4TEL^®

DT-Extended Test

4TEL XT extends the capabilities of the basic demand test by giving the user an additional level of troubleshooting tools. The Tier 2 (back office) or field technician can now perform diagnostic testing that identifies service impairments that normally can’t be addressed by a single demand test. These types of impairments often occur with degrading or intermittent line conditions or can be a result of consumer equipment problems.

4TEL XT adds the following capabilities to those available with the demand test:

• Repeat Testing
• Pair ID Tone Generation
• Continuous Testing
• Inward Dial Testing
• Station (Equipment) Testing
• Ring/Talk Monitor

The 4TEL XT option also includes batch testing capability. Batch testing allows a specific set of lines to be scheduled for demand tests. Batch testing is often used to verify copper loop integrity after significant network changes have occurred; for example, when a cable cut has been repaired or a new carrier system deployed.
