Reduce OpEx with Loopback Testing

As more SIP-based services are deployed, Service Providers face difficulties proving to their customers that SLAs/SLOs are being met. What’s worse is that as VoIP migrations continue, network operators must proactively ensure that new services aren’t impacting the quality of their existing services. And finally, how do they go about troubleshooting a problem when a customer calls to complain? Costly truck rolls or equipment replacement only add to their cost.

VoIP Service Delivery
You’ve convinced your end-subscriber to deploy VoIP promising them that they’ll see no difference in their phone quality in addition to the new supplementary services to make their lives easier. Great! But how does your technician or even your customer know that their new service is truly ready to go? Using Tektronix’ DirectQuality Active Assurance solution, a loopback test can be performed on the VoIP end device to create a “birth certification” report that confirms the initial service quality.

Proactive Monitoring
We no longer can throw bandwidth at our problems. And let’s face it, we don’t have an infinite amount of bandwidth to deliver our data, video, and voice services without any type of bandwidth management. Just ask the operators who sell the iPhone. Wouldn’t it be nice to monitor your VoIP service to make sure quality hasn’t been affected since the day it was born? Use proactive loopback testing to cover the full subscriber base and ensure that any changes to your network have little impact on your end-subscriber compared to the day it was installed. The reduction of customer service calls that your end-subscribers make can more than pay for such a test system.

Troubleshooting and Fault Isolation
Chasing a particular problem in the field could take hours or even weeks. By that time your irate customer is looking at the competition. Tektronix’ Active Assurance solution deploys probes at key network segments to perform tests to isolate issues in your network. More importantly, many VoIP equipment vendors adhere to the same industry standard loopback specification giving you the ability to perform loopback tests at intermediary devices. The result? You reduce costs AND efficiently isolate problematic issues.
