The IAD1280 interconnects with the SoftCo through the standard SIP protocols and provides 280 FXS interfaces.

Product Positioning

As a terminal device at the edge access layer of HUAWEI unified communications, the IAD1280 is widely used on the unified communications network. By adopting the standard voice codec and compression techniques, the IAD1280 encodes voice signals, encapsulates them into IP packets, and then sends the IP packets to a specified media gateway through the IP network. After the IP packets reach the destination, the destination IAD performs the reverse processing to restore the packets into voice signals. In this way, the VoIP and FoIP functions are achieved.

The IAD1280 is applicable to middle-density areas such as enterprises and residential communities. The IAD1280 has 7 ASU boards. Each ASU board connects to up to 40 POTS.
