Key Benefits
POTP Evolution:
- VCL-1400 can seamlessly transition from 100% TDM to 100% Packet Box. It can be deployed as a TDM MSPP in SDH networks and can transport data traffic using GFP and LCAS.
- On the other hand it can be configured as a Packet Switch and deployed in Ethernet based networks. It can offer TDM services on these networks through circuit emulation.
- VCL-1400 can be deployed at gateway locations between TDM & Packet Networks and can help a network operators transition their services slowly from TDM based to packet based.
Ideal Environment
VCL-1400 can be used in the edge and the access part of the optical networks. It can be deployed as BTS or NodeB transport element in mobile networks and to build access and aggregation rings upto 10Gbps capacity.
VCL-1400 3-slot chassis can be deployed for enterprise services as a CPE or an access box. As a CPE it can provide GigE interfaces to customers, and offer L2 VPNs with QoS.
It can be used to extend L3 VPN services from a service router at central location to customer premises. VCL-1400 can be used in Triple play as a transport box, backhauling all the traffic from a DSLAM or CMTS towards the core. With support for GigE client ports and multicast, it provides sufficient bandwidth to the DSLAM and for Video distribution.
Flexibility:
Every operator and it's network has it's own needs and requirements. VCL-1400 with it's modular architecture provides one platform which can fit into a variety of needs. This also enables a pay as you grow model. Base chassis variants of 1U (3 slot) and 2U (7 slot) along with an expansion chassis are available. A variety of line cards for both TDM and Packet help the operator arrive at the most optimal configuration for a particular requirement.
MPLS-TP:
Label Switched Paths with MPLS-TP is becoming an important requirement for scaling the network for millions of subscribers and thousands of Services today. VCL-1400 provides MPLS-TP based pseudowires for traffic enginered traffic flows on trunks, which leads to better control over the packet traffic resulting in a more optimized network. This is key to lowering capex in today's cost competitive environments. MPLS-TP is also an enabler for path level protection and restoration on the network.
VCL-1400 also supports end-toend sub-50ms path level protection by supporting ITU-T G.8031 standard on MPLS-TP tunnels.
Advanced Ethernet Features:
VCL-1400 has best in class packet switching capabilities, in line with today's requirements. Ingress rate limiting ensures that every packet entering the network is within the SLA bounds agreed with the customer. This prevents one customer from congesting/choking the packet network. Each packet is classified, so that the appropriate network policies (like prioritization and scheduling) can be applied to each kind of traffic. Options for 8 CoS queues and scheduling algorithms ensure that there are sufficient options available to the network administrator to manage the data traffic efficiently. ERPS (Ethernet Ring Protection Switching) standardized by G.8032 provides 50ms protected packet rings for greater resiliency. Multiple ringlets can be configured, and multiple ring topologies of packet networks are supported.
Packet Synchronization:
VCL-1400 also support SyncE and 1588v2 for distribution of Synchronization information over pure packet networks. This is critical for deployment in mobile networks especially for LTE, where voice is packetized but synchronization is critical for cell handoff and for ensuring jitter-free voice calls.
Circuit Emulation:
As networks move from TDM towards packet, a few TDM circuits are expected to be required for a long time due to legacy reasons. It's not cost effective to maintain an entire TDM network for this small amount of traffic. VCL-1400 supports SAToP and CESoPSN for carrying this TDM traffic over a pure packet infrastructure.
