Menu Split Site 1/2 (3041)
The operation of transmitters with high power levels close to receivers in the same site may
cause interference for some receptions. To avoid this problem, the locations of the transmit-
ter and receiver units can be physically separated (split site).
The Split Site System allows flexible assignment of separated receivers and transmitters to
controllers located at the Control-Site. A list of predefined Split Site Transmitters and Split
Site Receivers can be configured through R&S RNMS3000 or using the MMI.
The Split Site Controller is able to connect to any of the available transmitters and receivers
at the remote Tx and Rx sites. The allocation of the Split Site Transmitter and Receiver can
be done via remote control command or from the MMI of the Split Site Controller. The Split
Site radios (Transmitter or Receiver) allow only one connection at a time to a Split Site Con-
troller. They are monitored by the Split Site Controller through the supervision of the Contin-
uous Built-In Test (CBIT) (see sect. 6.2 Troubleshooting: Radio Built-In Test). All parameters
configured for the Split Site Controller and relevant for the system operation are automatical-
ly sent from the Split Site Controller to the allocated Split Site radios. To allow the Split Site
Controller to have the access right for controlling the Split Site radios, these radios must not
have a Local or Fixed Session (see sect. 3.3 Control and Monitoring of Radio and Control
Unit: Session Types and Access Rights).
If the Split Site Transmitter loses its connection to the Split Site Controller, an ongoing trans-
mission is aborted. For the transmission of data and remote control signals between the Split
Site Controller and the allocated Split Site radios (Transmitter and Receiver), the IP interface
of each radio is used. The audio is encoded with G.711 A-law and sent in RTP packets from
the Split Site Controller to the Split Site Transmitter and from the Split Site Receiver to the
Split Site Controller.
The following devices are supported for playing a role in a Split Site system.

with additional power amplifier stages (R&S VK4150 or R&S VK4190)
All audio accessories and RF interface accessories, e.g., ATU and Transmitter Filter, avail-
able for R&S M3SR Series 4100 Radios are also supported. These devices have to be con-
figured directly at the device they are connected to.
All external half duplex modems compatible to R&S M3SR Series 4100 Radios are support-
ed if they can cope with the Split Site System delay.
