Program *66-5 Overview
This program is used to assign seven-digit listed directory numbers per channel group. The index
number assigned is correlated to a CO line port number in Program *66-6 for direct inward ringing
assignments and to trunk groups in Program *66-7.
ISDN calls are originated and terminated using a listed directory number and call type (bearer
service). The Strata DK must know the listed directory numbers subscribed from the PSTN to
determine how to handle the call.
Wild card entries (*) are allowed for handling a larger number of LDNs. For example, a DID group
using 583-3700 through 583-3799 can be entered as a single LDN entry: 583-37**. To handle a
single number differently that falls within this range, enter that number in a lower number index.
e.g., Index 01 = 5833769 and Index 02 = 58337**. If a match occurs on Index 01, the call will be
handled based upon Index 01.
