Service Aware
As a flagship product line of ZyXEL IPDSLAM, the IES-5000/5005 Series is equipped with non-blocking gigabit backplane, failover-enabled Management Switch Cards (MSC), dual power modules and high-port density DSL line cards. With embedded IP-centric QoS, security and multicasting firmware features, the IES-5000/5005 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.

Scalability
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. The ADSL2/ADSL2+/G.SHDSL.bis line cards have 48 ports while 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.

The compact design of IES-5005 offers a 4RU-height and 5-slot chassis-based system with a separated 3RU splitter frame. One slot is reserved for an MSC card and the remaining 4 slots are for DSL line termination cards. The ADSL2/ADSL2+/G.SHDSL.bis line cards have 48 ports while the VDSL2 line card comes with 24 ports. In a standard rack, you can install up to 10 units without a splitter chassis or up to 6 units with a splitter chassis. The IES-5005 supports remote terminal (RT) and uses the same MSC and line cards as the IES-5000.

Multiple Standard DSL Services
Four 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 25 Mbps/1.2 Mbps. 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 65 Mbps/35 Mbps high speed connectivity per port with various loop distances over copper wiring.
