- The digital telephone exchange equipment is divided into a basic chassis and an expansion chassis.According to the user's specific configuration needs, it can be implemented through the basic chassis or basic chassis + expansion chassis.The basic chassis has nine line interface slots for expansion. The frame has 13 slots. The entire system uses a flexible bus resource allocation mechanism. The basic frame and the expansion frame each have two data buses. The system flexibly allocates resources based on the insertion of different interface boards according to the slot. If required, between the two buses Resource sharing can be performed. Furthermore, the expansion frame can also share resources with the basic frame, that is, the system's resources are intelligently allocated by the system.
The power module uses luna2. In the basic frame, users can flexibly adopt 1, 2, and 3 modules according to the number of interface boards to meet the system power supply requirements and redundant configuration. In the extension box, a maximum of 4 luna2 modules can be configured as required. The system board provides dual serial ports, which are used for maintenance, external printers, and some third-party applications, such as cti and hotel interfaces. If you need remote maintenance and isdn as the clock master node, you can insert the clock and remote maintenance daughter card on the control board. At the same time, a lims card can be optionally provided to provide a lan interface. The main types of interface boards provided by the system are: 8-port / 24-port voice mailbox board (also a computer operator), 8-port / 24-port analog & digital user board, dect base station interface board, 8-port s0 board, stmi2 ip gateway interface board, 2m digital interface board and analog relay board, others include power-down transfer interface board, access control interface unit, etc.
