Central Site Remote Access Switch 257CONFIGURING A LTERNATE ACCESSESFrame Relay Accesses8. 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 theassociated DLCI. This is the index number that should be used when issuing various frame relayaccess console commands.You may continue to define PVCs on the currently selected line up to the limit available for thissystem. The limit is currently a total of 192 PVCs. If you configure more than one Frame Relayaccess, the total number of PVCs for all accesses can not be greater than 192.FRAME RELAY G ENERAL CONFIGURATION E LEMENTSNote: If you are unsure of any of any of these values, use the default values where provided.LINE ID N UMBERFrom the displayed list of available lines, the Id Number of the previously defined line that is to beused for this frame relay connection.F RAME R ELAY A CCESS NAMEThe user-defined name that will be used to identify this frame relay access. This name can be astring with 1 to 16 characters, using non-blank alpha-numeric characters.D ATA R ATEThe data rate that applies to the line being used for this frame relay access.BEARER CHANNELSA 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 from1 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 numberof 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 exampleframe relay access would be 128 Kbps.M AXIMUM FRAME S IZEThe maximum frame size supported by the network (including the endpoints).HDLC D ATA P OLARITYIndicates whether or not HDLC Data is sent over the line inverted.LINK FAILURE D ETECTIONYou may enable or disable link failure detection. If enabled, when Frame Relay detects a linkfailure, a backup procedure will be followed for the corresponding remote device. Link FailureDetection is only supported across PPP permanent virtual circuits. Some Frame Relay networks
