Frame Relay Accesses
8. Indicate whether or not Congestion Control should be enabled.
9. Enter the Rate Measurement Interval in msecs.
Note: You must restart the CyberSWITCH in order to associate the PVC with a device.
After all of the above PVC information is entered, an index number will be assigned to the
associated DLCI. This is the index number that should be used when issuing various frame relay
access console commands.
You may continue to define PVCs on the currently selected line up to the limit available for this
system. The limit is currently a total of 192 PVCs. If you configure more than one Frame Relay
access, the total number of PVCs for all accesses can not be greater than 192.
F RAME R ELAY G ENERAL C ONFIGURATION E LEMENTS
Note: If you are unsure of any of any of these values, use the default values where provided.
L INE I D N UMBER
From the displayed list of available lines, the Id Number of the previously defined line that is to be
used for this frame relay connection.
F RAME R ELAY A CCESS N AME
The user-defined name that will be used to identify this frame relay access. This name can be a
string with 1 to 16 characters, using non-blank alpha-numeric characters.
D ATA R ATE
The data rate that applies to the line being used for this frame relay access.
B EARER C HANNELS
A list of bearers (a channel map) that will be used on the line associated with this frame relay access.
This parameter is required for PRI and BRI lines. For PRI lines, the range of bearer channels is from
1 to 24.For BRI lines, the range of bearer channels is 1 to 2. To enter the list of bearer channels,
separate the bearer channels by commas, and/or list a range by using a dash (-).
Note: The bandwidth available for this access is equal to the data rate multiplied by the number
of bearer channels used by this access. For example, if the configured data rate is 64 Kbps,
and 2 bearer channels have been configured, the bandwidth available for this example
frame relay access would be 128 Kbps.
M AXIMUM F RAME S IZE
The maximum frame size supported by the network (including the endpoints).
HDLC D ATA P OLARITY
Indicates whether or not HDLC Data is sent over the line inverted.
L INK F AILURE D ETECTION
You may enable or disable link failure detection. If enabled, when Frame Relay detects a link
failure, a backup procedure will be followed for the corresponding remote device. Link Failure
Detection is only supported across PPP permanent virtual circuits. Some Frame Relay networks
