Ethernet E1/G.703 Bridge

CT-FRM220A-Eoe1/G(S)

Ethernet over E1/G.703 bridge for standalone or rack mounted use.

Connects one Fast Ethernet over E1 links (2.048Mbps)
Supports an E1 attenuation of up to 43 dB on twisted pair or coax cable, which provides an approximate operating range up to 2km (using 22AWG).
Supports auto-negotiation and auto MDI/MDIX
Standalone RS232 console management via CH01M
Web/SNMP management via FRM220 20 slot chassis

Overview

The FRM220A-EoE1 is a single E1 Ethernet bridge card capable of carrying 10/100BaseTX or 100Base-FX LANs over single E1 transports. The FRM220A-EoE1 transmits up to a 1.8Mbps Ethernet bridge channel (HDLC encapsulated) over 1 E1 link. The FRM220A-EoE1 supports an E1 attenuation of up to 43 dB on twisted pair or coax cable. This provides an approximate operating range up to 2km (using 22AWG). The FRM220A-EoE1 fully meets E1 specifications including ITU-T G.703 and G.823. The FRM220A- EoE1 features diagnostic capabilities for performing remote loopback. The operator at either end of the line may test both the FRM220A- EoE1 and the line in the digital loopback mode. The Ethernet copper interface supports auto-negotiation and auto MDI/MDIX, allowing plug-and-play Ethernet connection without any additional configuration.

Management Features

The FRM220-Eoe1/G has an on-board 2 pole DIP Switch which can be used to configure the device timing source (recovery or internal) and the framing mode. When placed in a stand-alone chassis with DB9 console port (see below), these devices support a text based serial terminal with an easy to use menu system for configuration. When placed in a managed chassis, the card is configured and monitored through the chassis NMC (network management controller) via console, Telnet, Web HTTP or SNMP
