The ETX-220A features two 10-Gigabit Ethernet network ports and a 10-GbE user port (hardware-ready for 1+1 redundancy). All ports are SFP+ or XFP compatible.
The ETX-220A 10G Carrier Ethernet mobile demarcation device combines an aggregation-site gateway with Ethernet demarcation functionalities to provide end-to-end service control and performance management across packet backhaul.
The ETX-220A combines Ethernet demarcation with test-head functionalities, featuring a complete Ethernet OAM suite that includes Ethernet Link OAM (IEEE standard 802.3-2005, formerly 802.3ah), Ethernet Service OAM (IEEE 802.1ag) and performance monitoring (ITU-T Y.1731). These are enhanced with a built-in RFC-2544 test generation engine, as well as Layer 1, 2 and 3 diagnostic loopback capabilities with MAC and IP address swap.
Featuring ultra-fast, hardware-based processing capabilities, the ETX-220A performs OAM and PM measurements in under 1 microsecond with maximum precision.
The ETX-220A offers advanced SLA assurance tools, including user-defined KPI (key performance indicators) threshold configuration, real-time SLA violation alerts and per-flow daily statistics reporting.
Designed to support RAD’s SyncToP synchronization and Timing over Packet feature set, the ETX-220A is hardware-ready for the following clock recovery and distribution capabilities:
-
Synchronous Ethernet (Sync-E) master and slave clock support per ITU-T G.8261-G.8264, with primary/secondary clock redundancy
-
1588v2 Precision Time Protocol slave and transparent clock with hardware-based timestamping 1 PPS, E1/T1 and 2 MHz signal frequency extracted from Sync-E, E1/T1 or 1588v2 slave
The ETX-220A features advanced softcore architecture for efficient handling of multipriority traffic on a per-flow basis, with ultrahigh capacity that enables simultaneous processing of hundreds 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 pre-defined CIR (committed information rate) and EIR (excess information rate) profiles.
Enhanced quality of service is further supported by a hierarchical scheduling mechanism that combines Strict Priority (SP) and weighted fair queue (WFQ) scheduling, as well as weighted random early detection (WRED) policy and colorsensitive P-bit re-marking packet editing.
The ETX-220A supports dual homing link redundancy and Link Aggregation (LAG) using 802.3ad LACP. In addition, path protection is supported with Ethernet Linear Protection Switching per ITU-T G.8031.
The ETX-220A 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 SNMPbased GUI.
The ETX-220A also supports a variety of access protocols, including CLI over Telnet, SNMP, 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).
