A network switch is a computer networking device that links network segments or network devices. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3) and above are often called layer-3 switches or multilayer switches. A network switch is made up of network switch components.

Service Aware
As a flagship product line of ZyXEL IP DSLAM, the IES-5000 Series is equipped with non-blocking gigabit backplane, failover-enabled Management Switch Cards (MSC), dual power modules high-port density DSL line cards and VoIP line cards. With embedded IP-centric QoS, security and multicasting firmware features, the IES-5000 is a chassis-based system that facilitates Telco/ISP delivering high degree of quality of experience to today's demanding residential and business customers, and achieving its infrastructure provisioning criteria of reliability, flexibility and scalability at competitive CAPEX/OPEX.

ZyXEL's IES-5000 is a 6.5RU height and 10-slot chassis-based system with separated 5RU splitter frame. Two of the 10 slots are reserved for Management Switch Cards (MSC) and the remaining 8 slots are for DSL line termination cards and VoIP line cards. The ADSL2/ADSL2+ line cards have two options : 48-ports and 72-ports; G.SHDSL.bis/VoIP line cards have 48 ports and the VDSL2 line card comes with 24 ports. In a standard rack, you can install up to 7 units without a splitter chassis or up to 4 units with a splitter chassis. The MSC has 4 GE ports for uplink and subtending. With the subtending feature, the IES-5000 can be cascaded in the rack at a central office, or be connected to remote IES products in the form of a tree, ring, or daisy-chained as needed. The uplinks can be used as a traffic aggregation trunk or set to work in 1+1 redundant mode. Additionally, install two Management Switch cards (MSC) for link redundancy and failover support. In case when an MSC fails, the second MSC takes over control within 1 second.

Multiple Standard DSL Services
Five hot swappable DSL line cards (ADSL2+ over POTS, ADSL2+ over ISDN, G.SHDSL, and VDSL2) are available. The ADSL2+ over POTS and the ADSL2+ over ISDN give subscribers with asymmetric transmission bandwidth of up to 25Mbps/1.2Mbps. The G.SHDSL.bis provides symmetric transmission bandwidth of 4.096 Mbps, 8.192 Mbps or up to 16.384 Mbps (similar to a lease line). The VDSL2 offers up to 65Mbps/35Mbps high speed connectivity per port with various loop distances over copper wiring.

Advanced triple Play Functionality
The IES-5000 provides complete ATM QoS (UBR/VBR/CBR) and Ethernet L2 QoS on the line cards. The IP QoS (Packet classification/Rate Limiting/Queue Scheduling) is provided on the Network Termination cards as well. Sophisticated PVC to VLAN bridging and aggregation enables end-to-end QoS and various service allocation and provisioning. In addition, the IES-5000 supports non-blocking traffic forwarding and multicast features with up to 256 multicast groups and 576/384/192 members per group. The IES-5000 can process more than 30 multicast IGMP join/leave requests per second and the maximum channel processing time is less than 250ms. For security, the IES-5000 provides anti MAC/IP address spoofing, broadcast storm prevention, MAC count limiting, and policy-based packet filtering. All these features allow ISPs/Telco operators to provide High Speed Internet access, VoIP, Near VOD, Broadcast TV and TV on demand, and other features easily.

Robust Physical Safety Design
ZyXEL's IES-5000 guarantees physical safety by embedding voltage, temperature and FAN speed sensors. When an abnormal condition is detected, the LED displays and/or the corresponding alarms alert you to the situation. In cases when the system temperature goes higher than the configured threshold, thermal cutoff protection kicks into action and the system will shut down automatically.

Sophisticated OAM&P Element Management System (EMS)
ZyXEL's IES-5000 provides various management methods: local console port, Web-based configuration, Telnet, and SNMP v1/v2/V3-based EMS (NetAtlas Access EMS). Included management functions are Alarm and Status Surveillance, Configuration management, Performance management, and Fault management. The IES-5000 allows you to create multiple administrative accounts and 3 levels of access rights. Accounts with the first-level privilege have full access rights. Second-level privilege accounts have the same access rights as first-level accounts except for account management. Third-level accounts can only view configuration settings and performance statistics. NetAtlas Access EMS also provides view-based MIB management and XML-based north bound interface. These features allow Telco operators to provide wholesale service to smaller CLECs and ISPs.

Distributed and QoS-assured Media Gateway
The ZyXEL IES-5000 provides a parallel and distributed media gateway architecture to empower VoIP services taking advantage of POTS voice signals, in addition to FAX and modem services. With the architecture, each media gateway serves up to 48 POTS ports and operates independently with each other. As part of the benefit, there is no throughput bottleneck or single-point failure issue in this architecture, the performance and reliability of the VoIP/fax/modem services are outstanding as well. The media gateway provides G.711, G.723, G.726, G.729a/b and T.38 codecs while RFC3261 SIP and H.248 network signaling protocols are supported as well.
