While filing for the Telecommunication Engineering Centre TEC Certification with the Department of Telecommunications, the applicant must mention the associated model he wants to incorporate into its business operations post-TEC registration. Here in this article, we have discussed some of the associated models for TEC certificate registration.
Why choose a Pizza Box Model post-TEC certification?
In such equipment, the business uses a single PCB or motherboard generally to treat several models. For example, suppose a Pizza Box Model built around a particular motherboard with the most extensive configurationis tested and certified, then the businesses must cover all other models built around the same motherboard with a lower configuration by the same Certificate. This model is widespread for TEC registration. Many pieces of equipment generally fall under this Pizza Box model.
Chases-based Model for Similar Backplane
Such equipment generally consists of a single chassis with the same backplane. Common function cards like processor or logic cards, power supply cards, and other standard control cards are in the Chassis. The Businesses form different hardware variant models by inserting various available cards (like frequency filter cards or interface cards) in the Chassis.
Multiple Chassis under one Certificate
If one model built on one Chassis is tested and certified, the applicant must cover all other models build around the same Chassis . Therefore, the businesses can include a maximum of 10 associated models (series models) in one application for TEC registration.

Why choose one model over the other?
People are generally confused between chases-based and pizza-based models. The main difference is that Pizza based model is based on a single PCB or motherboard. In contrast, chases-based models have a common backplane with the same processor or power supply. Tghe applicant can insert or delete a variety of cards as per requirements. Many who seek TEC certificates for server-type devices fall under Chases based model.
Family-based Model: Multipurpose Business Model for TEC Certification
The applicant can insert such equipment families consist of several chases with varying capacities interchangeably in any other chases. Depending upon customer requirements, the TEC applicant can use different combinations of chases from the family and different combinations of cards at one site, called one model.
Chases in a Family Model
If the TEC applicant tests and certifies all chases of the family separately or collectively, then he must test and certify all cards in the family by inserting them into whatsoever Chassis. The same Certificate must cover all other models built by selecting some chases and cards. Telecom equipment such as telephones and routers come under these categories for TEC certificate registration.
TEC Certification: Split Unit Type Model
Such equipment consists of two functionally independent units, an indoor and an outdoor unit, a baseband unit, and a radio unit. Individual unit safety and EMI/EMC testing are possible in isolation. But the applicant must carry out the technical parameter testing out only when they casn connect the two units.
Types of Units in a Split Model
Each of the two units is often in different varieties;
- Primarily, the outdoor or radio unit variety is based on the frequency of operation and power capability
- Indoor or baseband unit variety is based on chassis size, interface cards, etc.
Suppose all the outdoor or radio units have been individually tested. In that case, the Authority will treat the collection of such units and all outdoor or radio units as a family and certified accordingly. Further, the concept of the associated model may be applied to indoor or baseband units if these meet the criteria for TEC certificate registration.
