Testing deskReady to scope
What should the test prove?
01
Service activation and connectivity
02
Latency, stability and availability
03
Performance against agreed terms
Network performance verification
Test the technologies that carry the service.
From access and transmission testing to BERT, QoS and IP connectivity verification, the test scope follows the service risk you need to control.
02
Transmission testing
Assess E1/T1, E3/T3, SDH/SONET, ISDN, GSM, SS7 and Frame Relay transport services.
03
Optical network testing
Use OTDR and C/DWDM testing to examine optical links and transport infrastructure.
04
BERT and activation checks
Verify bit error rates and service activation before a circuit or link is accepted.
05
Performance and QoS
Measure availability, latency, stability and quality against technical or SLA parameters.
06
IP connectivity testing
Validate end-to-end IP reachability and service integrity across the operating path.
07
Workflow integration
Connect test evidence with the wider DDG service, project and reporting process.
A controlled testing path
A disciplined route from test plan to evidence.
The right instruments, test sequence and reporting standard are aligned before the field team begins measuring the service.
- 01
01 · Scope
Define the test question
Clarify the service, circuit, technology, site conditions and SLA evidence required.
- 02
02 · Prepare
Align instruments and access
Select the test suite, instruments, sequence, access plan and safety requirements before mobilization.
- 03
03 · Measure
Run the field verification
Capture repeatable measurements for connectivity, errors, latency, stability and service performance.
- 04
04 · Report
Review evidence and next steps
Receive a clear, tailored report that supports acceptance, remediation, design or contract review.
Useful starting point: Share the circuit or service scope, destination, SLA parameters, access requirements and any known fault pattern so the test plan can be focused from the start.
Technology coverage
Coverage across access, transmission and optical networks.
Testing can be shaped around the technology in service, the operating environment and the evidence required by the customer or contract.
Access technologies
Wireless, copper, ADSLx, VDSLx and SHDSL.
Transmission technologies
E1/T1, E3/T3, SDH/SONET, ISDN, GSM, SS7 and Frame Relay.
Optical networking
OTDR and C/DWDM testing for optical links and transport infrastructure.
Decision-ready measurements
Measurements that support the next decision.
Receive clear results for performance availability, transmission latency, link stability, service integrity and contractual verification.
Performance availability
Measured service availability and evidence that supports acceptance or remediation decisions.
Transmission latency
Latency and response findings that help teams understand the service experience end to end.
Link stability
Error, continuity and stability measurements that expose issues before they affect operations.
Service integrity
A clear view of whether delivered circuit parameters meet the agreed technical or SLA terms.
Frequently asked questions
Before you scope a test
A few practical answers for network operators, enterprise teams and project owners.
Can testing be performed at a remote site?
Yes. The testing model can be coordinated for remote and hard-to-reach locations, subject to access, safety and technology requirements.
Can you follow a specific test standard or suite?
Testing can be aligned to the relevant technical requirement, including RFC 2544 where it is appropriate to the service and acceptance criteria.
Can the final report be customized?
Yes. Results can be delivered with tailored graphical outputs and a clear documentation structure suited to the customer, project or operations team.
Test with confidence
Need independent evidence for the service?
Share the technology, location, test objective and SLA parameters. We will help shape a focused field testing plan.
