ZyXEL ALC1248G-53 Ethernet LAN ADSL wired router

ALC1248G-53, Gigabit Ethernet, ADSL2/ADSL2+, Annex B, 48-port Future Proof Architecture
As the flagship of ZyXEL’s IP DSLAM product portfolio, the IES-6000 is equipped with non-blocking Gigabit backplane, failover-enabled Management Switch Cards (MSC), dual input power modules and various highport 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 25 Mbps/2.4 Mbps; 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 (100 Mbps/45 Mbps) high-speed connectivity per port over copper wires; 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: IP bridge functionality that alleviates the Layer 2 access network deployment restrictions resulted from MAC address table limitation and security attack issues; ARP Proxy which minimizes the ARP broadcast requests to all subscribers; TACACS+ mechanism to support remote authentication with TACACS+ servers; VLAN-aware DHCP snooping which adds VLAN information into DHCP snooping tables; DHCP option82 sub-option2 for providing remote client ID information to DHCP servers for flexible IP address assignment. Cluster management feature that is able to reduce the OPEX of multiple DSLAM maintenance.
