IP-SVR (IP Server Interface)
The IPSI circuit pack has the following interfaces:
Control Network 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
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. The Avaya MultiVantage software 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.
TDM-Bus Interface
The TDM bus is used by four different functions on the IPSI board:
1. When the Archangel module is activated, it uses the Spitfire2 device
2. In angel mode, the Tone-Clock angel uses the Spitfire2 device to
3. The Tone Generator uses the Spitfire2 device to put tones on the
4. The Tone Detector uses the NCE device to receive TDM bus time
555-233-143
to be the bus master of the TDM bus. The Archangel uses this
interface to talk to the other port boards' angels on the TDM bus.
