Chapter 4 Configuration Tables and Fields
Bursty Table
Bursty Table
The Bursty Table contains topological information about Frame Relay, ATM, and circuit emulation
connections in the network. The important fields in the bursty table are the site ends, the type, and the
BackCard field. The type defines the type of connection (Frame Relay, ATM, Circuit Emulation, or multi
segment), and the backcard defines the connection type at the customer's premise. The MCR and PCR
fields define the load parameters of the connection, and are key to estimating the bandwidth utilization,
and the port speeds.
The primary CWM source of the Bursty table is the USER_CONN table. The WANDL file for translation is
the demand file. The Bursty Table fields are described in Table 4-7.
