INSTALLATION AND OPERATION MANUAL

CNFE1CL1MC(-M)

FAST ETHERNET OVER VDSL (EoVDSL)

The ComNet

™

CNFECL1MC(-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 75Ω coaxial 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 CNFECL1MC(-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 – 8 for complete installation details.

The CNFE1CL1MC standard size unit may be directly plugged into the ComNet

Rack (Part C1) or operated as a standalone module. The CNFE1CL1MC-M

small size unit operates as standalone module only. See Page 5 for mounting

instructions.

MECHANICAL INSTALLATION INSTRUCTIONS Installation Considerations This fiber-optic link is supplied as a Standalone/Rack module. Units should be installed in dry locations protected from extremes of temperature and humidity. CAUTION: Take care not to press on any of the LEDs. 2. Tighten the two thumb screws on the card until the front panel of the card is seated against the front of the rack.
