GAO Software Replaces Modem, Fax, Telephony Chipsets

At present, there are many mature, but still highly successful systems need upgrades or even redesigns. However it is often challenging for design engineers to find suitable modem and fax chipsets. Many chipsets are harder to get due to ever reduction in their production volume. There are no inventory for many still highly useful legacy chipsets.

On the other hand, the computing power of embedded processors are so powerful now that it is very economical to implement soft modem and fax.

As a result, GAO’s modem, fax, and telephony software is in demand to replace both in-production and legacy modem, fax and telephony chipsets.

Customers have used our software to replace in-production as well as legacy and EOL (End of Life) modem/fax chipsets and communications devices from a diversified range of vendors such as Conexant, TI, TDK, Motorola, Ess, Broadcom, Cisco, Siemens, Infineon, Alcatel, Multitech, Huawei, AT&T, Analog Devices, Nortel. If you want to replace a such chipset, please feel free to contact us.
