4- AND 8-LINE CALLER ID
Caller ID data for some or all lines is garbled.
• Make sure that the data rate and data format settings of your Caller ID units
match those of the DTE and each other (see
Section 3.2
).
• If only one of the four or eight lines of a Caller ID unit is malfunctioning,
check the unit’s DATA LED to see if it flashes when data is sent. If it isn’t,
there might might be a problem with the RTS signal, or there might be a
hardware fault somewhere.
• If you’re daisychaining, make sure that the unit numbers of all of the Caller ID
units are set correctly (see
Section 3.2
).
6.3 Calling Black Box

make it worse; and

6.4 Shipping and Packaging
If you need to transport or ship your Caller ID unit:
