Copper Access

LLU Service

LLU service enables the last mile connectivity between a service provider and their end subscribers using OTE copper network. 

By installing their equipment inside or near OTE’s Local Exchanges, Telcos gain access to their subscribers’ copper lines. Thereby, Telcos get the opportunity to offer diversified services and support in the realization of their business plan.

LLU service has served as means of development for both fixed and broadband access. By placing their equipmnent in OTE Local Exchanges, Telcos utilized LLU as a key component to develop their customer base, in direct collaboration with OTE Wholesale.

LLU service showed expeditious growth during 2006 – 2015, which reflects the wholesale market development in Greece.

Given the fact that Telcos still reach their end customers via local loops, LLU service is continuously evolving to include new process flows, in order to further meet the needs of wholesale market. 

In that context, Telcos enjoy more simple and agile procedures regarding service delivery and optimum fault management, being sure that copper technical capabilities are fully exploited as a means of providing telephony and broadband services.

Always in line with the regulatory authority, some of the specialized services recently developed: 

  • Low synchronization fault management
  • Automated flow for Telcos’ queries and respective feedback
  • New technical methods on fault detection (TDR measurements)
  • New functionalities supporting better cooperation between different technician groups


At the same time, obsolete wholesale services that are no longer relevant to market needs are being terminated (eg shared loop, combined loop & portability requests, etc). What is more, maintenance tasks are taking place, so that LLU service remains a pillar of broadband growth across the board.


Through LLU service a wide range of benefits is provided:

  • Access to more than 4 million access lines
  • Nationwide coverage in more than 2000 Local Exchanges, all around Greece
  • Maintenance & fault repair by OTE’s high skilled personnel
  • High level of availability & service management
