Release Note

February 23, 2015 Status: Controlled Availability

Carrier Ethernet Demarcation and Aggregation Device ETX­2 is RAD’s family of Carrier Ethernet demarcation and aggregation devices, delivering RAD’s Service Assured Access solution, by extending packet networks to the customer premises over various access infrastructure types. ETX­2 is ideal for carriers, mobile operators, and wholesalers seeking to offer their customers unified Ethernet business services, Layer­3 VPNs and TDM services, as well as value­added services using virtualization at the customer edge. ETX­2 includes the demarcation devices ETX­203AX, ETX­203AM, ETX­205A, ETX­220A, a 10GbE demarcation and aggregation device, and the new member ETX­2i, a next­generation hybrid Layer­2 and 3 demarcation device.

ETX­2 provides MEF CE2.0 E­LAN, E­Line, E­Tree, and E­Access Ethernet services over FE/GbE and 10GbE interfaces. It also offers the same services over SHDSL, PDH, and SONET/SDH access lines. The integrated bridge functionality ensures E­LAN delivery while maintaining the ability to define bandwidth profiles per flow (EVC.CoS). When using an integrated router, ETX­2 adds VRF­based L3 services, allowing mixed premium Layer­2 and Layer­3 services from a single unit, along with BGP and OSPF routing protocols, as well as BFD and VRRP.

Diverse flow classification, hierarchical quality of service (HQoS), and per­service queuing and scheduling mechanisms allow the service provider to offer multiple services using the same physical port with guaranteed SLA. Each service can be differentiated by rate limitation, traffic shaping per EVC, WRED per EVC.CoS, and traffic prioritization.

Featuring ultra­fast, hardware­powered processing, ETX­2 performs OAM and PM measurements at Layer­2 and Layer­3 with up to 1 microsecond precision, offering powerful benefits such as measuring and reporting bandwidth utilization per flow (EVC.CoS), and collection of unidirectional and bidirectional PM parameters (frame loss, delay, and delay variation) with Y.1731 and TWAMP standards. It also offers immediate detection of loss of continuity (LOC), triggering sub 50 ms protection switching in ring topologies (G.8032v2) and end­to­end service protection (G.8031).

ETX­2 provides these types of L2 OAM:

• Single­segment (link) OAM according to IEEE 802.3­2005, active and passive mode

• End­to­end connectivity OAM based on IEEE 802.1ag

• End­to­end service and performance monitoring based on ITU­T Y.1731

For SLA monitoring over L3 networks, ETX­2 offers two­way active measurement protocol (TWAMP) per RFC­5357 (TWAMP light). It provides one­way and two­way KPI, and can only be activated with a software license.

ETX­2 also offers diagnostics tools that include MAC and IP­based intrusive and non­intrusive loopbacks with MAC and IP swap, as well as advanced RFC­2544 and Y.1564 generators and analyzers for service activation tests that generate “birth certificate” reports.

ETX­2 Version 5.8

666-400-02/15 Full Version: 5.8.0(0.42) Page 2

Release Note

Furthermore, incorporating RAD’s SyncToP platform of synchronization and timing over packet feature set, ETX­2 utilizes standard technologies such as IEEE 1588v2 transparent clock (TC), slave clock, and boundary clock, as well as synchronous Ethernet to ensure highly accurate timing delivery in packet­based mobile backhaul networks. ETX­2 can also act as an IEEE 1588v2 Grand Master (GM) with an integrated GNSS receiver.

The D­NFV options of ETX­205A and ETX­2i integrate the HW­based ETX­2 NID functionality with an Intel x86 processor that hosts virtual machines providing virtual network functions (VFs) and value­added services. This enables service providers to quickly and easily introduce new services and implement new network capabilities, with the benefit of function localization at the customer premises. Additionally, a high­scale PM controller option with an Intel x86 core is available for ETX­205A. This ordering option offers monitoring for up to 2000 end points with layer­3 TWAMP sessions and more.

ETX­2 devices can be ordered in the following configurations:

• ETX­203AX – Carrier Ethernet demarcation device, providing Ethernet demarcation

• ETX­203AM – Universal Carrier Ethernet demarcation device, with a modular uplink design that enables carriers to provide universal homogenous Carrier Ethernet service while saving operational costs

• ETX­205A – Advanced Carrier Ethernet/mobile demarcation device. It can be ordered in a 19” or 8.5” enclosure with optional E1/T1 interfaces for pseudowire services, with several synchronization options (SyncE, 1588v2 slave or Grand Master with integrated GPS). It can also be ordered with an integrated router, a D­NFV module hosting virtual functions, or high­scale PM controller.

• ETX­220A – 10GbE Carrier Ethernet demarcation/aggregation device, providing 10GbE aggregation with 40 Gbps ingress and 30 Gbps egress capacity

• ETX­2i – Next­generation hybrid demarcation device. It can be ordered in a 19” or 8.5” enclosure, with fixed or modular uplink. It can also be ordered with a pluggable D­NFV module hosting virtual functions.

ETX­2 is managed via command line interface (CLI) and can also be managed by RADview management tools (EMS, SMS, and PM Portal), providing a user­friendly graphical user interface (GUI) for service creation, network management, and SLA monitoring and reports.

For a full list of the capabilities introduced in Ver. 5.8, see New Features.

Market Segments The ETX­2 intelligent demarcation unit is optimized for carriers, service providers, and wholesale providers seeking to offer SLA­based Ethernet services to business customers and for mobile backhauling applications, over different access technologies. It provides key functions at customer premises and multi­tenant units (MTUs), including robust bandwidth control mechanisms to classify, police, schedule, and shape high­priority traffic in order to prevent delay or discards even when the link is congested.

Release Note

multiple EVCs. In addition, the device incorporates Layer­1, 2, and 3 diagnostic loopback capabilities with MAC and IP address swap.

Mobile Demarcation Device for Mobile Backhauling Applications

For mobile backhauling services, ETX­2 is installed at the operator tower and controller sites, connecting the IP­NodeB or eNodeB to the packet network (see Figure 2). It features sophisticated traffic management and service assurance capabilities, including proactive service monitoring and fault identification throughout the entire network. Furthermore, statistics analysis allows backhaul wholesalers to effectively plan network capacity to overcome the “peak to mean” gap, such that bandwidth is added only when needed, based on actual usage. ETX­2 also backhauls legacy 2G and 3G E1/T1 traffic with TDM pseudowire services, offering a “one box solution” for mixed Ethernet and TDM services over a unified packet network.

Another important capability of ETX­2 is synchronization; ETX­2 integrated support of SyncE and IEEE 1588v2 PTP offers a diverse set of synchronization solutions such as pure SyncE­based frequency synchronization for 2G/3G networks and IEEE 1588v2 PTP­based frequency and phase synchronization for FDD and LTE networks. ETX­2 can even combine SyncE for frequency and PTP for phase, for the best possible performance. Frequency and phase synchronization are distributed to cell sites via SyncE and BITS, as well as TOD and 1PPS GNSS interfaces.

In cases where cell sites are equipped with built­in PTP capabilities, ETX­2’s SyncToP functionalities also include IEEE 1588v2 transparent clock (TC) or boundary clock (BC). Moreover, by offering grandmaster clock, it builds a true “distributed Grand Master” architecture for cost/performance optimization.

As all­in­one devices, RAD’s ETX­2 MDDs cut down provider costs by minimizing equipment needed for timing and demarcation.
