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.

FRAME RELAY GENERAL CONFIGURATION ELEMENTS

Note: If you are unsure of any of any of these values, use the default values where provided.

INE ID NUMBER

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.

RAME RELAY ACCESS NAME

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.

ATA RATE

The data rate that applies to the line being used for this frame relay access.

EARER CHANNELS

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.

AXIMUM FRAME SIZE

The maximum frame size supported by the network (including the endpoints).

HDLC D

ATA POLARITY

Indicates whether or not HDLC Data is sent over the line inverted.

INK FAILURE DETECTION

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
