6.1 Safety instructions
•
Always disconnect the Telco connector before touching the CT-618 board or
before changing boards in the PC.
•
Never touch non-insulated telephone wires or terminals unless the telephone
line has been disconnected at the network interface.
•
Never install telephone wiring during a lightning storm.
•
Never install telephone jacks in wet locations unless the jack is specifically
designed for wet locations.
6.2 Wiring Configurations
In most cases, your incoming telephone service will be located in a
wiring/telephone closet. A punch down block will be used to distribute the wiring
to the individual lines and extensions, and a 25-pair cable is used to connect the
punch down block to the CT-618 board (see RJ21X Telco connector pinout).
A typical telephone installation is illustrated in Figure 1.
You can also set up a demonstration configuration by connecting the IBM
Computer Telephony server to a harmonica, as shown in Figure 2. Two phones
can be wired to each RJ11 as illustrated in Figure 3.
In order to connect and configure your IBM Computer Telephony system you
may need additional cables.
Note: To avoid noise pickup, do not wire telephone cable in parallel with an
AC power source or computer cable unless the cable is shielded.
