ZyXEL VLC1348G-51 Ethernet LAN ADSL wired router

VLC1348G-51, 48-Port, Gigabit Ethernet, VDSL2, POTS Future Proof Architecture
As the flagship of ZyXEL's MSAN product portfolio, the IES-6000 is equipped with non-blocking Gigabit backplane, failover-enabled Management Switch Cards (MSC), dual input power modules and various high-port density multi-purpose line cards. With comprehensive IP-centric firmware features, the IES-6000 is a high-capacity system that facilitates Telco/ISP to deliver high-quality residential or business user services experience at competitive CAPEX/OPEX as well as satisfying its current and future infrastructural requirements of reliability, flexibility and scalability.

Easy & Reused Logistics
The IES-6000 is a 12.5 U-height, 17-slot chassis-based multi-service access node capable of adopting the same line cards as those for IES-5005/5000 systems.The MSC1024G control card with eight 1G uplinks is designed to plug into slot 8 and/or slot 9, while the remaining slots are available for equipping various line cards. The new MSC1224G control card is with two 10G and six 1G Ethernet uplinks to support even larger bandwidth requirement. The variety of line cards are including 48-port or 72-port ADSL2+ line cards that provide subscribers with asymmetric transmission bandwidth up to 25Mbps/2.4Mbps; 48-port SHDSL.bis line cards with symmetric transmission bandwidth of 5.69 Mbps per port; 24-port and 48-port VDSL2 line cards that offer up profile 17a (100Mbps/45Mbps) high-speed connectivity per port over copper; 48-port VoIP line card that supports either H.248 or SIP protocol and 20-port fiber-based Fast Ethernet line card that supports 100 Mbps transmission speed per port. The primary designed concept of IES-6000M is also taking account of the further technology evolution such as PON.

Advanced Triple Play and Mass Deployment Functionality
The IES-6000 inherits all the Layer 2 and Layer 3 QoS, security and multicast functionalities from the IES-5000/5005, while the following new features are added to satisfy the requirements for massive field deployments: (1) IP bridge functionality that alleviates the Layer 2 access network deployment restrictions resulted from MAC address table limitation and security attack issues; (2) ARP Proxy which minimizes the ARP broadcast requests to all subscribers; (3) TACACS+ mechanism to support remote authentication with TACACS+ servers; (4) VLAN-aware DHCP snooping which adds VLAN information into DHCP snooping tables; (5) DHCP option82 sub-option2 for providing remote client ID information to DHCP servers for flexible IP address assignment. (6) Cluster management feature that is able to reduce the OPEX of multiple DSLAM maintenance.

Robust Physical Safety Design
The IES-6000 supports 1+1 MSC redundancy with a failover switch time less than 1 second. In addition, voltage, temperature and FAN speed sensors are fitted into the system. When an abnormal condition is detected, the LED displays and/or the corresponding alarms will alert administrators of the situation. In case the system temperature rises over the preset threshold, thermal cutoff protection will kick in to shut down the system automatically.

Sophisticated OAM&P Features
The IES-6000 provides various management methods: local console port, Web-based configuration, Telnet and SNMP v1/v2/v3-based EMS (NetAtlas Access EMS). The management functions include Alarm and Status Surveillance, Configuration management, Performance management and Fault management. The IES-6000 allows multiple administrative accounts with 3-level access privileges. Accounts with the first-level privilege have full access to all management objects on the Management Information Base (MIB). Second-level accounts have similar access rights except creating new administrative accounts, while the third-level accounts are granted read-only access rights to the MIB objects. NetAtlas Access EMS also provides view-based MIB management that partial MIB objects can be defined and accessed for customization and security reasons. In addition, Cluster Management enables multiple DSLAM administration with single/master IP address, XML-based northbound interface is equipped to interoperate with external OSS systems.
