parameter to No, the data link does not come up unless a Connection profile (DLCI) brings it
up, and it shuts down after the last DLCI has been removed.
Note:
You can start and drop Frame Relay data-link connections the DO Dial and DO
Hangup commands. DO DIAL brings up a data-link connection. DO Hangup closes the link
and any DLCIs on it. If LinkUp=Yes, DO Hangup brings the link down, but it automatically
restarts. A restart also occurs if a Connection profile (DLCI) invokes the data link.
Defining the nailed connection to the switch
Nailed is the default for Frame Relay connections. When you define the call type as nailed, dial
numbers and other telco options are N/A. You can specify Switched if the Frame Relay switch
allows dial-in. However, Frame Relay networks currently have no dial-out connection
capability. The two types of data service available are 64K and 56K.
Specifying the type of Frame Relay interface
You can set the FR Type parameter to NNI (for an NNI interface to the switch), DCE (for a
UNI-DCE interface), or DTE (for a UNI-DTE interface). For more information, see “Kinds of
logical interfaces to a Frame Relay switch” on page 7-2.
Link management protocol
The Link Mgmt setting may be None (no link management), T1.617D (for T1.617 Annex D),
or Q.933A (for Q.933 Annex A).
Frame Relay timers and event counts
Frame Relay timers and event counts are as follows:
•
N391 specifies the interval at which the MultiVoice Gateway requests a Full Status Report
(between 1 and 255 seconds). Is N/A if FR Type is DCE.
•
DCE N392 specifies the number of errors, during DCE N393 monitored events, that
causes the network side to declare the user side procedures inactive. The value should be
less than that of DCE N393 (between 1 and 10). DCE N392 is N/A when FR Type is DTE.
•
DCE N393 specifies the maximum value for the DCE monitored event count (between 1
and 10). It is N/A when FR Type is DTE.
•
DTE N392 specifies the number of errors, during DTE N393 monitored events, that which
cause the user side to declare the network side procedures inactive. The value should be
less than that of DTE N393 (between 1 and 10). DTE N392 is N/A when FR Type is DCE.
•
DTE N393 specifies the maximum value for the DTE monitored event count (between 1
and 10). It is N/A when FR Type is DCE.
•
T391 specifies the Link Integrity Verification polling timer (between 5 and 30 seconds).
The value should be less than that of T392. T391 is N/A when FR Type is DCE.
•
T392 specifies the time for Status Enquiry messages (between 5 and 30 seconds). The
MultiVoice Gateway records an error message if it does not receive a Status Enquiry
message within T392 seconds. This parameter is N/A when FR Type is DTE.
