2 Line Unit (LU1)
2.1
Overview
LU1 is a single-slot unit designed for networks requiring high switching capacity and multiple high
speed Ethernet interfaces for enabling smooth technology and capacity migration driven by HSPA
and LTE growth. The main applications of LU1 are MPLS trunking over the 10/100-Gigabit Ethernet
links in mesh or ring topology, and IP or IP VPN service endpoint, for example at the RNC site.
LU1 combines 130 Gbp/s with a single operational SU1 and 200 Gbp/s with two operational SU1s
switching capacity, and two operating modes with the following port con
fi
guration options at
wire speed:
• 1x100GBASE-R (CFP2) + 14x1/10GBASE-R (SFP+/SFP)
• 24x1000BASE-X/10GBASE-R (SFP+/SFP)
As not all the ports can be used at the same time, one of the supported modes has to be selected. For
more information on the operating modes, see chapter
2.4 Interfaces
.
As all the other 8600 cards, LU1 is hot-swappable.
The maximum con
fi
guration of six LU1 can be achieved either with one or two 8665 Smart Router
DC48 power input modules in the 8665 Smart Router subrack.
Each LU1 has a direct connection via the backplane to both switch units in 8665 Smart Router.
