Telephone cable (not supplied)
Your computer does not work with party lines, cannot be connected to a coin-operated
telephone, and may not work with multiple telephone lines or a private branch
exchange (PBX). Some of these connections may result in excess electrical current
and could cause a malfunction in the internal modem.
If you connect a telephone cable coming through a splitter, the modem or connected
device may not work properly.
