1. Introduction
®
The intelligent Tahoe 970 series PCI interface cards are
equipped with one or two G.703 ports working with throughputs up to
2048 kbps. The use of E1 streams never was that easy - now the data
stream may be plugged directly into the PC and the operating system
treats it as a regular network interface.
The built-in hardware HDLC controller fully services the data
transmission, thus the PC processor isn’t unnecessarily loaded.
Both Linux and FreeBSD drivers are available, supporting Frame
®
Relay, HDLC, Cisco HDLC, X.25 and synchronous PPP protocols.

2. Card installation
Following steps should be taken to install the card:
¡ disconnect the power cable from the power supply
¡ remove the case
¡ find an unoccupied PCI slot
¡ unscrew the masking plate in the rear of the free PCI slot
¡ insert the card into the slot (the card connectors should be
accessible through the rear opening in the case)
¡ screw on the card firmly to the case
¡ close the case and switch the power on
After installing the card connect the G.703 port to the external
G.703 device (e.g. a HDSL modem).
The G.703 port has a RJ-45 connector. The G.703 standard
doesn’t specify the connector pinout, but the pinout used is the most
common in the industry, thus in most cases a regular straight patch-cord
may be used to connect the card to the external device.
Anyway the pinout should be carefully checked before connecting
the DCE device. The RX+ pin of the card should be connected to the TX+
pin of the other device, the RX- pin to the TX- pin, TX+ to RX+ and TX- to
RX-.
