Test Parameters
This portion of the Test Details page contains Test Parameters options described in the following sections.
Force Yellow Alarm (linkYellowForce)
This variable identifies which standard will be used to transmit and identify the yellow alarm.
•
enable(1)—Force the transmission of a yellow alarm even if the received signal is in frame.
•
disable(0)—Do not transmit a yellow alarm even if the received signal is out of frame
Loopback Configuration (dsx1LoopbackConfig)
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(1)—Not in the loopback state. A device that is not capable of performing a loopback on the
interface shall always return this as its value.
•
dsx1PayloadLoop(2)—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(3)—The received signal at this interface does not go through the device (minimum penetra-
tion) but is looped back out.
•
dsx1OtherLoop(4)—Loopbacks that are not defined here.
Send Code (dsx1SendCode)
This variable indicates what type of code is being sent across the DS1 interface by the device. The values mean:
•
dsx1SendNoCode(1)—Sending looped or normal data
•
dsx1SendLineCode(2)—Sending a request for a line loopback
•
dsx1SendResetCode(4)—Sending a loopback termination request
•
dsx1SendQRSSCode(5)—Sending QRSS test pattern
•
dsx1Send511Code(6)—Sending 511 test pattern
•
dsx1Send3in24Code(7)—Sending 3 in 24 test pattern
•
dsx1SendOtherTestPattern(8)—Not defined
