The ringer equivalence number (REN) is used to determine the quality 

of devices which may be connected to the telephone line.  Excessive 

RENs on the telephone line may result in the devices not ringing in re-

sponse to an incoming call.  In most, but not all areas, the sum of RENs 

should not exceed five (5.0).  To be certain of the number of devices 

that may be connected to a line, as determined by the total RENs, con-

tact the local telephone company.  

Note: REN is associated with the analog telephones.  It is not applica-

ble to Siemens “OpenStage” IP-based telephone.  If requested, please 

supply the product identifier in the format US:AAAEQ##TXXXX or the 

REN of the FCC Part 68 registered front-end host terminal equipment

operations, or procedures that can affect the operation of your equip-

ment.  If they do, you should be notified in advance so you have an op-

portunity to maintain uninterrupted telephone service.

Telephones for emergency use and telephones installed in common ar-

eas such as lobbies, hospital rooms, elevators, and hotel rooms must 

have handsets that are compatible with magnetically coupled hearing 

aids.  Persons who are not in common areas must also be provided 

with hearing-aid compatible handsets, if needed.

ible and complies with the FCC Rules, Part 68, Section 68.316 Hearing 

Aid Compatibility and 68.317 volume control requirements.

gency numbers using Siemens products with programmed dialer fea-

tures, stay on the line and briefly explain to the dispatcher the reason 

for the call before hanging up.  Perform these activities in off-peak 

hours, such as early morning or late evening.

model purchased be installed in the ac outlet to which the power sup-

ply for Siemens “OpenStage” IP-based telephone is connected.  Con-
