Warranty Services
From remote support to on-site troubleshooting, spare parts to proactive alerts — all-round assurance for stable IT operations.
Remote Technical Support
Fast response, remote diagnostics, first-time fault resolution
Phone Support
After receiving a service request we respond by phone within the response time of your service level, helping analyze, diagnose and locate the issue, providing solutions and guiding implementation.
Remote Access
For issues phone support cannot resolve, with user consent we log into the faulty device via remote terminal to collect data, analyze causes and propose fixes, with remote operation when necessary.
On-site Technical Support
For complex failures, engineers arrive fast and solve problems face to face
On-site Troubleshooting
Engineers respond rapidly, gather information to identify the cause, prepare tools and head on site to restore operations quickly. An Emergency Incident Report detailing cause, resolution and prevention follows.
Scheduled Inspections
Per service level and appointment, engineers inspect on premises regularly — diagnosing network device performance, analyzing resource trends, giving tuning advice and checking security risks. An inspection report is signed off afterwards.
Critical-moment On-site Support
For major events and special periods we follow "plan ahead, support on site", safeguarding network stability before, during and after. Holiday emergency measures keep dedicated staff on duty.
Resident Engineer Service
Full IT outsourcing for high-demand industries. The CMMI-based nationwide maintenance base spreads per-site costs; rich experience and multi-brand partnerships let customers focus on business and cut staffing costs.

Collaborative operations, real-time alerts — risks identified and removed early
