Physical description
The NTVQ55AA ITG Pentium (ITG-P) card supports IP Phones by
providing a communication gateway for the IP Phone between the IP data
network and the system. The IP Phone uses the IP data network to
communicate with the ITG-P card.
You can install this card in any two consecutive IPE slots.
Note: Each MG 1000S supports up to two ITG-P cards. Each
MG 1000S Expansion supports up to two ITG-P cards. Each ITG-P card
occupies two slots.
ITG-P cards have an ELAN management 10BaseT port and a TLAN VoIP
port (10/100BaseT) on the I/O panel. There is an RS-232 Maintenance port
connection on the ITG-P card faceplate and an alternative connection to the
same serial port on the I/O backplane.
Note: Do not connect maintenance terminals to the faceplate and I/O
panel serial maintenance port connections at the same time.
