Adding a Modem to the XMTS – p. 35
2. DHCP Settings for the Modem explains how to set (bind) the
modem’s IP address and configuration file using either ipLease or the
Windows 200x Server Edition DHCP Server.
3. Configuring the XMTS describes how to configure the XMTS
upstream, downstream and QoS parameters. At this time instructions are
provided for using the Vyyo Configuration tool. Older systems use the
Castlerock NMS SNMPc Version 5 Synoptic display interface to change
XMTS parameters. Equivalent instructions for performing these changes
are shown in Configuring the XMTS
4. Setting the Modem’s Downstream FrequencySetting the Modem’s
Downstream Frequency describes how to set the modem downstream
initial receive frequency via the modem’s internal Telnet server.
5. Maintenance and Troubleshooting describes how to use the
modem’s internal Telnet server to view the modem’s downstream and
upstream status (current values) and verify correct operation.
5.1 Editing the Modem Configuration File
You will need to edit the modem configuration file to set the XMTS downstream
frequency, upstream channel ID, concatenation and fragmentation capabilities, and
QoS. This file will be downloaded to the modem during its initialization sequence.
NOTE: A separate modem configuration file is required
for each set of upstream and downstream channels. Any
modem may use any configuration file and the same file
may be used by many modems; typically only five T1
modems are assigned to a single 3.2MHz upstream
channel.
5.1.1 Setting the Upstream Channel
Open the WMUconfigFileEditor to edit the modem configuration file to set the
Downstream Frequency and Upstream Channel ID.
Note: If using ipLease, the modem configuration file is
bound to the modem’s MAC address in the CM.SRC file.
If using Windows 200x Server Edition bring up the DHCP
Administrative Tool to find the configuration file to the
mode:
Programs->Administrative Tools->DHCP
