ITG-Pentium 24-port trunk card (NT0961AA) 47
The NT0961AA ITG-Pentium 24-port trunk card supports 24 ports per card.
The core ITG processor is an Intel Pentium II (266 Mhz).
The ITG-Pentium 24-port trunk card is responsible for converting the 64
kbit/s Pulse Code Modulation (PCM) speech from the DS-30X backplane
interface into packetized speech for transmission over the IP network. On
the daughterboard, the DSPs compress speech and feed the resulting
packets to the IP network.
Figure 7 "ITG-Pentium 24-port trunk card system connectivity and
messaging" (page 47)
shows ITG-Pentium 24-port trunk card system
connectivity.The ITG card provides sufficient flexibility to emulate any
DS-30X signaling protocol. To support IP terminals, an ITG card emulates
the XDLC with attached Aries sets. Signaling on all DS-30 channels is
supported, allowing the ITG card to support up to 32 ports on a single card.
