TN2312BP IP server interface
Issue 6 February 2007 261
● Customer-provided alarm device (CPAD) control
CPAD provides a contact closure across a pair of external leads. These leads can control a
customer-provided alarm device or an alarm indicator. The level of alarm can be
administered system wide to cause a contact closure. The alarm levels are major, minor,
warning, or none. When the alarm level matches the alarm level that was administered, the
TN2312BP IPSI closes this contact for all G650s. This closure occurs by a carrier address
set to A. When the TN2312BP IPSI is in emergency transfer, this contact is closed to
activate the CPAD.
I/O adapters
The TN2312BP IPSI requires an adapter that provides for the alarm input, CPAD, and
emergency transfer leads. This adapter also allows the IPSI Ethernet connection to be made to
the back of the IPSI slot.
Compatibility
The TN2312BP IPSI can replace the TN2312AP IPSI in the following gateways:
● SCC1
● MCC1
● CMC1
● G600
However, the IPSI does not provide environmental maintenance for these media gateways.
Environment maintenance requires monitoring of the AuxSig backplane lead cabinet when the
TN2312BP is installed in a CMC1 or G600 media gateway with Communication Manager 2.0.
This lead sends an alarm if a failure is detected in either the power supply or fan assembly. The
CMC1 and G600 are supported only in a nondedicated control path configuration with
Communication Manager 2.0.
