OnSite OS3300 Quick Start Guide
DSL Rate Configuration:
This will increase the DSL rate of the OS3300. Your OnSite
3300 is defaulted to automatically select the optimal rate based on the distance (adaptive).
node(prt-DSL)[0/0]# payload-rate {adaptive [max
<192..15296>] | <192..15296>}
Modulation Scheme:
Note higher TC-PAM rates will increase maximum payload rates
available but will decrease distance. Your OnSite 3300 is defaulted to automatically
select the optimal setting. Please consult manual for the rate reach chart to determine
your optimal setting if you choose to hard set this value. Higher TC-PAM rates are ideal
for shorter cable runs offering max symmetrical (upstream/downstream) speeds of
11.4 Mbps (TCPAM64) and 15.3 Mbps (TCPAM128) per pair.
node(prt-DSL)[0/0]# tcpam {auto(16/32) | auto(64/128) | 16
| 32 | 64 | 128}
OnSite Ports:
The configurations below are used to configure various aspects of the
OnSite port(s):
node~(prt-DSL)# port dsl 0 0
Signal to Noise Ratio:
Configures the acceptable noise margin for adaptive rate. SNR
is the relative strength of the DSL signal to Noise ratio. 6dB is generally the lowest dB
recommended in order for the modem to synch. As overall bandwidth increases, your
signal to noise ratio decreases; the higher the number the better. Your OS3300 is
defaulted at 6 giving you the highest likelihood to connect.
node(prt-DSL)[0/0]# snr-margin <-10..22>
Description:
This is the description of the port/DSL (OnSite connection). (Ex: "This
DSL goes to building 4") When entering a description with spaces in the text, the
description must be in quotations.
node~(prt-DSL)[0/0]# description <description>
Use Profile:
Configures the acceptable noise margin for adaptive rate. SNR is the rela-
tive strength of the DSL signal to Noise ratio. 6dB is generally the lowest dB recom-
mended in order for the modem to synch.
node~(prt-dsl)[0/0]# use profile <name>
Service Mode:
Configures the number of pairs (wires) you want to use. The OS3300
will default to the maximum number of wires available on your version of the OnSite.
OS3301 (2-wire); OS3302 (4-wire); OS3304 (8-wire).
node~(prt-DSL)[0/0]# service-mode { 2-wire | 4-wire | 6-
wire | 8-wire }
