USB Audio Kit

Operation of the IP Softphone 2050 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 IP Softphone 2050 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 IP Softphone 2050 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
