Installation Instructions

Integration and Test, RBS 884 Pico (850 MHz and 1900 MHz)
5.2.4.1 ETB24 Board: 850/1900 MHz
The first ETB24 board (T1 connection) supports 24 time slots (0–23) with 1
time slot reserved for the Extension Module Group (EMG) control.
The second ETB24 board (T1 connection) supports 24 time slots, and does
not require the EMG control time slot. Using a second ETB24 board provid
es
a total of 47 time slots between the two T1s that can be assigned to TRXs.
5.2.4.2 ETB32 Board: 850/1900 MHz
The first ETB32 board (E1 connection) supports 32 time slots (0–31)
with 1 time slot reserved for EMG control and 1 time slot reserved for
synchronization.
The second ETB32 board (E1 connection) supports 32 time slots. The
second ETB32 board requires a synchronization time slot, but does not
require an EMG control time slot. Using a second ETB
32 board provides a
total of 61 time slots between the two E1s that can be assigned to TRXs.
5.2.5 EMRPS Provisioning Guidelines: Pico 850/1900 MHz
The EMRPS boards in the CRI provide the logical part of the channel
functions.
The Pico 850 MHz CRI can contain a maximum of 11 EMRPS boards.
The Pico 1900 MHz CRI can contain a maximum of 10 EMRPS boards.
The channel assignment functions for t
he EMRPS are performed manually
and are very flexible. The allocation of channel functions are such that one
EMRPS provides the channel functions for one Radio Head.
For additional information abo
ut EMRPS load distribution, see Section 5.7
on page 5-44.
5.3 Routes Configuration: Pico 850/1900 MHz
Routes are a means of grouping d
evices together that provide common
functions. There are five types of routes used for base station related
equipment:
• Signaling Routes (SI/SO)
• Voice Line Routes
