SubLLU FAQs

What does the term regulated product mean? How does regulation affect Colocation, LLU & SubLLU products?

Regulated products are not affected by the market rules but are subject to specific regulatory framework (Reference Offer), which is introduced by the competent public authority.

Colocation, LLU & SubLLU products are described at the Unbundling Reference Offer (RUO), published by the Hellenic Telecommunications & Posts Committee (Greek NRA).

RUO describes thoroughly all the order and fault management procedures of the main products and their supplementary services.

What is the difference between Colocation service for LLU & Colocation for SubLLU?

The difference between the two services lies at the point where the Telcos install their equipment.

Colocation oriented for LLU service, requires that the provider installs its equipment inside specially formed space situated within OTE Local Exchanges (Physical Colocation Service) or outside of the Local Exchanges (Remote Colocation).

Colocation oriented for SubLLU service on the other hand, requires that the Telco installs its equipment inside own cabinet, at close distance to OTE’s KV.

What is the difference between the LLU & the SubLLU service?

The difference between the two services lies at the demarcation point.

LLU service ends at the OTE’s Local Exchange, while the SubLLU service at the OTE’s KV.

Due to this difference, SubLLU service is fit to provide better service quality, although the provision conditions differ widely between the two access services.
