Emulation is a mechanism that duplicates the essential attributes of a service (such as
T1 or E1) over a packet-switched network. You set the emulation mode so that the built-in
channelized T1 and E1 interfaces on the ACX Series router can be configured to work in
either T1 or E1 mode. This configuration is at the PIC level, so all ports operate as either
T1 interfaces or E1 interfaces. A mix of T1 and E1 interfaces is not supported. By default
all the ports operate as T1 interfaces.
Configure the emulation mode:
[edit chassis fpc fpc-slot pic pic-slot]
user@host# set framing (t1 | e1)
For example:
[edit chassis fpc 0 pic 0]
user@host# set framing t1
After a PIC is brought online and depending on the framing option used (
the ACX2000 router, 16 CT1 or 16 CE1 interfaces are created, and on the ACX1000
router, 8 CT1 or 8 CE1 interfaces are created.
The following output shows this configuration:
user@host# show chassis
fpc 0 {
pic 0 {
framing t1;
}
}
The following output from the
interfaces created with the framing configuration.
user@host# run show interfaces terse
