Chapter 1 Overview
1.1 B200P/E BE200P/E Introduction
The OpenVox B200P/BE200P is a PCI 2.2 compliant BRI voice card with 2 S/T interfaces, each of which can be set to TE or NT mode via jumpers. The B200P/BE200P provides a software migration solution from ISDN technology to the new world of Voice over IP by turning legacy ISDN BRI devices into powerful VOIP devices.
The B200P/E BE200P/E works well with GPL-compliant linux kernel drivers to connect your linux machine to ISDN BRI networks. The BE200P/E can be used as a PBX, IVR, and VoIP gateway for clear voice transmission on open source operating systems such as Asterisk®, Issabel, FreeSWITCH™, Yate™, and IPPBX/IVR.

Chapter 2 Hardware Installation
2.1 Power Supply
The B200P/BE200P boards need only 3.3/5V from the PCI slot when working in TE mode. When working in NT mode, users need to provide external power to the board through the 12V 4-PIN D-type connector, otherwise it will not work properly.
The B200E/BE200E boards require only 3.3/12V from the PCI-E slot when operating in TE/NT mode, and no external power supply is required.
The B200P/BE200P are compatible with industry standard 32-bit 3.3V, 32-bit 5.0V, 64-bit 3.3V, and 64-bit 5.0V PCI slots, and are not compatible with any type of PCI-E slots. Users should first confirm the slot type and insert the B200P/BE200P vertically into any of the PCI slots. The following figure depicts the five slot shapes.
The B200E/BE200E are compatible with industry standard PCI-E ×1, ×2, ×4, ×8 and ×16 slots. Users should first confirm the slot type and insert the B200E/BE200E vertically into any of the PCI-E slots. The following diagram depicts the five slot shapes.
Figure 1 PCI and PCI-E Slot
2.3 Setting Card ID
If you need to install multiple voice cards of the same model on one server, then you need to set up the Card ID.
- (a) The ID of the first card must be set to 0, the second card must be set to 1, and so on.
- The first card is the one that is initialized first when the system boots. In most cases, Linux will initialize PCI devices in order, and the PCI device closest to the CPU will be initialized first. That is, if there are multiple B200/BE200s installed on the same server, the card ID of the one closest to the CPU must be set to 0.
2.4 Adjusting the Terminal S/T Interface Mode
The interface of B200P/E BE200P/E can be set to NT or TE mode, please refer to the following figure.
- If the interface needs to work in NT mode, the jumper should be set to connect.
- If working in TE mode, the jumper should be set to disconnect in theory, but the B200P/E BE200P/E may be connected to some non-standard ISDN terminal devices which do not have terminal resistors, and the jumper should be set to connect in this case.
Figure 2 B200P/E BE200P/E jumper setting
2.5 Power supply setting
These jumpers control whether power is supplied to the external ISDN terminal and should be set by the user according to the following prompts.
- (a) If the port is operating in TE mode, the power jumper should be set to disconnect.
- if the port is operating in NT mode, the power jumper should be set to connected, but if the connected device is self-powered, then the jumper should be set to disconnected
- If one of the power jumpers is set to connected, then the user needs to provide external power to the board through the 12V 4-PIN D-type connector, otherwise it will not work properly.
- PCI slots generally provide 3V/5V voltage, but some computers in which PCI slots no longer provide 5V voltage, then the voltage selection jumper should be set to 3.3V input.
- PCI-E slots generally provide 3V/12V voltage, you can select the PCI-E output voltage from the motherboard settings in your computer.
2.6 Hardware Installation Steps
- Power off the computer, remembering to unplug the AC power cord.
- Make sure the jumpers are set correctly.
- check that the Card ID is set correctly first when installing multiple cards.
- Confirm the slot type and insert the B200P/E BE200P/E vertically into the slot.
- If there are ports working in NT mode, insert the 12V 4-PIN D-type connector into the corresponding power connector on the board.
- Set the ISDN telephone line access to the S/T port in TE mode and the ISDN terminal access to the S/T port in NT mode.
- Fixing the board and grounding it.
- Plug in the power cord and power on.
Note : As long as there is a port operating in NT mode, an external power supply is required. Static loops are essential during the above operation and installation or removal of the board should only be done after power is removed. Please check the availability of ISDN line and ISDN terminal before connecting the hardware. After making sure the hardware is installed correctly, you can start the software installation.

Appendix B RJ45 Pin Assignment
ISDN BRI has two kinds of interfaces: U interface and S/T interface. B200P/E BE200P/E provides four-pin S/T interface. We illustrate the pin assignments with the following two tables.
l ISDN U interface
|8-pin RJ45 connector||Pins||Color||Description|
|Green||White/Brown||-48VDC Power (optional)|
|White||Brown||-48VDC Return (optional)|
The ISDN U interface is typically used in North American ISDN networks and uses a standard 8-pin RJ45 connector, but only the center two pins (4 and 5) are used, forming a two-conductor crossover. The optional -48 VDC power pin can be defined by pins 7 and 8 of the RJ-45. This can be used to power NT-1 or TE devices when needed. In most cases, the telephone company does not provide a feed.
l ISDN S/T Interface
|8-pin RJ45 connector||Pin||Color||Description|
|8||Brown||-48VDC Return (optional)|
The ISDN S/T interface also uses a standard 8-pin RJ45 connector, but only four of the pins (3, 4, 5 and 6) are used, forming a four-core straight-through line. Of these, 4 and 5 are used for transmit and 3 and 6 are used for receive. The optional -48 VDC power pins can also be defined by pins 7 and 8 of the RJ-45 and are used to power NT-1 or TE devices when needed.
