USB Audio Kit

Operation of the i2050 Software Phone requires the use of the Nortel USB Audio Kit.

The USB Audio Kit provides a high quality predictable audio interface that is highly optimized for

telephony applications. The USB Audio kit allows the i2050 Software Phone to have an absolute

and predictable loss and level plan implementation, which is necessary to meet TIA-810, FCC part

68 and its international equivalents as well as the ADA requirements for the hearing impaired.

With the USB Audio kit, the i2050 can achieve performance rivaling or surpassing that of

hardware telephones.

The USB Audio Kit is fully-compliant with version 1.1 of the USB Device Specification and

Windows Plug & Play specifications. It is fully compatible with the suspend and resume functions

for effective use in battery operated laptops. It is functional on Windows 2000 Professional,

Windows 98, Windows 98 Second Edition, Windows Millennium and Windows XP. No drivers or

software are required for installation.
