Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

6.
7. l MGC cabinet type:N610-22
p Width:600mm
p Depth:1000mm
p Height:2200mm
p The available space in the cabinet is 46U, while 1U = 44.45mm = 1.75 inch.
l 4 Frames in a MGC cabinet.
8. l Frame type: OSTA
p Width: 19 inches
p Height : 9U
p 21 standard board slots
9. l The SIU provides a 5-bit DIP switch S3, used for setting unit frame IDs.
l SIU : Board of MGC system, will introduce later.
10. l Setting unit Device Number
l When we install more than one UAP-MGC in the same network. This determines the device
number for avoiding the conflict.
11. l The DIP switch on the SIU determines the frame number. The SMU reads the DIP switch on
the SIU and retrieves frame number. For the relationship between the DIP-switch settings of
the SIU and the frame number, refer to chapter 3 “Boards” for details.
l Depending on different board types configured, UAP8100 MGC frames fall into three types:
p Basic frame
p Expansion frame
p Resource frame
12. l Basic frame must be configured in the integrated configuration cabinet. The basic frame
provides a number of external interfaces such as clock, E1, and IP.
l A basic frame can provide all service processing capabilities.
13. l The expansion frame is optional, and can be configured as service processing frames
depending on the subscriber capacity.
l Expansion frames cannot exist by itself. They must cooperate with the basic frame to
provide service processing functions.
14.
15. l This frame can be configured with the resource boards including the VRB and MSU. It
provides the resources for the external devices.
16.
17. l For different boards, the backup mode differs. Some boards can only adopt the master and
slave mode; some only the load sharing mode; and others either. Note that only one mode
can be adopted at one time.
l To work in the master and slave backup mode, two boards need to be inserted in paired slots.
and system description is ONEBACKUP.
l To work in the load sharing mode, system description is LOADSHARE.
18.
19. l SMU enables the following functions:

p Providing six external FE interfaces. And the HSC1 still provides one pair of GE interface.
l The HSCs work in active/standby mode.
l The difference between the HSC0 and HSC1 is that the latter provides one pair of GE interface.
The former is used in the basic frame and expansion frame. The latter is used in the resource
frame and provides the GE interface to connect to the core LAN Switch.
22. l The Alarm Unit (ALU) is a front board and installed in slot 16 in each frame. It provides the
following functions:
p Communicating with the SMU through the serial cable, and accepting the
instructions and commands from the SMU to control indicators.
p Checking the chassis temperature and reporting the related information to the SMU
through the serial port cable.

reporting the logically synthesized signals as the working status of the power system
to the SMU through the serial port cable, and displaying power board working and
in-position status by its indicators.
p Reporting error information and lighting the fault indicator when the temperature
sensor is faulty.
23. l The ALU collects the information of the UPWR through the serial cable embedded in the
backplane, and drives the indicators on the ALU to indicate the working status of the
UPWR.
l The UPWR adopts the 2+2 backup working mode.
24. l As the front board, the Fixed Calling Control and Signaling process Unit (CSU) is used together
with the back board EPI in pairs. The CSU enables the following functions.
l The CSU implements processing of call control and protocols, such as MTP3, ISUP, H.248 and
SIP. The CSU also forwards the M3UA messages.

