Configuring The S-Cdma Hopping Seed; Configuring The S-Cdma Spreading Interval; Displaying The Upstream Logical Channel Configuration - Motorola BSR 2000 Configuration And Management Manual

Release 1.0

Configuring the S-CDMA Hopping Seed

Use the cable upstream hopping-seed command, in Cable Interface Configuration
mode, to specify the 15 bit S-CDMA hopping seed value used for the code hopping
sequence initialization, as shown below:
MOT(config-if)#cable upstream <X/Y> hopping-seed <0-32767>
where:
Note: The logical channel must be disabled to specify a new hopping seed
value.

Configuring the S-CDMA Spreading Interval

S-CDMA channels support the configuration of spreading interval. A spreading
interval is the time that it takes to transmit one symbol per code across all 128 codes
in an S-CDMA frame. The time duration of an S-CDMA frame is determined by a
configurable number of spreading intervals and the signaling rate.
Use the cable upstream spread-interval command, in Cable Interface Configuration
mode, to specify the spreading interval for an S-CDMA frame, as shown below:
MOT(config-if)#cable upstream <X/Y> spread-interval <1-32>
where:

Displaying the Upstream Logical Channel Configuration

Use the show cable upstream command, in Cable Interface Configuration mode, to
display the complete configuration of an upstream logical channel, as shown below:
526360-001-00 Rev. B
X/Y is the upstream port and logical channel number (0-3).
2-32 is the number of codes allowed per minislot.
X/Y is the upstream port and logical channel number (0-3).
0-32767 is the hopping seed value (0 disables code hopping)
X/Y is the upstream port and logical channel number (0-3).
1-32 is the spreading interval value.
MOT(config-if)#show cable upstream {<NUM> | <X/Y>}
