3.6 OnSite DSL Commands
CO and CPE:
This will set the EFM Router as CO or CPE. CO is typically used at the network, CPE is typically
used at the CPE device or CPE network.
node(prt-DSL)# mode {CO|CPE}
Annex Type:
Please consult support before changing this setting.
node~(prt-DSL)[<name>]# annex-type { b-g | a-f }
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 man-
ual 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>
