• linkTaiwanR1(8)
Message-Oriented Switch Type (linkIsdnSwitchType)
This object allows the selection of the ISDN variations on the ISDN protocol, depending on the brand of
switch to which the access server is connected. This only needs to be set when messageOriented is chosen for
signalling protocol.
• ni1(0)—National ISDN-1
• dms(1)—Northern Telecom
• att(2)—AT&T Lucent
• ctr4(3)—E1 ISDN
• ts014(4)—Australia AUSTEL
• ins1500(5)—Japan
• nfasSlave(7)—T1 that uses the D channel of another T1 for signalling
NFAS Interface (linkNfasInterfaceId)
The ID number assigned to the PRI by the telephone company. The interface ID is used by the common D
channel to determine which PRI in the NFAS group will receive the incoming call.
NFAS Primary WAN (linkNfasPrimaryPointer)
The WAN port into which the PRI with the common D channel is plugged into.
Test Settings
This portion of the WAN Circuit Configuration window contains information described in the following
sections.
Force Yellow Alarm (linkYellowForce)
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.
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.
