The SBC
Base Models
The beroNet Session Border Controller has 3 different Base Models:
| Model | Session Maximum | Module Expansion Slots | Front Picture |
|---|---|---|---|
| BNSBC-M | 8 | 2 |
|
| BNSBC-L | 32 | 3 |
|
| BNSBC-XL | 64 | 3 |
|
The BNSBC-M has 2 Expansion Module expansion module slots and the BNSBC-L and BNSBC-XL have 3 Expansion Module Slotsexpansion module slots. For each Module module, a Block block of 4xRJ45 connectors are installed. What kind of modules can be installed is described in the next chapter.
The back side of the SBCs are the same for all models (except that the BNSBC-L and BNSBC-XL are a bit wider compared to the BNSBC-M):
The SBC features 2xLAN Ports
- 2x LAN ports (LAN and WAN)
- PCM connector,
...
- which can be used to connect
...
- 2 SBCs to share PSTN
...
- data and timing and to perform a hardware factory reset with a jumper on the 8th row.
See more under How to do a Hardware Factory Reset (Gateway V2 / SBC - VoIP Gateway) Page. - MicroSD slot which is currently not used and a 12V DC power connector (24W maximum usage).
Opening the SBC
To If you need to open the SBC in order to add add /remove Expansion Modules you should open expansion modules, you need to detach the front panel with 4 screws and remove the top panel as shown in the picture:
You can see the 3 Module module slots and corresponding 3 Module Connectorsmodule connectors.
Modules
All Modules that fit in the beroNet Gateway and Card range can also be used in the beroNet SBC:
- Hybrid: 2BRI + 2FXS (BNMO-2HYB)
- Analog: 4FXS / 8FXS / 4FXO
- Mobile: 2GSM / 2LTE
ISDN (high precision +- 2.5PPM):
4xBRI4BRI /
2xPRI2PRI (E1/T1) /
1xPRI1PRI (E1/T1)
- the old 2xE1 and 1xE1 Modules work also, but have no high precision clock.- Hybrid: 2BRI + 2FXS
- Analog: 4xFXS / 8xFXS / 4xFXO
- Mobile: 2xGSM / 2xLTE
/ 1E1 / 2E1
Info Starting in 2021, the 1E1 and 2E1 modules are also equipped with a high precision clock.
Module Connectors
Depending on the Module different Connectors are used within the Gateway:

Pin Layouts
BNMO-4BRI (4x BRI/ISDN)
The BNMO-4BRI module has 4 ISDN/BRI ports. The module can be configured individually for each port to NT (Network Termination) or TE (Terminal Equipment) mode.
In either mode the module supports Point-To-Multi-Point (PMP) or Point-To-Point (PTP). The TE/NT mode as well as the line-termination of 100 OHMs are selectable via software (Jumper Freejumper free).
The ISDN Ports use the following RJ45 Pins:
| Port X | |
|---|---|
| PIN | Usage |
| 3 | TX+ |
| 4 | RX+ |
| 5 | RX- |
| 6 | TX- |
BNMO-xPRI and BNMO-xE1 (1,2 ports ISDN PRI)
The BNMO-xPRI modules are available as 1 port or as 2 port variants. The modules can be configured individually for each port to NT (Network Termination) or TE (Terminal Equipment) mode. If you want to use NT-mode you may need a cross cable which is optionally available (the BNE1Cross).
Line termination (120 ohm) is selectable for each port by DIP switches on the module(2 per port). Only the
The BNMO-xPRI have are equipped with a " high precision clock " with +- 2.5ppm.
Starting in 2021, the 1E1 and 2E1 modules are also equipped with a high precision clock.

...
The BNMO-4FXS module is a 4 port FXS module for the beroFix beroNet baseboards and boxes. The BF4FXS module is used by small and medium enterprises which need internal analog FXS ports to connect analog phones, faxes and modems.

BNMO-4FXO (4 ports analog FXO)
The BNMO-4FXO module is a 4 port FXO module for the beroNet mainboards and boxes. The module provides 4 FXO (Foreign Exchange Office) ports for the beroNet SBC.
It can be used to connect a SoftPBX to the PSTN as well as a traditional PSTN based PBX. It is fully compatible and can be combined with all beroNet modules, cards and boxes.
The pinout looks like:| Port X | |

BNMO-HYB (2 ports ISDN BRI + 2 ports analog FXS)
The BNMO-HYB Hybrid Module is a 2 Port BRI and 2 Port FXS Module for the beroNet Baseboards and Boxes. Each BRI port can be configured as NT (Network Termination) or TE (Terminal Equipment). In both modes, each BRI port can operate in Point-to-Multi-Point (PMP) or in Point-to Point (PTP) mode. The switching of the TE / NT mode and the deactivation of the termination resistors can easily be set in the software (Jumper Free) which makes the troublesome repositioning of jumpers unnecessary. Additionally the module provides 2 ports FXS (Foreign Exchange Station) for the beroNet Gateway. FXS interfaces are used to connect devices like analog phones or faxmachines faxes to your beroNet SBC.
The Pinout for the different port looks like:
| Port BRI-1, BRI-2 (ISDN) | Port FXS-1, FXS-2 (FXS) | ||
|---|---|---|---|
| PIN | Usage | PIN | Usage |
| 3 | TX+ | 4 | RING |

| 5 | RX- | - | - |
| 6 | TX- | - | - |
