- Are non-standard fees envisaged? If so, which cost components are charged to the Operator?
- Which resilience (protection/restoration) mechanisms are available?
- Which types of Client interface are supported with the service?
- What are the latency values for a connection (e.g. 10 GbE Rome - Milan)?
- Is it possible to guarantee the “transparency” of the carried Client signal?
- Can the service be delivered to the Customer's premises on two separate devices?
- Is it possible for diversified unprotected or protected 1+1 diversified two way connections to “get onto” the TIM transport network on two distinct exchanges?
All costs are set out in the offer after the feasibility study, and there may be extra costs deriving from the particular system configuration that meets the customer’s requirements (e.g. optic fibre double drop, double device at the customer's premises...)
A connection may be requested in one of the following modes:
- One way connection => single connection
- Two way connection unprotected diversified => two distinct connections that have the same end points, each of which has its own identification (in commercial terms the two connections are considered as one entity and not independent from each other).
- Protected 1+1 diversified => There is a single connection but it is set up with two channels (one working and one back-up), the customer is provided with a single interface on a transponder with a double optic line which handles an automatic exchange on the backup channel, if a problem is detected on the working channel.I
It is also specified that: The backup protections (therefore connection type 3. Protected 1+1 diversified) cannot always be achieved technically and sometimes an ad hoc design is necessary and a feasibility study to check whether it is possible to achieve the Customer's requests and to define the timing and costs of the relative set up. The term “diversified” means that, where technically possible, without extra costs, a route diversification for the two channels and an electronic diversification will always be set up, understood as board diversification in cases where the two channels cross the same device of the Transmission network. If route diversification is not possible, electronic diversification will in any case be guaranteed. Particular diversification needs associated with the specific type of connection (e.g. dual drop, dual homing), or diversification needs with respect to existing connections, must be requested with as much detail as possible and will always be subject to a technical and economic feasibility analysis.

- The latency values (rating plate data) can be estimated after the feasibility study using the following formula: 0.0056 ms per Km, considering negligible the time it takes to cross the devices. For example, for a Rome Milan connection of 860 km of fibre the expected one way latency is 4.8 ms.
- In the case of particular latency requirements, these requirements can be displayed in the connection request so that the maximum latency allowed can be used as a project constraint.
Yes, it is possible to guarantee the “transparency” of the carried Client signal by installing an x-WDM transponder device at the termination.
Yes, it is possible to deliver the service to the Customer's premises on two separate devices based on a project and with additional fees charged to the Operator (“device diversification” option). In the presence of two queues this option is applied to both queues, unless the Customer specifically requests otherwise.
This configuration can be requested with the “dual homing” option. Where there are two queues the option should be understood to be applied symmetrically to both queues, unless the customer indicates otherwise. The timing and costs to implement the solution requested may only be known after the feasibility study.
