SGP+M is a system developed by Landis+Gyr and running in Brazil (and potentially other countries), it stands for Sistema de Gestão de Perdas e Medição (System for Management of Losses and Metering). It is divided into Primary Concentrators (Concentrador Primário or CP) and Secondary Concentrators (Concentrador Secundário or CS).
Note that I don't access to the hardware described here. All of my research was done through observation and research.

Known Operating Locations
- Rio de Janeiro, Brazil
Metering Module
The Metering Module (Módulo de Medição) is installed inside the CS, each utility client has one dedicated to them (or 2/3 if they have a two-phase or three-phase system).
This module has a built-in smart meter system, contactor for remote shutdown, and a phototransmitter and photoreceiver for communication with the CS computer.
Secondary Concentrator
The Secondary Concentrator houses 12 Metering Modules, a CPU/Radio (metal box on the right) and a main MCCB. The Metering Modules talk with the CPU through a shared optical interface. The CPU contains the software/harwdare to communicate with each meter and a built in radio that communicates with the PC through some proprietary FHSS stuff briefly mentioned in the manual.
Primary Concentrator
The Primary Concentratoris the heart of the system. Primary and Secondary concentrators look identical from the outside (besides the fact that the PC has less wires coming out because there are no metering modules).
The PC holds inside a computer that I assume is way stronger, a radio to communicate with all the SCs around and a GPRS radio to inform power usage data to the power company.
TLI (i actually have two of these)
The TLI (Terminal de Leitura Inteligente) stands for Smart Reading Terminal. It's a RX only device that displays power usage information. Since the meter is on top of the pole, this device is the way for the client to know how much power is being used, and for manually reading in case the wide network ever goes down. It contains a Z8F0421 microcontroller, ATA5744N RF RX IC, and a CF8566T LCD driver.
It has a 6 pin debug header (but DBG is locked from factory, it must be unlocked through Z8 Encore BYPASS mode, info on that soon)
1 - DBG
2 - MAIN_PWR (Capacitive dropper output)
3 - 3V3_PWR (regulated output, MCU power)
4 - NC
5 - NC
6 - GND
