CHAPTER 2 CIRCUIT CARD EXPLANATIONS
1. GENERAL
This chapter provides detailed explanations for the following circuit cards:
•PA-8 IPTB
•PZ-8VCTB
2. PA-8IPTB (IPTRK Circuit Card)
2.1 General Function
PA-8IPTB is a Line/Trunk circuit card that is used for providing CCIS/FCCS service via the Intranet, and
to send/receive voice or FAX (G3) information over IP. PA-8IPTB is equipped with a total of eight ports,
however, an optional sub board (PZ-8VCTB) provides an additional eight ports, when mounted on a PA-
8IPTB main board. For more detailed information, see Section 2.6 External Interfaces. This card provides
the following functions:
a.) Voice Data Processing:
•Voice data compression/decompression
•FAX data encoding/multiplexing
•DTMF (analog signal) detection/transmission
•Echo Canceller
b.) IP Network Interface (10/100 Mbps Ethernet interface to send/receive voice/signal information)
c.) FCCS Link Interface
d.) LP-PM Bus Interface (for PM bus dedicated to NEAX2400 IPX series)

Note 1: When using an IPTRK circuit card for CCIS Networking via IP [C-163], the IPTRK cards in the self node
and its connected node must be in 1-to-1 ratio.
Note 2: Used for FCCS only.
Caution:While this circuit card is in use, some LSIs may get hot. Handle this card with care . Do not touch the he ated
LSI surfaces.
