2. Copyright: Valiant Communications Limited - 2010Slide 2 Ethernet over E1 (FE1) Product Overview  Ethernet over E1 Converter provides the user a facility to transport Ethernet (multiple LANs) over an E1 link.  Very Compact and Low cost.  Converts and transports Ethernet sites over an E1 link.  The device can effectively utilize the redundant bandwidth of telecom operators' existing TDM network to transport Ethernet data with low investment.  Optional powers 220V AC and -48V DC.  Provides 120 Ohms – RJ45 and 75 Ohms - BNC E1 interface in the same box (user selectable).  Plug and Play.

3. Copyright: Valiant Communications Limited - 2010Slide 3 Ethernet over E1 (FE1)  The maximum transmission rate of Ethernet data over E1 links is 2.048 Mbit/s.  Supporting 1600 frames, accordance with Interior Switching Link (ISL) Protocol.  Supports unframed, framed and multi framed E1 transmission mode.  Supporting local E1 port loop-back.  The Ethernet Port is self-adaptive to crossover or shoot-through (Straight / Parallel) cable to avoid the trouble of re-wiring.  Ethernet negotiation function. Supports 10M/100M and working modes of both full-duplex and semi-duplex.  Transparently transmits ultra-long frames stipulated in IEEE 802.1Q, and supports Ethernet switches with VLAN function.  Transport the DATA transparently (No configuration required).  Visual alarms (LEDs) on front panel.
