Digium TE435

The Digium TE435 4-port board supports 96 (T1/J1) or 120 (E1) simultaneous calls without echo cancellation. The board is designed for Asterisk and provides the user with exceptional digital communication quality.

Digium TE435 boards are a new line of boards for 4 E1 streams. Unlike the previous generation, the boards have a height of 2 units, the problem with jitter that appeared when using some models of motherboards has been eliminated, and the boards are equipped with lightning protection. The TE435 board operates in T1/E1/J1 modes, which is determined by a switch (jumper), while each port can operate in its own mode, which makes it possible to use the Digium TE435 card as a translator between equipment of different types, and also makes it possible to connect inexpensive channel banks for connecting analog communication lines of medium and high density. The Digium TE435 board for 4 ports supports 96 (T1 / J1) or 120 (E1) simultaneous calls without echo cancellation. The Digium TE435 board is compatible with existing software and hardware, and fully integrates with the Asterisk IP-PBX/IVR platform for IP telephony (VoIP). Using PCI bus mastering technology allows you to reduce the load on the central processor and increase the productivity of the input-output subsystem, and also allows you to increase the density of board placement in the PBX. Digium TE435 supports industrial telephony and data transmission standards such as ISDN PRI (American & Standard Euro), PPP, Cisco, HDLC, Frame Relay with the ability to work both as end equipment (TE) and as a network terminal (NT).
