Loud Ringing Bell/T001B Headset Upgrade (HHEU)

The Loud Ringing Bell/Headset upgrade (HHEU) enables an external speaker (HESB) for the
amplification of the telephones speaker or a T001B unit, to be installed to allow a loud
ringing bell or flashing device and a headset to be connected to the 2000- series of digital
telephones.
Notes
There are two types of HHEUs: the HHEU1 (which has four versions, V.1~V.4) and the
HHEU2.
The 2000- series digital telephones require either an HHEU2 or a V.3 or V.4 HHEU1 for
HESB operation; earlier HHEU1 versions are only sufficient for headset operation only.
Only digital telephones equipped with an HHEU2 can be wall mounted. The HHEU2 is
identical to the V.4 HHEU1, except that the HHEU2 has longer wires to accommodate
wall mounting.
A Toshiba HESC-65A cable is required to connect the HHEU in a digital telephone to
the HESB.
2000-series digital telephones can support an HHEU and a RPCI-DI at the same time.
The DKT2001-F will not support the HHEU.
