2.3.4 Telephone Line Connection
The modem is supplied with a cord and standard plug ready for connection
to a PSTN circuit. If the PSTN line is terminated with a different style
socket, or a terminal block, contact the network provider to obtain a
suitable socket (see the postcard at the rear of this manual).
Unless the separate earth connection has been used, the mains plug must
first be inserted in a power outlet (to earth the modem), before connecting
the modem to the PSTN line.
All connections to the PSTN network must be via a standard plug and
socket, and must not be hard wired. See Figure 2-1.
If you want to use the modem on a leased line, refer to the Appendix
entitled 'Technical Guide' for details of how to modify the modem. The
modem configuration must also be changed for leased line operation: see
Chapter 4 for details (AT command
&L ).
