Configure one PVC between the VDM port and the video source port, either
local or remote, using the SET PVC command:
SET PVC local_slot.port pvc_id remote_slot.port remote_hub_number path_type
local_vpi remote_vpi bw_alloc bandwidth
local_slot.port The slot and port number for a local end of the PVC.
pvc_id This allows you to define multiple PVCs per port.
remote_slot.port The slot and port number for the other end of the PVC.
remote_hub_number
The hub number (13th byte of the ATM address) of the
other hub. Can match the local hub number for local
PVCs.
path_type Specifies the type of virtual path connection.
local_vpi The vp.vc value for the local end of the PVC. See
Table 5 for allowable values.
remote_vpi The vp.vc value for the other end of the PVC. See
Table 5 for allowable values.
bw_alloc The bandwidth allocation algorithm to be used:
−
BEST_EFFORT
− RESERVED_BANDWIDTH
bandwidth The amount of bandwidth to allocate, if bw_alloc has
been set to RESERVED_BANDWIDTH.
