Control Network Interface
IP-SVR (IP Server Interface)
This is a 10/100 BaseT Ethernet interface used to connect to the Control network. This interface
is available through the backplane I/O as well as through the faceplate. When the IPSI I/O
adapter is plugged onto the Amphenol connector, located on the rear of the carrier, the
backplane connections will be selected, otherwise, connectivity to the faceplate will be selected.
For the PN control carriers, the backplane connections are available only when the new PN
control carriers are used.
Services Interface
This is a 10/100 BaseT Ethernet interface accessible from the faceplate for services personnel
to configure the IPSI firmware (IP address settings), access the SAT, and to debug the control
network connectivity (ping, traceroute, etc.).
PN’s Maintenance Board Interface (TN2312AP)
This interface consists of RS232 transmit and receive leads and reset leads that connect to the
PN’s TN775D Maintenance board via the faceplate or the backplane. Communication Manager
talks to the Maintenance board via the IPSI’s archangel through this interface for cabinet
maintenance (cabinet temperature, voltage, emergency transfer and etc.). This interface also
allows the Maintenance board to reset the IPSI board when it detects insanity of the IPSI’s
archangel. When the ribbon cables are connected between the IPSIs and the PN’s TN775D
Maintenance board, the faceplate connections are selected, otherwise the backplane
connections are used. The backplane connections are available only when the new backplane
is used. This connection will not support the RS-232 SAT connection via the PN’s Maintenance
board.
Environmental maintenance (TN2312BP)
The TN2312BP IP Server Interface (IPSI) provides environmental maintenance and is the only
IP server interface that is supported in the G650. A TN2312BP can only be placed in a G650
with a carrier address set to A or B. Only a TN2312BP in a G650 with a carrier address set to A
provides environmental maintenance. The TN2312BP is backward compatible with the
TN2312AP, but provides environmental maintenance only when used in a G650. The
TN2312BP always provides tone detection, call classification, tone generation, and clock
functions.
When the TN2312BP is used in an MCC1 or SCC1, a TN775D provides the environmental
maintenance.
The TN2312BP provides environmental maintenance for the G650. This includes:
● External device alarm detection
● Emergency transfer control
● Customer-provided alarm device control
