Data Processing Card

Minimum of 4 DPCs for 1:N

redundancy;

Upto 8 possible

Manages subscriber sessions and

controls traffic

Provides system memory, compute

capacity, and crypto functions

DPC has two identical subsystems,

each with 12 CPU cores and 96 GB

RAM

20


Management and I/O Card

Provides chassis management and

physical I/O

Each MIO has:

One CPU subsystem with 96 GB of

RAM

Four NPU subsystems

Physical interfaces

20 x 10-GE ports + 2 x GE ports on

one MIO

10-GE ports support SFP+ LR or SR

optics

GE ports are 1000BASE-T copper

21


Fabric Storage Card

FSC and SSC

• 2 x 600 GB FDX crossbar fabric per FSC

4.8 Tbps FDX max.

• 2 x 2.5-in. SAS HD/SSD, RAID 5

• 2 x 200 GB SSD – 1.2 TB total system capacity

Inter Chassis Session Recovery

• Provides 1:1 redundancy in case of failures

• Uses propriety Service Redundancy Protocol (SRP) over TCP link

• Needs a separate context for SRP

• Configuration must be identical

• Tasks peers between two chassis

• Session states are synchronized between the chassis pair

• Session states checkpoint starts after 60 seconds for call establishment
