BT Adaptor Cable for the AT-AR027 PIC

The AT-AR027 VoIP-FXS PIC uses a standard RJ-11 connector. To connect
telephones with a BT-style connector, use an RJ-11 to BT adaptor cable
(Figure 24).

Notes:
(1) The SHUNT line (RJ11 pin 5/BT jack pin 3) is only required by some phones. If not
connected they will not ring.

Terminal and Modem Cables

Figure 25 on page 39 shows how to wire a cable to connect a standard VT100-
compatible terminal to an asynchronous (RJ-45) port. Some terminals are fitted
with a DB25 female connector rather than a DB25 male connector. In this case
the cable should be fitted with a DB25 male connector.
Figure 26 on page 39 shows how to wire a cable to connect an asynchronous
(RJ-45) port to a modem.
An alternative method, for both terminal and modem cables, is to wire an RJ-45
patch cord (a straight pin-to-pin cable with RJ-45 connectors on both ends) and
then use an RJ-45-to-DB25 adaptor wired internally as a crossed cable. These
adaptors are available in both DB25 female and male versions from data
cabling suppliers, and are supplied with wires terminated on the RJ-45 socket
and pins on the free ends. The pins are inserted into the appropriate positions
in the DB25 shell.
Figure 27 on page 40 shows how to wire a cable to connect an asynchronous
(RJ-45) port on the router or switch to the COM port on a Macintosh.
