Overview

2.1 Introduction The BTS Combined Cabinets and Cabinet Groups feature is introduced to increase BTS capacity. In traffic-heavy urban areas, telecom operators want to deploy large-capacity BTSs to reduce the quantity of BTSs and therefore save construction and maintenance costs. Each BTS cabinet, however, can accommodate a limited number of TRXs. For example, a single BTS3012 cabinet can accommodate a maximum of 12 TRXs. This means that a single BTS cabinet cannot meet the requirements of telecom operators. The BTS Combined Cabinets and Cabinet Groups feature addresses this problem. For example, with this feature, a BTS3012 is expanded to have three cabinet groups (each group comprises two combined cabinets) and can support up to 72 TRXs. The BTS Combined Cabinets and Cabinet Groups feature applies to areas with heavy traffic and a high construction and maintenance cost. l

BTS Combined Cabinet: applies when a single cabinet cannot meet the large capacity requirement.

l

BTS Hybrid Cabinet Group: applies if combined cabinets still cannot meet the capacity requirement.

With the BTS Combined Cabinet feature, multiple BTS cabinets of the same type are combined by using signal cables. The combined cabinets function as one BTS. One of the combined cabinets provides transmission interfaces and implements operation and maintenance (OM) for all the combined cabinets. This cabinet is called the basic cabinet, and the other cabinets are called extension cabinets. The main control board in the basic cabinet is connected to a BSC through a transmission cable. This board receives traffic signals, signaling, OM signals, and clock synchronization signals from the BSC through the transmission cable. The board then distributes the signals and signaling to the TRXs in the basic cabinet through the internal bus and to the TRXs in the extension cabinets through the cables for the combined cabinets. In this manner, services and OM of all the TRXs in the combined cabinets are synchronized. With the BTS Hybrid Cabinet Group feature, multiple combined cabinets are grouped by using signal cables. The cabinet groups function as one BTS. One of the cabinet groups provides clock synchronization signals and OM signals for all the cabinet groups. This cabinet group is called the basic cabinet group, and the other cabinet groups Issue 01 (2013-05-06)

2 Overview

are called extension cabinet groups. The main control board of the basic cabinet in the basic cabinet group receives traffic signals, signaling, OM signals, and clock synchronization signals from the BSC through the transmission cable. The main control board of the basic cabinet in each extension cabinet group, however, extracts only traffic signals and signaling from the transmission cable. The main control board of the basic cabinet in each extension cabinet group obtains OM signals and clock synchronization signals from the main control board of the basic cabinet in the basic cabinet group through the signal cables for cabinet groups. In this manner, services and OM of all the TRXs in the cabinet groups are synchronized. A cabinet group can be one basic cabinet or two combined cabinets. A cabinet group that provides synchronization clock signals is called a basic cabinet group. Other cabinet groups are called extension cabinet groups. The basic cabinet of each cabinet group can be configured with one or two DTMUs. Combined cabinets and cabinet groups are distinguished in cabinet numbers. Three consecutive combined cabinets form one cabinet group. The basic cabinet group is comprised of cabinets 0 to 2, extension cabinet group 1 is comprised of cabinets 3 to 5, and extension cabinet group 2 is comprised of cabinets 6 to 8. The BTS3012 supports a maximum of two combined cabinets and three cabinet groups. The corresponding cabinet numbers are as follows: l

Basic cabinet group: cabinets 0 and 1

l

Extension cabinet group 1: cabinets 3 and 4

l

Extension cabinet group 2: cabinets 6 and 7

As shown in Figure 2-1, one BTS consists of three cabinet groups: one basic cabinet group and two extension cabinet groups. The cabinet groups are connected to each other through signal cables for cabinet groups. Each cabinet group consists of two cabinets: one basic cabinet and one extension cabinet. The cabinets are connected to each other through the signal cables for combined cabinets. Figure 2-1 Combined cabinets and cabinet groups

Technical Description

3.1 Combined Cabinets and Cabinet Groups of the BTS3012 One BTS3012 cabinet supports a maximum of 12 TRXs. If a synchronous cell requires more than 12 TRXs, combined cabinets can be used. One BTS3012 supports up to 2 combined cabinets and 3 cabinet groups. Two combined BTS3012 cabinets compose a cabinet group to support a maximum of 24 TRXs. Three cabinet groups are combined to support up to 72 TRXs.

