Tejas Networks

Technology	Description	Value to the Carrier
DBPR Ring Protection	Novel method to carry best-effort data as extra traffic in existing TDM protect channels	Unlock and double available work bandwidth in existing SDH microwave rings
EoPDH Aggregation with DS0 Grooming	High-capacity statistical aggregation of EoPDH and EoS traffic with DS0 level re-packing of E1s carrying voice traffic	Maximize reuse of PDH microwave while avoiding book-ended solutions; no stacking of EoPDH/EoS cards required
ERPS Ring Protection on SDH	Sub-50ms protection switching in Carrier Ethernet packet rings without reserving bandwidth	Double available ring capacity for carrying high-priority 3G traffic using both sides of SDH rings

Technology	Description	Value to the Carrier
3-level Hierarchical QoS with L3/L4 classification	Discriminate data traffic at three levels – port, tunnel and service marker; granular rate shaping based on deeper inspection	Support more monetizable flows for the same aggregate traffic and better segmentation of customers for higher profits
PBB with Carrier Ethernet OAM and ERPS	Carrier-grade version of “plug-and-play” Ethernet with network and service scalability	Launch multicast services like Mobile TV. Offer SLA based services to Enterprises
Open Ring ERPS	Sub-50ms protection switching in “partial” rings or chains while subtending on L2 or IP networks	Limit bandwidth upgrade costs in Aggregation and Core by realizing “open”packet rings

Technology	Description	Value to the Carrier
Circuit Emulation (SAToP/MEF 8, CESoPSN)	Transparent or “Structure-aware” carriage of TDM circuits on Packets	Lower network complexity and operational costs by dismantling legacy TDM infrastructure
Packet Synchronization (SyncE, 1588v2)	High-quality transport of a synchronization clock signal over a physical or packet layer	Assure excellent QoE to voice users and reduce churn. Time-of-Day delivery for SLA monitoring
Connection-oriented L2, OAM and 1+1 Line Protection (PBB-TE, MPLS-TP, ITU G.8031)	Capability to create deterministic, protected tunnels on a Carrier Ethernet network with point-and-click provisioning from a central NMS	Offer advanced real-time and CBR services in LTE with stringent latency/jitter/packet loss thresholds and sub-50ms linear protection switching
