4.2.3 ISDN

For SpringWare boards only. Currently ISDN cannot be used together with CSP on the same span on a board.

Certain DualSpan' products allow for ISDN on the first span and CSP on the second span. See the Release Guide and Release Update for more information on hardware support. See the Dialogic Technical Support web site at http://support.dialogic.com/tnotes/tnbyos/winnt/tn322.htm for a Tech Note on how to route a CSP voice resource to an ISDN network resource.

Alternatively, you can use ISDN and CSP together in a system by installing a Dialogic network interface product (DTI/SC) in your system in addition to the Dialogic voice product (such as a D/240JCT-T1).
