MAX 6000/3000 Network Configuration Guide Preliminary January 4, 2001 5-11
For example, if the MAX expects a Status Enquiry from the DTE every ten seconds, it records
an error if it does not receive a Status Enquiry in ten seconds.
Figure 5-5 shows an example of the MAX with a UNI-DCE interface.
Figure 5-5. Frame Relay DCE interface
The following parameters specify nailed group 36 as the bandwidth for the sample DCE
interface. Make sure that the Frame-Relay profile specifies the correct nailed group.

With these link management settings, the MAX uses the CCITT Q.933 Annex A link
management protocol to communicate with the CPE endpoint. It expects a Status Enquiry at
intervals less than seven seconds.
On a UNI-DCE interface, if the datalink is up, the DLCI is considered to be up as well. In the
DCE Full status response to the DTE, if a PVC segment terminates within the DCE, it is
reported as active. If the PVC segment is not terminated, the DCE has to request further
information on the Frame Relay network. In that case, it requests information about the DLCI
from the next hop switch, and reports back to the DTE when the segment is confirmed to be
active or inactive.
