Figure 1 displays the default settings of ILMI for the 9A686-04 and 9A656-04. The entire square
represents the total VPI/VCI range for all ATM Connections. This provides a VCI range of 0 through 16K
and a VPI range of 0 through 4095. VCI values 0 through 32 are reserved by the ATM Forum, as shown in
Figure 1. By default, the 9A686-04 and 9A656-04 are an SVC only switch. This allows SVCs to be
created with a VCI value between 32 and 16k. In addition, the default setting allows SVCs to use the
entire VPI range of 0 through 4095. The ILMI Configuration screen allows the user to either decrease or
increase the reserved VCI or VPI range that SVCs may use. Refer to
