| The ETU04 is an inverse E1 multiplexer that will multi-link up to 4 E1 lines and offers simple,cost-effective |
| connection between E1 service and 10/100BaseT LANs. The ETU04 inverse multiplexer transmits a |
| 7.68Mbps Ethernet bridge channel over 4 E1 links. The ETU04 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 service available is E1 lines. The ETU04 supports 4*2.048Kbps G.703 E1 lines, |
| for a line attenuation of up to 43 dB on twisted pair or coax cable. |
| This provides an approximate operating range up to 2km (using 22AWG). The ETU04 fully meets El |
| specifications including ITU-T G.703 and G.823. The ETU04 features diagnostic capabilities for performing |
| remote loopback. The operator at either end of the line may test both the ETU04 and the linein the digital |
| loopback mode. The Ethernet interface supports auto-negotiation, allowing plug-and-playEthernet |
| connection without any additional configuration. |
