UNIVERGE NEAX 2000 IPS Request For Proposal (RFP) Reference Guide Page 15-1

Chapter 15 Integrated Services Data Network (ISDN) ISDN Primary Rate Interface
ISDN is becoming a basic requirement for any PBX system sold today. The UNIVERGE NEAX
2000 IPS supports many ISDN BRI/PRI features and services. AT&T and Northern Telecom
specifications are both supported by the IPS. ISDN PRI trunks can use all of the same features
of the UNIVERGE NEAX 2000 IPS that any DID or DOD type trunk can use. For example, ISDN
PRI trunks can terminate to the PBX and use features such as Internal Automated Attendant,
DISA, Attendant Overflow, etc. In a typical installation, ISDN trunks will be terminated as DID
type lines, but the IPS also allows ISDN trunks to terminate as ring down type lines. As this
section will convey, the UNIVERGE NEAX 2000 IPS provides a very attractive ISDN PRI
package.

PRI Services & Features
Services provided by ISDN carriers are separate and different from features supported by
ISDN carriers. Services, in general terms, are often entire packages provided by the carriers,
such as AT&T’s Megacom®, which provides routing options and many reporting features.
Features of ISDN trunks provide the user with items such as Calling Party Number (CPN) and
Sub-Addresses. The distinction between services and features should be recognized to a
certain extent. This section will explain which features and services the UNIVERGE NEAX 2000
IPS supports.
