Introduction This revision of ANSI/TIA/EIA-810-A establishes handset, headset and

44、 handsfree telephone audio performance requirements for digital telephones regardless of protocol or digital format. A number of improvements and corrections have been made, particularly related to the use of ear simulators. This standard addresses conventional narrowband performance, where narrowba

45、nd is defined as the frequency range between 300 and 3400 Hz. Requirements for wideband telephony, in the frequency range between 150 and 6800 Hz are defined in TIA-920. ANSI/TIA-810-B 2 2. Scope This standard establishes voice performance requirements for narrowband digital telephones and devices.

46、Transmission may be over any digital interface including wired, or wireless, Local or Wide Area Networks, Firewire/IEEE Std 1394, Universal Serial Bus (USB), public ISDN or digital over twisted pair wire. This includes TDM-based and packet-based (e.g. VoIP) telephones. These telephones may be connec

47、ted through modems, Voice Gateways, wireless access points, PBXs, or personal computer-based telephones. Examples include: ISDN telephones, digital proprietary telephones, VoIP telephones (corded and cordless), softphones (such as laptop computers), IEEE 802.11 telephones, USB telephones, USB device

48、s, DECT telephones, BluetoothTelephones and Bluetooth devices. In principle, this document can be used to evaluate wireless devices and other devices where the A-law and mu-law codecs are not supported for the full audio channel. In this case the targets specified in this standard may not apply. If

49、A-law or mu-law codecs are supported they shall be used for testing to compliance to this standard. For telephone systems that incorporate a Universal Serial Bus (USB) type interface or a Bluetooth type interface to a host (such as laptop computers), it may be desirable for the USB or Bluetooth device to meet the requirements of relevant clauses of this standard, where the host device is assumed to have a 0 dB loss plan, in its default state. It may be desirable for the device to provide gain adjustment for both the send and receive channels. When connected to a
