First, the network room status and rectification plan
The current situation of the existing weak current machine room cabinet is as follows (schematic diagram): The schematic diagram after rectification is as follows:
The network telephone wiring in the computer room has the following advantages after rectification:
A, the operation of VoIP system is more stable and reliable;
B, the maintenance of VoIP system is faster and more convenient;
C, it is more convenient and quick to add equipment after the system, which is convenient for the expansion and upgrade of the system in the future;
D, the whole weak current machine room and cabinet look neat and beautiful.
Second, the telephone program-controlled switch rectification scheme
The original telephones of group companies are all direct dial, so it is inconvenient for internal employees to communicate by telephone. Dialing each other will also lead to telephone charges, resulting in a waste of resources and inconvenient management.
It is suggested that the group company adopt a program-controlled telephone exchange that conforms to the modern office concept, and all telephones in the public office area are connected by extension telephones. All incoming calls are filtered by the front desk or answered and transferred by the computer operator, and the internal extension phone can be dialed freely; In addition to the extension telephone, the competent leader can also configure the direct dial telephone according to the actual situation of the company.
After the telephone system is rectified, it has the following advantages:
A, communication within the company is more convenient;
B, the telephone system maintenance is faster, more convenient and more flexible;
C, convenient for internal management of the company;
D, save phone bills and resources.
Three. Statistics on equipment, materials and expenses required for the whole renovation plan are as follows:
Before making budget statistics on the specific cost of the renovation, it is necessary to make statistics on the current operation of the internal jobs, the network of the computer room and telephone distribution frame, and the network equipment.
