22.1 Introduction
This chapter describes the installation of the cabling between the DTU(s) and MS/PBX by means
of twisted pair cables. The description is applicable for DTU-E1CAS, REX-BRD0002 or
2/ROFNB 157 13/1, DTU-E1 CCS REX-BRD0003 or 2/ROFNB 157 13/6 and DTU-T1, REX-
BRD0021 or 2/ROFNB 157 13/3 and 2/ROFNB 157 13/2 .
The Modular Cabinet is provided with a ground strip to connect the cables from the DTUs and the
CLUs/SLUs to ground. These ground connections are necessary for EMI suppression.
Note:
The orientation of the shielding clamps shall be according to Figure 22–1. If the clamp is
positioned at the wrong side, remove the clamp and fit it such that it is positioned correctly.
