Cisco ASR 5000 Series Product Overview ▄
OL-22938-02
Packet Services Cards (PSCs/PSC2s) : Within the ASR 5000 platform, PSCs/PSC2s provide high-speed, multi-
threaded PDP context processing capabilities for 4G P-GW services. Up to 14 PSCs/PSC2s can be installed,
allowing for multiple active and/or redundant cards.
Switch Processor Input/Outputs (SPIOs) : Installed in the upper-rear chassis slots directly behind the SMCs,
SPIOs provide connectivity for local and remote management, central office (CO) alarms. Up to two SPIOs
can be installed; one active, one redundant.
Line Cards: Installed directly behind PSCs, these cards provide the physical interfaces to elements in the E-
UTRAN EPC data network. Up to 26 line cards can be installed for a fully loaded system with 13 active
PSCs/PSC2s, 13 in the upper-rear slots and 13 in the lower-rear slots for redundancy. Redundant PSCs do not
require line cards.
Ethernet 10/100 and/or Ethernet 1000 line cards for IP connections to other network elements.
Redundancy Crossbar Cards (RCCs) : Installed in the lower-rear chassis slots directly behind the SPCs/SMCs,
RCCs utilize 5 Gbps serial links to ensure connectivity between Ethernet 10/100 or Ethernet 1000 line cards
and every PSC/PSC2 in the system for redundancy. Two RCCs can be installed to provide redundancy for all
line cards and PSCs.
