Loud Ringing Bell/Headset Upgrade (HHEU)
The Loud Ringing Bell/Headset upgrade (HHEU) enables an external speaker (HESB) for the
Loud Ringing Bell feature and/or a headset to be connected to both series of digital telephones.
Notes
●
There are two types of HHEUs: the HHEU1 (which has four versions, V.1~V.4) and the
HHEU2.
●
Both 2000- and 1000-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.
●
1000-series digital telephones cannot be equipped with the HHEU (any type or version) and
the integrated data interface unit (PDIU-DI) at the same time, but 2000-series digital
telephones can support an HHEU and a RPCI-DI or PDIU-DI2 at the same time.
