Non-Blocking Architecture
Description
The System is totally non-blocking. All extension and outside lines are available for use at the same 
time. 
Hardware Requirements
S-ICX: The CPC-HS supports 64 ports (max. 28 extensions and 24 digital extension ports). The 
CPC-HM supports up to 116 ports (max. 60 extensions and 24 digital extension ports).

Power Failure Transfer
Description
Power Failure Transfer provides telephone service to a limited number of Single Line Telephones 
(SLTs) during a power failure. The SLTs are connected to the trunk via a Power Failure Unit (PFU). In 
the event of a power failure, the power failure extensions have dial tone directly from the trunk. 
(System features and restrictions do not apply.)
Hardware Requirements
Power Failure Unit (VB-43703)
An SLT that will be connected to the PFU.
Considerations
Up to four SLTs can be connected to one PFU.
For added protection against power outages, backup batteries can be installed in the System. 
Backup batteries provide full telephone service and system features to all System extensions for 
a limited amount of time. With maximum traffic, the backup battery will last 15 minutes in the S-
ICX.
Power On Maintenance
Description
The System allows you to change most circuit cards, programming, and many other maintenance 
features while the System is powered on and operating. Very few operations require the System to be 
powered down or out of service. The System therefore continues to operate without interruption for 
most maintenance functions. 
A limited number of items such as the replacement of some common control circuit cards requires the 
system to be powered down.
