2. Orion Telecom Networks Inc. - 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. Orion Telecom Networks Inc. - 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 Features and Highlights

4. Orion Telecom Networks Inc. - 2010Slide 4 Ethernet over E1(FE1) Features and Highlights  Imbedded, dynamic Ethernet MAC address list (1024 addresses), and filter function for local data frames Can support multiple LANs of different network addresses  Optional powers 220V AC and -48V DC  Supported fractional E1. E1 Bandwidth can be adjusted from 64 Kbps to 2048 Kbps and selected in N*64Kbps format  Provides 120 Ohms – RJ45 and 75 Ohms - BNC E1 interface in the same box (user selectable)  Configurable Ethernet port speed (10 /100) and mode (Half / Full Duplex)  Ethernet port mode status (LEDs)  Plug and Play  Very compact and low power consumption.

5. Orion Telecom Networks Inc. - 2010Slide 5 Ethernet over E1(FE1) Applications  This equipment may be used for the following purposes: Bridging Ethernet LANs over existing TDM (E1) telecom network Extending Ethernet Networks utilizing TDM (E1) landline based telecom infrastructure Using telecom network of E1s / PDH / SDH Microwave etc. Carrying E1s to transport Ethernet data  In all these cases the equipment be always installed and used in pairs, with one terminal being installed at either end (each side) of the network.
