Q2: What is the maximum number of DTI server ports available on a TimeCreator 1000?
A: The maximum number of ports on the root server is 12.
Back to top

Q3: What is the maximum number of DTI server ports supported with a root-server implementation?
A: For a root server implementation, 132 DTI clients are supported with 12 subtending servers.
Back to top

Q4: Are the TimeCreator 1000 modules hot-swappable?
A: Yes
Back to top

Q5: How many IOC modules and power supplies are needed to operate the TimeCreator 1000?
A: Only one IOC module and one power supply is needed for operation, but you should use two of each for redundancy purposes.
Back to top

Q6: Is the TimeCreator 1000 AC or DC powered?
A: The TimeCreator 1000 has both AC and DC power supplies, but they should not be mixed.
Back to top

Q7: What is the baud rate to access the TimeCreator 1000's RS-232 Craft port?
A: For firmware versions 1.01.xx and above, the baud rate is 9600, but for firmware version 1.00.xx, the baud rate is 57600.
Back to top

Q8: To have GPS be the TOD-source for TimeCreator 1000, what are the requirements?
A: You need to install a GPS antenna and then set the TOD-source to "GPS" using the "set tod-source" CLI command.
Back to top

Q9: What is the difference between "RTC" and "User" for setting the TOD-source?
A: Setting the TOD-source to "RTC" will use the current time on the system, while setting the TOD-source to "User" allows the user to manually configure the date and time.
Back to top

Q10: To have a NTP server on the TimeCreator 1000, what are the requirements?
A: You will need to have a GPS antenna connected, set the TOD-source to "GPS," and purchase the NTP server option.
Back to top

Q11: What occurs if the external (TOD-source) reference is lost or not connected?
A: If the external TOD-source was never connected or synced, there will be no output and the IOC modules will be in Holdover. If the TOD-source was connected and lost, the IOC modules will go into Holdover.
Back to top

Q12: What are the three different external TOD-sources?
A: The three external TOD sources are; NTP, GPS, and DTI (the connection to the root DTI server).
Back to top

Q13: Which TOD-source is required on the subtending unit?
A: The subtending (slave) server must use DTI as a TOD-source.
Back to top

Q14: Which ports can be set for either the client or the server?
A: Both port 11/A and port 12/B can be set for either input or output signaling.
Back to top

Q15: Are the DTI output ports enabled by default?
A: Yes, the DTI ports 1-10 are enabled by default.
Back to top

Q16: What are the BITS ports used for?
A: Currently, the BITS ports are not used.
Back to top

Q17: What are the two SMB connectors on the IOC modules used for?
A: These two SMB connectors are only for test purposes. These connectors can be used for measuring 10 kHz and 10.24 MHz clock outputs.
Back to top

Q18: Which TOD-source setting must be used to support a NTP server?
A: The TOD-source must be set to "GPS" to support NTP.
Back to top

Q19: What is the current firmware version for the IMC and IOC modules?
A: The current firmware version for the IMC module is 1.02.04, and the current version for the IOC module is 1.02.03.
Back to top

Q20: Which command should be used when upgrading IOC modules on a TimeCreator 1000 with redundant IOC modules?
A: Use the following command: "upgrade ioc TCIOCMAIN_1_02_03.dld FTP-server-IP-address ftp auto-Reboot"

Note: Since DNS is not supported, FTP hosts must be entered with IP addresses, not hostnames.
Back to top

Q21: When should the "sync tod-source now" CLI command be used?
A: This command should only be used during the initial install phase or during a change to the TOD-source. Do not use this command in a production environment as it will cause any connected modems to re-range.
Back to top

Q22: What should be done with a "jam-sync required" alarm?
A: This alarm should be ignored, unless there have been changes to the TOD-source.
Back to top

Q23: How do you clear an "Output Port XX cable is disconnected" alarm?
A: Make sure that the cable is connected correctly and that the cable is not defective. If the cable is connected properly, the cable could be defective.
Back to top

Q24: Which command should be used to get the serial number of the IMC or IOC modules?
A: Use the "show inventory" CLI command.
Back to top

Q25: Which TOD-source must be used on the subtending unit? Which DTI ports must be connected to the root server and what is the correct mode setting for the ports?
A: The TOD-source setting must be "DTI" and the user must connect port 11 and/or port 12 to the root server. These port needs to be set to "client" mode.
Back to top

Q26: Which TOD-source must be used if you are using RSR (root server recovery)?
A: You must set the TOD-source to "User" on the root server, and set the TOD-source to "DTI" on the subtending server.
Back to top

Q27: What is the difference between root recover and root server recovery?
A: Please refer to the TimeCreator 1000 DOCSIS Timing Interface Server User's Guide and the Using Root Server Recovery with the TimeCreator 1000 Application Note for an in-depth answer. In simple terms, root recovery is always enabled, but for root server recovery (RSR), you will need to have a loop-back cable from a subtending server to the root server.
Back to top

Q28: Can root recovery and RSR be disabled?
A: Root recovery cannot be disabled, but RSR can be disabled.
Back to top

Q29: Which CLI command will show all the other commands?
A: The question mark ('?') lists all the CLI commands.
Back to top

Q30: Which command should I use to upgrade the IMC module?
A: Use the following command: "upgrade imc TCIMC1_02_04.rpm FTP-server-IP-address ftp auto-Reboot"

Note: Since DNS is not supported, FTP hosts must be entered with IP addresses, not hostnames.
