BT-CMTS-3000 ACL Management Access Control List (ACL) is used mainly to identify the streams. To filter the data packets, the network device is required to configure a series of matching rules to identify the packets to be filtered After identifying specific packets, corresponding data packets will be allowed to pass, or not, according to the preset strategy ACL classifies the data packets through a series of matching conditions, which can be source address, destination address, and port number of data packets ACL includes displaying ACL, adding ACL, modifying ACL, deleting ACL, deleting rules, and binding/ unbinding 19
BT-CMTS-3000 Upstream Parameters to be set include Management Status, Central Frequency, Bandwidth, Modulation Configuration Template, Channel Mode, Channel Type, and Receiving Level Click the checkbox ahead of each line to select multiple channels. Click Channel Off or Channel On on the toolbar to enable/disable multiple channels by batch Use Channel Offset to modify the Channel Center Frequency 20
BT-CMTS-3000 Downstream DOCSIS and the Closed Channel displays parameters including Channel ID, Management Status, Central Frequency, Channel Bandwidth, Modulation Mode, Level, System, Interleaving Depth, and Symbol Rate 21
BT-CMTS-3000 Spectrum Groups and Automatic Frequency Hopping Frequency Hopping avoids ingress noise in the RF plant Frequency Hopping is configured and activated using spectrum groups Spectrum Management supports the creation of a number of cable spectrum groups, allowing multiple upstream ports in a single spectrum group Each Spectrum Group defines the table of frequencies to be used in a specific frequency plan The Spectrum Group takes precedence, so both a spectrum group and a fixed frequency on an upstream can be configured. Spectrum Group overrides the fixed upstream frequency setting 22
BT-CMTS-3000 Spectrum Groups and Automatic Frequency Hopping If the noise impairment is of substantial duration, it may cause the cable modem to temporarily lose communication with the CMTS. For security, the user can reserve multiple channels or upstream frequencies for their subscribers. If one channel experiences too much interference, the CMTS requests that the cable modems hop to another channel. Frequency Hopping Waveform RF Power Frequency 23
BT-CMTS-3000 Internal DHCP Server Internal DHCP/TFTP server available for easy setup Assign IP address for both cable modem and CPE devices Support both IPv4 and IPv6 addressing Supports one address pool for IPv4 and one address pool for IPv6 Supports DNS and Gateway configuration Includes TFTP support to push configuration file to cable modem TFTP function can only send one cable modem configuration file to Cable Modems at a time. It does not support multiple configuration files at the same time. Cable Modem DHCP TFTP DHCP response TFTP request DHCP request TFTP request 24
BT-CMTS-3000 CPE Management CPE (Customer Premise Equipment) list displays CPE information under the CMTS according to the CM classification CPE List displays the total number of CPE and CPE basic information Displays CM of CPE, CPE number, MAC address of CPE, IP address of CPE, CPE type, and CPE lease time 25
