Egressing-Frame Queues
(Multiple queues are used to support the prioritization of the traffic classes.)
For frames
egressing the unit‟s
local drop port
(GMII interface)
For frames
egressing the
left Line port
(per TDM pipe)
For frames
egressing the
right Line port
(per TDM pipe)

Output Rate Limiting
Each of the 8 ports is individually configurable to:
- none
- 128 kbit/sec
- 256 kbit/sec
- 512 kbit/sec
- 1 Mbit/sec
- 2 Mbit/sec
- 4 Mbit/sec
- 8 Mbit/sec
Each of the two GigE ports is also configurable to:
- 100 Mbit/sec
- 200 Mbit/sec
- 400 Mbit/sec
- 800 Mbit/sec
Dynamics:
The frames egress one frame at a time, with the inter-frame gaps set to
provide the configured average bit-rate.
Frame Priorities
Priority Source
The source priority may be taken from:
3-bit Priority field in 802.1p ingressing frames.
3-bit Priority field in 802.1Q ingressing frames.
