Ethernet over E1 (FE1) Product Presentation

1. Valiant Communications Limited Telecom Transmission Solutions Ethernet over E1 (FE1) Product Presentation Updated: 29 April, 2010

2. Product Overview • Ethernet over E1 (FE1) Converter provides the user a facility to transport Ethernet (multiple LANs) over an E1 link. • Compact and Low cost. • Converts and transports Ethernet 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. • Power Input options: 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. Features and Highlights • The maximum transmission rate of Ethernet data over E1 links is 2.048 Mbit/s. • Supports 1600 frames, accordance with Interior Switching Link (ISL) Protocol. • Supports unframed, framed and multi-framed E1 transmission mode. • Supporting local E1 port loop-back. • Ethernet Port is self-adaptive to crossover (Straight / Parallel) cables 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.

4. 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. • Power Input options: 220V AC and -48V DC. • Supports 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. • Low power consumption.

5. 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 will be always installed and used in pairs, with one terminal being installed at either end (each side) of the network.
