6.9 LINK THE HOST AND REMOTE DARTS.
“Linking” establishes an association in software between a particular Host DART and
a particular Remote DART, enabling the two DARTs to act as an operational unit in
providing one RF band. There are four pre-requisites to this procedure:
•• The Host DART and Remote DART must be connected through the optical fiber
and be communicating with each other.
•• The Host DART card must be configured as described in “Configure the Host
DARTs” on page 152.
•• The Host and Remote DARTs must be of the same type (such as, Cellular or PCS).
•• There must be a sufficient number of fiber timeslots available in order to
accommodate the requested passband (for example, PCS A band requires 3
timeslots).
In the Remote DART configuration page, all Host DARTs are listed that have the same
band as the Remote DART. A link is established by selecting a Host DART to be paired
with the Remote DART.
6.9.1 Use of Multi Fibers
The EMS provides the ability to install “multi fibers” between a Host and Remote. This
means that, in addition to the minimum two fibers (RX and TX) in the Host to Remote
connection, one or more additional fiber pairs are installed. This is done to increase
the bandwidth between the Host and Remote. Each fiber pair can handle
approximately 75 Mbps of RF bandwidth.
Each fiber is capable of supporting 12 TDM timeslots:
•• Classic DARTs or Single SuperDARTs support up to 35 MHz of RF
– Cellular
–SMR800
–SMR900
– PCS Narrowband
–AWS Narrowband
–EGSM900
•• Dual SuperDARTs support up to 75 MHz of RF
– GSM1800
–UMTS
–AWS Fullband
If you are setting up a multi- host system, go to “(Optional) Configuring Multi-Host
Systems for Manual Mode” on page 168.
