VES-2500
4U Modular QAM 2-band
VDSL Switch
The VES-2500 is QAM-based 2-band VDSL switch, a scalable platform for
delivering VDSL service. Flexible configuration of the VES-2500 allows
for maximum scalability to meet a range of requirements. It is well suited
for a variety of installation scenarios including campuses, central offices,
and multi-tenant unit (MTU) applications.
The VES-2500 has a 6-slot chassis, which enables administrators to add
resources, as they are needed. Service providers can start with one VLC1124A
VDSL line card, and add more VDSL line cards to increase deployment as
the number of subscribers increase. Such flexibility minimizes the initial
investment.
With the help of external Ethernet switches, the VES-2500 can be filled
simultaneously with six VDSL line cards to support up to 144 subscribers.
The external switches not only allow more users on one chassis, but also
help increase convenience when network topology or network interfaces
change. ZyXEL presents a full range of Dimension switches with different
port densities and various WAN connection interfaces.
The IEEE 802 standard-based firmware in VLC1124A VDSL line card provides
a rich set of features and ensures interoperability with equipments from
other vendors. The firmware includes advanced features such as bandwidth
management, 802.1X, IGMP snooping, and MAC address filtering to enhance
service differentiation, network security and bandwidth utilization.
The advanced design of the VLC1124A enables service providers to quickly
supply broadband service to a high number of customers at lower costs
than previously possible.
Benefits
External Switches Enhance
Flexibility
The VES-2500 uses external Ethernet switches to aggregate traffic from
different VDSL line cards. Each VLC1124A has one Fast Ethernet interface
for connecting to Ethernet switches. ZyXEL offers a full range of Dimension
Ethernet switches with different port density and various WAN connection
interfaces. This gives service providers a great amount of convenience
and flexibility when network topology or network interfaces change.
VLAN Offers Both Security
and QoS(Quality of Service)
The VLAN feature in the VES-2500 offers the benefits of both security
and performance. VLAN is used to separate traffic from different users
and to provide better security. Different services can be tagged and
mapped into different priority queues. Thus, Quality of Service can
be achieved and improved.
Multicasting Optimizes Bandwidth
Utilization
Multicasting design forwards traffic only to the subscribers who request
the multicast traffic. This restricts unnecessary broadcast traffic
to all subscribers and optimizes bandwidth utilization for bandwidth-consuming
applications such as video on demand. New mechanisms, such as 802.1p,
have also emerged to ensure the quality of service.
Rate Limiting Allows Service
Differentiation
In order to fulfill the needs of different customers, service providers
need a network infrastructure that combines guaranteed performance
and flexibility in service provisioning. Rate limiting on both Ethernet
and VDSL ports allow service providers to offer tiered service. |