Implementation of Combined Cabinets Figure 3-1 shows the connection of BTS3012 combined cabinets. Among the combined cabinets, only the basic cabinet must be configured with the DTMU. The DTMU is connected to a BSC through a transmission cable and receives traffic signals, signaling, OM signals, and clock synchronization signals from the BSC through the transmission cable. The DTMU then distributes the signals and signaling to the TRXs in the basic cabinet through the internal bus and to the TRXs in the extension cabinet through the signals cables for combined cabinets. As a result, services and OM of all the TRXs in the combined cabinets are synchronized. Figure 3-1 Connection of the combined cabinets

Implementation of Cabinet Groups Figure 3-2 shows the connections of BTS3012 cabinet groups. The basic cabinet in each cabinet group must be configured with the DTMU. The DTMU in the basic cabinet of the basic cabinet group receives traffic signals, signaling, OM signals, and clock synchronization signals from the BSC through the transmission cable. The DTMU in the basic cabinet of each extension cabinet group, however, extracts only traffic signals and signaling from the transmission cable. Issue 01 (2013-05-06)

The DTMU in the basic cabinet of each extension cabinet group obtains OM signals and clock synchronization signals from the DTMU in the basic cabinet of the basic cabinet group through the signal cables for cabinet groups. In this manner, services and OM of all the TRXs in the cabinet groups are synchronized. Figure 3-2 Connections of the cabinet groups

3.2 Combined Cabinets and Cabinet Groups of the BTS3006C One BTS3006C cabinet supports a maximum of six TRXs. If a synchronous cell requires more than six TRXs, combined cabinets can be used. One BTS3006C supports a maximum of six combined cabinets but does not support cabinet groups. The combined cabinets of BTS3006C support up to 36 TRXs. The DMCM, which has two small form-factor pluggable (SFP) optical ports: SFP-A and SFPB, functions as the main control board in a BTS3006C. The two ports are used to connect combined cabinets and can be used interchangeably. For example, if cabinet 0 must be connected to cabinet 1 through an optical cable, the optical cable can be connected to the SFP-A or SFPB optical port of cabinet 1. If one SFP optical port of cabinet 1 is connected to cabinet 0, the other SFP optical port of cabinet 1 can be connected to any SFP optical port of cabinet 2. When implementing combined cabinets, the hardware configuration of the BTS3006C basic cabinet is the same as that of each BTS3006C extension cabinet. Both the basic and extension cabinets are configured with the DMCM. The settings of DIP switches differentiate the basic cabinet from an extension cabinet. Combined cabinets use the chain or ring topology.

Implementation of the Combined Cabinets in the Chain Topology Figure 3-3 shows the connections of combined cabinets in the chain topology. Cabinet 0 is the basic cabinet. The DMCM in the basic cabinet is connected to a BSC through a transmission cable. The DMCM receives traffic signals, signaling, OM signals, and clock synchronization signals from the BSC through the transmission cable. The DMCM then distributes the signals and signaling to the TRXs in the basic cabinet through the internal bus and to the TRXs in the extension cabinets through the signal cables for combined cabinets. In this manner, services and OM of all the TRXs in the combined cabinets are synchronized.

Figure 3-3 Connections of combined cabinets in the chain topology

Implementation of Combined Cabinets in the Ring Topology Figure 3-4 shows the connections of combined cabinets in the ring topology. In the ring topology, the dual-ring backup technology is adopted. With this technology, signals of combined cabinets are transmitted on both the forward and reverse rings. By default, signals are transmitted on the forward ring in the following sequence: cabinet 0, 1, 2, 3, 4, and 5. When the transmission on the forward ring is interrupted, the forward ring is automatically switched to the reverse ring and signals are transmitted on the reverse ring in the following sequence: cabinet 0, 5, 4, 3, 2, and 1. Combined cabinets in the ring topology are more reliable and robust than those in the chain topology. As shown in Figure 3-4, cabinet 0 is the basic cabinet. The DMCM in the basic cabinet is connected to a BSC through a transmission cable. The DMCM receives traffic signals, signaling, OM signals, and clock synchronization signals from the BSC. The DMCM then distributes the signals and signaling to the TRXs in the basic cabinet through the internal bus and to the TRXs in the extension cabinets through the signal cables for combined cabinets. In this manner, services and OM of all the TRXs in the combined cabinets are synchronized. Figure 3-4 Connections of combined cabinets in the ring topology

3.3 Combined Cabinets and Cabinet Groups of the BTS3002E One BTS3002E cabinet supports a maximum of two TRXs. If a synchronous cell requires more than two TRXs, combined cabinets can be used. One BTS3002E supports a maximum of six Issue 01 (2013-05-06)

combined cabinets but does not support cabinet groups. The combined cabinets of BTS3002E support up to 12 TRXs. The DMCM, which has two SFP optical ports: SFP-A and SFP-B, functions as the main control board in a BTS3002E. The two ports are used to connect combined cabinets and can be used interchangeably. For example, if cabinet 0 must be connected to cabinet 1 through an optical cable, the optical cable can be connected to the SFP-A or SFP-B optical port of cabinet 1. If one SFP optical port of cabinet 1 is connected to cabinet 0, the other SFP optical port of cabinet 1 can be connected to any SFP optical port of cabinet 2. When implementing combined cabinets, the hardware configuration of the BTS3002E basic cabinet is the same as that of each BTS3002E extension cabinet. Both the basic and extension cabinets are configured with the DMCM. The settings of DIP switches differentiate the basic cabinet from an extension cabinet. Combined cabinets use the chain or ring topology.

