Nomus Gateway e/ES & /ESL

Ethernet over Bonded G.SHDSL.bis

Nomus Gateway e /ES and /ESL are very cost-effective and flexible Etherent Access Products. They offer connectivity to MPLS/IP networks over ordinary Twisted Pairs using SHDSL.bis. The Gateway e/ES uses two bonded SHDSL.bis pairs to offer speeds of up to 30Mbps. It automatically operates at reduced rates if one of the wire-pairs is damaged or disabled. Similarly, restoral to higher Bandwidth is automatic when the unused pair is enabled. The /ESL is a low cost product offering 13 Mbps on a single Pair. Both products offer a reach of up to 10 KMs for lower speeds. Connectivity at 4 Mbps is supported over TDM networks when used with Nomus G.703 Modems & the Nomus iMux

The Gateway /ES & /ESL are equipped with four FE ports for versatile LAN access. They provide VLAN & QoS capability for differentiated services. Local management is via a Serial Console. In-Band Management via HTTP, Telnet is supported from local or remote location. SNMP is supported in Gateway /ES only. A bank of LEDs provides comprehensive status indication.

Performance and Reliability are the hallmarks of all Nomus products and these products are no exceptions. The Nomus Gateway e/ES & /ESL are designed to meet stringent operating conditions. The Power Supply can be used with AC or DC power & operates over an extended range. The Line interface is equipped with a protection circuit designed to withstand Power Surges as per ITU K.20/K.21 standards.
