4.3.6Variable Bit Rate (VBR) Configuration Screen

The ACS-ATM card supports four super-rate channels up to 2.048 Mbps each. The aggregate bandwidth cannot exceed 4.096 Mbps.

Additionally, the card is capable of supporting up to 64 HDLC channels operating at Nx64 kbps (N = 1 to 32). The other 64 channels are accessed by using the “greater than” (>) and “less than” (<) symbols. The total HDLC bandwidth available for variable-bit-rate (AAL 3/4 & 5) traffic on a single ATM Server is 8 Mbps.

Alternatively, only C1can be used as an Ethernet controller. The ACS-ATM card is equipped with a single 10base-T Ethernet connector. In addition to the 8 Mbps of VBR traffic from the HDLC controllers, the Ethernet port provides encapsulation for Ethernet MAC layer frames. With this release of the product, no filtering or forwarding is supported by the card. All frames on the Ethernet are transmitted to the ATM aggregate port.

Figure 4-6shows a typical Variable Bit-Rate (VBR) Configuration Screen. To go to that screen, press “v” (Vbr command) in the ACS-ATM Card Main Screen. Table 4-8lists the actions you can perform from this screen, and Table 4-8shows the option settings and defaults.
