Abstract
A business performs a credit check on a customer'"'"'s credit card number by utilizing the D-channel of an Integrated Services Digital Network (ISDN) facility. The ISDN facility connects the business to a telecommunications network, which utilizes signaling system number 7 (SS7). Specifically, the ISDN Q.931 protocol is modified to allow the Q.931 FACILITY message to include: a) credit check request, b) a call reference number, and c) the customer'"'"'s credit card number. This information is sent, via the ISDN D-channel, to the telecommunications network, which passes the information, via an SS7 Transaction Capability Application Part (TCAP) message, to a credit checking data base. A result from the credit checking data based is then passed back through the telecommunications network to the business on the D-channel of the ISDN facility.
