Collection termination and transit on the TIM fixed telephony network
Who can use the service?
This is the TIM "wholesale" service, available throughout Italy, for Operators who wish to offer fixed voice telephony services to their end customers, connected to their network and/or to the TIM network, thus enabling them to make and receive calls to/from TIM a customers and/or those of other Operators.
Description of the service
After interconnecting to the TIM network, Operators can make use of a series of services that permit their customers to:
TIM offers two different technologies to Operators for interconnection with its fixed telephony network:

Interconnection at SGT level excludes interconnection at BBN level, and vice versa. The interconnect mode chosen by the Operator, either BBN or SGT, is applied univocally at national level.
During the course of 2011, TIM began work to introduce a new network architecture and platform, which, using interconnection by VoIP/IP technology, permits supply of “basic” telephony services, in an “alternative” mode to the existing TDM/ISUP interconnection.
The new model envisages that telephone interconnection using VoIP/IP technology will be created on Network to Network Interface (NNI) with SIP or SIP-I protocol, through the edge network level of IP routers located in TIM's OPB (Optical Packet Backbone) network nodes.
From each interconnect point chosen (TDM or VoIP), Operators can make use of the following services:

In order to use the services described above, Operators must first request:

Inter-district collection, termination and transit services using both TDM and VoIP/IP technology are “deregulated” pursuant to the AGCom Resolutions 179/10/CONS and 180/10/CONS and, therefore, are no longer part of the above Reference Offers.
