Ethernet bridge DSL modems

AccessDSL is a wide range of DSL modems targeted to meet both typical carrier applications and access network needs.

Main Features

Faster and Easier Internet Access and LAN-to-LAN Interconnection without ATM DSLAM infrastructure

AccessDSL EtherLink is designed for business-oriented high-speed Internet access, AccessDSL EtherLink series is applicable as a fully scalable CO IP-DSLAM product, where investments are synchronized with demand, Being able to extend the capacity of the CO shelf with one or two DSL ports Incr ements, the provider still benefits fr om the very economical link price, using EtherLink stand-alones for CPE side, the Universal CO shelf accommodates also many other AccessDSL/AccessGain products like E1/N64 DSL modems, VolP gateways, fiber-optic modems, cross-connect, voice and data TDM mux.

AccessDSL EtherLink series offers symmetrical service at the speed from 192kbps to 4.6Mbps for the distances up to 7km over one or two copper pairs. S ymmetrical transmission (unlike ADSL) implies no application limitations. High-speed bi-dir ectional transmission is very suitable for business DSL subscriber s who prefer to run WWW and mall server’s at-site, in the local LAN. Another key feature of AccessDSL EtherLink VLAN functionality - helps to build cor porate virtual networks connecting branch offices and home-employed staff.

Protected (1+1) operation over two copper pairs with a maximum speed of 4.6Mbps is an advanced option of AccessDSL EtherLink to support VIP DSL services and trunk communications between ISP' switches. Independent line speed adjustment for each pair allows optimal speed-distance ratio.

Unlike many other Ethernet DSL modems, AccessDSL EtherLink uses Ethernet over DSL technology. It secures 95% of the DSL channel capacity for customer traffic, thus, providing up to 530kbyte/s file transfer rate, that is, 10-15% faster comparing to Ethernet over ATM based DSLAM and CPE devices.

Being focused on ISP applications where connection cost, manageability and security are the major factors, AccessDSL EtherLink works as a transparent bridge, where all CPE units are fully controllable and configurable from the CO side locally or via centralized management system. Taking into account the increasing thread of Internet based intrusions, firewall and router/switch functions, which are the keys to the subscribers' corporate security, are left to external devices to be completely independent from the DSL service provider.

As on operator class DSL devices AccessDSL EtherLink offers extended operation statistics, including such parameters as number of packets transmitted in both directions, total service an out-of-service time, number of lost connections, total working time.
