Switch Processor Input/Outputs (SPIOs): Installed in the upper-rear chassis slots directly behind the
SPCs/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: The following rear-loaded line cards are currently supported by the system:
Ethernet 10/100 and/or Ethernet 1000 Line Cards: Installed directly behind PSCs, 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 PSCs/PSC2, 13 in the upper-rear slots and 13 in the
lower-rear slots for redundancy. Redundant PSCs/PSC2s 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 PSC/PSC2 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.

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/Ethernet 1000/Quad Gig-E/10
Gig-E 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/PSC2a.
