the top of the DBS sub-rack, if no distribution frames (cf. § 3.5.3.1 Direct connections to the con-

nectors of the top panel of the DBS chassis.);

– or the optional distribution frames at the top of the DBS sub-rack in the standard rack (coaxial

cables for the 75 ohm links, balanced pair cables for the 120 ohm links cf. § 3.5.3.2 Connections

to 75 ohm coaxial distributors and § 3.5.3.3 Connections to 120 ohm distributors).

Note: the provided equipment is already connected and parts of the installation kit.
