Chapter 15 Integrated Services Data Network (ISDN)

ISDN Data Modems

ISDN Data Modems will provide users with access to the Internet at speeds of 64 or 128 kbps. ISDN modems can place and receive ISDN calls at 56, 64, and 128 kbps. Data calls within the PBX or external using ISDN PRI can greatly increase the user’s productivity by using the higher rates of ISDN BRI. NEC America has successfully tested the IBM Waverunner series of ISDN modems.

Group four Fax

Fax machines capable of G4 can send faxes at speeds of 56 kbps using ISDN BRI.

System Requirements

BRI stations within the IPS can place calls to other BRI stations or outside the PBX by using ISDN PRI lines to the public network. Each IPS system can support up to 24 BRI Terminal ports.

The PN-2ILCA card is used for to connect the BRI terminal to the PBX. An SPN-SC03 card is required to control D channel activity for the BRI terminals. One SC03 card supports four 2ILCA cards. The UNIVERGE NEAX 2000 IPS can support 48 ILCA cards that mount in LT slots and 12 SC03 cards that mount in AP slots.
