Telephone Speaker Off-hook Call Announce Upgrade (DVSU)
To receive Speaker Off-hook Call Announce (OCA) calls over the digital telephone speaker, a 
digital telephone must be upgraded with a DVSU; the telephone making the call does not require a 
DVSU. In a DK system with release 3 and above software, a DVSU is not required to receive OCA 
in the telephone handset or headset. An additional wire pair is not required for digital telephones 
that receive Speaker OCA calls. The DVSU is compatible with both 2000-series and 1000-series 
digital telephones.
Notes
lDigital telephones cannot be equipped with a DVSU and integrated data interface unit (PDIU-
DI, RPCI-DI or PDIU-DI2) or DADMs at the same time.
lProgram 03, Code 62 or 64 must be set for the PDKU and Code 28 for the RDSU for 
telephones that are to receive Speaker OCA and Program 31 LED 03 must be turned ON for 
telephone ports.
lDVSU is not necessary to receive handset OCA.

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
lThere are two types of HHEUs: the HHEU1 (which has four versions, V.1~V.4) and the 
HHEU2.
lBoth 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. 
lOnly 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.
lA Toshiba HESC-65A cable is required to connect the HHEU in a digital telephone to the 
HESB.
l1000-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.
HHEU Upgrade Installation 
See Figures 9-2 and 9-8~9-12 and follow 
these steps:
1. Loosen the four captive screws on the 
telephone base, and remove the base.
2. Use a screwdriver or other suitable tool 
to remove the plastic tab on the back of 
the base. (The HHEU modular 
connector for the headset is accessed 
through this opening.)
3. If installing a V.3 HHEU1, set the 
SW601 switch on the HHEU to headset 
for the headset or loud bell application.
V.4 HHEU1 and HHEU2 do not have 
this switch, because they are 
automatically set for the headset/loud 
bell application.
