Card Descriptions
6.7 4-Port POS OC-48c/STM-16c Card
The 4-port POS OC-48c/STM-16c card functions as a network uplink module in
edge routing and BRAS applications. This card is a PPA2-based card and has
a minimum memory capacity of 1 GB.
This POS OC-48c/STM-16c card supports PPP, HDLC, FR encapsulations,
MDRR, and POS LAG features.
This card is the same size as all other SmartEdge line cards and occupies a
single slot in the chassis. This card requires a separate SFP transceiver for
each port.
The following types of SFP transceivers are supported on any of the ports:
• SONET OC-48/STM-16 SR-1—Short Reach
• SONET OC-48/STM-16 IR-1—Intermediate Reach
• SONET OC-48/STM-16 LR-2—Long Reach
