Overview:
The IDM-30EN Integrated Service Multiplexer uses optical fiber as the transmission medium, utilizing standard optical fiber or E1 transmission channels (G.703 standard), adopting the PCM30/32 format to convert telephone service signals or data signals to be transmitted into optical signals for transmission over fiber to the remote end. In addition, compared with the IDM-30E Integrated Service Access Device, it differs in that it can provide not only all the services offered by the former but also two channels of Ethernet services.
This series of equipment features easy installation, simple operation and maintenance, and high system reliability. It can be widely applied in public telephone network access or dedicated line information transmission in industries such as telecommunications, electric power, banking, and public security.
Main Features:
- Adopts a 19-inch 1U standard chassis for easy installation.
- Provides 30 channels of standard data services;
- Clock modes: master clock and user clock can be configured to meet various application environments;
- Rich 64K user interfaces: provides ordinary telephone cards with Caller ID display (FXO, FXS);
- 4 groups of E1 interfaces support transparent transmission mode;
- 2 groups of wire-speed 100M Ethernet interfaces with VLAN partitioning support, and the Ethernet can be configured as 4 groups;
- Equipped with comprehensive function control switches and alarm indication features;
