Field/Command

Description

LOS

Displays the number of Loss of Signal (LOS) Seconds: A second during which the

QUAD 2164 module is in a Loss of Signal state. LOS is declared upon detecting 100

consecutive zeros, it is cleared with the receipt of the next 1 bit.

LOF

Displays the number of Loss of Frame (LOF) Seconds: An LOF alarm is declared when

a 3-second interval of continuous Out of Frame (OOF) or Loss of Signal (LOS) state is

detected. If least 10 seconds elapse without an LOS or LOF error, the LOF alarm is

cleared.

AIS Rx/Tx

Displays the number of Alarm Indication Signal (AIS) Seconds (received and

transmitted): A count of one-second intervals containing one or more AIS defects. AIS

is an unframed ALL-ONEs bit pattern that indicates an alarm condition exists

upstream in a circuit leading to the downstream equipment. This is also called an

ALL-ONEs Keep-Alive or Blue Alarm Signal. An AIS defect is declared when there are

three or fewer zeros in 512 bit times and there is an LOF defect. It is cleared when

there are three or more zeros in two frames or the LOF defect no longer exists.

RAI Rx/Tx

Displays the number of Remote Alarm or Remote Alarm Indications (RAI) received

and transmitted. It is the alarm a receiving channel bank or multiplexer sends to the

other end of the circuit when it detects a Loss of Signal or Loss of Frame. There is a

2- to 3-second integration period upon detection of LOS or LOF before an alarm is

sent to the far-end equipment. This condition is also referred to as a Yellow Alarm.

SLIP

Indicates a timing slip error condition.
