Page 20: Introduction To Isdn
Duet aurora Basic & Primary Rate ISDN Tester - User Guide The PRI aurora is designed to test the ISDN Primary Duet Rate Interface (PRI) at the 'T' reference point by emulating either a TE or an NT. For more information, see Equipment Interface Reference Points in this chapter.
Page 21: Interface Types
Introduction ISDN offers end-to-end (caller to receiver) digital connectivity between terminal equipments (TEs) via network terminating equipments (NTs) and digital exchanges, both private and public. Interface types Your aurora is designed to test the Basic Rate Interface Duet (BRI) which comprises three channels, collectively known as 2B+D.
Page 22: Equipment
Duet aurora Basic & Primary Rate ISDN Tester - User Guide Equipment There are two main types of ISDN equipment: • Terminal equipment (TE) • Network terminator (NT) Terminal Equipment This refers to end-user devices such as analog or digital telephones, X.25 data terminal equipment, ISDN workstations, or integrated voice/data terminals (IVDT).
Page 23: Equipment Interface Reference Points
Introduction Equipment interface reference points The various pieces of equipment connected to the BRI and PRI have their own interface classifications. The interfaces between a Terminal Equipment (TE) and a Local Exchange (LE), or Central Office (CO) are conceptually known as the ‘R’, ‘S’, ‘T’ and ‘U’ interface reference points.
