j. This is the code that is generated when the link between the circuit pack
and the voice terminal is successfully reset. No craft action is necessary.
k. No terminal is connected to the Digital Line board. No maintenance action
is required.
l. An uplink message has been logged indicating that the Electric Power
Feed (EPF) is on with no load on it. No action is necessary.
m. The circuit pack’s message buffer is full. This may be caused by having
many display phones with heavy traffic connected to the circuit pack. No
action is necessary.
n. Internal system error. No action is necessary.
o. There is a problem with the voice terminal EEPROM. When the voice
terminal is repaired the alarm will be resolved with the passing of time.

Digital Terminal Remote Looparound Test (#1201)
This test checks the connection between the SPE and the digital terminal and the
ability of the terminal and the associated port to send and receive data. This test
is based on procedure 622 to isolate digital terminal problems.
A request is presented to the terminal to go into loopback mode. Data is sent to
the terminal and when received back, checked for consistency. This test is run as
a part of the "test long" procedure. It is not included in any error recovery strategy
