num_streams
The maximum number of cell streams this module will be asked to simultaneously support.
Each cell stream shall be treated independently of the link bandwidth the cell stream consumes.
For an IMA bundle, each TDM stream within the bundle will be counted as separate.
•
vpi mask
This bitmask is required when the option bit is set for full configuration via masks, rather than use the
default mask (0x000f), which allows VPI values 0 to 15 inclusive to be used.
Note:
The VPI and VCI cannot both be 0.
•
vci masks
These bitmasks are required when the option bit is set for full configuration via 16 VCI masks - one for
each (of up to 16) VPI values configured. The default mask (0x01ff) allows VCI values from 0 to 511
inclusive to be used, although 0, 3, and 4 are reserved.
If fewer ports are being configured, then masks allowing more VPI/VCI combinations may be used.
Note:
The number of VPI/VCI combinations per cell stream multiplied by the number of cell streams
configured must not exceed 64 kbits/s.
