Netopia R3100 manual Easy Setup

Easy Setup 7-15

Note: The default configuration for the model R3100-I is No LMI as an LMI Type and DLCI 16 is statically configured. This is appropriate for current versions of the Copper Mountain DSLAM firmware. Future versions of the Copper Mountain firmware may support multiple statically configured DLCIs or DLCIs other than 16, or an LMI setting other than No LMI. In that case there may be no need to statically configure DLCIs at all since the router may be able to detect what DLCIs are configured between it and the DSLAM. Consult your service provider, CE200 documentation, or technical notes from Copper Mountain for DSLAM configuration.

The following configuration information is provided for options available in future versions of the Copper Mountain firmware.

1.Select LMI Type (Link Management Type) and press Return. From the pop-up menu, highlight either ANSI (Annex D), CCITT (Annex A), LMI, or No LMI. The default is No LMI. Press Return.

See “Frame Relay DLCI configuration” on page 7-16 for instructions.

Specifying the Link Management Type is the first step in configuring Frame Relay.

■If you select an LMI Type (Link Management Type) other than None, the T391 option specifies the number of seconds between the Status Enquiry messages. The default setting is 10.

■The N391 option specifies the frequency of full status polls, in increments of the basic (T391) polling cycle. The default setting is 6.

■The N392 option specifies the maximum number of (link reliability, protocol, and sequence number) error events that can occur within the N393 sliding window. If an N392 threshold is exceeded, the switch declares the Netopia Router inactive. The default setting is 3.

■The N393 option allows the user to specify the width of the sliding N392 monitored event window. The default setting is 4.

2.Select Tx Injection Management and press Return. From the pop-up menu, highlight Standard if you want the frames on your line that exceed the configured service parameters to be dropped at the router, Buffered if you want the frames on your line that exceed the link capacity to be delayed until the link is less busy, or None if you want all of the frames on your line to be transmitted. Press Return.

Note: If you select None as the Tx Injection Management type, the three Tx Injection Management options listed below will remain hidden. Go to step 4.

If you select Standard or Buffered as the Tx Injection Management type, then the Default CIR, Bc, and Be values will appear (in the corresponding fields below the Tx Injection Management field) in order for you to define the parameters the management algorithm.

■The Default CIR (CIR also referred to as Committed

Information Rate) represents the average capacity available to a given PVC (Permanent Virtual Circuit) or DLCI (Data Link Connection Identifier). This setting defaults to 64000, but you may modify the capacity rate if this setting will not be applicable to you.

■The Default Bc (Bc also referred to as Committed Burst Size) represents the maximum amount of data that your Frame Relay service provider agrees to transfer from a given PVC (Permanent Virtual Circuit) or DLCI (Data Link Connection Identifier). This setting defaults to 64000, but you may change the capacity rate if this setting needs to be modified.

■The Default Be (Be also referred to as Excess Burst Size) represents the maximum amount of data that your Frame Relay service provider will attempt to deliver to a given PVC (Permanent Virtual Circuit) or DLCI (Data Link Connection Identifier). This setting defaults to 0, but you may change the capacity rate if this setting needs to be modified.
