Queue length: Limits the queue size
in packets of a particular VC.
Real-time variable bit rate (VBR):
Supports VBR data traffic with
average and peak traffic parameters.
ATM1 ATM2 IQ Comments
Supported Supported For ATM1 interfaces, when an OAM F5 loopback request is
received, the response cell is sent by the PIC. The request
and response cells are not counted in the VC, logical interface,
or physical interface statistics.
For ATM2 IQ interfaces, when an OAM F5 loopback request
is received, the response is sent by the routing engine. The
OAM, VC, logical interface, and physical interface statistics
are incremented.
See "Defining the ATM OAM F5 Loopback Cell Period" on
page 337 and "Configuring the ATM OAM F5 Loopback Cell
Threshold" on page 337.
Supported Supported See "Enabling Passive Monitoring on ATM Interfaces" on
page 301.

Not Supported Compared to non-real-time VBR, real-time VBR data is
supported serviced at a higher priority. Real-time VBR is suitable for
carrying packetized video and audio.
