▄ Cisco ASR 5000 Series Product Overview
OL-22938-01
Packet Processing Cards (PSCs/PSC2s/PPCs):In the ASR 5000 platform, packet processing cards provide
high-speed, multi-threaded PDP context processing capabilities for GGSN services. Up to 14 packet processing
cards can be installed, allowing for multiple active and/or redundant cards.
cards can be installed, allowing for multiple active and/or redundant cards.
Switch Processor Input/Outputs (SPIO): 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.
can be installed; one active, one redundant.
Line Cards: The following rear-loaded line cards are currently supported by the system:
Ethernet 10/100 and/or Ethernet 1000 Line Cards: Installed directly behind packet processing cards,
these cards provide the physical interfaces to elements in the LTE/SAE network. Up to 26 line cards
should be installed for a fully loaded system with 13 active packet processing cards, 13 in the upper-
rear slots and 13 in the lower-rear slots for redundancy. Redundant packet processing cards do not
require line cards.

rear slots and 13 in the lower-rear slots for redundancy. Redundant packet processing cards do not
require line cards.
Quad Gig-E Line Cards (QGLCs): The 4-port Gigabit Ethernet line card is used in the ASR 5000
system only and is commonly referred to as the Quad-GigE Line Card or the QGLC. The QGLC is
installed directly behind its associated packet processing card to provide network connectivity to the
packet data network.

10 Gig-E Line Cards (XGLCs): The 10 Gigabit Ethernet Line Card is used in the ASR 5000 system
only and is commonly referred to as the XGLC. The XGLC supports higher speed connections to
packet core equipment, increases effective throughput between the ASR 5000 and the packet core
network, and reduces the number of physical ports needed on the ASR 5000.

The one-port XGLC supports the IEEE 802.3-2005 revision which defines full duplex operation of 10
Gigabit Ethernet.

The XGLC is configured and monitored via the System Management Card (SMC) over the system‘s
control bus. Both SMCs must be active to maintain maximum forwarding rates.

Redundancy Crossbar Cards (RCCs): Installed in the lower-rear chassis slots directly behind the SMCs, RCCs
utilize 5 Gbps serial links to ensure connectivity between Ethernet 10/100 or Ethernet 1000 line cards/QGLCs
and every packet processing card in the system for redundancy. Two RCCs can be installed to provide
redundancy for all line cards and packet processing cards.
