Product Presentation
Updated: 29 April, 2010

2. Product Overview
Ethernet over Multi E1 Converter allows the user to connect to Ethernet sites over point to point E1 link / links

One or more than one (up to 16) E1 links can be used to carry the Ethernet data over E1 link as per the application requirement
Flexible Interface options - E1 (120 / 75 Ohms) and Ethernet (Optical / Electrical)
E1 Options - Available in 4E1, 8E1 and 16E1 port versions
Ethernet Options – 4 Electrical or 1 Optical + 3 Electrical
LCAS feature supported to adjust the bandwidth automatically according the availability of E1 links without disturbing the current running services.

3. Product Overview IEEE 802.1Q and 802.1P based QoS features supported
