Page 22: Cable Plant Issues
CMTS 1000 Installation Manual V1.2 Cable Plant Issues There is no simple formula to follow when configuring cable plants for cable modems. However, the goals are as follows: • Keep the Carrier-to-Noise Ratio (C/N) to 25 dB or better at all points on the cable.
Page 23 will only get worse as you add the C/Ns from all the other contributors (i.e., Coax plant, forward, reverse and forward fiber C/Ns). The above approach works as long as the noise level on the cable plant is low enough to allow combining a number of runs. If this is not the case, then it might be necessary to do the following: •...
Page 24: About The Cmts 1000
The CMTS 1000 is also fully compliant with the DOCSIS Baseline Privacy Specifications to ensure cable plant security and that end-to-end communi- cations are kept private. It provides comprehensive filtering capabilities based on packet type, address, port, or protocol, allowing cable operators to configure their security measures to fit their exact requirements.
Page 25: Benefits

Page 102 System Name parameter is displayed in the first or top line of the LCD dis- play. The actual System Name is displayed in the second or bottom line of the LCD display. If the CMTS 1000 has no System Name, then the LCD displays no system name set.
Page 103: Down Stream Menu
System Revision The System Revision parameter displays both the hardware and software revision levels of the CMTS 1000 mother board in the LCD status line. System Temperature The System Temperature parameter: displayed, System Temp, shows the rounded-up temperature in both Fahrenheit and Celsius scales.

It also dis- plays the center frequency of the channel in megahertz. Note: Only valid center frequencies from the North American Frequency Plan are accept- able.
Page 105 Up Stream State The Upstream State parameter: displayed, UpStm State, shows the Port state for up to eight ports of Upstream data, one port at a time. Indication per port includes Port Number (P1 through P8) and State (Up, Down, and ReqSvc).
Page 106: Cmts 1000 Snmp Mib Variable Descriptions
CMTS 1000 Installation Manual V1.2 CMTS 1000 SNMP MIB Variable Descriptions The CMTS 1000 is fully SNMP manageable. Table 4-2 shows the SNMP standard, impending standard, and enterprise specific Management Infor- mation Base (MIBs) groups that the CMTS 1000 support.
Page 107: Simple Network Management Protocol (Snmp) Overview
All of the SNMP management functions are carried out through these sim- ple operations. No action operations are available, but these can be simu- lated by the setting of flag variables. For example, to reset the CMTS 1000, an integer variable named “docsdevresetnow” is set to a specific value to reset the CMTS 1000.

Introduction The CMTS 1000 use the Trivial File Transfer Protocol (TFTP) to perform software upgrades. The following sections describe how to upgrade Bay Network’s Cable Modem and Cable Modem Termination System run-time software. Bay Network’s CMTS 1000 can be upgraded manually using an SNMP manager, both on-line and off-line.
Page 236: Upgrade Recommendations
CMTS 1000 Installation Manual V1.2 Upgrade Recommendations • Read software upgrade “readme” file for latest released software upgrade information. • Use a standard Simple Network Management Protocol (SNMP) manage- ment station such as CastleRock’s SNMPc™. • Have the network manager and TFTP file server residing on the same •...
Page 237: Preliminary Upgrade Steps
A multithreaded server should be limited to 25 units per upgrade session. Upgrade Procedure There are six basic steps to perform an upgrade to a CMTS 1000 using a standard SNMP manager. Verify contents of upgrade package.
Page 238: Step #1: Verify Contents Of Upgrade Package
CMTS 1000 Installation Manual V1.2 Step #1: Verify Contents of Upgrade Package The distribution method for the CMTS 1000 upgrade is via a Bay Net- work-maintained FTP server and web site. Upgrade software directories will include separate software files for the CMTS 1000. All pertinent SNMP MIB files are also included.
Page 239: Step #3: Ensure Devices Can Communicate With The Tftp Server
Press the Set button. The cable modem or Cable Modem Termination System will reset. Using the TFTP server’s visual display, ensure that the cable modem device is served its configuration file. 302693-B Rev 00 Modifying and Upgrading the CMTS 1000...
Page 240: Step #4: Initiate Upgrade Process
CMTS 1000 Installation Manual V1.2 Step #4: Initiate Upgrade Process Software Upgrade via SNMP Use the following procedure to upgrade a CMTS 1000 using an SNMP manager. Select cable modem device to be upgraded. Select the DocsDev MIB Object ID.
Page 241: Software Upgrade Via The Lcn Provisioning Server's Automatic Software Upgrade
Return to Step #2 and verify that the TFTP server is running and set up as discussed. The auto upgrade process begins upon a reset of the CMTS 1000. You can monitor the process if your TFTP server has a display window or returns status information to you.
