Examples of a UNI-DTE link interface
On a UNI-DTE interface, the MAX acts as the user side communicating with the network side
DCE switch. It initiates link management functions by sending a Status Enquiry to the UNI-
DCE device. Status Enquiries may include queries about the status of PVC segments the DTE
knows about, as well as the integrity of the datalink between the UNI-DTE and UNI-DCE
interfaces.
DCE switch. It initiates link management functions by sending a Status Enquiry to the UNI-
DCE device. Status Enquiries may include queries about the status of PVC segments the DTE
knows about, as well as the integrity of the datalink between the UNI-DTE and UNI-DCE
interfaces.
The UNI-DTE uses the values of the N391, N392, N393, and T391 parameters in the Frame-
Relay profile to define the timing of its Status Enquiries to the DCE and its link integrity
parameters. (These correspond to the Ascend-FR-N391, Ascend-FR-DTE-N392, Ascend-FR-
DTE-N393, and Ascend-FR-T391 attributes in a RADIUS profile.)

Ascend-FR-T391 (166)
Link Integrity Verification polling timer. The value should be less
than that of Ascend-FR-T392. The default is 10, which indicates
that after Ascend-FR-N391 status requests spaced 10 seconds
apart, the UNI-DTE device requests a Full status report. Does not
apply when Ascend-FR-Type is Ascend-FR-DCE.

apply when Ascend-FR-Type is Ascend-FR-DCE.
Ascend-FR-T392 (167)
Interval in which Status Enquiry messages should be received
(from 5 to 30 seconds). The default T392 value is 15. An error is
recorded if no Status Enquiry is received within the specified
number seconds. Does not apply when Ascend-FR-Type is
Ascend-FR-DTE.

Ascend-FR-DTE.
Framed-MTU (12)
Maximum number of bytes the MAX can transmit in a single
packet across the link interface. Usually the default of 1532 is the
right setting. However, the far-end device might require a lower
number.

(162)
Number of errors which, if occurring in the number of DCE
monitored events specified by Ascend-FR-DCE-N393, causes the
network-side to declare the user-side procedures inactive. The
value should be less than that of Ascend-FR-DCE-N393 (which
can be from 1 to 10). Does not apply when Ascend-FR-Type is
