Overview

The FRM220A-iMux is an E1 inverse multiplexer capable of bundling 4, 8 or 16 E1 lines for the cost-effective connection of 10/100Base-TX LANs over multiple E1 transports. The FRM220A-iMux bridges the gap between E1 and E3, allowing bridges to operate at faster rates. It also provides high speed access to SDH/SONET backbones where the only access services available are E1 lines. The FRM220A-iMux supports 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-iMux features diagnostic capabilities for performing remote loopback. The operator at either end of the line may test both FRM220A-iMux NTU 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

Management functions are accessed via RS232 when the iMux is used in a CH01M or CH02M (see "Mounting Options" below). Alternatively, web or SNMP may be used when the iMux is used in a larger chassis with an FRM220-NMC card.
