Scope

2.1

For the purposes of this standard, the PBX is considered to be a device that performs switching functions between station apparatus interfaces and between the station apparatus interfaces on one side and central office (CO) and special trunk interfaces on the other. Figure 1 shows two types of central of fice interfaces: communication interfaces that transmit and receive network supervisory and communication signals, and specialized interfaces, such as messge registration and AIOD, which are used for allocating billing to outgoing calls. The interface on the station side is assumed to be compatible with the parameters specified in CAN/CSA-T510, Performance and Compatibility Requirements for Telephone Sets (Ref A2) and EIA- 478, Multi-Line Key Telephone Systems for Voiceband Applications (Ref A3). The requirements in this standard are intended to assure satisfactory user voicegrade services in a high percentage of installations both initially and over some period o f time as the network grows and changes occur in telephone serving equipment.

2.2

Compliance with this standard is determined at the PBX interface bo undaries (Fig 1) and is not to be construed as a constraint on the internal coding or switching techniques of the PBX. It is recognized that a PBX using some digital encoding, digital switching, analog modulation, and analog switching techniques will not meet some of the voiceband transmission requirements in Section 4.8 of this standard. However, maintenance of the overall quality of telecommunication performance requires that each connection through a PBX meets the cate gory of transmission requirements specified in this standard with respect to the type of connection and to the PBX coding and switching technique employed.

2.3

The standard recognizes that no one PBX design or installation need be equipped with all types of interfaces contained herein. A PBX complies with this standard when it conforms to the requirements applicable to the interfaces with which it is equipped. For satisfactory service, a PBX should be capable, through the proper selection of equipment options, of satisfying the requirements applicable to its serving area. The requirements for the individual types of PBX interfaces vary between telephone companies and in some cases between central office switching machines; therefore, in some cases multiple options are stated for satisfying a particular requirement.

2.4

The criteria for supervisory and address signals sent toward the network assume that the PBX repeats or regenerates station apparatus dc signals received from the station apparatus. It is assumed that voiceband transmission from one port to a similar or different port of the PBX introduces some small amount of degradation commensurate with satisfactory overall user and end-to-end performance.

2.5

This Standard is intended to be in conformance with the requirements of CS-03, Standard for Terminal Equipment, Systems, Network Protection Devices, Connection Arrangements and Hearing Aids C ompatibility, issued by Communications Canada and mandated by various levels of Canadian regulatory authorities. However, the requirements in this Standard are not limited to those of CS-03. Where the requirements of Standard CS-03 are more stringent than those of this Standard, the requirements of Standard CS-03 shall take precedence.

2.6

It is recognized that some PBX products may not be accommodated by this standard because of nonstandard line interfaces; i.e., other than that described in 4.5. In such systems, the station apparatus must be considered as a whole with the PBX and its associated station wiring, and the overall system must be described in terms of an acoustic (user) to an electrical (network) standard.

2.7

The requirements in this document assume a ringer equivalence number (REN) of 5. If the PBX has a REN of less than 5, then the requirements designated by the parenthetical expression (REN) need to be appropriately scaled in accordance w ith Section 68.312 of the FCC Rules and Regulations. The ringer equivalence number (REN) as used in this Standard is similar to the Load Number (LN) as used in CS-03. Where a parameter in this St andard has ""(REN)"" appended to it, the value shall be appropriately scaled according to the LN determined for a particular trunk interface as specified in CS-03 Section 1. To scale a particular parameter value, the value shall be multiplied by the quotient (100/LN) for impedance parameters and by (LN/100) for dc current parameters, where LN is the Load Number as specified in CS-03.

2.8

In addition to the requirements in this standard, the safety requirements in CSA C22.2 No. 0.7 or No. 225, as applicable (Ref A17), apply. The CSA C22.2 No. 0.7 or No. 225 may be more restrictive. Environmental considerations for PBXs a re found in Ref A5.

This Standard includes Amendments.

]]>
This Standard specifies requirements for the design of the user interface in interactive voice response (IVR) telephone systems where the user input to the system is signalled by dual tone multi frequency (DTMF) tones.

Scope

This Standard specifies requirements for the design of the user interface in Interactive Voice Response (IVR) systems where the user input to the system is signalled by DTMF tones.
NOTES:
1 The committee responsible for this Standard has commenced work on the preparation of a separate standard for IVR systems–user interface, where the user input is by means of human speech.
2 While this Standard does not incorporate requirements for IVR systems where the user interacts with the IVR using a TTY device and not a telephone, it is recommended that organizations commissioning IVR systems give consideration to enabling their IVR systems to be accessed directly via a TTY device. Users of this Standard who are installing IVR systems are also urged to take into consideration that IVR systems are accessed by some users via a telephone relay service operator who will need to listen to prompts and then type the prompts to the user and obtain responses by the same means prior to making a selection or entering data. The ability to pause the IVR would be of significant assistance to the relay operator in these circumstances and it is recommended that such a facility is included.
The IVR system output is presented as audible signals or voice (whether live, recorded, digitized or synthesized) carried over an interactive telecommunications medium (whether public or private or a combination of both, or whether wired or wireless) including the PSTN or ISDN.
This Standard does not cover application, processing and service content.

Specifies requirements for the design of the user interface in Interactive Voice Response (IVR) systems where the primary user input is by speech.

Scope

This Standard specifies requirements for the design of the user interface in Interactive Voice Response (IVR) systems where the primary user input is by speech.
User input by Short Message Service, Wireless Application Protocol and General Packet Radio Service is outside the scope of this document.
NOTE: Where the user interface allows input by means of both DTMF and speech, the requirements of AS/NZS 4263 should apply to DTMF input except where this Standard includes specific requirements for multi-mode input.
While this Standard does not specifically address issues concerned with accessibility by people with disabilities, attention is drawn to the Australian Disability Discrimination Act 1992 which makes it unlawful for a person or organization who provides IVR services, to discriminate against another person on the grounds of the other person’s disability.
Of importance is that any service accessible by the public should be able to be accessed without discrimination unless making the service available would impose unjustifiable hardship on the person or organization providing the service, would be technically impossible, would impose major difficulties or involve unreasonable costs.

This document applies to segmentation filters in a mains communication system intended for utility networks or household and similar fixed installation including residential, commercial and light industrial buildings. These filters are used to control the coupling of signals between two areas of a mains communication system, as illustrated in Figure 1. This document defines in the relevant frequency range: – the minimum impedance at both ports of the filter, – the minimum attenuation of signals transmitted between the ports of the filter.
