Tahoe 681/682/684 G.SHDSL+ Modems
Tahoe 681/682/684 - G.SHDSL+ Modems with FastEthernet interface
Tahoe 681 and Tahoe 682 modems take advantage of the latest G.shdsl technology providing unprecedented possibilities for copper leased lines. They achieve throughputs of nearly 11.4 Mbps (symmetrical) on the distance of a few kilometres - faster and further than any other modem technology. Developed to combine performance, quality, and scalability, the Tahoe range of next generation DSL modems take advantage of the latest G.SHDSL technology to help address customers’ needs for greater bandwidth while using existing copper infrastructure. The Tahoe 681 uses a single pair of copper cabling achieving data rates up to 5.7Mbps. The Tahoe 682 uses two pairs of copper cabling with speeds of up to 11.4Mbps. The Tahoe 684 uses four pairs of copper cabling achieving speeds up to 22.8Mbps. The modem has a built-in TCP/IP router and an Ethernet 10/100Base-T interface allowing connection directly to a LAN. The Tahoe is manageable using telnet, SNMP, serial console or built-in LCD and keyboard. Traffic statistics are available through the embedded HTTP server while Modem status messages can be sent to a central server using the syslog protocol. Further advanced features include automatic traffic balancing between DSL lines, the ability to configure individual line rates on each transmission line to cater for differences between line pair quality. The modems will also continue to operate should pairs fail, a feature that sets this product apart from its peers.

Tahoe 4681 - Four-port G.shdsl.bis Modem Card
Tahoe 4681 - Four-port G.shdsl.bis Modem Card
The Tahoe 4681 is a 4-port G.SHDSL.bis card providing a total capacity of 32 G.SHDSL.bis lines in a single Tahoe DSLAM. Each line may work separately or they may be bundled within the card to support 1, 2 and 4 pair operation. Each modem port achieves a maximum throughput of 5.7 Mbps. The pairs can be bundled using up to 4 pairs giving speeds reaching 22.8 Mbps. With the Tahoe 4681 card it is possible to connect 4 Tahoe 681 modems, 2 Tahoe 682Tahoe 684 modems or 1 on the other end of the pairs. The traffic on these lines may be mixed together in bridge mode or separated using VLANs. As well as standard G.shdsl modulations they support TCPAM-32 coding - much more efficient than the standard TCPAM-16, giving higher throughputs and higher reach.

Ethernet First Mile Services - EFM
EFM-10/20/40 LAN Extender
EFM-X0 is an Ethernet Network Extender designed to provide bonded high-speed Ethernet First Mile services over SHDSL on existing copper infrastructure. It is a bridge mode modem that delivers Ethernet services with symmetrical bandwidth at rates up to 22.8 Mbps (4 Pairs, Standard mode with TC-PAM 32) and 45.3 Mbps (4Pairs, Enhanced mode with TC-PAM 64). Implemented based on IEEE 802.3ah EFM standards for advanced performance and management features, EFM-X0 ensures high reliability, low expense and maximum throughput. The introduction of EFM copper bonding technology allows delivery of higher bandwidth to longer distances over multiple copper pairs, enabling a good alternative in place where fibre is not economical to deploy. This Ethernet-pure solution provides a seamless integration into today and tomorrows networks. EFM-X0 extends the reach of Ethernet services to the sites by using bonded copper pairs. Up to 4 pairs can be bonded together for aggregated bandwidth over 45Mbps (Enhanced mode with TC-PAM 64 line coding technology). Designed with standard-based EFM technology (2BASE-TL), deployment of Ethernet services with EFM-X0 is quick and simple on the existing copper plant. It operates mainly in Point-to-Point connection between remote office and enterprise headquarters, providing symmetrical high-speed connectivity that is ideal for large and small-to-medium enterprises to deliver business-class Ethernet service.

VDSL Extender
VDSL Extender
The Fast Ethernet VDSL Extender offers transmission of Fast Ethernet across conventional 2-wired lines (telephone or ISTY cable) at distances of up to 1900 m. With transmission speeds of up to 50 Mbps, this extender provides high network performance and can achieve a range of up to 300 m. The bandwidth that can be achieved is reduced correspondingly in the case of greater distances of up to 1900 m. The use of devices is in pairs according to the master/slave principle, in which case configuration is performed using a DIP switch. The network connection takes place via an RJ-45 jack with 10/100Base-TX. The 2-wire line can optionally be connected via an RJ-11 jack or a clamp terminal. The maximum transmission speed is automatically negotiated in 10 speed levels according to distance and transmission quality and signalled to the user via LED displays. In an extended version, the VDSL2 Extender, the maximum transmission capacity can be increased up to 88 Mbps (at 300 m). The maximum distance possible is 2000 m with a data rate of 9 Mbps. The device is designed for an operating temperature range of -40 to +75 °C. Here the connection to the 2-wire cable is done via a RJ-45 port.
