VMG4005-B50B, VDSL2 17a Bonding and 35b Single Line Bridge

Bonded VDSL2 with G.vector

The VMG4005-B50B supports VDSL2 bonding with vectoring of up to profile 17a and 35b. The vectoring support reduces cross-talk to increase performance and range by up to 150% for operators.

Comprehensive Routing with IPv6, QoS and Firewall

Zyxel offers excellent routing capabilities designed to meet service provider needs. The Zyxel VMG4005-B50B VDSL2 17a Bonding and 35b Single Line Bridge continues this legacy with full IPv4 support, IPv6/IPv4 Dual Stack and IPv6 Rapid Deployment (RD) for a strong foundation to implement advanced features including quality of service (QoS) functionality to categorize incoming and outgoing traffics in addition to a stateful packet inspection (SPI) firewall for end-user security.

TR-069 remote management

With TR-098/TR-181 data model for TR-069 standard management specifications, service providers are able to manage, configure and diagnose the client devices remotely without manual intervention of subscriber. This unique feature offers a true “plug-and-play” experience and reduces the complexity of deployment, therefore saving operation and maintenance costs for service providers.
