The VX-2000MD IP based DSLAM
concentator is the preferred choice for Telecom and
Internet Service Provider�s with high density network
environments such as local loop, campus, multi-tenant
apartments, multi-tenant commercial, multi-tenant student
dorms, and Hotel/Motels. This access routing concentrator
can accommodates up to 16 line cards with 24 ports each.
With this high bandwidth flexible backplane design, the
system combines a variety of technologies to address
different market requirements.
The VX-2000MD Provides a Gigabit Ethernet routing switch
control card (MCU) with network management for end-to-end
operation, network administration, maintenance, and
provisioning of the MDU access concentration. The gigabit
Ethernet management control card can aggregate traffic from
phone line cards to an external network device. The phone
line ADSL2+ card can be operated either stand-alone or with
the gigabit Ethernet concentration or switching control
board.
Fully Redundant MCU and Power Supply platforms designed for
uptime reliability. A pair of redundant MCU are specially
designed for
the VX-2000MD ADSL2+ IP DSLAM device without service
interruption. The Line Cards utilize individual power
modules which
enables operation directly from a �48VDC power source. The
DC voltage operating range supports worldwide Telco
environments.
Includes a built in Test Access Matrix. The implementation
provides
quick access to any circuit on the chassis for line/loop
diagnostic without
the physical presence of a technician. Includes a built in
voice/data splitter. The added circuit offer ease of
installation, cost savings without an external Splitter rack
and reduces cabinet space requirements.
Share the existing POTS (Plain Old Telephone Service)
wiring to
provide connectivity to subscribers, eliminating the need
for new wiring.
The system provides flexible and variety bandwidth services
depend
on the subscriber demand. This solution brings faster ADSL2+
high-speed networking Internet services to the subscribers
by using
existing phone-line found in the home and business. With
high bandwidth ADSL2+ technology, the voice and data
operates simultaneously over the same pair of copper wire
without interfering with voice service.
This system can be remotely managed and software
upgraded.
This function eliminates the need for field upgrade. All
cards are hot
swappable which minimize service outage times. There are 4
devices
can be fitted into a standard Telco cabinet, up to 8
cabinets per a
DSLAM group and total up to 12288 subscribers per group.
Provides most advanced 802.1Q tunneling (double VLAN
Tagging)
technology. By using this feature, service providers can use
a
single VLAN to support customers who have multiple VLANs.
Customer
VLAN IDs are preserved and traffic from different customers
is
segregated within the service provider infrastructure even
when they
appear to be on the same VLAN. The 802.1Q tunneling expands
VLAN space by using a VLAN-in-VLAN hierarchy and tagging the
tagged packets. A port configured to support 802.1Q
tunneling is called a tunnel port. When you configure
tunneling, you assign a tunnel
port to a VLAN that is dedicated to tunneling. Each customer
requires
a separate VLAN, but that VLAN supports all of the
customer's
VLANs.
