SXB is not present in RNC 3820

An RNC always includes an MS. The MS interconnects all other subracks in theRNC and includes all functions of an ES as well as functions common to the RNC

Other changes

TUB's have been moved to slots 2 and 27 in Main Subrack ESL carries user plane traffic between subracksCMXB & ET-IPG replaces ET-MFG. CMXB & ET-IPG connect through the Ethernet switchboard (ESL) on the back plane. ET-IPG in MS can be used for Iu-Cp & Iu-Up termination (refer to MO Structure). ET-IPG in ES-1 & ES-2 can be used for Iu-Up termination, but not Iu-Cp (refer to MO Structure).

SCB - DFSwitch core board - dual feed

• Provides switch functionality (interface toward the switch core).• Distributes system synchronization.• Provides the ISL interfaces for connection between subracks.• Provides power to the subrack, and in some cases to the fan unit.• Controls the nearest CMXB, if present in the subrack. If an SCB-DF isfaulty or is removed from the subrack, the nearest CMXB ceases to workwithin 90 seconds.

CMXBCommon Main Switching Board

The CMXB is a 20-port 10G BASE-CX4 Ethernet Switch that provides eightfront-panel electrical Ethernet ports for user-plane data to and from the subrack,and 12 backplane Ethernet ports for device boards in a subrack.

provides 10G BASE-CX4 connectivity for internal and externaluser-plane traffic with redundancy between device boards in the same ordifferent subracks.

The board is controlled (Ethernet and Reset) by the adjacent Switch ControlBoard - Dual Feed (SCB-DF) through a point-to-point 1G Ethernet SerDesInterface (MMEL)

Advantages

›Iu and Iur user plane can now be terminated in extension subracks ES-1 and ES-2. ›Inter-subrack user plane capacity increased with 10 Gb/s ESL (Ethernet Subrack Link) connections. ›New SCB-DF (Switch Core Board Dual Feed) power supply. ›RNC 3820 introduces 10 Gb Ethernet on external physical interface (Iu, Iur, Iub) via CMXB and APP (Active Patch Panel). ›Supports interface types 10G BaseT and Optical (via SFP modules) ›New RNC Module Identity (rncModule) based on subrack and slot position. ›Introduces new black box configuration when adding an IP based RBS. The operator does not need to define a referred subrack.
