■
Specialty Handsets
 are designed for those individuals who need greater 
functionality than that provided by the handsets on system phones and 
standard phones. For example, an amplified handset is available for all 
PARTNER phones for hard-of-hearing users. 
■
In-Range Out-of-Building (IROB) protectors
 are required to prevent 
electrical surges from damaging your system when phones or other 
standard devices (such as a doorphone) are installed in a location other 
than the building where the control unit is installed. The system supports 
the Lucent Technologies IROB protector, which provides coverage for up to 
3,000 feet (915 meters) for standard devices and 1,000 feet (305 meters) 
for system phones. (IROBs must be installed by a qualified technician.)
■
Off-Premises Range Extender (OPRE)
 allows you to connect a standard 
touch-tone phone beyond 3,000 feet (915 meters) in another building on 
the same continuous property. It also allows you to use a special circuit 
from your local phone company to provide off-premises station capability.
■
Electromagnetic Interference (EMI) filters
 allow you to block “noise” 
generated by a nearby radio station, as well as most electrical devices.
■
Caller ID devices 
allow you to store and process Caller ID information.
 
Although the system provides functionally integrated, multi-line Caller ID on 
system display phones, you can connect other devices provided you 
subscribe to the service from your local phone company and connect the 
device 
directly to the Caller ID line. 
You cannot install a Caller ID device 
directly to a PARTNER extension jack or to a combination extension jack. 
Refer to “Caller ID Devices” in the 
PARTNER Advanced Communications 
System Installation 
guide for installation details.
■
PCMCIA cards 
allow you to administer your system from your PC, either 
remotely or locally (Release 3.0 or later).
NOTE:
ACS Release 3.0 includes a PARTNER Remote Access PC Card, which 
allows the user to administer the system remotely
1
 and perform backup and 
restore functions. The PARTNER Remote Access PC Card is a PCMCIA 
card that can also be used to upgrade previous versions of PARTNER ACS 
to Release 3.0.
!
WARNING:
Remove all other PC Cards from the processor before initiating an upgrade.
