Glossary: NAP

A Network Access Point (NAP) is the entry point to another network or destination peer, such as a SIP proxy. Think of it 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
