Description

Overview

 

2Gbps duplex backplane with high-bandwidth transmission

The VES-1616FE-55A provides up to two Gigabit Combo ports for the upper layer network connections. Since VDSL2 ports support only 100Mbps in a very short distance, VES-1616FE-55A can provide virtually non-blocking interconnections from the subscriber ports to the network interface ports in most environments and application scenarios.

 

Completed Ethernet VLAN and multicast functions

The VES-1616FE-55A provides Ethernet VLAN features for both security and performance purposes. A VLAN is used to isolate traffics between different users/applications in order to provide better security and performance. By limiting broadcast traffics within the VLAN broadcasting domain, the performance can be enhanced. The IGMP snooping function is provided in VES-1616FE-55A to prevent unnecessary multicast traffic forwarding to all subscribers, thus optimizing bandwidth utilization for multicast applications such as broadcast video.

 

MVLAN consolidates same video stream requested by different VLANs

The multicast VLAN feature checks all VLANs to see if some have requested the same video stream. If they have, only one request instead of many will be issued and the stream is distributed to all requesting VLANs. The total amount of the video streams can be reduced significantly as a result.

 

Service Differentiation from Rate Limiting

In order to fulfill different customer needs, service providers need a network infrastructure that combines guaranteed performance and flexibility in service provisioning. Upstream rate limiting on VDSL2 subscriber ports allows services to step up with 32 Kbps increments for service providers to offer tiered services.

 

Upstream Access Control Mechanism

The VES-1616FE-55A supports not only 802.1x port-based access control for subscriber authentication, but also defines a limited number of MAC addresses that can access the network from a particular port. This feature denies unauthorized access to the DSCAM to significantly enhance network security. Another access control feature is the capability to limit the number of users (MAC addresses) who can access the network simultaneously on a per-port basis, allowing service providers to offer flexible billing plans. Besides that, VES-1616FE-55A provides per-port packet classification rules based on the header information of up to layer 4 and corresponding action rules to manipulate the matched packets as needed.

 

DHCP Snooping

The VES-1616FE-55A provides a DHCP snooping mechanism to prevent users from using static IP addresses. If a port is DHCP-enabled, IP packets from the port cannot pass through the line card if the IP addresses of the packets are not leased by the DHCP snooping mechanism.

Expanded Revenue Opportunity

In addition to the VDSL2 PTM mode service, the VES-1616FE-55A also provides ADSL2+ fallback feature. When the feature is turned on, the DSLAM will detect if one of the customer devices is an ADSL2/2+ CPE, and the operation mode of the corresponding port is switched to ADSL2/2+, and a corresponding connection is established through the port to the customer device. This feature empowers VES-1616FE-55A to become a suitable solution for Telco operators to start the migration from ADSL2+ to VDSL2 services.

 

Double-tagging Service

The VES-1616FE-55A provides IEEE 802.1ad VLAN stacking functions. When enabled, the function can add the provider’s s-tag for incoming c-tag frames without checking c-tag value, add s-tag to untagged incoming frames, or add c-tag and s-tag simultaneously to untagged incoming frames. The added tags will be removed while the frames move toward subscribers. Moreover, different ports can apply the same s-tag and c-tag values. With the mechanism, operators can easily identify traffics from different users/applications and route the traffics to corresponding ISPs.

 

Various Band Plans Support Different Applications

The VES-1616FE-55A defines seven different VDSL2 profiles as below to suit a variety of different applications.

VDSL2 Profile Maximum Downstream Maximum Upstream
8a/b/c/d 85 Mbps 18 Mbps
12a/b 85 Mbps 45 Mbps
17a 100 Mbps 45 Mbps

The DS1 frequency band of the 17a profile starts at 138 kHz and the edge frequency of the upper band of the 17a profile is 17.664 MHz. The VDSL2 profiles are programmable and they can automatically adapt to each VDSL2 line according to the conditions.
