With increasingly high bandwidth applications, physical access devices have to be verified to comply before deployment.
Network subscribers continue to demand a wider array of services, including real-time entertainment and other loss- and latency-sensitive applications. As a result, greater demands are placed on the last mile. Providers have to deliver an excellent Quality of Experience over an existing infrastructure that often is less than perfect with various levels of network impairments. With increasingly high bandwidth applications like video, physical access devices have to be verified to comply before deployment.
What to Test
Real world noise such as crosstalk, RFI, impulse and white noise has a dramatic impact on the performance of modems and DSLAMs. The effect of these impairments on your solution must be tested to validate:
- Compliance—test to the requirements of standards bodies: ATIS, DSL Forum, ETSI and ITU-T
- Throughput—data rates in the presence of impairments such as insertion loss, delay/phase and input impedance
- Quality of Experience—quality metrics in the presence of impairments
- Turn-up—in-house quality testing for MoCA, ADSL/VDSL. DOCSIS and RF Video
Spirent offers fixed access network performance testing solutions to help you reduce crosstalk, RFI, impulse and white noise:
