IP-SVR (IP Server Interface)
TN2312AP IP Server Interface Circuit Pack
NOTE:
The only error type reported against this MO is error Type 18. All other error
types will be reported against MOs supporting the IPSI circuit pack
functional modules, PKT-INT, IPSV-CTL, ETR-PT, TDM-CLK, TONE-PT, and
TONE-BD.
The TN2312AP IPSI circuit pack is used by S8700 systems to connect the port
networks to the media servers via an IP network and provide port-network control
functions.
The TN2312AP IPSI is inserted into the PN’s Tone-Clock slots and provides
interface back to the media servers via Ethernet. See the following list of IPSI
circuit-pack functions:
■
PKT-INT packet-bus interface
■
Archangel TDM-bus interface
■
Tone-Clock functionality (equivalent to TN2182B Tone-Clock circuit pack)
■
Ethernet interface for connectivity to the media servers
■
Ethernet interface for connectivity to Services’ laptop PCs
■
Maintenance-board interface for communication with the PN’s TN775
Maintenance board
For S8700 systems, the processors, and the PKTINTs are located in different
cabinets, connected to each other via the control networks. All communication
between the media servers and the IPSIs are done over TCP/IP Socket
connections. Other than the Ethernet that connects the media servers to the
IPSIs, there are no other leads for signaling and resets. All communication
between the media servers and the IPSIs must be done via messages over the
socket connections.
Each IPSI’s state of health (SOH) is kept with the following elements in
descending order of priority:
■
Tone-Clock
■
PKT-INT
■
Archangel
