5.3.5 Receive (Upstream) Signal Path
The upstream signal IF signal from the Hub Transceiver is connected through the lightning
protector and through the 12 dB tap to the upstream port of the W-CMTS. The Table in the
Antenna and Frequency Planning section of this manual details the frequencies that are
available. Unlike the downstream, where the frequency is established by the external or internal
upconverter, the upstream IF frequency is established as a configuration parameter of the W-
CMTS which commands the wireless cable (WCM) modem to transmit on a particular upstream
IF frequency.
5.4 Hub Interfaces
This Section lists the interfaces encountered at the base station site.
5.4.1 Hub Transceiver
Transmit and receive signal interfaces:
• 75 ohm type F female connectors
• Premium quad-shielded RG-6 coax cable recommended (e.g. Belden 1189A)
• Upstream signal frequency 6.4 through 32 MHz, nominal signal level -4 dBmV

.
• Maximum cable loss between Hub and W-CMTS: 15 dB at 30 MHz.
• Downstream signal frequency 477 through 577 MHz, nominal signal level 50 dBmV.
• Maximum cable loss between upconverter/CMTS and Hub: 15 dB at 500 MHz.
Power interface:
• Switchcraft type EN3 6 pin male connector on both upstream and downstream radio
enclosures (two per Hub Transceiver).
• Nominal 8.0 – 8.5 VDC at 920 mA +/- 50 mA, combined upstream and downstream.
Antenna interface:
• None. These are internal to the Hub Transceiver.
5.4.2 BSR1000W Wireless CMTS
Mirrors the above Transceiver, assuming no taps and only minor coaxial cable losses.
5.4.3 V3000W Wireless CMTS
• 75 ohm type F female connectors
• Upstream input signal frequency 6.4 through 32 MHz, nominal signal level -4 dBmV.
• Downstream output signal frequency: 44 MHz, nominal signal level 20 dBmV (input to
Upconverter)
• Network connection RJ45 female connector: 100baseT Ethernet LAN.

For 75-Ohm systems, 1 mW = 0 dBm = 48.8 dBmV.
