Overview
The FRM220-DS3/E3 is a fibre modem used in pairs to transparently extend DS3, E3 or STS-1 transmissions over optical fibre. By utilizing pluggable SFP transceivers (155Mbps), these converters may be easily deployed on multimode or single mode fibre, at a distance up to 120km, or over a single core fibre using BiDi (WDM) SFP modules.
The DS3/E3 connections utilize industry standard BNC connections for transmit and receive via coaxial cables. When the FRM220-DS3/E3 card is used standalone in a single slot chassis(see mounting options below), DIP switches may be used for configuration and loopback control. When placed in a single slot chassis with console port, an easy to maneuver user menu is available via terminal to configure, monitor, and run diagnostic loop back functions. The EOC (embedded operations channel) allows in-band management to control the remotely connected modem over a working fibre link. When the FRM220-DS3/E3 card is placed in the FRM220 rack with NMC management, the administrator can configure and view the local and remote converter cards' status, type, version, fibre link status and alarms.