and used together with the back board BFI in pairs. The IFM is used to receive and transmit IP
packets, process Media Access Control (MAC) layer messages, distribute IP messages and
provide IP interfaces together with the BFI.
l The alarm information generated by the IFM is reported to the SMU through the shared
resource bus.
l The IFMs work in active/standby mode.
27. l The Broadband Signaling Gateway (BSG) is used to process the IP packets after the IFM level-1
dispatch. It implements the following protocols:
p UDP
p SCTP
p M3UA
p H.248
l The alarm information generated by the BSG is reported to the SMU through the shared
resource bus.
l The BSGs work in load sharing mode.
28. l The Multimedia Signaling Gateway Unit (MSG) processes the following protocols:
p UDP
p TCP
p SIP
l The alarm information generated by the MSG is reported to the SMU through the shared
resource bus.
l The MSGs work in active/standby mode
29. l The Central Database Boards (CDBs) are the front board. As the database of the equipment,
the CDB stores all data of the following aspects:
p Call location
p Gateway resources management
p Outgoing trunk circuit selection
l The CDBs work in active/standby mode. At maximum, eight pairs of CDBs can be configured.
l The alarm information generated by the CDB is reported to the SMU through the shared
resource bus.
30. l The Voice Resource Board (VRB) is a narrowband media resource processing unit. It is the
front board, and used in pair with the back board ERI. Each VRB can function as independent
media resource server. The VRB processes the audio signals in real time. It collects and
generates DTMF signals, plays and records audio clips.
l The VRBs work in load sharing mode.
31. l The Media Resource Control Unit (MSU) is the front board in the resource expansion frame,
and used in pair with the back board MRI. Each MSU can function as independentmedia
resource server. The MSU processes the audio signals in real time. It collects and generates
DTMF signals, plays and records audio clips, plays video and provides multi-party
conference function.
l The MSUs work in load sharing mode.
32. l The EPI enables the following functions:
p Processing messages on MTP1 physical layer.
p Providing narrowband signaling physical interfaces for the CSU. The EPI is configured in

l CKI work in active/standby mode.
37.
38.
39. l Alarm path for front boards excluding ALU and UPWR:
p Alarm data through shared resource bus transmit to SMU
p SMU transmit it to BAM through serial bus
l Alarm path for back boards.
p Using serial bus ,boards transmit alarm messages
40.
41.
42. l The shared resource bus enables SMUs to load, manage and maintain all loadable boards
in the same frame, such as the IFM, BSG, CCU, CSU, CDB and MSG.
l There are two shared resource buses, namely A and B, in one frame. The bandwidth of
each shared resource bus is 2G bit/s.
l The states and resources of shared resource buses are arbitrated and managed by the
SMU.
l The SMU in the slot 6 manages the front boards in the left half of the frame through the
shared resource bus A.
l The SMU in the slot 8 manages other front boards except ALU and UPWR in the right half
of the frame through the shared resource bus B.
l The HSCs in the slots 7 and 9 are connected to the shared resource buses through the
internal PCI bus, and thus the shared resource buses are interconnected.
l Therefore, the SMU in the slot 6 makes full use of the HSC in the slot 9 and the shared
resource bus B to manage front boards in the right half of the frame.
l The SMU in the slot 8 makes full use of the HSC in the slot 7 and the shared resource bus
A to manage front boards in the left half of the frame.
43. l The CSU, CCU, BSG, MSG, IFM, SMU, and CDB in the OSTA frames act as the channel of
inter-board service through the Ethernet bus. It ensure that the system processing flows
are uniform and smooth.
l There are 2 Ethernet buses, namely A and B, in one frame. The bandwidth of each
Ethernet bus is 100 Mbit/s.
l Each Ethernet bus is connected to the HSCs in the slots 7 and 9.
44. l There is one H.110 bus in one frame. The bus provides a switching capability of 4096 time
slots. The H.110 bus provides the following functions:
p Service changeover between active and standby CSUs
p Transmission channel for reference clock signals inside the frame
l The H.110 bus can carry out the service backup function only when CSUs switch over.
Because E1 is invariably configured on EPIs, the EPI switchover will cause the interruption
of trunk circuits and interruption of signaling links.
l HW: Highway
45. l SMUs manage the boards that are not connected to a shared resource bus in a service
processing frame through the serial port bus.
l Applicable boards include CKIs, EPIs and ALUs. The baud rate of the serial port bus is 38.4
kbit/s.
l Slave nodes of master or slave serial ports also include monitor board of power distribution
box and fan box. The baud rate for the monitor board to communicate with the master
node (SMU) is 9600 bit/s.
l SMUs make use of the shared resource bus and related front boards to manage back
boards without a processor, such as SIUs, HSCs and EPIs.
l SMUs make use of the serial port bus, ALU and two serial port wires embedded in the
backplane to manage UPWRs.
