Item Description
Ignore the Sending-Complete
Information Element in Setup
Messages
• Enable for outgoing direction—Configure the ISDN protocol to send
Setup messages without the Sending-Complete Information Element
when placing a call.
• Enable for incoming direction—Configure the ISDN protocol to
ignore the Sending-Complete Information Element in Setup messages
when receiving a call.
• Enable for bidirectional directions—Configure the ISDN protocol to
ignore the Sending-Complete Information Element in Setup messages
when receiving a call, and to send Setup messages without the
Sending-Complete Information Element when placing a call.
• Disable (default)—Configure ISDN not to ignore the
Sending-Complete Information Element in Setup messages. During
data exchange between the device and an ISDN switch, for an
incoming call, if a Setup message does not contain the
Sending-Complete Information Element, the number is not received
completely. For an outgoing call, a Setup message containing the
Sending-Complete Information Element indicates that the number is
sent completely.
ISDN Sliding Window Size Set the sliding window size on an ISDN BRI interface.
ISDN T302 Timer Duration Configure the duration of the ISDN protocol Layer 3 timer T302.
ISDN Call Reference Length
Set the length of the call reference used when a call is placed on an ISDN
interface.
The call reference is equal to the sequence number that the protocol
assigns to each call. It is 1 or 2 bytes in length and can be used cyclically.
When the device receives a call from a remote device, it can automatically
identify the length of the call reference. However, some devices on the
network do not have this capability. In the event that the device is required
to place calls to such a device connected to it, you must configure the
device to use the same call reference length configured on the connected
device.
