System Release 6.1 cPCI for Windows Release Guide — May 2006 19
SS7CPM8
The SS7CPM8 is a SS7 signaling interface board that supports up to four SS7 links
and provides eight T1/E1 interfaces.
Signaling Interface Units (SIUs)
Intel NetStructure Signaling Interface Units (SIUs) are SS7 server solutions that provide a
convenient and cost-effective way to add SS7 connectivity to an existing multi-chassis
system or to enable an application with the necessary protocols for mobile wireless or
intelligent networks. System Release 6.1 cPCI for Windows provides support for the
following SIUs:
SS7G21 (in SIU Mode)
The SS7G21 is fitted with Intel NetStructure SPCI4 or SPCI2S boards with a system
maximum of 12 SS7 links and provides a form, fit, and function replacement for the
Intel NetStructure SIU520 signaling gateway on a higher performance platform. An
SS7G21 may be purchased with either:
• 1, 2, or 3 SPCI2S boards (4 SS7 links, 2 T1/E1 interfaces, two V.11 serial ports
per board)
• 1, 2, or 3 SPCI4 boards (4 SS7 links, 4 T1/E1 interfaces per board) Supplied in a
2U carrier-grade chassis, the SS7G21 provides SS7 connectivity for multichassis
call control, wireless, or Intelligent Networking (IN) applications.
SS7G22 (in SIU Mode)
The SS7G22 is fitted with Intel NetStructure SS7HDP boards and offers significantly
greater performance and link density than the SS7G21. An SS7G22 may be
purchased with 1, 2, or 3 SS7HDP boards (64 SS7 links, 4 T1/E1 interfaces per
board) with a system maximum of 128 SS7 links. Supplied in a 2U carrier-grade
chassis, the SS7G21 provides SS7 connectivity for multichassis call control, wireless,
or Intelligent Networking (IN) applications.
SIU520
The SIU520 is a carrier-grade programmable 2U server that provides signaling for
multiple clients over a local area network (LAN). It supports up to 12 SS7 links and
provides up to 12 T1/E1 digital network interfaces and up to six V.11 interfaces
(offering V.35 interworking).
SIU231
The SIU231 is a modular design SIU enabling SS7 signaling boards to be added as
needed. It supports up to 16,384 circuit identification codes (CICs), up to 32 SS7 links
in eight linksets and handles 100 calls/second. It can connect to 32 host platforms
(significantly more using a host-clustering arrangement) and is suitable for creating
fault-resilient configurations.
SIU131
The SIU131 is an SIU that supports up to 4096 circuit identification codes (CICs), up
to six SS7 links in six linksets and handles 100 calls/second. It can connect to 32 host
platforms (significantly more using a host-clustering arrangement) and is suitable for
creating fault-resilient configurations.
