Battery Feed Test (also called Port Diagnostic Test) (#35)

Battery Feed Test (also called Port Diagnostic Test) (#35)

The battery feed chip provides power to the telephone equipment, signaling, rotary dial pulsing, transmission, and balance. This test checks the signaling and switchhook capabilities of the battery feed chip by terminating the port, applying battery, and trying to detect a current.

Error Code	Test Result	Description/Recommendation
	ABORT	Could not allocate the necessary system resources to run this test. Retry the command at 1-minute intervals for a maximum of 5 times.
1000	ABORT	System resources required to run this test are not available. The port may be reporting an external device alarm. Enter test external-device-alarm port GGGVSpp to determine if the port is reporting an EXT-DEV failure before retesting. When the port has no EXT-DEV failure, retry the command at 1-minute intervals for a maximum of 5 times.
1004	ABORT	The port received an EXT-DEV failure during the test. The test has been aborted. Enter test external-device-alarm port GGGVSpp to determine if the port is reporting an EXT-DEV failure before retesting. If the port has no EXT-DEV failure, retry the command at 1-minute intervals for a maximum of 5 times.
2000	ABORT	Response to the test request was not received within the allowable time period.
2100	ABORT	Could not allocate the necessary system resources to run this test. Retry the command at 1-minute intervals for a maximum of 5 times.
	FAIL	The port's battery feed chip is unable to supply sufficient power to sense the external device alarm. This may occur when the test is performed at the same time that the external device contact closure occurred. Enter test external-device-alarm port GGGVSpp to determine if the port is reporting an EXT-DEV failure before retesting. Wait until the port has no EXT-DEV failure before retesting. Retry the command at 1-minute intervals for a maximum of 5 times.
	PASS	The port's battery feed chip is able to provide power to the external device alarm to detect contact closure.
