User Manual

On the master-side station, the WDM i-link modules are to be housed into 2

adjiacent slots, chosen among the 12 available ones in the subrack.

On the slave-side subrack, the WDM i-link modules are to be housed into 4

adjiacent slots: moreover, due to the particular cabling they require, these 4

adjiacent slots should be placed in mid-subrack, so that no more than 4 TFLN

local units stay on each side of the WDM i-link modules (see fig. 5.39).

Note

: If the TILx-HLW modules are to be installed in an already working

Master Unit, switch off the sub-racks before inserting the modules.

Before inserting the boards into the TPRNx4 subracks, make sure to set

proper RS485 addresses. A basic rule of the Britecell installation is that 2

subracks belonging to the same Master Unit should always have different

RS485 addresses (please refer to “TPRN Installation” section): since the

interconnect-link basically provides an extension of the Master Unit bus, any

subrack on the i-link master-side should also have a RS485 address different

from any subrack on the i-link slave side.

Please refer to “TPRNx4 Installation” section for more information on setting

the RS485 address.

Firstly, carefully insert the TMRX-500 and the TDTX-300 boards in 2 adjacent

slots of the Master side subrack. Lock the 4 screws on the corners of each

boards.

Use the provided SMA-m RF jumper in order to connect the RF Out Port of the

TMRX500 module to the RF In Port of the adjacent TDTX300 module. Use the

SMB-f jumper to connect the 10.7MHz ports of the two boards. Fix these RF

jumpers to the RF ports through a proper torque wrench (not included).

Remove the protection cap from the optical ports of the 2 modules on the

master side.

Take the optical jumper, clean the fibre connectors, and use it to connect the

1310 output port of the TDTX 300 and the 1310 input port of the TMRX500
