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 Quality of Service (QoS), security and multicasting features, the IES-5000-chassis-based system facilitates telcos/ISPs 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. The IES-5000 Series is temperature-hardened and can be installed in street cabinet, suitable for outside plant deployment.
The IES-5000 is a 6.5U height and 10-slot chassis-based system with separated 5U splitter frame. Two of the 10 slots are reserved for MSC and the remaining 8 slots are for DSL, VoIP and Ethernet line cards.
The MSC has 4 GbE ports for uplink and subtending. With the subtending feature, the IES-5000 Series 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 and can be plugged in trunk or set to work in 1+1 redundant mode. Additionally, two MSC for link redundancy and failover support. In case when one MSC fails, the second MSC takes over control within 1 second.
The ADSL/ADSL2+ line cards have two options: 48 ports and 72 ports. G.SHDSL.bis and VoIP line cards have 48 ports, the VDSL2 line card comes with 24 ports and 48 ports and 20 ports for fiber-based Fast Ethernet line card.
ADSL line cards provide 48 ports and 72 ports with transmission bandwidth up to 25 Mbps/2.4 Mbps. ADSL line cards also provide G.bond port bonding to increase service range or double transmission bandwidth. VDSL line cards provide with a ADLS2+ fallback function (Annex A and Annex B) allow telco operators migrating existing ADSL2+ services to VDSL2 services seamlessly. SHDSL line cards provide 48 ports with transmission bandwidth up to 5.69 Mbps/22.76 Mbps/45.52 Mbps in ATM/EFM mode. VDSL line cards provide 24 ports and 48 ports with transmission bandwidth up to 100 Mbps/100 Mbps and 80 Mbps/20 Mbps via bonding. All DSL cards are hot swappable to ensure system stability.
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. 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.
The 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 will come up to alert the operators. 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.
The IES-5000 provides various management methods: local console port, Web-based configuration, Telnet, and SNMP v1/v2/v3-based NetAtlas Access (EMS). Included management functions are Alarm and Status Surveillance, Configuration Management, Performance Management, and Fault Management. The IES-5000 allows operators 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 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.
The 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.
