–
IIH—Sets the Intermediate System to Intermediate System Hello PDU propagation frequency.
The IS-IS Hello PDUs establish and maintain adjacencies between ISs. The default is 3 seconds.
The range is 1 to 600 seconds.
–
IS-IS Cost—Sets the cost for sending packets on the LAN subnet. The IS-IS protocol uses the
cost to calculate the shortest routing path. The default metric cost for LAN subnets is 20. It
normally should not be changed.

and provision the following fields:
–
Mode
AITS—(Default) Acknowledged Information Transfer Service. Does not exchange data until a
logical connection between two LAP-D users is established. This service provides reliable data
transfer, flow control, and error control mechanisms.
UITS—Unacknowledged Information Transfer Service. Transfers frames containing user data
with no acknowledgement. The service does not guarantee that the data presented by one user
will be delivered to another user, nor does it inform the user if the delivery attempt fails. It does
not provide any flow control or error control mechanisms.
–
Role—Set to the opposite of the mode of the NE at the other end of the RS-DCC.
–
MTU—Maximum transmission unit. Sets the maximum number of octets in a LAP-D
information frame. The range is 512 to 1500 octets. The default is 512. You normally should not
change it.
–
T200—Sets the time between Set Asynchronous Balanced Mode (SABME) frame
retransmissions. The default is 0.2 seconds. The range is 0.2 to 20 seconds.
–
T203—Provisions the maximum time between frame exchanges, that is, the trigger for
transmission of the LAP-D “keep-alive” Receive Ready (RR) frames. The default is 10 seconds.
The range is 4 to 120 seconds.

Note
EOC (DCC Termination Failure) and LOS (Loss of Signal) alarms are present until you create
all network DCC terminations and put the DCC termination optical ports in service.
Note
There are four possibilities for the appearance of DCCs: green/solid, green/dashed, gray/solid,
gray/dashed. DCC appearance corresponds to the following states: active/routable,
active/nonroutable, failed/routable, or failed/nonroutable. Circuit provisioning uses
active/routable links. Selecting a node or span in the graphic area displays information about the
node and span in the status area.
Step 10
Return to your originating procedure (NTP).
