TN2312 IP Server Interface Circuit Pack
Note:
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, TONE-BD, SER-BUS,
CAB-EXFR, EXT-DEV, CAB-PFL, POW-SUP, CAB-TEMP, PS-RGEN,
CAB-CALM, and CAB-MTCE.
The TN2312 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 TN2312 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 TN2182C 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
(TN2312AP)
● Environmental maintenance (TN2312BP)
For S8700 systems, the processors, and the PKT-INTs reside 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:
