YellowFormatFrame12FS(3)—FS bit of frame 12
) (<)
This describes which implementation of FDL is being used, if any. FDL applies only to T1 circuits.
•
other(1)—Indicates that a protocol other than one following is used.
•
dsx1Ansi-T1-403(2)—Refers to the FDL exchange recommended by ANSI.
•
dsx1Att-54016(3)—Refers to ESF FDL exchanges.
•
dsx1Fdl-none(4)—Indicates that the device does not use the FDL.
Test Settings
This portion of the

window contains information described in the following
sections.
5.5
This variable identifies which standard will be used to transmit and identify the Yellow Alarm.
•
linkYellowAuto—Do not force the transmission of a yellow alarm. But, yellow alarm may be automatically
transmitted.
•
linkYellowOn—Force the transmission of a yellow alarm even if the received signal is in frame.
•
linkYellowDisable—Do NOT transmit a yellow alarm even if the received signal is out of frame.
+.&- (<+.&-
This variable represents the loopback configuration of the DS1 interface. Agents supporting read/write access
should return badValue in response to a requested loopback state that the interface does not support. The val-
ues mean:
•
dsx1NoLoop—Not in the loopback state. A device that is not capable of performing a loopback on the
interface shall always return this as it's value.
•
dsx1PayloadLoop—The received signal at this interface is looped through the device. Typically the received
signal is looped back for retransmission after it has passed through the device's framing function.
•
dsx1LineLoop—The received signal at this interface does not go through the device (minimum penetra-
tion) but is looped back out.
•
dsx1OtherLoop—Loopbacks that are not defined here.
& (< &
This variable indicates what type of code is being sent across the DS1 interface by the device. The values mean:
•
dsx1SendNoCode—Sending looped or normal data
•
dsx1SendLineCode—Sending a request for a line loopback
•
dsx1SendPayloadCode—Sending a request for a payload loopback
•
dsx1SendResetCode—Sending a loopback termination request
•
dsx1SendQRS—Sending a Quasi-Random Signal (QRS) test pattern
