Easy Setup 7-13
Note: The default configuration for the model R3100-C is appropriate for current versions of the Copper
Mountain DSLAM firmware. Future versions of the Copper Mountain firmware may suppor t 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 ser vice 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 7-14 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 Enquir y 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 ser vice 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 Vir tual 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 ser vice provider agrees to transfer from a given PVC (Permanent Vir tual 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 ser vice provider will attempt to deliver to a given PVC (Permanent Vir tual 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.
