24-port QAM 2-band VDSL Switch
Recently, Ethernet has been more widely used for access applications, transport, and backbone infrastructure.
More service providers are adopting Ethernet as the first mile (EFM) in their FTTB/C deployments. Among different EFM
technologies, EFM over copper is filling the bandwidth gap between high-speed, Metro fiber networks and lowbandwidth, copper-based services. It utilizes existing copper wires, thus giving service providers a cost-effective solution
today, tomorrow, and beyond. Furthermore, EFM uses mature Ethernet technology that allows seamless connectivity
between enterprise Ethernet LANs and the WAN.
As influential as EFM, Ethernet over VDSL has changed the fundamental economics of broadband services for the last mile
and the MTU market. With Ethernet over VDSL, small to medium sized corporations can receive the same high
bandwidth services as large companies. Additional benefits include the ability to enjoy the video, data, and voice
services, which VDSL allows, eliminating the limitations of low bandwidth. VDSL delivers cost-effective, high-bandwidth
broadband access to enterprise campus and multi-tenant buildings (commercial buildings, residential buildings, hotels,
and etc.) without new wiring.
ZyXEL’s VES-1124 is a 24-port VDSL switch based on Quadrature Amplitude Modulation (QAM) and the latest Ethernet
technologies. The VES-1124 aggregates traffic from ZyXEL’s Prestige 841-25 QAM-based VDSL CPE, and multiplexes data
traffic into two 10/100Base-Tx uplinks that connect to any third-party Ethernet switch or WAN router. The built-in
POTS/ISDN splitter splits and sends the voice traffic to the PSTN. The VES-1124 supports up to 15Mbps for both
downstream and upstream, extending Ethernet service up to distances of 1.5km.
The IEEE 802 standard-based firmware provides a rich set of features and ensures interoperability with equipment from
other vendors. In addition, the firmware includes many advanced features such as bandwidth management, 802.1X,
IGMP snooping, broadcast storm control, and MAC address filtering, which enhance service differentiation, network
security and bandwidth utilization.
With a broad array of fully integrated, advanced technologies, the VES-1124 together with the Prestige 841-25 enable
service providers and system administrators to affordably build up full service networks and to make all kinds of mediarich applications possible.
Benefits
Port Trunking Provides Higher Availability
TheVES-1124 supports IEEE 802.3ad with load distribution
control and fail over recovery. The VES-1124 distributes traffic
to each trunk port based on the source and destination MAC
addresses, and thus balances the traffic load.
VLAN Offers Both Security and QoS (Quality of Service)
The VLAN feature in the VES-1124 offers the benefits of both
security and performance. VLAN provides better security by
isolating traffic between different users. Different services can
be tagged and mapped into different priority queues. Thus,
Quality of Service can be achieved and improved.
Multicasting Optimizes Bandwidth Utilization
The IGMP snooping feature only forwards traffic to
subscribers who request multicast traffic. This prevents the
unnecessary forwarding of multicast traffic to all subscribers,
thereby optimizing bandwidth utilization for bandwidthconsuming application such as broadcast video.
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.
Access Control Enhances Network Security
The VES-1124 supports not only 802.1x port-based access
control for subscriber authentication, but also allows system
administrators to define a limited number of MAC addresses
that can access the network from a particular port.
This feature denies unauthorized devices from accessing and
communicating through the switch, highly enhancing network
security. An additional access control feature is the capability
to limit the number of users (MAC addresses) that can access
the network simultaneously on a per-port basis, allowing the
service provider to offer flexible billing plans.
Clustering Simplifies Network Configuration and Management
The clustering management design enables system
administrators to configure and manage up to 24 units of the
VES-1124 through a single IP address. This enables service
providers to start with a minimal initial investment and add
more equipment as customers increase. Network expansion
can be accomplished without increasing management efforts.
Configuration and Management Simplifies Daily Operation
The VES-1124 also offers service providers extensive
management capabilities. The Web-based management
interface of the VES-1124 offers an easy-to-use platform,
independent management, and configuration options.
The VES-1124 supports SNMP and MIBs, both of which can
be managed via standard-based management software.
In addition to remote management capabilities, a console port
is available for local management.
