SCOPE This standard establishes cordless telephone performance requirements and measurement procedures for evaluating features and operational attributes generally not included in telephones with a cord
36、ed handset. It is the goal of this document to standardize features and operational attributes that will increase the telephone users overall satisfaction without preventing product differentiation, or competitive advantage, between products. 2. INFORMATIVE REFERENCES The following standards contain
37、 provisions, which, through reference in this text, constitute provisions of this Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this Standard are encouraged to investigate the possibility of applying
38、 the most recent editions of the standards indicated below. ANSI and TIA maintain registers of currently valid national standards published by them.

ABBREVIATIONS AND ACRONYMS For the purposes of this Standard, the following abbreviations and acronyms apply. 1. CPE Customer Premises Equipment 2. OSI Open Switch Interval 3. RF Radio Frequency
40、4. VMWI Visual Message Waiting Indicator 3.2. DEFINITIONS For the purposes of this Standard, the following definitions apply. Active State The CPE is off-hook and the handset Voice-Path is active. Basic Functionality CPEs ability to perform Send, Receive, Dialing, Alerting, etc. Line Idle A state of
41、 the telephone line when all connected CPE are on-hook. Line In-Use A state of the telephone line when at least one CPE is off-hook. Line State The condition of the Tip and Ring interface. It can be either In-Use or Idle. Listening-Path The path of electrical signals at Tip and Ring to acoustic sign
42、als at the CPE receiver/speaker. Off-Hook The state of the CPE when the hook-switch is closed. This refers to the state of a particular CPE rather than the line state. On-Hook The state of the CPE when the hook-switch is open. This refers to the state of a particular CPE rather than the line state.
43、ON Key General term for any button that allows the handset to place the CPE in the off-hook state. OFF Key General term for any button that allows the handset to place the CPE in the on-hook state. OSI The temporary removal of dc battery voltage between Tip and Ring for a duration of 10 ms to 350 ms
44、. Standby State The CPE is on-hook and the handset is not on the charger. No features (e.g. intercom) or modes (e.g. call log review) are active in the Standby State. Talking-Path The path of acoustic signals at the CPE microphone to electrical signals at Tip and Ring. Timed Disconnect Signal A DC s
45、ignal generated by the network interface equipment characterized by removal of the dc voltage between Tip and Ring for a duration of 600 ms to 1000 ms. Voice-Path A path that collectively consists of a Talking-Path and a Listening-Path. TIA-470.320-C 3 4. REQUIREMENTS 4.1. CATEGORIES OF CRITERIA Thr
46、ee types of requirements are specified in this standard; Mandatory, Recommended, and Permissive: 1. Mandatory requirements are designated by the terms “shall” and “shall not”. These requirements are used to indicate conformity in which no deviation is permitted. 2. Recommended requirements are desig
47、nated by the terms “should” and “should not”. These requirements generally relate to compatibility or performance advantages towards which future designs should strive. 3. Permissive requirements are designated by the terms “may” and “may not”. These requirements are used to indicate an action that
48、is permitted within the limits of the standard. 4.2. GENERAL DC FEED TEST CIRCUIT R1CLLR1C50 VdcR2Load or SignalGeneratorTRNOTES: 1. C = 50 uF with pair having matched values within 1%. 2. L = 5 H with pair having matched values within 20%. 3. R = 200 ohms (including resistance of L) with pair havin
49、g matched values within 1%. 4. V = 50 Vdc +/- 2 Vdc. This is a simplified DC feed circuit. It does not implement the current limit characteristic of modern end offices, which typically limit the maximum current supplied by the office.
