“User” types “www.iDirect.net” and presses the enter key. The life of this request begins.
User types “www.google.com” and presses the enter key. The life of this request begins:
The response from www.google.com in the form of digital data leaves the IDIRECT Satellite Router ethernet port via a Cat-5 cable connected to the computer.
The digital data leaves the computer ethernet port via a Cat-5 cable connected to the IDIRECT Satellite router.
The Remote unit will take the digital data from the LAN interface and “modulate” the data onto an analog carrier @ an L-Band frequency. The remote unit will then transmit the carrier to the BUC via the Tx out connector over the Transmit IFL (Interfacility Link cable) The remote unit can also provide +24 VDC to power the BUC as well as provide a 10Mhz reference signal to the BUC over the IFL.
Transmit Bursting TDMA data @ L-Band Frequency
The BUC or Block Upconverter will take the L-Band frequency from the remote unit, Frequency convert or Upconvert it to an RF frequency (C/X/Ka/Ku-Band), amplify the signal and then transmit the signal to the satellite. The 10 Mhz reference from the remote unit is used to generate a stable and accurate Upstream carrier from the BUC.
Receive Downstream DVB-S2 or SCPC carrier at RF Frequency C/X/Ka/Ku Band
The satellite transponder will FREQUENCY CONVERT or “translate” the Upstream RF Transmit frequency from the remote to an RF Receive frequency and send the signal towards the Teleport Hub. The conversion or Translation frequency depends upon the Local Oscillator frequency OR “LO” of the satellite transponder
Receive Bursting TDMA data at Receive RF Frequency C/X/Ka/Ku Band
(RFT) Radio Frequency Terminal
Teleport Hub Antenna

LNA or Low Noise Amplifier Receives the RF Receive Frequency, amplifies it and sends it to the Hub Downconverter
Hub Downconverter
Takes the RF signal (C/X/Ka/Ku-Band) from the LNA (Low Noise Amplifier) and will frequency convert or “downconvert” it to an IF frequency. (L-Band) The signal is then sent to the Hub Chassis via high quality low loss IFL cable.
Evolution Hub Line cards require 2 LAN connections. On the Hub Line Card, the “10/100” port is connected to the “A” row of RJ45 ports on the front of the chassis. The “LAN A” port is connected to “B” row of RJ45 ports on the front of the chassis. The rear chassis ports are then connected accordingly to the Tunnel Switch.
Demodulated and then decoded data packets are received from the Hub Line card and are then sent to the Tunnel Switch.
then arrive at the Protocol Processor on the Tunnel interface.
The Data packets exit the protocol processor on the upstream interface, are then sent to the Upstream switch...
then the Upstream Router...
And out to the Customer Network.
From the Upstream switch the packets are then sent to the
Upstream interface of the Protocol Processor.
The packets leave the Protocol Processor on the Tunnel interface, enter the Tunnel Switch and then are sent to the TX Hub Line card for transmission.
Hub Transmit DVB-S2 carrier@L-Band Frequency
Hub Transmit SCPC/TDM @ L-Band Frequency
Hub Transmit SCPC/TDM @ L-Band Frequency
Hub Transmit DVB-S2 carrier@L-Band Frequency
Hub Upconverter
Takes the IF signal (L-Band) from the Hub Line Card via a high quality low loss IFL cable and Frequency converts or “Upconverts” it an RF frequency. (C/X/Ka/Ku-Band) The signal is then sent to the HPA (High Power Amplifier)
HPA or High Power Amplifier
The signal is amplified and then transmitted to the satellite via the hub antenna.
The satellite transponder will Frequency convert or “translate” the Downstream RF Transmit frequency to an RF Receive frequency and send the signal towards the remote. The Translation frequency depends upon the “LO” or Local Oscillator frequency of the satellite transponder
Hub Transmit Downstream DVB-S2 or SCPC/TDM carrier at RF Frequency C/X/Ka/Ku Band
Upstream Transmit Bursting TDMA data at RF Frequency C/X/Ka/Ku Band
The LNB or Low Noise Block Converter will Receive the RF frequency (C/X/Ka/Ku-band) signal from the satellite and Frequency convert or “downconvert” the signal to an L-Band frequency, amplify the signal and send it to the remote unit via the Receive IFL cable.
Receive DVB-S2 or SCPC @ L-Band Frequency
The remote unit will take the L-Band frequency carrier from the LNB and “demodulate” the carrier, sending the resulting digital data stream to the LAN port switch. The remote unit also provides +18 VDC to power the LNB. It is also capable of providing a 10 Mhz reference signal to LNB if required.
“Tunnel Data”/ proprietary HDLC data
Data packets from the Customer Network enter the Upstream Router, are processed and then sent to the Upstream Switch.
