  1. Valiant Communications Limited Telecom Transmission Solutions 4 Ethernet over E1 (4xFE1) Product Presentation Updated: 29 April, 2010

  2. Product Overview • 4 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 upto 4 x Ethernet links over an E1 in a shared mode, or a discrete mode, depending on the user's preference and selection • In shared mode: All 4 Ethernet channels are transported over the same shared E1 link and are allowed full access to each other's path • The user may select this mode if the user desires that all of the 4 x Ethernet links that are being transported over the same E1 to optimally share its bandwidth resources and where discretion is essential • In discrete mode: All 4 Ethernet channels are transported over the same E1 link, but without allowing intrusion or access to each other's path.

  3. Product Overview • The user may select the discrete* mode when the user desires to transport all 4 Ethernet channels over the same E1 line discretely and without allowing access to each other • 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.

  4. Features and Highlights • The maximum transmission rate of 4 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 • The Ethernet Port is self-adaptive to crossover (Straight / Parallel) cable to avoid the trouble of re-wiring • Supports up to FOUR Ethernet Ports. Supports port masking. • Supports 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.

  5. 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 • Transports DATA transparently (No configuration required) • Visual alarms (LEDs) on front panel • 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) • Supports speed limit function for different Ethernet ports.

  6. Features and Highlights • VLAN (port based) mode supported to isolate the Ethernet Data from local Ethernet ports • Ethernet port mode status (LEDs) • Plug and Play • Low power consumption.

  7. 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.
