BC 321
The Danish Telegraph Agency has defined the following new types of apparatus: Telephone set BC 321, CB extension and Telephone set BC 331, Automatic extension.  Both have no incoming ringer, so must be in earshot of the main bell in the premises.

Additional - Dated 1933
These two types of apparatus are intended to replace the CD 567 switchboard for CB telephones and the CD 568 exchange for Automatic telephones.

The BC 321 can be used as an auxiliary device for all CB terminals in use (i.e. BD 360 and BC 300 model 1908 and model 1925).

BC 331 can be used as an extension to all Automatic terminals established so far (i.e. BD 370, BC 310, BC 316 and BC 330). If, in the case of a new installation of an auxiliary unit, the terminal unit is not a Bakelite model the latter may not be replaced for this reason.
