Configuring ATM Mode for SHDSL Overview

To configure the ATM mode for SHDSL, include the pic-mode statement at the [edit chassis fpc fpc-number pic 0 shdsl] hierarchy level:



[edit chassis]
fpc fpc-number {


pic 0 {


shdsl {
pic-mode (1-port-atm | 2-port-atm);
}


}


}

For more information about configuring the ATM mode, see the JUNOS System Basics Configuration Guide and the J-series Services Router Advanced WAN Access Configuration Guide.

To configure SHDSL operating mode on the physical ATM interface and set the encapsulation, include the shdsl-options statement and the encapsulation statement at the [edit interfaces at-pim/0/ port] hierarchy level:



[edit interfaces at-pim/0/port]

shdsl-options {

annex (annex-a | annex-b);

line-rate line-rate;

loopback (local remote);



snr-margin {

current margin;

snext margin;
}


encapsulation (atm-pvc | ethernet-over-atm)
}

To configure ATM virtual path identifier (VPI) options for the interface, include the vpi statement at the [edit interfaces interface-name atm-options] hierarchy level:



[edit interfaces interface-name] 
atm-options {



vpi vpi-identifier {

maximum-vcs maximum-vcs;



oam-liveness {
up-count cells;
down-count cells;
}



oam-period (disable | seconds);
}


}

For more information about configuring ATM VPI options, see Configuring the Maximum Number of ATM1 VCs on a VP.

To configure logical interface properties, include the encapsulation statement, family statement, and vci statement:




unit logical-unit-number {

encapsulation type;



family inet {

vci vpi-identifier.vci-identifier;
}


}

You can include these statements at the following hierarchy levels:

[edit interfaces interface-name unit logical-unit-number]
[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]
