A Network Access Point or NAP represents the entry point to another network or destination peer (e.g. SIP proxy, ISUP interface peer, etc). A NAP can also be thought of as a trunk group.

TelcoBridges and Network Access Points

The Network Access Point (NAP) allows for service access points (SAPs), ISDN stacks, and SS7 ISUP interfaces to be associated as a combined resource for one type of access. A NAP is used to represent a collection of voice endpoints, for example: a group of SS7 CICs, ISDN controlled timeslots, SIP outgoing proxy to a specific provider, and more. NAPs are, later in the configuration process, used to define how calls are routed out of the Tmedia system.

NAP Types

  • SS7 (Signaling System 7)
  • ISDN (Integrated Systems Digital Network)
  • CAS (Channel associated signaling)
  • SIP (Session Initiation Protocol)
  • VOIP (Voice Over IP)
  • TDM (Time-Division Multiplexing)
  • Media-only (VoIP or TDM) for H248 controlled resources
