VeEX now has available two new modules for its TX300 test set, one for MPLS-TP, which is becoming increasingly popular for performing cellular backhaul, the other for CPRI.

The former can be used to test implementations of Multi-Protocol Label Switching Transport Profile (MPLS-TP). The latter addresses Common Public Radio Interface (CPRI) rates from 614.4 Mbps to 9.8304 Gbps.

MPLS-TP, a Layer 2 packet-based transport mechanism, is gaining momentum as a transport of choice for access and aggregation networks requiring a technology that combines the operational simplicity of packet switched networks with the operations, administration and maintenance (OAM) tools and fault resiliency capabilities of circuit switched networks.

A key application of MPLS-TP is mobile backhaul transport, as it is able to efficiently handle multiple classes of service, while providing simple provisioning and fault resiliency features needed for backhaul of 3G/4G LTE cell sites.

The TX300 offers the tool set for testing multiple classes of MPLS-TP traffic, measuring QoS parameters while simultaneously validating OAM functionalities. Available as a software upgrade option for the TX300 platform, the capabilities include:

  • MPLS-TP line rate traffic generation on any test port from 10BaseT up to 10G Ethernet
  • Support for LSP and Pseudowire
  • Dual Port MPLS-TP traffic generation
  • MPLS-TP traffic analysis, including all SLA key parameters (frame loss, delay, jitter, etc.)
  • MPLS-TP support for all Ethernet tests: RFC2544, V-SAM (Y.1564), Multi-stream throughput test and BERT
  • OAM support per ITU-T G.8113.1

Complementary to the TX300 platform’s extensive set of mobile backhaul testing capabilities, VeEX has also increased its support for mobile front haul technology with support for CPRI testing.

The CPRI software option for the TX300 provides service assurance verification for the CPRI Physical layer between the Radio Equipment Controller (REC) and the Radio Equipment (RE). It includes Bit Error Rate (BER) testing capabilities and latency measurement on rates from 614.4 Mbps to 9.8304 Gbps.
