Carrier Ethernet : TJ2050

High Reliability Carrier Ethernet Access/Aggregation Switch



Overview: TJ2050 is a fully redundant access/aggregation switch which is ideal for aggregating sub-GigE data traffic onto a 2-4 Gbps packet ring. It incorporates 32 Gbps of packet switch distributed over two packet fabrics. 16 ports of 1GigE are supported in TJ2050.

Ideal Environment: TJ2050 is ideal for building 2-4 Gbps packet aggregation rings for a variety of applications like 3G backhaul, broadband aggregation and enterprise services. The sub-GigE rate traffic typically comes from the access devices (3G base stations, DSLAMs ,CMTS or Ethernet access switches) and is aggregated by the TJ2050.


High Reliability: Having support for redundant power and redundant switch fabrics ensures that TJ2050 has no single point of failure in ring configuration. This is important for mission critical applications.

50ms protection: With support for ITU-T G.8031 and G.8032, TJ2050 supports both path and ring protection within 50 ms. This enables reliable and disruption free connectivity for mobile base stations and high ARPU segments like banking & finance, and for VOIP and Video conferencing customers

Connection oriented Ethernet: TJ2050 supports connection oriented ethernet which enables traffic engineered end-to-end circuits to be provisioned across the network. These circuits can have service parameters like CIR (committed information rate),EIR (excess information rate) and 50ms protection. The concept of a connection in a packet switched network is very useful for providing tunnels for specific applications, providing bandwidth and latency guarantees, and for security.

Ethernet OAM: Allows real-time monitoring of endto-end circuits, connections or trunks, enabling quick detection of faults and isolating of fault to a particular subnet, trunk, link or node. Leads to substantial Opex savings

Hierarchical Quality of Service: Allows Service Provider to control bandwidths and latencies on a per service and per application level. Thus within a single service, bandwidth, latency and reliability guarantees can be provided per application. By mixing and matching these parameters, new revenue generating services can be offered or existing services can be differentiated

Built-in CWDM support: N x GE spurs and rings can be run on a single physical fiber infrastructure.
