Services Control

Access to service can follow two paths:

• IN (AIN/INAP/convergence sublayer-1 [CS-1]) platforms such as SCPs interface initially over standards-based AIN/INAP interfaces transported over the SS7 network, with future migration to IP-based transport.

• Service node services (such as calling cards and voice mail) initially connect over TDM PRI interfaces. In the future, the service node platforms will transition to IP networks to avoid unnecessary TDM/IP inter-working.
