Product Overview
The TDMoverIP integrated multiplexing device is rack‑mountable and can be configured with 1 to 30 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 30, supporting multiple protocols. Its robust hardware design ensures stable performance even under full load, delivering high‑quality voice calls. Rigorous, comprehensive testing during production guarantees consistent quality and reliable operation. It enables network‑based connectivity for carrier‑grade telephones, PBX‑connected phones, 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 management interface for easy installation and activation.
2. The network interface provides two Gigabit Ethernet electrical ports and one Gigabit Ethernet optical SFP port.
3. Each of the 30 voice ports supports optional FXO, FXS, E&M two‑wire or four‑wire audio interfaces, as well as magnetic‑switch telephone interfaces.
4. Voice FXO/FXS interface, supporting 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 defend 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 prioritization.
