Firstly, you need to be aware that there was a 100G version of the E320, which can be upgraded to a full 320G E320 by replacing the five central SRP/SF modules. There is also an E120 in the series (basically a half size E320, with blades mounted horizontally)
I am assuming that you have (or are investigating) the E320 with 320G fabric, so as per:-
http://www.juniper.net/techpubs/hardware/erx/junose91/hw-e120-e320-module-guide/lm-10-uplink-line-module.html#lm-10-uplink
- The 100–Gbps switch fabric allocates 3.4 Gbps of overall bandwidth to each regular line module slot and 10 Gbps of overall bandwidth to each of the turbo slots (slot 2 and slot 4).
- The 120–Gbps and 320–Gbps switch fabrics allocate 10 Gbps of overall bandwidth to each line module slot.
- See JUNOSe System Basics Configuration Guide, Chapter 6, Managing Modules for more information.
