Standard

A Standard is a document that applies collectively to codes, specifications, recommended practices, classification, test methods and guides, which have been prepared by an organization or group after due consultation and published in accordance with established procedures. Most important advantages/needs of using TEC Standards, with regard to telecom equipment/network/services, are to:

• Ensure quality and reliability
• Comply with regulatory requirements & Improve market acceptance
• Ensure system interoperability & facilitate interchangeability of parts
• Comply with customer requirements & ensure safety of user
• Achieve economies in purchase of equipment

The TEC Standard documents are as follows:

The details of TEC Standards are as follows:

Standard for Generic Requirements for a Product/ Equipment

The Standard for Generic Requirements for a Product/Equipment (erstwhile Generic Requirements (GR)) for a telecom network element or a set of network elements, lays down its requirements for the product/equipment to work seamlessly in Indian Telecom Network. These requirements refer to the following:

• Interconnectivity and interoperability requirements
• Quality requirements
• EMI/EMC requirements
• Safety requirements
• Security requirements
• Any other equipment requirements that are considered generic
• Desirable requirements, if any

Type Approval Certificate (TAC) is issued for conformance testing against the clauses of Standard for Generic Requirements for a Product/Equipment.

Standard for Interface Requirements for a Product/ Equipment

The Standard for Interface Requirements for a Product/Equipment (erstwhile Interface Requirements (IR)) refers to the requirements of an interface between two network elements at different layers of protocol stacks as applicable. Interfaces are defined at different layers for convenience of peer-to-peer communication:

• Layer 1 Physical (Cable, RJ-45, E1 etc.)
• Layer 2 Link (MAC, Switches, PPP etc.)
• Layer 3 Network (IP, Q. 931 etc.)
• Layer 4 Transport (TCP, UDP, etc.)
• Layer 5 Sessions (Call setup, teardown, syn, ack, duplex/simplex operation etc.)
• Layer 6 Presentation (Encryption, ASCII, MPEG etc.)
• Layer 7 Application (SNMP, HTTP, FTP, WebSocket etc.)

Interface Approval Certificate (IAC) is issued for conformance testing against the clauses of Standard for Interface Requirement for a Product/Equipment.

Standard for Service Requirements

The Standard for Service Requirements (erstwhile Service Requirements (SR)) details the services and network related requirements for specific applications, which should be met by service providers in accordance with the requirements specified by the Licensing Authority.

Standard Document of TEC

The Standard Document of TEC refers to a set of standard/common requirements or specifications inter-alia, in respect of protocols, numbering, routing, switching, safety, security, EMI/EMC, environmental related requirements etc. issued by TEC for the equipment or product or network. It can be used either independently or can be referred to in Generic Requirements/Interface Requirements/Service Requirements of the telecom products/services.

TEC Test Guide

The Test Guide of TEC (erstwhile Test Schedule and Test Procedure (TSTP)) is associated with erstwhile Specifications i.e GRs/IRs/SRs. Test Guide involves testing and measurements to be performed as per Standard for Generic Requirements of a Product/Equipment, Standard for Interface Requirements of a Product/Equipment and Standard for Service requirements.

In view of the multi-functionality of the equipment with the advancement of technology, the testing method/procedure may broadly specify the expected/specified outcomes without insistence / adherence to particular testing equipment.
