SmartEdge 600 Router Hardware Guide
The SAR devices also support enhanced queuing and shaping functions
for more granular control over traffic management with two, four, or eight
distinct CoS queues for each ATM PVC and allow a mix of priority- and
class-based queuing for each ATM PVC. These additional capabilities
allow the card to support subscriber circuits. For information about ATM
PVC and traffic management support, see related documentation at
https://ebusiness.ericsson.net.
This card is the same size as all other SmartEdge line cards and occupies
a single slot in the chassis.

(1) Each optical port has separate connectors for the transmit (Tx) and receive (Rx) circuits.
(2) The link power budget is calculated using (minimum output power) – (minimum sensitivity) – (optical path power
penalty); the power penalty is 1.
