Tollgrade VBT Manager

676 views

Published on

The VBT is a groundbreaking new handheld diagnostic tool used by field technicians that pinpoints the causes of repeat and chronic problems within your customer’s premises or in the local access network that disrupt or slow down broadband services, thereby eliminating unnecessary repeat dispatches and improving overall satisfaction. Now, with the addition of the VBT Manager, Broadband Service Providers can aggregate all the test results performed by the VBTs in the field, centrally store these results and measure compliance to field repair processes for the first time. This allows service providers to realize significant savings, reduce repeat dispatches, and measure compliance to their standardized repair processes.
