13 January 2006
Agenda
• Report back from NICC TSG
• MSAN Voice Access Requirements
• Reference Architecture
Report back from NICC TSG
NGN Multi-service Interconnect Documentation• Documentation broken down into a structure that is easy to understand
and will be simple to update
– Layer 1 Top level - defines the scope of Multi-Service Interconnect for UK NGNs, binds related standards at particular versions to an NGN MSI release
– Layer 2 Defines all service agnostic common infrastructure for the NGN MSI.
– Layer 3 Service interconnect specifications, each service will have a separate document
– Layer 4 General Reference ND Documents that are referred to within the main ND layer documents for service specific or common infrastructure implementations.

MSAN Voice Access Requirements
MSAN Voice Access Requirements
• The intention is to agree these now to enable them to be passed to the TSG/ARS meeting on the 17th January
• As previously agreed, Consult 21 will not define the solution, just the requirements
MSAN Voice Access Requirements
• 1. The architecture must provide the ability to provide Operator A with control of Operator B’s MSAN lines.
• The capability must be provided via an interconnect defined by NICC
• 2. All PSTN Emulation features shall be capable of being provided to Operator A.
• 4. What QoS will be available to Operator A?
• 5. The architecture shall support an automatic mechanism to prevent overload at the point of interconnect. Including but not limited to:
• Signalling transport
• Session processing
• Bearer control mechanisms
• 6. The bearer media stream shall support voiceband data and DTMF. Support for RFC2833 (DTMF out-of-band transport) and T.38 (Fax/modem out-of-band transport) is not required.
• 7. The architecture shall provide equivalence of both input and output to all parties
MSAN Voice Access - Security
• 8. The architecture shall not require an operator to reveal their internal bearer network topology.
• 9. The architecture shall not require an operator to reveal their control network topology.
• 10. The architecture shall not make any assumptions about physical network security.
• 11. In order to maintain network integrity, authentication and privacy shall be provided for signalling between networks:
• The architecture shall provide for signalling privacy between networks.
• The architecture shall require authentication between the networks.
• 12. The architecture shall not be defined in such a way that policing/policy enforcement of the interface becomes impracticable.
MSAN Voice Access - Management
• 13. The architecture shall allow operator A to provision an endpoint on operator B’s MSAN.
• 14. The architecture shall allow relevant events from operator B’s MSAN to be received by operator A.
Is this a job for Network Hooks?
