ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation
ITG ISL Trunk card physical description
The Meridian 24-Port ITG Trunk 2.0 card (NT0961AA) plugs into an
Intelligent Peripheral Equipment (IPE) shelf. Each ITG ISL Trunk card
occupies two slots. ITG ISL Trunk cards have a E-LAN management
Ethernet port (10BaseT) and a T-LAN VoIP Ethernet port (10/100BaseT) on
the I/O panel. The ITG ISL Trunk card has a DIN-8 serial maintenance port
connection on the faceplate and an alternative connection to the same serial
port on the I/O backplane. Do not connect two maintenance terminals to both
the faceplate and I/O panel serial maintenance port connections at the same
time.
The NT0961AA ITG ISL Trunk card supports 24 ports per card.
The core ITG processor is an Intel Pentium II (266 Mhz).
The ITG ISL 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.
