3BK 17422 1071 RJZZA Ed.04 7 / 32

1 Overview

1.1 PresentationClock synchronization between different BTSs is required for typicalapplications, such as:

Synchronous handover

Cell shared by two BTSs.

MASTER SLAVE HW+SW limitation

G2 Standard G2/A9100 3

G2 Mini G2/A9100 2

A9100 Medi / Mini G2 1

A9100 Medi / Mini A9100 3 BTSs in chain

2 BTSs in star

Table 1: Possible BTS Synchronization

This method covers retrofit actions for the boards of G2 BTSs, changing thesynchronization mode from "free running" to "PCM" for the master G2 BTSs,and synchronizing one or several slave BTSs to a master BTS.

G2 Slave BTSs are always in star connection.

G2 BTS equipped with STSE, STSP boards can be master or slave.

G2 BTS equipped with STSR boards can only be slave.

1.1.1 Cases

The following cases apply for the new synchronized BTSs:

Retrofit Action - Preparing the master G2 BTS:

C1: G2 BTS with redundant configuration (2 STSx boards)

C2: G2 BTS non-redundant configuration (1 STSx board).

Master Configuration:

C3: Change of master G2 BTS synchronization mode from "free running"

to "PCM synchronization"

C4: Master A9100 BTS.

Slave Configuration:

C5: Slave G2 BTS(s)

C6: Slave A9100 BTS(s).

1.1.2 Options

None.

1.2 Preparation

1.2.1 Prerequisites

The following prerequisites apply:

All the BTSs on the non-synchronized site are configured as master

All the BTSs on the site, including the new integrated BTSs, are consideredinstalled, commissioned and connected to the BSC

3BK 17422 1071 RJZZA Ed.04 9 / 32

1 Overview

G2 Mini-BTS Indoor and Outdoor and G2 BTS Standard Outdoor must bepre-cabled. This means cabling between the connection box and the

subrack is present (old versions of G2 BTS could be without pre-cabling)

Maximum number of BTSs on site is four

Distance between BTSs (according to the cable length) is maximum 10

meters.

To provide a higher quality of synchronized handover, it is preferableto replace the STSE AAxx or STSE ABxx boards of the Master BTSwith STSE ACxx10 or STSP performing a "Retrofit Action" (see CheckHardware Technical Status and Perform Retrofit Action on Master G2 BTS(C1, C2) (Section 2.3.2)). Make sure that the Hardware Technical Statusof the boards is the same, in accordance with Set STSE / STSP, STSRBoard Switches (Section 2.5.3.1)

1.2.2 Site Specific Information

The following site-specific information is needed:

Master BTS identification and type

Slave BTS(s) identification and type.

1.2.3 External Tasks

None.

Figure 6: G2 Standard Indoor BTS Cabling

Master BTS cabling:

1. Unscrew the waveguide gasket. Unscrew the rack top front plate.

2. Run the cable through the waveguide gasket, then behind the rack topfront plate.

3. Connect the ground on the MBSR back side, using the material and screwsfurnished with the cable.

4. Run the cables on the left side of the frame.

5. At the top of the rack, unscrew the two captives screws (flat bladescrewdriver needed). At the bottom of the rack, undo the two latchbolts-socket cap screws ( 8mm Allen key needed).

6. Pull the frame on the rails out from the outer cladding as far as it will go toretain the maximum of spare cable length.

7. Connect the cables to the X600 connector at the back side (see Figure 5).

8. Check that shielding is in contact with the waveguide gasket and re-secure it.

9. Insert the frame back in the rack doing the reverse operations for steps 6,5, and 1.

Slave BTS cabling:

1. Unscrew the waveguide gasket. Unscrew the rack top front plate.

2. Run the cable through the waveguide gasket, then behind the rack topfront plate.

3. Connect the ground on the MBSR back side, using the material and screwsfurnished with the cable.

Figure 7: G2 Mini Indoor BTS XCLK Port Locations

Two cables have to be installed between the right connection ports of the BTSs:

On the Slave BTSs: synchronization cables coming from the Master BTS

have to be connected to the M/N&R ports

On the Master BTS: synchronization cables going to the Slave BTSs have to

be connected to the S1/N&R (for Slave 1) and S2/N&R (for Slave 2) ports

Port N (normal) is connected to port N (normal) of the second BTS

Port R (redundant) is connected to port R (redundant) of the second BTS.

For Slave BTSs, check that the internal cables are connected between theinside ports of the connection box and CLK IN ports of the STSx boards.

Note: For the Master configuration, the cables exist but they are not connected.

In the specific case of non-redundant G2 BTS, only one synchronization cablebetween Master and Slave is necessary.

G2 BTS Mini and Standard Outdoor

Two cables have to be installed between the connection boxes of the BTSs:

On the Slave BTSs: synchronization cables coming from the Master BTShave to be connected to the CLK N&R ports

On the Master BTS: synchronization cables going to the Slave BTSs have to

be connected to the CLK N&R ports

30 / 32 3BK 17422 1071 RJZZA Ed.04

2 Scenario

Port N of the Master BTS is connected to port N of the Slave BTS

Port R of the Master is connected to port R of the Slave BTS.

To install the synchronization cables:

1. Run and secure the cables in the cable tray between the racks.

2. Introduce the synchronization cable in the BTS compartment through thecable entry tube. Use a heat-shrinkable sleeve to isolate.

3. Secure the cable inside the plinth.

4. Connect a 9-way SubD connector to the synchronization cable.

5. Secure the cables at the top of the connection box.

6. Label the cables.

7. Connect synchronization cables to the CLK ports of the connection box.

8. For the Slave BTS, check that the internal cables are connected between theconnection box and the CLK IN ports of the STSx.

2.5.3 Configure G2 BTS Master/ Slave STSE / STSP and STSR Boards

2.5.3.1 Set STSE / STSP, STSR Board Switches1. Remove the board from the BTS.

2. Set SWITCH 2 (Master or Slave) to:

OFF for a Master BTS (default value for STSE / STSP)

ON for a Slave BTS (default value for STSR).

Note: The position of Switch 2 can be checked at the BTS terminal by followingthe menu path:

Show > HW Configuration > SBL and select CLLK from the list.

3. Set SWITCH 3 (Clock synchronization frequency, used when the BTS isSlave) to:

OFF if Master BTS is a G2

ON in all other cases.

4. Set SWITCH 4 (to change from "PCM synchronization" to "free running",used for a G2 Master BTS equipped with an STSP board) to:

ON if PCM Synchronization

OFF if free running.

Note: The position of Switch 4 can be checked with the BTS terminal by followingthe menu path

Show > HW Configuration > SBL and selecting CLLK from the list.

5. When all switches are correctly set, re-insert the board in the BTS.

2.5.3.2 Hardware Technical Status for STSE, STSP, STSRWithin a BTS, the hardware technical status must be the same for both STSE(or STSP, STSR) boards.

If two BTS are synchronized, the hardware technical status must be compatible:
