P-202H Plus v2 Quick Start Guide 5 Click Wizard Setup in the main menu to display the first wizard screen. 6 Use this screen to configure your ISDN line and how the P-202H Plus v2 handles incoming calls. Select from the B Channel Usage dropdown box. If you are using both B channes, select Switch/Switch (default). If you are only using one B channel (for example, your router is sharing the ISDN line with another device), then select Switch/Unused. If your second B channel is a leased line, select Switch/ Leased. In ISDN Data, enter the phone number (up to 25 digits) assigned to you by your ISDN service provider. If it's necessary to dial an additional number to reach an outside line, enter it in the Outside Line Prefix field. Enter the subaddress and telephone number assigned to A/B Adapter 1 or 2 (PHONE 1 or 2). The Incoming Phone Number Matching setting governs how incoming calls are routed. If you select Multiple Subscriber Number (MSN) or Called Party Subaddress, a call (either ISDN data or analog) is routed to the port that matches the dialed number; if no match is found, the call is dropped. Global calls are always ignored. A global call is an incoming analog call where the switch did not send the dialed number. This happens most often when the call originates from an analog telephone line. 4
