When configuring an unchannelized SONET/SDH interface, you first configure ATM or
POS on the interface. For details on configuring POS and ATM, see Configuring ATM and
Configuring packet over SONET in JunosE Link Layer Configuration Guide,
On an OCx/STMx/DS3-ATM line module with an OC3-4 or OC12 I/O module, you can
configure only ATM interfaces.
On an OCx/STMx POS line module with an OC3-4 or OC12 I/O module, you can
configure only POS interfaces.
On an OC48 line module with an OC48 FRAME I/O module, you can configure only
POS interfaces.
On an OC3/STM1 GE/FE line module with an OC3-2 GE APS I/O module, you can
configure only ATM interfaces on ports 0 and 1.
On an ES2 4G LM with an ES2-S1 OC12-2 STM4 POS IOA or an ES2-S1 OC48 STM16
POS IOA, you can configure only POS interfaces.
On an ES2 4G LM with an ES2-S1 OC3-8 STM1 ATM IOA or an ES2-S1 OC12-2 STM4
ATM IOA, you can configure only ATM interfaces.
When you configure ATM or POS on an interface, you automatically configure default
settings at the SONET/SDH layer. To modify the default settings:
Select an interface on which you want to configure SONET or SDH.
1.
Specify the type of interface: SONET or SDH.
2.
Specify a clock source for the interface.
3.
(Optional) Assign a text description or an alias to the interface.
4.
Disable processing of SNMP link status information for the section and line layers
5.
of the interface.
Enable processing of SNMP link status information for the path layer of the interface.
6.
(Not recommended) Overwrite the automatic setting for the path signal label (C2)

waits to set an alarm when the router records a defect at the line or section layer.
Shut down (disable) an interface.
