to“Bandwidth on Demand” on page 7-9 for further information about related fields in this menu.
Table 7-2. Remote Node PPP Options Fields
Field Description
Encapsulation Select CCP (Compression Control Protocol) for the PPP or MP link. Two options
are available in this field:
• Standard PPP—Standard PPP options are used (default).
• CISCO PPP—Cisco Systems PPP options are used.
Compression Allows the negotiation of data compression with the remote node router.
BACP The Bandwidth Allocation Protocol (BACP) is an extension to the Multilink
Protocol that lets two routers negotiate some of the parameters and behavior of a
Multilink connection. Because of incompatibilities among various
implementations of BACP, the default setting is BACP off.
Multiple Link Options:
BOD Calculation
Select the direction of the traffic you want to calculate in order to determine when
to add or subtract a link. The default for this field is Transmit or Receive.
Base Trans Rate
(Kbps)
Select the base data transfer rate for this remote node. This parameter is in
kilobits per second (Kbps). Two options are available for this field:
• 64—Only one channel is used (default).
• 128—Two channels are used when a packet triggers a call.
Max Trans Rate
(Kbps)
Enter the maximum data transfer rate allowed for this remote node.
This parameter is in kilobits per second. There are two options for this field:
• 64—At most, one channel can be used (default).
• 128—A maximum of two channels can be used.
Target Utility
(Kbps)
Enter the two thresholds separated by a hyphen ( - ) for subtracting and adding
the second channel. This parameter is in kilobits per second. The default is
32-48.
Add Persist This parameter specifies the number of seconds that traffic must be above the
adding threshold before the router brings up the second channel. The default is
5 seconds.
Subtract Persist This parameter specifies the number of seconds that traffic must be below the
subtraction threshold before the router drops the second channel. The default is
5 seconds.
