Modular Cabinet – CLU/SLU to Base Station Cabling
21.1 Introduction
This chapter describes all the cabling between the CLU or SLU and the Base Station. Refer to
Chapter 19 on how to supply Base Station power for CLUs or SLUs.
The Modular Cabinet is provided with a ground strip to connect the CLU or SLU cables to ground
(see Fig. 21–1). These ground connections are necessary for EMI suppression reasons.
Two cables sets are used to interconnect the CLU/SLU to the MDF. Cable set NTM/TSRNB 101
29 is 16 ft. long and is terminated in a 25 pair amphenol. Cable set NTM/TSRNB 101 46 is two 82
ft. 12 pair cables unterminated.
Note:
The orientation of the shielding clamps shall be according to Fig. 21–1. If the clamp is positioned at
the wrong side, remove the clamp and fit it such that it is positioned correctly.
