC Data Configuration Manual
Chapter 5 Trunk & Signaling Data of A Interface
Deselect "Auto-Calculate Circuit Property", and then select the [Circuit Property] tab page, as shown in Figure 5-23.
Figure 5-23 Circuit Property In the [Circuit Property] tab page, [State], [CIC] and [Circuit Type] of each trunk circuit of the FTC can be modified. [State] can be set as "Unavailable", "Available" or "Block". [Circuit Type] can be set as "A Traffic Link", "A/PB Signaling Link" or "A Maintenance Link". CIC can be directly input. Trunk circuit 0 of FTC must be used to transmit sync. signals. The state is "Unavailable", and the circuit type is "A/PB Signaling Link". The trunk circuit for SS7 signaling transmission must be consistent with the one in MSC. The state of it is "Unavailable", and the circuit type is "A/PB Signaling Link". The signaling timeslots on MSM are fixedly demultiplexed to the corresponding timeslots of the 4 corresponding FTCs. Therefore, if trunk circuit 16 of FTC 0 in a TCSM unit is used to transmit SS7 signaling, the same configuration must be adopted for trunk circuit 16 of the other 3 FTCs. [MSM TS] must be configured in consistency with that in Figure 5-8. Trunk circuit 31 of the last FTC in each TCSM unit must be configured as "A Maintenance Link", and [State] should be configured as "Unavailable".

5.5 Manually Adjust A Interface Circuit Generally, A interface data need be manually adjusted during the establishment of new BSC office, or when a large-scale upgrade is performed for BSC. This subsection first introduces some concepts related to A interface circuits, and then describes the methods for manually adjusting A interface circuits.
5.5.1 Trunk Circuit I. Trunk circuit classification The trunk circuits of Abis interface and A interface are sequentially numbered within a BM in BSC. Abis interface circuits and A interface circuits can be differentiated by circuit type and trunk group. BSC automatically allocates 2 trunk groups to each BM. One is A interface trunk group, and the circuit type is TC. The other is Abis interface trunk group, and the 5-14
Initial Configuration M900/M1800 BSC Data Configuration Manual
Chapter 5 Trunk & Signaling Data of A Interface
circuit type is BIE. Here, take the full configuration of the BIE frame in BM1 as an example.
Figure 5-19 Full configuration of the BIE frame
II. Abis interface trunk group Abis interface trunk circuits are numbered as per BIEs. Each BIE group occupies 256 trunk circuit numbers. In Figure 5-19, the trunk circuits of BIE 0 are numbered from 0. BIE 16 is used to transparently transmit SS7. BIE groups 0~6 each occupy 8 HWs. BIE groups 7~8 each occupy 4 HWs. The trunk circuits of BM 1 that are numbered 0~1919 (256%7+128-1) are Abis interface trunk circuits. "256%7" denotes the number of circuits occupied by the first 7 BIE groups. "128" indicates that the 8th BIE group only uses 128 trunk circuits. 1 is subtracted because the trunk circuits are numbered from 0. The system automatically allocates 256 trunk circuit numbers to each BIE group. Therefore, The last 128 trunk circuit numbers (1920~2047) that the 7th BIE group corresponds to are not used. The trunk circuits numbered as 2048~2175 are the ones used by the BIE that transparently transmits SS7. Therefore, The last 128 trunk circuits numbered as 2176~2303 that the 8th BIE group corresponds to are also not used. Though only 1 timeslot is used to transmit a piece of SS7 message, the trunk circuits occupied by the BIE are all in unavailable states, and the circuit type is "A or Pb Interface Signaling Link", because the BIE cannot be used for other purposes. If two SS7 links are configured in the [E3M Board Property] interface, the BIE timeslots of the two signaling links must be different. Because FTC trunk circuits of are numbered after BIE trunk circuits, FTC numbers and circuit numbers will be changed after a BIE is delected, Therefore, BIE generally should not be deleted. For the BIE that is not in use, please configure it displayed in Figure 5-19 as invisible, so that it can not be viewed in BSC Maintenance System.
III. A interface trunk group The full configuration of TCSM frame is shown in Figure 5-20. 5-15
Initial Configuration M900/M1800 BSC Data Configuration Manual
Chapter 5 Trunk & Signaling Data of A Interface
Figure 5-20 Full configuration of TCSM frame Numbering of the trunk circuits of FTC starts from 2304. These trunk circuits respectively correspond to the CICs of A interface and the trunk circuits of E3M. Each FTC provides 32 trunk circuits. In Figure 5-20, the first TCSM unit in Frame4 contains 4 FTCs. The trunk circuit numbers for the 4 TFCs are 2304~2335, 2336~2367, 2368~2399 and 2400~2431 respectively (from left to right). The trunk circuits of the other 3 TCSM units in Frame4 are also sequentially numbered from left to right, and the No. range is 2432~2815. Likewise, the trunk circuits of the TCSMs in Frame5 are numbered as 2816~3327. All the trunk circuit numbers are automatically generated by the system, and need not be modified manually.
5.5.2 E3M Trunk Circuit Before and after an FTC trunk circuit is demultiplexed by MSM, the FTC trunk circuit No. is the same. One port on E3M corresponds to one TCSM unit. Therefore, there is a one-to-one relationship between FTC trunk circuits and E3M trunk circuit No.. The full configuration of the control frame in AM/CM is shown in Figure 5-21.
Figure 5-21 Full configuration of the control frame E3M trunk circuits in the whole BSC are sequentially numbered from 0. An E3M provides 512 trunk circuits. For example, No.0 E3M of Frame3 in Figure 5-21 corresponds to the 4 TCSM units of Frame4 in Figure 5-20, i.e. trunk circuits numbered as 2304~2815 correspond to E3M trunk circuits 0~511. No.1 E3M of 5-16
Initial Configuration M900/M1800 BSC Data Configuration Manual
Chapter 5 Trunk & Signaling Data of A Interface
Frame3 corresponds to the 4 TCSM units of Fame5 in Figure 5-20, i.e., trunk circuits numbered as 2816~3327 correspond to E3M trunk circuits 512~1023. E3M trunk circuit numbers are automatically generated by the system, and cannot be manually modified.
5.5.3 Manually Adjust CIC
Caution: Manual adjustment of CIC may lead to abnormal operation of the system. Make ensure that the CIC is correct.
Each trunk circuit of FTC may correspond to a CIC. CIC must be unique, and should be determined based on negotiation with MSC. The “5.2 Relationship between CICs and Trunk Circuits” subsection has described how the corresponding relationship between CICs and trunk circuits is automatically generated by the system or is manually adjusted. This part will focus on how to manually modify the corresponding relationship between CICs and FTC trunk circuits. Deselect "Auto Calculation" in the [A-Interface Timeslot Occupancy] tab page as shown in Figure 5-2. Then double click an FTC to pop up the [Set FTC Board Property] interface, and select the [Basic Information] tab page, as shown in Figure 5-22.

