MRMC Symmetrical Scripts Page Parameters
Parameter
Definition
Script ID
A unique ID assigned to the script in the system.
Channel Bandwidth (MHz)
The script's channel bandwidth (channel spacing).
Occupied Bandwidth (MHz)
The script's occupied bandwidth.
Script Name
The name of the script.
ACM Support
Indicates whether the script supports ACM. All PTP 850E scripts support
ACM.
Supported QAM
MRMC Symmetrical Scripts Main Page only: Displays the range of modulation
levels, in QAM, supported by the script.
Bit Rate (Mbps)
MRMC Symmetrical Scripts Main Page only: Displays the range of bit rates, in
Mbps, supported by the script.
Symmetry
MRMC Symmetrical Scripts Configuration Page only: Indicates that the script
is symmetrical (Normal). Only symmetrical scripts are supported in the
current release.
Standard
MRMC Symmetrical Scripts Configuration Page only: Indicates whether the
script is compatible with ETSI or FCC (ANSI) standards, or both.
MRMC Script operational mode
MRMC Symmetrical Scripts Configuration Page only: The ACM mode:
Fixed
or
Adaptive
.
•
Fixed ACM mode applies constant TX and RX rates. However, unlike regular
scripts, with a Fixed ACM script you can specify a maximum profile to inhibit
inefficient transmission levels.
•
In Adaptive ACM mode, TX and RX rates are dynamic. An ACM-enabled radio
system automatically chooses which profile to use according to the channel fading
conditions.
MRMC Script profile
MRMC Symmetrical Scripts Configuration Page, Fixed ACM mode only: The
profile in which the system will operate.
MRMC Script maximum profile
MRMC Symmetrical Scripts Configuration Page, Adaptive ACM mode only:
The maximum profile for the script. For example, if you select a maximum
profile of 5, the system will not climb above profile 5, even if channel fading
conditions allow it.
MRMC Script minimum profile
MRMC Symmetrical Scripts Configuration Page, Adaptive ACM mode only:
The minimum profile for the script. For example, if you select a minimum
profile of 3, the system will not go below profile 3 regardless of the channel
fading conditions. The minimum profile cannot be greater than the maximum
profile, but it can be equal to it.
Note:
The default minimum profile is 2.
