The story of the "Ericsson Elex Top" likely refers to two distinct but foundational components of Ericsson's telecommunications history: the documentation system and the programming language , both of which are critical to the success of the switching system. The AXE System: The Foundation AXE (Automatic Exchange Electric)
system was a revolutionary digital switching platform developed in the 1970s. It transformed Ericsson from a mechanical manufacturer into a global electronics giant. Key Technical "Elex" Components Advanced Radio Technology : The Elex Top utilizes
While there is no single product called "Elex Top," the term likely stems from these core Ericsson technologies: PLEX (Programming Language for Exchanges): Designed specifically for the AXE system,
is a proprietary, real-time, concurrent programming language.
It was built to handle the extreme reliability requirements of telephone exchanges, allowing software to be updated without stopping the system—a "top" tier capability for its time. ALEX (Active Library Explorer):
is Ericsson’s technical documentation and reference library.
It serves as the "top" resource for engineers, providing searchable, cross-referenced manuals and procedures for installing and maintaining AXE equipment. APZ (Application Processor Central):
The APZ is the high-performance central processing unit of the AXE-10 system.
It acts as the system's "top" controller, overseeing all operations and maintaining stability. The Business "Story"
In the early 1970s, Ericsson faced a "sink or swim" moment. They chose to abandon their AKE system and bet everything on the modular AXE architecture. This bet paid off enormously, as the AXE system became the world’s most advanced switching system, eventually capturing roughly 40% of the global mobile telephony market by the early 1990s. technical manuals from the ALEX system, or are you interested in how to program using PLEX? Development of the AXE system - Ericsson history
What Was the Ericsson Elex Top?
Launched in the early 1970s by the Swedish multinational Ericsson, the Elex Top (often stylized as ELEX-TOP) was a local telephone exchange designed for medium to large subscriber capacities. Unlike pure electromechanical systems that relied on physical moving parts (relays, selectors, magnets) for both control and switching, the Elex Top introduced a hybrid architecture:
- Control: Fully electronic, using stored-program control (SPC) based on discrete transistor logic (later TTL).
- Speech Path Switching: Analog, using high-quality reed relays sealed in glass capsules (dry reed switches).
This "electronic brain, analog body" approach offered a compelling upgrade path for telephone administrations in the 1970s and early 1980s.
1. Ham Radio & Amateur Radio Power Supply
The 13.8V required for most transceivers is tricky, but the 12V Elex Top can be tweaked up to 13.6V-13.8V using the internal trim pot. With 25A to 50A capability, it can easily drive a 100W HF transceiver. The low noise floor means you won't hear the supply on your receiver.
3. Distributed Peripherals
Unlike centralized systems, the Elex Top used regional processors (called "RAX" units in some documentation) to handle line scanning and tone generation. This reduced load on the central CPU and improved fault tolerance.
Typical Model Breakdown (Examples found in the field)
| Model Variant | Voltage | Capacity (Ah) @ 20hr rate | Typical Dimensions (LxWxH) | Common Use Case | |---------------|---------|---------------------------|----------------------------|------------------| | ELEX TOP 12-18 | 12V | 18 Ah | 181 x 76 x 167 mm | Small UPS, DSLAM | | ELEX TOP 12-26 | 12V | 26 Ah | 165 x 125 x 175 mm | Micro BTS, routers | | ELEX TOP 12-65 | 12V | 65 Ah | 350 x 166 x 174 mm | Street cabinets | | ELEX TOP 12-100| 12V | 100 Ah | 330 x 173 x 216 mm | Main BTS backup | | ELEX TOP 2-200 | 2V | 200 Ah (per cell) | Custom rack mount | Central office power |
Note: Always verify specifications on the physical label of your Ericsson ELEX TOP unit, as private labeling for specific telecom contracts may vary.
Installation and Safety Tips
If you are replacing or installing an Ericsson ELEX TOP battery system, follow these protocols:
- Torque terminals correctly: Over-tightening cracks the terminal seal; under-tightening causes arcing. Typically 5–7 Nm (44–62 in-lbs) for M6 bolts.
- Do not mix old and new: Never connect a used ELEX TOP with a new replacement in the same string. The older unit will drag down the entire bank.
- Charge before installation: If the battery has been sitting for 6+ months, perform an equalization charge (14.4V to 14.8V for 12V AGM) before putting it into service.
- Check for bulging: Any ELEX TOP with a swollen case is permanently damaged due to thermal runaway. Dispose of it immediately at a lead-acid recycling center.
- Use a BMS in solar applications: If repurposing an ELEX TOP for off-grid use, install a low-voltage disconnect (LVD) to prevent deep discharge.
Why the Ericsson Elex Top Remains Relevant Today
