Table 1-1. APOI Modules Descriptions
BTSI MODULES
DESCRIPTION
BTSI RF
Interfaces
Up to eight hot-swappable band-specific conditioning modules that provides BTS to
MTDI
interfaces. Each module supports two same-band channels of up to 30dBm.
x
BTS side – simplex and duplex connections
x
MTDI side – simplex only.
x
RF interfaces – four QMA female connectors per sector: two BTS and two MTDI.
x BTS connections per sector – UL/DL QMA is a double purpose port used for BTS
UL simplex connections and for BTS duplex connections
x
For single converged output (software configured), only the top sector interfaces
are connected. Combined sectors are of the same band but cannot be the same
frequencies.
BTSI Module LEDs
DL Input
Status of input from the RF source:
x
Green – normal operation
x
Orange – BTS power is lower than valid minimum input
power
x
Orange blinking – either in Test mode or RF is OFF
DL Output 1/2
Status of output towards BTS:
x Green – normal operation
x
Red (steady or blinking) – Major fault
The output power from either channel exceeds
the power
limit set in Manual mode.
x
Orange linking – either in Test mode or RF is OFF
CONTROL
MODULE
DESCRIPTION
Control Module
Interfaces and
LEDs
x
Implements the APOI control and management capabilities.
x
The Control module Eth port must be connected to (any) one of the Ethernet
ports on the Display and Switch module.
x
CCD status LED – Green blinking indicates normal operation.
DISPLAY AND
SWITCH MODULE
DESCRIPTION
Display and
Switch
Module
Interfaces
x
Provides identification, as well and management connection to MTDI.
x RJ-45 ports – four identical ports
One of the ports is connected to the Control module Eth port, and another to
the APOI MNG port on the relevant MTDI unit.
