Vision VES-1124

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 low-

bandwidth, 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 media-

rich applications possible.

Benefits

Application Diagram

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 bandwidth-

consuming 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.
