VCL-1400P: E1 / SDH Packet Transport Network

Packet Synchronization:

VCL1400P supports SyncE and 1588v2 for distribution of synchronization information over pure packet networks.

Circuit Emulation:

As more services move from TDM to Ethernet, a few TDM circuits are expected to remain in the network for specific customer services and support of legacy infrastructure. Circuit Emulation reduces the cost and simplifies the management of these services using an all Packet Transport Network. The VCL1400P supports E1 SAToP and STM-1 CEP for carrying this traffic with the reliability and performance of legacy TDM networks.

Packet Transport:

Using the next generation in Packet Transport Network (PTN) technology, the VCL1400P is a 1U packet aggregation solution designed for edge and access applications in the network. With a full PTN feature set enabling end-to-end pseudo-wire and Ethernet multipoint services the VCL1400P has the advanced features for tomorrow's mobile backhaul, enterprise, business, data center, cloud and infrastructure services.

Advanced Ethernet Features:

VCL1400P provides best in class packet switching to create networks with the highest performance. Ingress rate limiting ensures that every packet entering the network is within the SLA bounds preventing any one customer / service from congesting / choking the network. Each packet is classified so that the appropriate network policies (like prioritization and scheduling) can be applied. Eight CoS queues and scheduling algorithms ensure that there are sufficient options available to manage the data traffic efficiently. Standard G.8032 ERPS (Ethernet Ring Protection Switching) provides 50ms protected packet rings for greater resiliency. Multiple ringlets and multiple ring topologies are supported.

MPLS-TP:

MPLS label-based connection-oriented Ethernet allows networks to easily scale from a few subscribers to millions of subscribers and a few services to thousands of services. The VCL1400P provides MPLS-TP based for engineered traffic flows on trunks, optimizing the network by providing the right amount of packet traffic control. The cost benefits of stat-muxing are combined with traffic engineering to lower CAPEX. OPEX reductions come through faster provisioning, robust protection and quicker root cause analysis during failures.

Ethernet OAM:

Allows real-time monitoring of end-to-end circuits, connections or trunks, enabling quick detection and isolation of faults to a particular subnet, trunk, link or node. The VCL1400P supports BFD based Fault OAM and ping/ traceroute at tunnel/ pseudowire level. It also supports MPLS-TP based performance OAM for MPLS-TP based PW services. For .1q/,1ad based MEF services, Y.1731/802.1ag based CFM OAM (Port level down MEP) and Y.1731 PM counters are supported.

Flexible Network Architectures:

The VCL1400P has a flexible architecture that allows it to build the network best suited for all services. Linear for rapid deployment. Hub and spoke for cost effective aggregation. Ring and ringlet for high utilization and resiliency. Meshed for low latency and flexible protection. This is achieved with a unique combination of functionality including the ability for every optical port to be a UNI or an NNI.
