Product Overview
The TDMoverIP integrated multiplexing device features a desktop form factor and can be configured with 1 to 8 analog subscriber ports (FXS), analog trunk ports (FXO), and magnetic‑loop trunks (MAG). It allows flexible, step‑by‑step configuration of FXS, FXO, and MAG ratios in increments of eight, while supporting multiple protocols. Its robust hardware design ensures stable performance even under full load, delivering high‑quality voice calls. Rigorous, comprehensive testing is conducted during production to guarantee consistent quality and reliable operation. It enables network‑based telephony for carriers, PBX systems, any analog telephone, and multi‑site enterprises such as international trade firms, schools, and chain stores.
Product Features
1. Provides both a console (CLI) and a web-based management interface for easy installation and deployment.
2. The network interface provides two 100-Mbps Ethernet electrical ports and one 100-Mbps Ethernet optical SFP port.
3. Each of the 8 voice ports supports optional FXO, FXS, E&M two‑wire or four‑wire audio interfaces, as well as magnetic‑switch telephone interfaces.
4. Supports voice FXO/FXS interfaces, with features including caller ID, reverse‑polarity billing, and fax functionality.
5. Supports comprehensive fault detection and network management alarm functions.
6. Low power consumption and high integration. The voice interface complies with Level 3 lightning protection standards.
7. Supports overcurrent and overvoltage protection for the POTS telephone interface.
8. Metrics such as transmission loss, loss frequency, nonlinear distortion, crosstalk attenuation, lateral crosstalk noise, and non‑lateral crosstalk noise all meet carrier‑grade standards.
9. Supports administrator login and password protection, features a built-in firewall to effectively guard against various network-based malware attacks, and enhances data security.
10. Rich protocol support, with SIP protocol compatibility.
11. Supports RTP/RTCP protocols, enabling real-time voice packet encapsulation and playback, with comprehensive service‑support capabilities.
12. Robust QoS guarantees, supporting IPv4 ToS and DiffServ services to ensure voice priority.
