XM-4E1-TTX a 4 E1/T1 Inverse mux or converter of 4 E1/T1 to an Ethernet

The XM-4E1-TTX is an interface converter carrying Ethernet 10/100BaseT toward 1 to 4 bonded E1/T1 circuits. This equipment offers automatic E1/T1 channel failure detection and will re-assign the number of E1/T1s available for the transport of the Ethernet traffic.

This inverse multiplexer is deployed for economical high speed leased lines when an ISP needs to deploy 8Mbps Internet access and for the enterprise and military to deploy LAN to LAN over PDH, SDH or Radio networks.

Feature of the XM-4E1:

• 1 to 4 E1 G703, with automatic bounding
• Maximum rate 7280 Mbps
• GFP (Generic Frame Protocol) is used to map the Ethernet packet into the virtually-concatenated E1’s
• Ethernet 10/100BaseT auto detecting function
• Support VLAN packet transparent
• Up to 1916 bytes for optional MAC learning is included.
• Support Ethernet, SNMP, and in band management
