CCASS/3 Terminal (C3T)

 
Q12 What is the software configuration required for C3T?


The software configuration required for the C3T is MS Windows Vista Business (32-bit), MS Windows 7 Professional (32-bit or 64-bit) or MS Windows 8.1 Pro (64-bit)Windows XP or Windows Vista or Windows 7. Please note that HKEX will revise the compatible platform for C3T from time to time, Participants should refer to Section 7.1 of Terminal User Guide at the link http://www.hkex.com.hk/eng/market/clr/secclr/ccass3/parttug/Documents/Sect7_1.pdf for the detailed C3T software configuration.

Q13 Can Participants open multiple browsers on the same C3T?


No.  Participants should open only one browser on a C3T. If Participants open multiple browsers on the same C3T, these browsers could interfere with each other and cause processing errors.

Q14 If a Participant wants to install more than one C3T, are multiple network lines required?


Subject to the line speed, a single network line can support multiple C3Ts.  In other words, a Participant can install multiple C3Ts in the same office using the same network line.

Q15 Can Participants install non-CCASS/3 related software in C3T?


Participants may install common applications such as MS Word, Excel in C3T provided that the PC meets at least the minimum system configuration to run a C3T. However, Participants are not recommended to install other custom-built applications in C3T.

Q16 Can a Participant access CCASS/3 by connecting the internal LAN in his office to the CCASS/3 network?


Yes, attaching C3Ts to an internal LAN which has connection with the CCASS/3 network is one way to access CCASS/3.  However, Participants electing this access method should be aware of the need to implement Network Address Translation (NAT) when setting up their internal LAN.  Each CCASS Participant is pre-assigned a range of IP addresses for defining his own C3Ts according to the “IP address Allocation Guidelines”.  CCASS/3 will validate the IP address when Participants attempt to logon CCASS/3 via C3T.  When a Participant set up internal LAN in his office, the internal LAN may carry IP addresses different from the ones pre-assigned by CCASS/3.  Under such situation, Participant should implement NAT so that CCASS/3 is able to recognise the IP address assigned to the C3T. In addition, the NAT should be a one-to-one mapping of the C3T.  That is, IP address of each C3T should be translated to a unique value within the original IP address range.

Q17 Can Participants install the C3T in their overseas offices?


Yes, Participants can install the C3T in their overseas offices with HKSCC’s prior written approval. According to General Rules of CCASS (“CCASS Rules”) 3901, any Participant that wishes to install or to access and operate CCASS from a foreign jurisdiction must obtain HKSCC’s prior written approval. And Participants should obtain from a reputable law firm of a foreign jurisdiction a legal opinion issued in favour of HKSCC for the CCASS operation and the placement of the CCASS Terminal in a foreign jurisdiction in accordance with CCASS Rules 3904. For the details of access to CCASS from a foreign jurisdiction, please refer to CCASS Rules Chapter 39 (http://www.hkex.com.hk/eng/rulesreg/clearrules/ccassgr/documents/r39.pdf).

Q18 How can Participants connect to CCASS/3 from their overseas offices?


There are two options to arrange the connection:

1. Participants can access CCASS/3 from their overseas office by extending their internal network in their Hong Kong office to their overseas office.  The network connection arrangement will be transparent to HKEX and Participants may arrange by themselves.
2. Alternatively, Participants may opt to access CCASS/3 from their overseas office by directly connecting the network of their overseas office to the CCASS/3 Network in Hong Kong.  Feasibility of this alternative is subject to the availability of local network carrier in relevant overseas location which has service arrangement with the vendor of SDNet, the service provider of the CCASS/3 Network in Hong Kong.  Participants who opt for this alternative should provide detailed address of their overseas office to HKEX.  HKEX would forward the case to the vendor of SDNet for checking and the vendor of SDNet would get back to Participants accordingly.  Participants should note that they would subject to the charges levied by the overseas carrier if this alternative is elected.

In either case, Participants need to acquire their own PC which can meet the C3T configuration requirements.  Participants can acquire smartcard readers and smartcards from HKEX for their C3T and operation staff in overseas office.  Participants should note that HKEX would not provide any on-site support for the C3T installed in their overseas offices and Participants would need to perform C3T commissioning themselves.