Implementation of the Combined Cabinets in the Chain Topology Figure 3-5 shows the connections of combined cabinets in the chain topology. Cabinet 0 is the basic cabinet. The DMCM in the basic cabinet is connected to a BSC through a transmission cable. The DMCM receives traffic signals, signaling, OM signals, and clock synchronization signals from the BSC through the transmission cable. The DMCM then distributes the signals and signaling to the TRXs in the basic cabinet through the internal bus and to the TRXs in the extension cabinets through the signal cables for combined cabinets. In this manner, services and OM of all the TRXs in the combined cabinets are synchronized. Figure 3-5 Connections of combined cabinets in the chain topology

Implementation of Combined Cabinets in the Ring Topology Figure 3-5 shows the connections of combined cabinets in the ring topology. In the ring topology, the dual-ring backup technology is adopted. With this technology, signals of combined cabinets are transmitted on both the forward and reverse rings. By default, signals are transmitted on the forward ring in the following sequence: cabinet 0, 1, 2, 3, 4, and 5. When the transmission on the forward ring is interrupted, the forward ring is automatically switched to the reverse ring and signals are transmitted on the reverse ring in the following sequence: cabinet 0, 5, 4, 3, 2, and 1. Combined cabinets in the ring topology are more reliable and robust than those in the chain topology. As shown in Figure 3-6, cabinet 0 is the basic cabinet. The DMCM in the basic cabinet is connected to a BSC through a transmission cable. The DMCM receives traffic signals, signaling, OM signals, and clock synchronization signals from the BSC. The DMCM then distributes the signals and signaling to the TRXs in the basic cabinet through the internal bus and to the TRXs Issue 01 (2013-05-06)

in the extension cabinets through the signal cables for combined cabinets. In this manner, services and OM of all the TRXs in the combined cabinets are synchronized. Figure 3-6 Connections of combined cabinets in the ring topology

3.4 Hybrid Cabinet Groups of the BTS3012 and BTS3X The BSC6910 does not support hybrid cabinet groups of the BTS3012 and BTS3X. BTS3012, BTS30, and BTS312 cabinets can form hybrid cabinet groups. The cabinets in a basic cabinet group must be BTS3012 cabinets. The cabinets in an extension cabinet group can be BTS30 or BTS312 cabinets. In BTS3012 and BTS30 hybrid cabinet groups, one extension cabinet group consists of a maximum of 3 combined cabinets; therefore, the hybrid cabinet groups support up to 60 TRXs (each BTS30 cabinet supports a maximum of six TRXs). In BTS3012 and BTS312 hybrid cabinet groups, one extension cabinet group consists of a maximum of 2 combined cabinets; therefore, the hybrid cabinet groups support up to 72 TRXs (each BTS312 cabinet supports a maximum of 12 TRXs). The characteristics and limitations of hybrid cabinet groups are as follows: l

Hybrid cabinet groups can have at most two types of cabinets. The cabinets in a basic cabinet group must be BTS3012 cabinets. The cabinets in an extension cabinet group can be BTS30 or BTS312 cabinets.

l

The TRXs in the cabinets of different types can be configured for one cell. The TRXs serving one cell can be located in BTS3012 and BTS30 hybrid cabinet groups or in BTS3012 and BTS312 hybrid cabinet groups.

l

Cabinets of different BTS types can be configured as cabinet groups but cannot be combined. That is, a BTS3012 cabinet cannot be combined with a BTS30 or BTS312 cabinet.

Figure 3-7 shows the connections between a BTS3012 basic cabinet group and two BTS30 extension cabinet groups.

Engineering Guidelines

The configuration principles of combined cabinets and cabinet groups are as follows: l

Minimal antennas The number of antennas should be as few as possible to reduce costs.

l

Minimal cabinets The number of cabinets should be as few as possible to reduce costs.

l

Complete synchronous directional cell All the TRXs of one synchronous directional cell should be configured in one cabinet to facilitate radio frequency (RF) cable connections. Although the TRXs of one synchronous directional cell can be located in two cabinets or cabinet groups, it is not a recommended configuration.
