By default, SONET/SDH PICs operate in concatenated mode. To specify interface
speed in concatenated mode, include the
interfaces so-fpc/pic/port]
For example, each port of the 4-port OC12 PIC can be configured to be in OC3 or
OC12 speed independently when this PIC is in 4xOC12 concatenated mode.
To specify interface speed in nonconcatenated mode, include the

Configuring Keepalives

By default, physical interfaces configured with Cisco HDLC or PPP encapsulation
send keepalive packets at 10-second intervals. The Frame Relay term for keepalives
is LMI packets; the JUNOS Software supports both ANSI T1.617 Annex D LMIs and
ITU Q933 Annex A LMIs. On ATM networks, OAM cells perform the same function.
You configure OAM cells at the logical interface level; for more information, see
"Defining the ATM OAM F5 Loopback Cell Period" on page 337.
To disable the sending of keepalives on a physical interface, include the

To disable the sending of keepalives on a physical interface configured with Cisco
HDLC encapsulation for a translational cross-connection, include the
