Abstract
A muldem (100) has a monitor (101) which automatically sequentially tests data paths through the muldem for detection of malfunctions in the muldem. Standby data path protective switching means (108, 109) provides alternate data paths through the muldem in the event of a malfunction. The monitor may be manually overridden and locked to a specified data path for continued analysis of such path. Additionally, a selected path may be manually locked out from switching to standby. The monitor automatically checks before switching any data path to standby, to prevent a selected path from being switched, while permitting automatic protective switching of the other data paths.
