Ethernet to 4/8E1 Inverse Multiplexer

CT-IMUX4/8A-100

Bundles up to 4E1/8E1 lines for cost-effective connection of 10/100Base-TX or 100Base- FX LANs over multiple E1 transports.
Transmits up to a 9.92Mbps/15.87Mbps Ethernet bridge channel (GFP-F encapsulated) over 4E1/8E1 links.
Allows bridges to operate at faster rates and provides high speed access to SDH/SONET backbones where the only access services available are E1 lines.
Features diagnostic capabilities for performing remote loopback. Operator at either end of the line may test both the iMux4A/iMUX8A and the line in the digital loopback mode.

Overview

The iMux4A/iMux8A is an E1 inverse multiplexer capable of bundling up to 4E1/8E1 lines for the cost-effective connection of 10/100Base- TX or 100Base- FX LANs over multiple E1 circuits. The iMux4A/iMUX8A inverse multiplexer transmits up to a 9.92Mbps/15.87Mbps of Ethernet traffic over a bridge channel (GFP-F encapsulated) on 4E1/8E1 links. The iMux4A/iMUX8A bridges the gap between E1 and E3, allowing bridgesto operate at faster rates. It also provides high speed access to SDH/SONET backbones where the only access services available are E1 lines.The iMux4A/iMux8A supports an E1 attenuation of up to 43dB on twisted pair or coax cable. This provides an approximate operating range up to 2km (using 22AWG).

The iMux4A/iMUX8A fully meets E1 specifications including ITU-T G.703 and G.823. The iMux4A/iMux8A features diagnostic capabilities for performing remote loopbacks. The operator at either end of the line may test both the iMux4A/iMUX8A 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.
