1.1 Features
Overview
The BRI16 full-length board (hereinafter referred to as BRI16) is designed with a smart
appearance and a flexible structure. The voice quality it provides is rather splendid. The echo
canceller which we developed out independently to cancel echoes in hardware supports 128ms
for time delay estimation. With the extendable daughterboards and the selectable modules, you
can customize systems to what you want. The half-height and full-length design it has minimizes
the space to install in a chassis so that most common main frames you find in daily life are big
enough to hold it. In a word, this product is really cost effective.
Note: The BRI16 full-length motherboard can extend only with a daughterboard to set up a
system involving up to 16 ports. To be exact, each motherboard supports up to 8 channels
and the extension with a daughterboard which is achieved by the backboard BP200,
enables the support of 16 channels. See Figure 2-1.
zEcho Cancellation
1) Compliant with G.168-2002.
2) The basic motherboard supports 256 point (32ms) for time delay estimation on each
channel while the enhanced motherboard supports 1024 point (128ms).
3) Uses the DSPs on the motherboard to process echoes, not wasting any host resources.
zDMA
Uses the DMAtechnique for data reading and writing, greatly minimizing the cost of host CPU.
zStructure
1) Assembles piecemeal just like piling up building blocks. A motherboard offers 8 channels
and you may use the backboard to extend with a daughterboard to support up to 16
channels. Although the daughterboard takes some space, it works without the need of
PCI/PCIe slots (at present we can only provide the motherboard that is applicable
to PCI and PCI-X slots, and the daughterboard is unavailable now).
2) Several kinds of modules are optional for you to install with the mother/daughter boards
to achieve different purposes. At present we provide NT200 and TE200.
3) The half-height and full-length design (Height: 64mm, Length: 270mm) minimizes the
space for installation, allowing a great many choices of mainboards and main frames.
4) You may use the spring steel buckle to fix the backboard on the mother/daughter board
so as to prevent them from loosening or disengaging during transportation or removal.

zCompatibility in Software and Hardware
1) Compatible with all commercial and home mainboards.
2) PCI board includes PCI 2.2 bus with burst data transmission rate up to 132 MB/s; PNP
(plug and play) feature eliminates the need for jumper leads; general PCI design
supports 3.3V/5V PCI slot and PCI-X slot.
3) PCIe board includes PCI Express 1.0a bus with the single-way transmission rate up to
2.5Gb; supports PCI Express X1, X2, X4, X8, X16 slots (the board with PCIe bus is
unavailable now).
4) Supports Unix, Linux and Solaris.
5) This board driver is compatible with Zaptel. So it supports a lot of open source PBX
systems, like Asterisk, Trixbox, Yate, CallWeaver, FreeSwitch, etc.
zInterface
Four on-board RJ45 jacks: to connect with BRI lines (don’t forget to install BRI modules
correspondingly), use the two-way hub for RJ45 to convert each RJ45 to two S/T jacks which
can directly connect to BRI lines, making connection easy and malfunctions rare.
zPower
The power is supplied by the host computer. In case only the motherboard is used, connect it
with the HD power plug; in case the backboard and the daughterboard are also used, connect
the backboard with the HD power plug.

2.2 Interface and Channel Number Identification
The BRI16 full-length board uses the RJ45 interface. The motherboard and the daughterboard
respectively provide four 8-pin RJ45 jacks each of which corresponds to one module and two BRI
channels. That is to say each RJ45 jack has 8 pins and corresponds to two S/T interfaces. See
below for the pin layout of the RJ45 jack with two different modules.
When corresponding to the NT200 module, see Table 2-2.

and Pin8 correspond to the other. In this way, each RJ45 accommodates two channels.
A BRI16 full-length board provide up to 16 channels each of which has a fixed number.

daughterboard are the same as that for the motherboard. The unique difference just lies on
the channel number. When the motherboard is used with the daughterboard, channels on the
motherboard are the first 8 channels (CH1~CH8) and those on the daughterboard are the
latter 8 channels (CH9~CH16). It doesn’t matter that on which position of the backboard the
motherboard or the daughterboard is fixed, or whether a slot is inserted with a board or not.

Step 7: Set up an application environment.
Connect the line from the NT port in central office with the TE port and the line from the TE port
in central office or an ISDN phone with the NT port to set up an application environment. If the
TE port in central office or the ISDN phone requires the NT port to provide feed, you should
turn on the PSW slide switch of the corresponding channel as well as the slide switch
corresponding to Port1 or Port2 on the module NT200.
