<vcprofile>

<vcllc>

<ubrcbr>

=The name of the virtual channel profile (up to 31 ASCII characters). You cannot change the DEFVAL or DEFVAL_VC profiles.

=The type of encapsulation (vc or llc).

=The ubr (unspecified bit rate) or cbr (constant bit rate) ATM traffic class.

<pcr>	= Peak Cell Rate (0 to 300000 or *), the maximum rate
	(cells per second) at which the sender can send cells.
[cdvt]	= Cell Delay Variation Tolerance is the accepted
	tolerance of the difference between a cell’s transfer
	delay and the expected transfer delay (number of
	cells). 0 to 255 cells or * (means 0).

<vbr(rt- vbr)nrt-vbr>

<scr>

<bt>

=The real-time (vbr) or non real-time (nrt-vbr) Variable Bit Rate ATM traffic class.

=The Sustained Cell Rate sets the average cell rate (long-term) that can be transmitted (cells per second). SCR applies with the vbr traffic class.

=Burst Tolerance this is the maximum number of cells that the port is guaranteed to handle without any discards (number of cells). BT applies with the vbr traffic class.

The vcprofile setcommand creates a virtual channel profile. After you create a virtual channel profile, you can assign it to any of the ADSL ports on any of the ADSL MSAP2000 AAMSs in the MSAP2000 AAMS.

The following example creates a virtual channel profile named gold that uses LLC encapsulation. It uses constant bit rate and has the maximum rate (peak cell rate) set to

300,000 cells per second. The acceptable tolerance of the difference between a cell’s transfer delay and the expected transfer delay (CDVT) is set to 5 cells.

The following example creates a virtual channel profile named silver that uses VC encapsulation. It uses real-time variable bit rate and has the maximum rate (peak cell rate) set to 250,000 cells per second. The acceptable tolerance of the difference between a cell’s transfer delay and the expected transfer delay (CDVT) is set to 5 cells. The average cell rate that can be transmitted (SCR) is set to 100,000 cells per second. The maximum number of cells that the port is guaranteed to handle without any discards (BT) is set to 200.

The following example creates a virtual channel profile named economy that uses

LLC

encapsulation. It uses unspecified bit rate and has the maximum rate (peak cell rate) set to 50,000 cells per second. The acceptable tolerance of the difference between a cell’s transfer delay and the expected transfer delay (CDVT) is set to 100 cells.
