Cisco Cisco ROSA SI-SERVER Hoja De Datos
Description
The SAII/SAIII transponder is a special purpose status monitoring
transponder designed to interface with Scientific-Atlanta’s System
Amplifier II & III Distribution Amplifier Station. It is controlled by
Scientific-Atlanta’s ROSA
transponder designed to interface with Scientific-Atlanta’s System
Amplifier II & III Distribution Amplifier Station. It is controlled by
Scientific-Atlanta’s ROSA
Element Manager (EM) and Transmission
Network Control System (TNCS) element management systems.
The transponder monitors the operational parameters of the amplifier
and allows remote control of certain amplifier functions.
Communications to and from the transponders are accomplished via the
built-in forward RF data carrier receiver and reverse RF data carrier
transmitter.
The transponder communicates with the ROSA EM and TNCS element
management systems via the Phoenix

Communications to and from the transponders are accomplished via the

The transponder communicates with the ROSA EM and TNCS element
management systems via the Phoenix
RF Modem. The cutting-edge
RF technology used in the Phoenix modem allows operation in networks that suffer from a high level of ingress
noise in the return path.
The transponder monitors a wide range of operational parameters, including:
noise in the return path.
The transponder monitors a wide range of operational parameters, including:
•
Station
temperature
•
AC and DC power supply voltages
•
AGC voltage level detect
•
Housing
opened/closed
If the status of any monitored parameter is outside of established thresholds an alarm can be activated by the
centrally located element management console. All alarm thresholds are remotely adjustable from the console.
The transponder also enables remote control of the reverse “On/-6 dB/Off” RF switches (for remote isolation of
ingress) and of the power supply.
The transponder has a frequency agile FSK data modem, downloadable program storage, and supports current
Scientific-Atlanta (S-A) and AM Communications (AM) protocols. Frequency agility allows the transponder to be
remotely tuned to a new operating channel in the event that communication is impaired by noise or ingress in the
return spectrum. Dual protocol support permits automatic switchover on command from either protocol.
The transponder utilizes internal non-volatile memory for storage of the unit address, calibration data, and other
important operational parameters. Two front panel LEDs are present to indicate the unit is functioning properly,
and the unit is actively being polled. Programming is accomplished by connecting the Model 6585 Handheld
Programmer (1 required) to the RJ-45 style modular Craft connector, thereby allowing the user to configure,
control, and monitor this transponder. The unit is packaged in a formed sheet-metal housing that plugs directly
into the status monitor socket in the amplifier housing.
