|
Configures a
fixed frequency of the upstream RF carrier for an upstream port.
- n—Specifies the upstream port number on the
Cisco uBR-MC3GX60V-RPHY line card. The valid range starts
with 0 for the first upstream port on the line card.
- up-freq-hz—Upstream center frequency in Hz. The
valid range is from 5 MHz (5000000 Hz) to 85 MHz (85000000 Hz).
|

upstream
max-ports

|
Step 8 | cable

port
connector
physical-port
Example:
Router(config-if)# cable upstream 2 connector 0
|
Maps an
upstream port to a physical port on the
Cisco uBR-MC3GX60V-RPHY line card for use with a downstream.
|
Step 9 |
cable
upstream
n
docsis-mode
{atdma
|
tdma
}
Example:
Router(config-if)# cable upstream 2 docsis-mode tdma
|
Configures an
upstream channel to use either DOCSIS 1.x or DOCSIS 2.0 modulation profiles.
-
n—Upstream port number. The valid values start
with 0 for the first upstream port on the
Cisco uBR-MC3GX60V-RPHY line card.
-
atdma
—Configures the upstream only for the DOCSIS
2.0 Advanced Time Division Multiple Access (A-TDMA) modulation profiles.
-
tdma—Configures the upstream only for the DOCSIS
1.0 and DOCSIS 1.1 Time Division Multiple Access (TDMA) modulation profiles
(default).

Step 10 | cable
upstream
n
channel-width
first-choice-width
[last-choice-width]
Example:
Router(config-if)# cable upstream 2 channel-width 1600000 1600000
| Specifies an
upstream channel width for an upstream port.
-
n—Upstream port number. The valid values start
with 0 for the first upstream port on the
Cisco uBR-MC3GX60V-RPHY line card.
-
first-choice-width—Upstream channel width, in Hz.
The valid values for all cards are:
-
200,000 (160,000 symbols/sec)—Not valid when using Unsolicited
Grant Service (UGS) or UGS with Activity Detection (UGS-AD) service flows (such
as PacketCable voice calls).
-
400,000 (320,000 symbols/sec)
- 800,000 (640,000
symbols/sec)
- 1,600,000 (1,280,000
symbols/sec)
- 3,200,000 (2,560,000
symbols/sec)
-
last-choice-width—Upstream channel width, in Hz.
The valid values are the same as those for the first-choice-width parameter,
but for proper operation, the
last-choice-width should be equal to or less than
the
first-choice-width value. Use this parameter with
supported cards to enable symbol rate management algorithms. The symbol rate
automatically steps up from the
first-choice-width value to the highest value
until a stable channel is established.

with 0 for the first upstream port on the
Cisco uBR-MC3GX60V-RPHY line card.

Assigns one or
two modulation profiles to an upstream port.

with 0 for the first upstream port on the
Cisco uBR-MC3GX60V-RPHY line card.
-
primary-profile-number—Primary modulation profile

-
secondary-profile-number—Secondary modulation
profile number for the upstream port, which is used when noise on the upstream

used. The valid range is same as the range for the
