over an ac input between 50 Vac and 110 Vac with a line frequency from 50 Hz through 60 Hz.

A 20-ampere fuse is furnished in the power supply module and provides over current protection

for ac power applied to the input. SCTE compliant surge protection is provided in the power

supply.

DC Powering

The Hub can also be powered through the weather-protected Ethernet port using Power-over-

Ethernet. The power level at the Ethernet Port should be between 18 and 26 Vdc.

RF Signal Power Level and Quality

The Hub requires a downstream path RF power level at the input RF port of between 0 dBmV

and +30 dBmV. The modulation error ratio (MER) going at the input RF port should be within

the budgeted range for the wireless link. In general a minimum MER of 35 dB is required for 256

QAM and 31 dB is required for 64 QAM downstream path modulations.

CPE Electrical Interface

The CPE is powered over and connects to the cable modem, using standard coaxial cable.

AC Powering and Surge Protection

The CPE is powered through the RF output port. The CPE is powered with 18 Vdc. Arcwave

provides a 120 VAC CPE power pack and a power inserter approved for use with the CPE. The

CPE must typically be located within 300 feet of the power pack to insure adequate powering of

the CPE.

Lightning Protection

The CPE must be mounted at least 2 feet below the highest point at the site to minimize the

likelihood of lightning strikes. The location should be properly grounded for lightning protection

to all applicable national (National Electric Code, sections 820-33 and 820-40) and local codes.

To protect the customer equipment from surges on the coaxial cable that is connecting the CPE

to the cable modem, the installation of an SCTE compliant surge protector is required.
