• Ranging SID—The SID assigned to the router by the CMTS.
• Registered—Indicates whether the router successfully registered with the CMTS.
• Privacy Established—Indicates whether the router established a BPI security session with the
CMTS.
• TFTP Server IP Address—Shows the IP address for the TFTP server that downloaded the DOCSIS
configuration file to the router.
• Time Server IP Address—Shows the IP address for the ToD server that provided the correct
time-of-day to the router.
• Time Zone Offset—Shows the time zone that the router has been configured to use.
• Downstream Info—Click this link to display the following downstream characteristics:
– DS ID—The Downstream ID assigned to the router.
– DS Frequency—The frequency in MHz of the downstream assigned to the router.
– DS Symbol Rate—The symbol rate currently used on the downstream.
– DS QAM Mode—The bandwidth used on the downstream (64 QAM or 25 6QAM).
– Signal-to-Noise Ratio Estimate—The current SNR calculated for the downstream.
– DS Lock Threshold—The minimum SNR signal that the router requires to maintain a lock on
the downstream signal.
• Upstream Info—Click this link to display the following upstream characteristics:
– US ID—The Upstream ID assigned to the router.
– US Frequency—The frequency in MHz of the upstream assigned to the router.
– US Power Level—The target power level that the router should be using on the upstream.
– US Symbol Rate—The symbol rate currently used on the upstream.
– Ranging Offset—The delay correction, in units of 6.25 microseconds, that the router must apply
to the CMTS Upstream Frame Time to synchronize upstream transmissions.
– Mini-Slot Size—The size of the DOCSIS mini-slots in units of 6.25 microseconds. Possible
values are 2, 4, 8, 16, 32, 64, or 128.
– Change Count—The DOCSIS configuration change count, which tracks how many times the
UCD parameters for a router have changed.
• Configuration File Info—Click this link to display the contents of the DOCSIS configuration file
that the router downloaded during its power-on provisioning.
