PRELIMINARY
Objective
The objective of this procedure is to install span line cabling between
multiple BTSs equipped with Primary Surge Suppressor in an open daisy
chain configuration.
Background
This feature allows BTSs to be linked together in an open daisy chain
loop using a single T1/JT1/E1 span. This will reduce the number of
spans necessary to support a JCDMA system and minimize unused
channels.
Each BTS may contain up to four units. A maximum of 12 BTSs may
be combined in a single daisy chain.
Cable Description
The following cables are necessary to do this procedure.
