5.2
CONTROL AND COMMUNICATION
The DTR-0200-SA-SIRIUS terrestrial repeater can operate in either of two condi-
tions; remote control condition or local control condition
5.2.1
Remote Control Condition
In the remote control condition the Network Management Center (NMC) operator can
control and monitor the repeater from his/her position via telephone line dial-up, and
by use of WEB and SNMP interfaces to perform network management.
5.2.2
Local Control Condition
In the local control condition the technician can control and monitor the repeater from
the terrestrial site location. The technician uses a laptop PC for local control and
maintenance procedures. The PC communicates with the repeater via Ethernet and
Graphical User Interface (using Internet Explorer) or Command Line Interface (CLI)
protocol using the RS-232 Comm Port.
5.2.3
Control and Communication Interfaces
There are three interface ports provided for control and communication. They are:
RS-232 Serial Port (DB9) –used for local control, status information, initial setup,
and troubleshooting. Access is local via laptop PC and the supported protocol is
Command Line Interface (CLI).
V90 Modem Port (RJ11) – used for remote control and status information. Access
is from the NMC via dial-up modem and telephone and the supported protocols
are SNMP
, WEB Interface, and Telnet.
Ethernet Port (RJ45) – used for local control and LAN access. Access is local and
the supported protocols are SNMP, WEB Interface, and Telnet.
5.2.4
Remote/Local Control Switching
The normal condition for repeater operation is the remote control condition. For a tech-
nician to perform testing and maintenance from the local terrestrial site, the repeater
must be switc
hed to the local control condition. Switching is activated by the use of an
SPU front panel push-button switch. LEDs on either side of the switch identify the
repeater control condition as being in local or remote. Placing the repeater in the local