Deselect "Auto-Calculate Circuit Property", and then select the [Circuit Property] tab page, as shown in Figure 5-23.
Figure 5-23 Circuit Property In the [Circuit Property] tab page, [State], [CIC] and [Circuit Type] of each trunk circuit of the FTC can be modified. [State] can be set as "Unavailable", "Available" or "Block". [Circuit Type] can be set as "A Traffic Link", "A/PB Signaling Link" or "A Maintenance Link". CIC can be directly input. Trunk circuit 0 of FTC must be used to transmit sync. signals. The state is "Unavailable", and the circuit type is "A/PB Signaling Link". The trunk circuit for SS7 signaling transmission must be consistent with the one in MSC. The state of it is "Unavailable", and the circuit type is "A/PB Signaling Link". The signaling timeslots on MSM are fixedly demultiplexed to the corresponding timeslots of the 4 corresponding FTCs. Therefore, if trunk circuit 16 of FTC 0 in a TCSM unit is used to transmit SS7 signaling, the same configuration must be adopted for trunk circuit 16 of the other 3 FTCs. [MSM TS] must be configured in consistency with that in Figure 5-8. Trunk circuit 31 of the last FTC in each TCSM unit must be configured as "A Maintenance Link", and [State] should be configured as "Unavailable".

7.3 Tree Networking Data Configuration 7.3.1 Tree Networking Tree networking is to connect 2 or more lower-level sites to an upper level site. It is an expansion mode for chain networking. The tree networking includes 5 trunk modes. 2E1Port*Full-Rate 64KLAPD/Port 2E1 Port*Semi-Rate 32KLAPD Multiplexing Mode/Port 2E1 Port*15:1 Multiplexing Mode/Port Analog 12:1 Analog 10:1 To describe tree networking configuration, here, take "2E1 Port*Full-Rate 64KLAPD/Port" as an example. In the example, the connection between an upper level site and 2 lower level sites will be configured.
I. Configure chain connection Configure a single chain which contains 2 sites. Site0 is the upper level site and Site1 the lower level site. Refer to 7.2.1 Chain Networking Configuration—Single
Chain for the configuration procedure. Figure 7-27 shows the result of single chain networking configuration.

7.3.2 Star Cascade It is a combination mode of star networking and chain networking for star cascade networking. There are 2 BIE trunk modes that star cascade. 6E1 Port*2TRX/Port ( Link) 4E1 Port*6TRX/Port ( Link) Because "4E1 Port*6TRX/Port" is more widely adopted, here, take this networking mode as an example.
I. Configure star networking First perform configuration as per star networking. Select "4E1 Port*6TRX/Port ( Link)"as the trunk mode, as shown in Figure 7-30.

When different types of BTSs, e.g. BTS22C and BTS30, are configured on the same chain, it is need to adjust manually timeslots.
II. Operation Procedure If timeslots need to be manually adjusted, the fill-up of timeslot data should be performed as per the timeslot allocation in each networking mode described in the appendix. The specific procedure is as follows.
1) 2)
Configure the basic data in the non-manual adjustment mode. Click
