IP trunk card description
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.
The IP trunk cards monitor the IP network for delay (latency) and packet
loss between other IP trunk cards. The card re-routes new calls to the
alternate circuit-switched trunk routes if the Quality of Service (QoS) of the
data network is not acceptable. Customers can configure QoS parameters
on the IP trunk cards to ensure that the IP Trunk 3.01 (and later) trunk route
is not used for new calls if the network QoS degrades below an acceptable
level. QoS monitoring is not available for Gatekeeper-routed endpoints
such as the CS 1000M.
