ARCXTEND 5.8 GHZ USER MANUAL – R1.0, ISSUE 1

The gain of the CPE is fixed in both the upstream and downstream direction. The transmit

power of the CPE directed towards the Hub will vary based on the input RF signal received from

the cable modem. The CPE can accept an input RF signal between 20 and +58 dBmV from a

cable modem. The downstream output power out of the CPE directed towards the cable modem

will vary based on the distance between the Hub and the CPE. It is typically in the range of +10

to +30 dBmV. Arcwave provides specially designed low pass attenuators to reduce the

downstream power level to within the – 15 dBmV and +15 dBmV operating range of a cable

modem. Note that for 256 QAM the downstream power level into the cable modem must be at

least -6 dBmV.

Element Management

Each Hub contains Arcwave’s ARCSmart intelligent network management which combines an

embedded DOCSIS 2.0 compliant cable modem, SNMP-compliant Arcwave Enterprise MIB

(management information base) and a processing engine with upgradeable software to support

low cost configuration monitoring, and troubleshooting of a Hub.

Management of the CPE can be most cost effectively achieved using the capabilities built into

the subscriber cable modem. The CPE has no settable parameters so management is not

required.
