2.8.2 – Marking IF cables for identification
IF cables must be marked to indicate which X-Pol RBS Tx or X-Pol RBS Rx each cable connects to. It
is recommended that you use bands of electrical tape to identify each cable:
– the tape color (blue, red, green or yellow) indicates the sector,
– the number of colored bands of tape indicates the X-Pol RBS Tx or X-Pol RBS Rx number in the
sector,
– a white band on either side of the colored bands indicates that the IF cable connects to a redun-
dant X-Pol RBS Tx or X-Pol RBS Rx.
Table 21 describes the electrical tape recommended for marking IF cables.
