The FRM220A-iMux16 is an E1 inverse multiplexer capable of

bundling up to 16 E1 lines for cost-effective connection of

10/100BaseTX or 100Base-FX LANs over multiple E1 transports.

The FRM220A-iMux16 inverse multiplexer transmits up to a

31.74Mbps Ethernet bridge channel (GFP-F encapsulated) over 16

E1 links. The FRM220A-iMux16 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-iMux16 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-iMux16 fully meets E1 specifications including ITU-T

G.703 and G.823. The FRM220A-iMux16 features diagnostic

capabilities for performing remote loopback. The operator at either

end of the line may test both the FRM220A-iMux16 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.
