Modular type TDM over IP

View : 234
Type : E1/v.35/v.24 over IP
Description :

The TDMoverIP device is mainly used to provide 4 service card slots on the IP network. It can be inserted into the E1 module (4 E1 interfaces)

Overview

    The TDMoverIP device is mainly used to provide 4 service card slots on the IP network. It can be inserted into the E1 module (4 E1 interfaces), voice module (4/8/16 FOX/FXS interface), V.35 module (2 channels). V.35 interface), serial interface module (4-ch RS232/422/485 interface); maximum capacity can be filled in 4 slots. Enables operators and enterprises to seamlessly and reliably connect TDM devices and user Ethernet on a standard low-cost wireless or wired Ethernet/IP fabric with no impact on voice quality. TDM over IP is transparent to TDM signals, ensuring that any device with a physical E1 interface is seamlessly connected, such as PBX, mobile base stations, SS7 signaling devices and voice mail systems. Can be used in IP-based communication systems such as LAN, WAN, MAN, and wireless networks.
    It is with 4 slot service card, two 100/1000M Ethernet ports, one 100/1000M Ethernet optical port, and one
console management interface.
