Terminating Circuits Terminating Circuits

  • What do we mean by Terminating Circuit?
  • By Terminating circuit we mean a circuit with a dedicated capacity between a network termination point coinciding with the premises of an end user and a termination point at one of the TIM nodes (DP) enabled to gather Terminating circuits.

    Two different types of Terminating circuits are available (with different technical characteristics and delivery solutions):

    • Analogue Terminating Circuits, PDH, SDH, Ethernet over SDH: “traditional” Terminating  circuits created in analogue technology or via PDH or SDH transport;
    • Ethernet Terminating Circuits on optical fiber: “new generation” circuits, created through Ethernet transport on optical fiber.
  • Which TIM Delivery Points are enabled to gather Terminating circuits?
  • For the “traditional” Terminating circuits there are 561 Regional Transmission Nodes (RTN) to which the Operator can connect to collect Terminating Circuits within the context of the entire RTA (Regional Transmission Area) to which the node belongs; the list of Transmission Nodes is set out in ANNEX 1 of the Reference Offer. 

    For the “new generation” Terminating circuits they are the Delivery Points of the Ethernet network enabled to collect this type of circuit; the list of Ethernet Delivery Points is available on this site (italian version), in the section "I Nostri Servizi" / “Trasporto Dedicato” / “Circuiti Terminating” / “Coperture”.

  • Is there a Database (DB) of the exchanges enabled to collect the Ethernet Terminating circuits on optical fiber?
  • Yes, the “Coverage” section, available on this site (italian version), in the section "I Nostri Servizi" / “Trasporto Dedicato” / “Circuiti Terminating” / “Coperture”, contains a list of the exchanges collected by each DP and the relative range.

  • What are feasibility studies for?
  • The feasibility study is used to verify the availability of the installation resources necessary to realize the service requested and to define its delivery times and costs.

  • When is a feasibility study mandatory?
  • The feasibility study is mandatory in the following cases:

    • traditional” Terminating circuits with a speed of over 2 Mbit/s or significant quantities of 2 Mbit/s circuits at the same premises and/or same line;
    • Ethernet Terminating circuits on optical fiber relating to end user premises belonging to exchange bands between 0 and 3 with “non standard” configurations;
    • Ethernet Terminating circuits on optical fiber relating to end user premises belonging to different exchange bands from 0, 1, 2 and 3.
  • What are the response times for a Feasibility Study?
  • On average TIM responds within 10 calendar days.

  • Are charges made for the feasibility study?
  • Yes, the cost is 260 euros; this cost is not due if the circuit is subsequently ordered by the Operator.

  • What are termination costs?
  • No termination costs are anticipated if terminations occur after the expiry of the minimum contract term (one year after activation). 

  • How can the length of the connection as the crow flies be calculated to determine the price of “traditional” Terminating Circuits?
  • By using the special tools available on the Portal.

  • How can the price of the Ethernet Terminating Circuits be determined?
  • For the configurations described in the Reference Offer, the price depends on the speed range the circuit belongs to (up to 100Mbit/s or greater than 100Mbit/s) and the “Band” (0, 1, 2 and 3) of the connection exchange of the Circuit.

    For Circuits belonging to bands other than 0, 1, 2 and 3 and for non-standard configurations of circuits in bands 0, 1, 2 and 3, the prices are determined each time based on the outcome of the feasibility study (always mandatory).

  • Pursuant to Market 4, is certification by the Operator necessary for the open PoPs?
  • Yes it is.

  • What contracts are necessary in order to be able to use the Terminating service?
  • The signing of a specific contract for each of the two different types of Terminating circuits (Analogue Terminating circuits, PDH, SDH, Ethernet over SDH and Ethernet Terminating circuits on optical fiber) is required.  Furthermore, if the Operator is not co-located in the transmission node(s) (NTR) in which they intend to gather the PDH, SDH, Ethernet over SDH Terminating Circuits, they must sign the new contract for Interconnect Flows at the same time.

  • What is required to access the Ethernet Terminating Service on optical fiber?
  • The requesting Operator must purchase in advance at the Distribution Point a “Kit” dedicated to collecting this type of service.

    Alternatively the Operator can collect the circuits onto a Port of the Multiservice Kit dedicated to the Ethernet Terminating service on optical fiber.

  • Which Classes of Service (CoS) are guaranteed for Ethernet Terminating Circuits on optical fiber?
  • Three Classes of Service are envisaged: CoS 2, 3 and 5.

  • It is possible to extend an Ethernet Terminating circuit on optical fiber on a DP other than that belonging to the connection exchange of the end user's premises?
  • In the case of collecting the circuit onto a dedicated Kit, this is not possible, as the Kit must be connected to the Distribution Point with territorial authority for the connection exchange of the network termination point.

    In the case of collecting the circuit onto a Port of the Multiservice Bitstream Kit dedicated to the Ethernet Terminating Circuits, however, there is the possibility of extending the circuit onto another Distribution Point inside the Collection Macro Area, using the “Backhauling” service.

  • Must collecting the Ethernet Terminating Circuits onto the Multiservice Bitstream Kit always be preceded by configuring the bandwidth aggregation (CAR)?
  • Yes, for collecting the Ethernet Terminating Circuits onto the Multiservice Kit, it is necessary to request the advance configuration of the CAR.
