I/O cable assemblies
The Media Card 32-port trunk card and ITG-Pentium 24-port trunk card
provide a cost-effective solution for high-quality voice and fax transmission
over an IP network.
The IP Trunk cards are an IPE-based assembly designed for installation in a
Meridian 1/CS 1000M IPE shelf.
A Media Card 32-port trunk card occupies one slot and can have a maximum
of 32 ports. The ITG-Pentium 24-port trunk card is a two-slot trunk card and
can have a maximum of 24 ports. On the ITG-Pentium 24-port trunk card, a
Peripheral Component Interconnect (PCI)-based Digital Signal Processing
(DSP) daughterboard provides voice processing and supplies the packets to
the IP Trunk 3.01 (and later) network using a Pentium host processor. The
Media Card 32-port trunk card has the DSP connected to the main assembly.
This main assembly is what compresses speech into packets and supplies the
packets to the IP Trunk 3.01 (and later) network using an Intel StrongARM
(SA) processor.
