The relationship between cat pools and traditional telephone lines

In traditional telephone communication, modem is the bridge between telephone line and computer communication. Cat Pool inherits and expands this feature, adapting to the needs of modern communication networks:

From single channel to multi-channel: Traditional modems can only serve one telephone line at a time, while modem pools support multiple lines in parallel through multiple modulation and demodulation modules.
Wireless network support: Cat Pool not only supports wired phone lines, but also can access 3G, 4G, and even 5G networks through SIM cards
