Each SCB/SXB pair can connect up to 4 ISL but it is recommended to only use two ports on each SCB/SXB pair in order to get the maximum available bandwidth out of each ISL (~ 600 Mbps total bandwidth on one SCB/SXB output). The ISL is a redundant bus active + standby. SCB’s and SXB’s work in pair, one active and one standby. The maximum node size is 6 subracks (one main and 5 extension). Node Type A B C D E F Nr of Subracks 1 2 3 4 5 6 Example RNC: An RNC F-node cabinet with one main subrack and 5 extension subracks. The first two extension subracks connect into the SCB pair of the main surbrack. The next three extension subracks connect into one SXB pair. Each SCB/SXB has a total capacity of 600 Mbps. Extension Subracks 1 and 2 are connected to SCB 0/1. ISL-1 and ISL-2 have capacity of 300 Mbps Extension Subracks 3, 4, 5 are connected to SXB 2/3. ISL-3,4,5 have capacity of 200 Mbps (Note: in MGW, 4 ISL are used for each extension subrack, giving a bandwidth of 1.2 Gbps) Finn Magnusson 2010-03-17 rev PA8 218/524)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
