"Does the DCB Plus repeat Caller ID to the telephones connected to the TEL port?"
Yes, the Caller ID is captured and repeated to all phones downlinked to the TEL port. If you have a
corded phone or cordless phone system base connected there, then all corded phones and cordless
handsets to that base will receive the repeated Caller ID. When a call comes in, the phone company's
Caller ID information will display on the DCB Plus and ring all extension phones with caller ID connected
to the telephone line, but the DCB Plus will only suppress the first ring to the TEL port to prevent it from
ringing and receiving Caller ID. If the caller is an Invited caller, then the Caller ID information will display
on the first ring to the phones connected to the TEL port thereafter. This stops unwanted Caller ID
information from Blocked callers from being received by the phones connected to the TEL port, like Out
of Area, Unavailable, Anonymous or a Blocked caller's number.
2-Line Phones
The DCB Plus is a single line operation and the 2-conductor line cord supplied with it only carries a single
line. If you want to process both lines on your 2-Line phone, then you will need: Two DCB Plus with their
supplied single line cords, Two 2-Line Splitters with two single line cords and one Line Coupler. You will
use one splitter at the phone wall plate and connect the two supplied single line cords from each DCB
Plus to that splitter; L1 to DCB Plus 1 and L2 to DCB Plus 2 then connect the two single line cords from
each DCB Plus TEL phone port to the second line splitter L1 and L2. Connect this splitter to the Line
Coupler and then connect the 2-Line phone to the coupler.

How do I connect the DCB Plus to a DSL line?
Some DSL duplex filters have DSL Modem (ADSL) and Phone written on the filter jack, so you would
connect the DCB Plus to the Phone port of that jack. If the DSL filter is a single port, then connect the
DCB Plus to the DSL filter where your phone was connected, then connect your phone to the TEL port of
the DCB Plus.
If you have both DSL and cable systems, then the same is true for DSL above when you are using the
PSTN line for voice communication (telephone service). A DSL filter would not be used on a cable
modem if you get your telephone service there. Alternatively, you may have DSL filters for every phone
or device in service on the line. In which case you just connect the DCB Plus to the DSL filter then to the
phone service.
