Excessive Error Rate.
End of Number.
Errored second. A second with one or more ESF error events (one or more CRC6
error events or OOFs).
Electrostatic discharge.
Extended Superframe. The T1 transmission standard that specifies 24 frames as an
extended superframe to be used for frame synchronization and to locate signaling
bits.
Federal Communications Commission.
Facility Data Link. The selected bits in the ESF format that are used for control,
monitoring and testing.
Line Build-out. The amount of attenuation of the transmitted signal that is used to
compensate for the length of wire between the transmitter and the receiver.
Liquid Crystal Display.
Light-Emitting Diode.
Loss of Frame. Occurs when a DS1 terminal is unable to synchronize on the DS1
signal for some interval (nominally 2 1/2 seconds).
Loss of Frame Count. A count of the number of LOFs declared.
Loss of Signal. The T1 line condition where there are no pulses.
Management Information Base. Database of managed objects used by SNMP to
provide network management information.
Multiplexer.
An error condition in which two out of four synchronization bits are in error.
Pulse Density Violation.

Quasi-Random Signal. A test pattern simulating a random pattern of digital ones
and zeros used to simulate normal transmission.
Shared Diagnostic Control Panel.
Severely Errored Seconds. A second with 320 or more CRC6 error events or one or
more OOFs occurring.
Serial Line Internet Protocol. A link layer protocol used by SNMP.
Simple Network Management Protocol. A generic network management system that
allows the device to be managed by any industry-standard SNMP manager.
Unavailable Seconds. A count of 1-second intervals when service is unavailable.
Volts alternating current.
Volts direct current.
Voice Frequency.
An outgoing signal transmitted when a DS1 terminal has determined that it has lost
