INSTALLATION AND OPERATION MANUAL
CNFE1EOC-M
FAST ETHERNET OVER VDSL2 (EoVDSL)
The ComNet™CNFE1EOC-M is an environmentally hardened modem that
supports Ethernet over twisted pair or coaxial cable. The devices use VDSL
(EoVDSL) technology to support data rates up to 90 Mbs. Ethernet data may be
transmitted over a telephone-grade twisted copper pair, legacy serial cabling
or standard 75Ωcoaxial cable circuits. These modems allow for upgrading of
a legacy twisted copper or coaxial cable plant for use with Ethernet rather than
installing new network cabling.
The fastest usable data rate is automatically selected, depending upon the
transmission distance and cable quality. The CNFE1EOC-M may be deployed in
most out-of-plant installations, such as those found in intelligent transportation
systems and factory automation/control applications. LED status indicators are
provided for rapidly ascertaining the operating status of the modem and the
link.
See Figures 1 – 5 for complete installation details.
The CNFE1EOC-M small size unit operates as standalone module only. See
Page 5 for mounting instructions.
