 |
| The ERM04 is a rack solution for inverse E1 multiplexer that will multi-link up to four-E1-lines and offers |
| simple,cost-effective connection between E1 service and 10/100BaseT LANs. Each line card of ERM04 |
| inverse multiplexer transmits a 7.68Mbps Ethernet bridge channel over 4 E1 links. |
| The ERM04 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 line card 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 ERM04 fully meets E1 specifications including ITU-T G.703 and G.823. The ERM04 features diagnostic |
| capabilities for performing remote loopback. The operator at either end of theline may test both the ERM04 |
| and the line in the digital loopback mode .The Ethernet interface supports auto-negotiation,allowing plug |
| -and-play Ethernet connection without any additional configuration. |
