The OptiQNet 852 is a carrier ethernet demarcation device that provides reliable connectivity between customer and provider networks. It offers features to ensure transport, operation, and precision (TOP) such as VLAN tagging, QoS, OAM protocols for monitoring, and synchronization using PTP and SyncE. It also supports management functions, alarms and diagnostics, and protects existing TDM infrastructure investments.

1. By using the above QoS features together with real-time flow
monitoring, operators can hence have their network
resources under proper arrangement while providing
customers stable contracted bandwidth and satisfactory
networking experience.
Operation
Precautions need to be taken for operators to sustain reliable
Operation, more specifically the Operation, Administration
and Maintenance (OAM), and to react to network deficiencies
in time. The OptiQNet 852 offers triple protection, namely
802.3ah (Link OAM) and 802.1ag and Y.1731 (Service OAM) to
this purpose. The former focuses on single-hop link status
monitoring such as physical link down events and dying gasp,
while the latter two emphasizes end-to-end service assurance.
The 802.1ag, known as Connectivity Fault Management,
covers several types of messages such as Connectivity Check
(CCM), Loop Back (LB), Link Trace (LT), Remote Defection
Indication (RDI), etc, to perform scheduled or on-demand
maintenance operations over multiple maintenance domain
(MD) levels. The Y.1731 extends the maintenance realm from
functional examination to performance measurement (PM).
Through constant diagnosis on throughput, latency, jitter and
loss rate, along with the transport SLA provisioning, operators
can be confident of the end-to-end quality of connectivity.
Precision
The Operation functionalities can never be trustworthy
without precision. To complement this, the OptiQNet 852 is
enhanced with a hardware-based IEEE 1588-2008 (i.e. 1588v2
or PTPv2) synchronizer that can achieve a sub-microsecond
precision required by latency-related PMs, especially the one-
way latency measurement. The precision is sustained even
when multiple non-1588v2-capable switches are presented
along the way to the master. To maintain the frequency
consistency between base stations and the corresponding
radio controller in 2G/3G/LTE mobile networks, the
Synchronous Ethernet (SyncE) is employed to ensure proper
operations.
Transport
The basic requirement to meet for CE is the capability to
establish transport topologies, such as E-Line/E-Tree/E-LAN
mandated by MEF9, via transport channels named Ethernet
Virtual Connections (EVCs). The OptiQNet 852 utilizes gigabit
VLAN-based switching, rather than normal MAC-learning, to
ensure fast convergence of the above topologies observing
the spirit of 802.1aj (TPMR). The double-tagging (802.1ad)
support further enables the isolation of different customer
networks within one provider network, whose scalability in
terms of number of VLANs is strengthened to 4096 x 4096.
Another important transport technology involves the Quality
of Service (QoS) provisioning that distinguishes the CE from
ordinary Ethernet technology. To guarantee Carrier-grade
QoS the OptiQNet 852 is geared up with a specially designed
hardware capable of per-port/per-flow traffic engineering
such as Service-Level-Agreement (SLA) enforcement and CoS
mapping. The SLA enforcement is carried out by traffic
conditioners such as the burst-tolerant trTCM (two rate Three
Color Marker), policer/rate limiter, and shaper. Layer 2
frames are finally scheduled for transmission in a Strict-
Priority or Weighted Round-Robin fashion.

Achieving TOP is the best policy
The ever-advancing access technologies demand a solid
counterpart in the backhaul. As an emerging technology for
mobile backhaul transmission for LTE
and future 4G access networks,
the Carrier Ethernet requires
each component therein

Standard Service, QoS,
Reliability and
Scalability. All of these
correspond to the
three TOP dimensions
that the OptiQNet 852
EDD is dedicated to offer.
In all, the Fiberlogic OptiQNet 852 promises a comprehensive
set of features with a modest TCO (Total Cost of Ownership),
making operators’ Carrier Ethernet investment OpEx-saving
and revenue-generating.

The OptiQNet 852 further provides EMS (Element
Management System) -level functionalities such as neighbor
discovery (802.1AB-2009, latest version of the LLDP protocol)
and SNMP (with various MIBs) to ensure administrators’
global view on the managed EDDs. Integrated together with
the patent-pending RepiDep technology in our TOPviewTM
EMS, automated deployment is made possible with just a few
clicks away
To further reduce the processing delay and limitation caused
by software-based PMs, an RFC2544-capable H/W tester is
introduced as the wire-speed (GbE) traffic generator and
analyzer for Y.1731. Note that tests can be performed either
in-service (test flows co-exist with user flows) or out-of-
service (test flows only), depending on the current network
situation.
Backward compatibility to traditional TDM links
Whilst addressing the emerging Carrier Ethernet backhauling,
care needs to be taken to protect capital investment in the
existing T1/E1 infrastructure. The MEF9-compliant E-Line
mechanism is adopted to emulate a end-to-end leased line
using Ethernet connection. Adhering to the Pseudowire
Emulation Edge-to-Edge (PWE3) architecture, the TDM
signals are encapsulated at one end as payload into Ethernet
frames, transported via EVCs, and de-capsulated at the other
end to be recovered. Available PWE3 technologies include
CESoETH, CESoPSN* and SAToP*.
