The ETX-5300A aggregates SLA-based wholesale services, Ethernet business services, legacy TDM service emulation, and mobile backhaul. It is also ideal for high capacity grooming of E-OAM and performance monitoring sessions.
The ETX-5300A powerful aggregation platform works opposite the ETX Carrier Ethernet demarcation devices and the IPmux TDM pseudowire gateways. Together, they provide a complete end-to-edge solution that allows carriers and service providers to easily migrate from SDH/SONET to packet technology and to converge voice and data services – both TDM and packet-based – over Ethernet, IP or MPLS networks. A true service delivery platform, the ETX-5300A supports “point-and-click” provisioning and delivers predictable performance with end-to-end SLA assurance.
Supported services include:
-
E-Line (EPL and EVPL) for LAN-to-LAN, VoIP and IP-VPN connectivity, as well as for storage and dedicated Internet access
-
E-LAN (EP-LAN and EVP-LAN) for multipoint Layer 2 VPN, transparent LAN services and multicast networks
-
E-Tree (EP-Tree, EVP-Tree) for rooted multipoint Layer 2 VPNs, broadcast and telemetry networks
-
2G, 3G, HSPA, and LTE transport
The 3U modular system features high port density for space-restricted facilities, delivering up to 100 Gbps of user throughput via the following interfaces:
-
Two redundant main cards, each housing four 10-GbE network ports
-
Up to four service cards, each housing 20 UTP or SFP 1-GbE tributary ports, four channelized STM1/OC-3 ports, or combinations
The ETX-5300A features non-blocking architecture, allowing wire-speed forwarding for all packet sizes. Designed for high availability and “always-on” service reliability, it includes port and power supply redundancy, with hot-swappable cards and modules, as well as in-service software upgrade capabilities. In addition, it supports carrier-grade service resiliency, as detailed below.
The ETX-5300A enables efficient handling of multi-priority traffic on a per-flow basis, with ultra-high capacity that enables simultaneous processing of thousands of service flows. The device enables multi-criteria traffic classification, as well as metering, policing and shaping to help carriers rate-limit user traffic according to predefined CIR (committed information rate) and EIR (excess information rate) profiles.
Enhanced quality of service is further supported by multi-level hierarchical scheduling mechanism that combines Strict Priority (SP) and weighted fair queue (WFQ) scheduling, to efficiently handle real-time, premium and best-effort traffic. The ETX-5300A also uses weighted random early detection (WRED) policy for intelligent queue management and congestion avoidance. Packet editing capabilities include 802.1ad Q-in-Q tagging and color-sensitive P-bit re-marking, which ensures metering continuity across coloraware and color-blind Metro networks and WANs.
The ETX-5300A features a comprehensive Ethernet OAM suite that includes Ethernet Service OAM (IEEE 802.1ag) and performance monitoring (ITU-T Y.1731).
Featuring ultra-fast, hardware-based processing capabilities, the ETX-5300A performs OAM and PM measurements in nanoseconds with maximum precision, offering the following powerful benefits:
-
Immediate detection of loss of continuity (LOC) to ensure sub-50 ms protection switching
-
Highly accurate frame loss measurements with live-traffic testing
-
Flow-level monitoring enables simultaneous processing of over 1,000 OAM sessions
-
Loopback testing at line rate
Its superior processing capabilities make the ETX-5300A an ideal termination and grooming point for Ethernet OAM and performance monitoring sessions.
The ETX-5300A offers advanced SLA assurance tools, including user-defined KPI (key performance indicators) threshold configuration for jitter, latency, packet loss and availability. Other tools include real-time SLA violation alerts and per-flow daily statistics reporting.
The ETX-5300A offers various tools to ensure five nines (99.999%) availability and sub-50 ms restoration in the event of network outages. These include dual homing link redundancy and Link Aggregation (LAG), as well as 1+1 APS protection on the TDM ports. In addition, the ETX-5300A supports Ethernet Ring Protection Switching (ERPS) per G.8032.
Incorporating RAD’s SyncToP synchronization and Timing over Packet feature set, the ETX-5300A utilizes standard technologies to ensure highly accurate clock recovery and distribution over both the physical and packet layers:
-
Synchronous Ethernet (Sync-E) master and slave clock support per ITU-T G.8261-G.8266, with primary/secondary clock redundancy
-
1588v2 Precision Time Protocol Grandmaster, transparent and slave clock with hardware-based timestamping as well as ToD (time of day) synchronization
-
1 pps, 10-MHz signal phase and frequency synchronization
The ETX-5300A’s exceptional SyncToP capabilities also include a built-in input/output clock interface and support for multiple clock domains. These provide exceptional value for wholesale mobile backhaul service providers, ensuring the required service quality – such as +/-16 ppb (parts per billion) accuracy – while eliminating the need for costly dedicated hardware.
The ETX-5300A features flexible management capabilities, including local management via an ASCII terminal (RS-232). In addition, remote management can be performed either inband using the network or user ports, or out-of-band using a dedicated management port, while maintaining separation between management and user traffic via the use of VLANs. Advanced FCAPS (Fault, Configuration, Administration, Performance, Security) and diagnostic tools are provided by RADview-EMS, RAD’s carrier-class element management system, via an SNMP-based GUI.
The ETX-5300A also supports a variety of access protocols, including CLI over Telnet, SNMP, Web server, and TFTP. Incorporated security features include Secure Shell (SSH), Web-based Secure Socket Layer (SSL), SNMPv3, RADIUS and Terminal Access Controller Access-Control System (TACACS+), as well as management access control list (ACL).
