●The KX-TAW848 is initially configured for 4 lines and 4 phones.
●Its maximum capacity is 8 lines and 51 phones (but all phones can't be in use at one time.)
●You increase capacity and add features by installing optional modules.
◄There are empty spaces ("slots") in
the 848 for two 4-port modules, two 8-
port modules, and four special feature
modules. Two of the special feature
slots are internal, with no openings for
external connections ("ports"). The
other slots are covered with temporary
"dummy cover plates" that can be
removed for module installation.
The top photo shows several added modules: one special
feature module on the left, one 4-port module in the center, and
two 8-port modules on the right. CLICK to see which modules
go where, and how to install them.

The KX-TAW848 can handle up to 8 lines and 51 phones (but they can't all be in use at the same
time).
  • The connection panel in the KX-TAW848 has spaces for four 4-port modules, and two 8-port
    modules.
  • There is also a space for the door intercom/opener module, and spaces that may be used for
    other modules in the future.
  • There are mounting locations inside the cabinet for modules that do not need ports for external
    connections.
  • The KX-TAW848 is equipped with two 4-port modules. One module, which can't be removed,
    can handle up to four multi-line or single-line phones.
  • The other is the KX-TAW8480, which can handle up to 4 phone lines ("CO lines").

  1. If you want to add more lines, you need a KX-TAW84880 module (4 ports).
  2. If you want to add more multi-line phones, you can use the KX-TAW84870 (4 ports) or
  3. KX-TAW84875 module (4 ports) or KX-TAW84876 (8 ports).
  4. If you want to add more single-line phones you can use the KX-TAW84870 module (4 ports) or
    KX-TAW84874 (8 ports).
  5. If you want to have door intercom speakers and/or remote unlocking, you need the KX-
    TAW84861 module.
  6. DSS/BLF consoles can connect to the KX-TAW84875 module (4 ports) or KX-TAW84870 (4
    ports) or KX-TAW84876 (8 ports) or the 4-port module that is permanently installed.
  7. Voice Processors can connect to the KX-TAW84875 module (4 ports) or KX-TAW84870 (4
    ports) or KX-TAW84876 (8 ports) or the 4-port module that is permanently installed.
  8. 28 of your phones could be wireless (of which up to eight could be in use at one time, through
    four cell stations). They can connect to the KX-TAW84870 (4 ports) or or the 4-port module that
    is permanently installed.


Since the KX-TAW848 has modular connections, installation is “plug and play.”  The design allows
people with an existing Panasonic phone system, like the KX-TA624 or KX-T616, to easily upgrade for
all the new features and greater capacity of a KX-TAW848. Simply unplug the line cords from the
previous control unit and plug them into a KX-TAW848. The existing telephones and cabling stay in
place, providing considerable savings in time and money.

IMPORTANT:
●The 4-port phone module that is permanently installed and the optional KX-TAW84870 4-port
module have "HYBRID PORTS" that can work with single-line phones, multi-line phones, DSS/BLF
consoles, voice processors, and KX-T0141 cell stations (wireless antennas).
●The KX-TAW84875 4-port phone module and KX-TAW84876 8-port phone module can work with
multi-line phones, DSS/BLF consoles, voice processors; but NOT single-line phones. or cell stations
