What is lportISDNSourceAddr?

This read-only octet string holds the E.164, telephone-number-style, address identifying the originating end of the current ISDN connection on this port. An admin uses this to confirm exactly which remote site or device placed this ISDN call, useful when multiple possible ISDN backup sources could be calling into this port and the admin needs to verify the right one connected. For example, lportISDNSourceAddr showing an E.164 number matching a specific branch office's ISDN circuit confirms that branch's backup connection is the one currently active on this port, not some other site.
