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 20).

Terminal and Modem Cables

The following terminal and modem cables are described in this section:
■
RJ-45 terminal cable
■
Modem cable
■
Macintosh serial cable
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.
