16 E1 modular type Framed/Unframed, FXS/FXO/EM2-4/V35/V.24/RS232/422/385 TDM over IP multiplexer
16 E1 modular type Framed/Unframed, FXS/FXO/EM2-4/V35/V.24/RS232/422/385 TDM over IP multiplexer TDM Over IP Equipment Series Interface Converters AD-Net Selangor, Malaysia, Kuala Lumpur (KL), Petaling Jaya (PJ) Supplier, Suppliers, Supply, Supplies | Catacomm Corporation Sdn Bhd


The AN-TDM-IP-16E1-MOD 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 for 4*E1 service card, two 100M Ethernet ports, one 100M Ethernet optical port, and one console management interface.
