•
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.
Loopback Config (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—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.
Send Code (dsx1SendCode)
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
•
dsx1Send511Pattern—Sending a 511 bit fixed test pattern
•
dsx1Send3in24Pattern—Sending a fixed test pattern of 3 bits set in 24
•
dsx1SendOtherTestPattern—Sending a test pattern other than those described by this object.
Error Injection (linkInjectError)
Force an output error to see if the other end detects it
