Bitstream NGA and VULA Bitstream NGA and VULA

  • Is it possible to subscribe the Bitstream NGA and VULA services at the same time ?
  • It is possible by signing the two dedicated contracts. Of course, for services delivery, it is also needed to connect to TIM network the way each service requires (Exchange node with OLT for the VULA service, specific connection node for the Bitstream NGA service).

  • Under which conditions is it possible to deliver the Bitstream NGA and the Bitstream Ethernet services together on the same delivery kit ?
  • Delivery of the 2 services together on the same delivery kit is possible only provided that:

    • The OLO wishing to deliver both of them on the same kit has subscribed both of them. It is not needed to adhere to both the offers at the same time: if an OLO has subscribed only one of them and is currently getting the associated service, it will always have the option to adhere to the other one later on, and consequently start the delivery of both the service on the same delivery kit, provided of course that also the 2 following conditions are verified.
    • The L2 device used for the delivery kit is suitable for the delivery of the Bitstream NGA service (at present all the devices are good except for the Cisco 3750).
    • The delivery kit is connected to a node of the TIM network that is suitable for the delivery of the Bitstream NGA service.

    Note that the delivery of the 2 services together on the same delivery kit only allows to share the end device and the associated local/geographical connections between the 2 services, but does not allow to share the backhaul bandwidth and VLANs, that instead remains independent for both of them. So, backhaul bandwidths and VLANs for the 2 services must be requested and sized independently for each one.

  • Is it possible to deliver the Bitstream ATM and the Bitstream NGA services on the same delivery kit ?
  • It is not possible.

  • Is it possible to deliver the Bitstream NGA and/or the Bitstream Ethernet service on a VULA delivery kit ?
  • It is not possible. The VULA delivery kit can only be used to deliver the VULA service.

  • Can the VULA delivery kit be shared among different OLOs ?
  • No, it cannot. Any OLO must request VULA delivery on a desired suitable exchange node independently from all the other OLOs. If other OLOs are getting VULA on the same exchange node, any new delivery kit for further OLOs will be connected to the same VULA delivery switch installed by TIM, but service delivery will be independent for any connected OLO.

  • How do you read the file “Punti di Interconnessione per Bitstream NGA” (it is the file listing all the nodes of TIM network that are available for the delivery of the Bitstream NGA service)?
  • The file “Punti di Interconnessione per Bitstream NGA” is mainly the same as the file “Punti di Interconnessione previsti per Bitstream su piattaforma Ethernet” (that is the listing all the nodes of TIM network that are available for the delivery of the Bitstream Ethernet service), and it is important to point out that all the nodes listed therein are always suitable for the delivery of the Bitstream Ethernet service.

    So, the available nodes for the delivery of the Bitstream NGA service are a subset of the currently available nodes for the delivery of the Bitstream Ethernet service: the former nodes are therefore the only available nodes for the delivery of both the services together.

  • Which are the available nodes for the delivery of the VULA service ?
  • The delivery of the VULA service can be requested for any exchange node (active and/or planned) where an OLT at least is located: such exchange nodes are listed (resp.) in the “Centrali NGA attive (pianificate)” files. Briefly, the available nodes for the delivery of the VULA service are all the published TIM exchange nodes where an OLT at least is located.

  • What is a “naked” FTTCab line ?
  • A “naked” FTTCab line is a FTTCab line without a PSTN/WLR service. So, it is a line where only the VDSL2 data connectivity is provided. FTTCab lines can be requested both in “naked” mode and in “shared” mode, the latter being the presence of a PSTN/WLR service together with data connectivity.

  • What is a “shared” FTTCab line ?
  • A ”shared” FTTCab line is a line with both a POTS/WLR service (provided by TIM through its phone network) and a VDSL2 data connectivity service provided through the Bitstream NGA or VULA service.

  • Is it possible to activate VDSL2 data connectivity over an ISDN line ?
  • It is not possible. In other words, it is not possible to have a “shared” FTTCab line with an ISDN service. In this case, the delivery of the data connectivity service requires the activation of a dedicated “naked” FTTCab line.

  • Is it possible to activate a FTTH line with a PSTN/WLR service (i.e. a “shared” FTTH line) ?
  • It is not possible. FTTH lines can be requested only in “naked” mode.
