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.
