A bandwidth of up to 340 Gbps per slot with redundant fabric support and 480 Gbps
per slot without redundancy, and improved fabric performance on account of using
the next-generation fabric (XF2) chip.
A central clocking module and a centralized clocking architecture that support clock
cleanup and distribution. The Stratum 3 clock module performs clock monitoring,
filtering, and holdover at a centralized chassis location.
Full performance with fabric redundancy for higher-capacity line cards such as MPC4.
Support for MPC line cards only
Two 10-Gigabit Ethernet SFP+ ports. SFP+ port 0 can be used to connect an external
device as a Route Reflector. SFP+ port 1 is unused.
Support for cross-coupling of clock input (which requires an enhanced midplane:
CHAS-BP3-MX240-S). You can configure the system such that one SCBE2 supports
a GPS interface, and the other SCBE2 supports a BITS interface.
The Routing Engine is installed directly into a slot on the SCBE2 (see

Figure 38: SCBE2

You can install either one or two SCBE2s. SCBE2s are installed horizontally into the front
of the chassis in the slots labeled
panel.
