Installation Instructions
Integration and Test, RBS 884 Pico (850 MHz and 1900 MHz)
5.6.4.3 Eleven EMRPS: Pico 850 MHz
An 11-EMRPS Pico 850 MHz configuration uses 3 XLI boards. There is
a maximum of 11 EMRPS slots in the CRI subrack. This configuration
requires 3 XLI boards that provide link access for 11 Radio Heads. This
configuration also requires 2 ETB24 or 2 ETB32 boards if the full traff
ic
capacity of the cells is used. The CRI subrack layout for this configuration is
shown in Figure 5-9 on page 5-42.

5.6.4.4 Three EMRPS: Pico 1900 MHz
Athree-EMRPSPico 1900 MHz configuration uses one ELI board,
regardless of the channel functions provided, since there is a one-to-one
correspondence in the number
of EMRPS boards and Radio Heads. One
ETB board is used and may be either a 24 time-slot T1 version or a 32
time-slot E1 version. The CRI subrack layout for this configuration is
shown in Figure 5-10 on
page 5-43.
