Figure 6: T3 Interface Configuration Parameters
The following sample command sequence configures a serial interface for a T3
module. See JUNOSe Physical Layer Configuration Guide, for details.
host1(config)#controller t3 0/1
host1(config-controll)#framing m23
host1(config-controll)#cablelength 300
host1(config-controll)#ds3-scramble
host1(config-controll)#exit
host1(config)#interface serial 0/1
host1(config-if)#invert data
host1(config-if)#mtu 1600
host1(config-if)#mru 1600
Configuring OCx/STMx and OC48 Interfaces
The router supports IP/ATM, IP/Frame Relay, and IP/PPP over SONET on the
OCx/STMx interfaces. OC48 interfaces support IP/Frame Relay and IP/PPP over
SONET, but do not support ATM operation. This interface support allows service
providers to accept incoming optical connections or connect the router to the
backbone network through optical connections. The router’s SONET implementation
supports termination, statistic gathering, and alarm surveillance at the section, line,
and path layers of a SONET interface.
Figure 7: SONET Interfaces
The following sample command sequence configures POS for an OC3 interface. See
JUNOSe Link Layer Configuration Guide, for details.
host1(config)#interface pos 0/1
host1(config-if)#encapsulation ppp
host1(config-if)#clock source internal module
host1(config-if)#loopback line
