xviii ChannelWorks Network Installer’s Guide
Known Problems
The following items are under investigation:
1. The ChannelWorks Bridge operation has been verified at frequencies corresponding to standard NCTA channel assignments. For optimal receiver operation avoid
using the following forward (RX) frequencies:
• 79.000 MHz
• 85.000
• 93.000
• 105.000
• 141.000
• 429.000
• 465.000 MHz
2. The LANcity Management Utility (LCM) prevents the user from entering illegal
and non-optimized Max Round Trip Delay values. However, the ChannelWorks
Bridge software does not prevent the user from entering less than optimal Max
Round Trip Delay value when performing SNMP “sets” on the enterprise specific
MIB variable lcmaxrndtripdel in the ASIC Parameters group.
3. The Support History Log does not consider an error code at two different error levels as unique, which could be misleading as in the following example:
If error 0x35 is logged as a level 2 and at a later time error id 0x35 is logged at a
level 4, when displaying the Support History Log the second error as shows as a
level 2 crash.
4. The LANcity Subscriber Utility (LCS) and the LCM do not operate properly on a
66 MHz PC.
5. The PROM Monitor’s printcfg command displays an incorrect software version
value under the “Vers” heading. The “Description” heading displays the correct
software version. You can also use the SNMP enterprise specific MIB variable
lcsoftware in the Revision Levels group to view the correct software version.
6. Counters from the interface group of the MIB-II are not implemented correctly for
the serial port.
7. The IPNetT oMediaTable and the atT able of MIB-II cannot be modified via SNMP.
The enterprise specific MIB variables lcmcastrx and lcbcastrx from the Sonic Stats
group are not implemented.

Introduction
This manual explains how to install the ChannelWorks Bridge, a 10 Mb/s, Ethernet-tocable TV, transparent, spanning-tree bridge. This chapter covers the following topics:
• Tasks that need to be completed before beginning installation
• Tools necessary for installation
• How to tell that the cable TV network is certified for data delivery
Pre-Installation Tasks
This manual assumes that you have completed the following tasks:
1
Introduction
• The cable TV network has been prepared to communicate with the unit, that is,
certified for data delivery.
• The unit has already been configured with the correct receive and transmit frequencies for this network. The installation materials that are shipped with this
manual allow you to verify them but not to change them. If you need to change
them, you must have the ChannelWorks Cable TV Installer's Guide and authorized
software. Refer to Chapter 3, “Set-Up and First Steps,” for procedures to verify
preconfigured installation parameters.
1-1
Required Tools And Materials
• A 7/16-in open end wrench for attaching the cable TV cable to the unit.
• If you are going to be verifying the units’ installation parameters, a PC running
Windows 3.1, a terminal emulator , and a nine-pin null-modem cable to connect the
PC’s serial port with the bridge’s serial port
• For single-cable, cable TV networks, a subsplit, midsplit or highsplit diplex filter
(separately orderable item), if one is not already installed at the site; you will also
need short (18-in) attachment cables (RG6) (separately orderable) for the receive
and transmit ports of the diplex filters.
• Network connection cables (both cable TV and Ethernet networks).
• If the unit is being rack-mounted or wall-mounted, the Channelworks Bridge Rack
Mount or Wall Mount Kits (separately orderable), and the required mounting hardware (listed with the mounting instructions).
How To Tell If The Cable TV Network Is Ready
Before beginning installation of the unit, verify that the cable TV system meets the following criteria, and is ready to accept the unit. Check with the cable installer or cable
system owner if necessary:
• The system must be two-way active, and must be capable of carrying signals from
the unit inbound to the headend, as well as out-bound from the headend to the unit.
• The signal path must meet conditions as specified in the ChannelWorks Cable TV
Installer’s Guide and documented for your specific installation site in the PreInstallation Checklist. A sample Pre-Installation Checklist is provided in the
Appendix B.
• On single-cable systems, there must be a translator installed at the headend, operating at the correct transmit and receive frequencies.
Before installing the unit, verify that the transmit and receive frequencies that have
been assigned to the unit are correct. If the unit is set to the wrong frequencies, it will
not operate on the network, and could also disrupt other users of the cable TV system.
