Digital Programmed Exchange Machine Application Solution

The HJ-E800 series digital program-controlled switches offer three remote module access methods: fiber optics, 2M, and Ethernet. Fiber optics is used for bare fiber resources and can provide a 100M Ethernet for data transmission channels.

2M interfaces utilize the redundant 2M resources from SDH or PDH systems.

Ethernet access is a relatively innovative remote module expansion method for our company, suitable for remote modules without fiber optics or 2M resources. It can extend IADs and connect to SIP-based phone networks. It is applicable for remote number portability, for floors or enterprises, and can also be used for digital gateway networking. The HJ-E800 offers a red alarm function, making it ideal for hotels, enterprises, and other high-fire-safety requirement environments.
