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 servers 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
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
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.
