The PDG/TTG operates on the ASR 5000.
Components
The following application and line cards are required to support the PDG/TTG on an ASR 5000:
System Management Cards (SMCs): Provides full system control and management of all cards within the ASR
5000. Up to two SMC can be installed; one active, one redundant.
Packet Services Cards (PSCs/PSC2s): Within the ASR 5000, PSCs/PSC2s provide high-speed, multi-threaded
PDP context processing capabilities for 2.5G SGSN, 3G SGSN, and GGSN services. Up to 14 PSCs/PSC2s
can be installed, allowing for multiple active and/or redundant cards.
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.
can be installed; one active, one redundant.
Ethernet 10/100 and/or Ethernet 1000 Line Cards: Installed directly behind PSCs, these cards provide the
physical interfaces to elements in the operator’s network. Up to 26 line cards should 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/PSC2s do not require line cards.
loaded system with 13 active PSCs/PSC2s, 13 in the upper-rear slots and 13 in the lower-rear slots for
redundancy. Redundant PSCs/PSC2s do not require line cards.
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
