Who is responsible for installing telephone jumpers?

Network and telephone lines are managed by the Ministry of Information Industry.

The specific wiring and installation services are provided by the corresponding companies, such as China Telecom, China Railcom, and China Unicom. Their door-to-door service employees seem to be called technicians, and they are neither network managers nor electricians. Since the network is being set up by an enterprise unit, it is better to report it to the human resources department to recruit professionals. Not only does it set up network cables, but it can also assist network managers in maintaining local area networks and servers in the future.
