Default Access Level

Command Syntax

<int>
Supplemental
Information
This contains the maximum amount of time in microseconds that it would take a cable modem to send a message, such as a
broadcast ranging attempt, to the C4 CMTS and to receive a response.
This parameter is used to determine the amount of time that must be given to a cable modem to transmit broadcast ranging
messages. The parameter is also used to determine the needed Map Ahead Timer for DOCSIS® Map messages.
The default time is 1600 microseconds, which is roughly enough time for a cable modem up to 100 miles from the C4 CMTS to send
a message and receive the response.
Parameters
<slot>
The chassis slot in which the targeted downstream Cable Access Module resides. Valid range for the C4 CMTS is 0-15; valid range for
the C4c CMTS is 10-15.
<port>
The downstream port.
<int>
Defines the maximum round trip propagation delay for the cable plant. Valid range is from 200-1600 microseconds.
Default is set at 1600 microseconds
