CO Trunk Interface - ISDN-PRI
The System supports ISDN-PRI with the VB-44540 ISDN PRI Interface unit. The VB-44540 is a T/S-
Point ISDN-PRI that supports 23 B (bearer) channels and 1 D (data) channel (23B + D; 1544kbps). 
This unit connects to an ISDN DSU.
Up to 3 units may be installed in a cabinet if you use full channel (23B + D or 24 B). A maximum of 
18 units may be utilized in a fully equipped system. When all 24 channels on a unit are utilized, 3 slot

Computer Telephony Integration Capability
Description
Computer Telephony Integration (CTI) coordinates communications between computers and the 
telephone system. This is accomplished by using a Telephony Application Programming Interface 
(TAPI) server to connect the DBS 576 with a Local Area Network. 
LAN TAPI is designed to enhance the DBS 576’s performance by supporting both standard and 
custom computer telephony applications. A TAPI Service Provider (TSP) resides on a host computer 
running Windows NT Server/Version 4.0 or greater. Beginning with Version 3.0 and higher, CTAPI 
has been added to support LAN TAPI. (See LAN TAPI on p. 3-36 for additional information.)
