Chapter 1 Overveiw
The Synway TEJ series (hereinafter referred to as ‘TEJ’) are high-performance, cost-effective
digital telephony interface boards and support E1, T1 and J1 environments. The environments are
selectable on a per-board basis via software configuration. The TEJ boards improve I/O speed by
using DMA technique for data reading and writing on the basis of PCI bus, resulting in reduced
CPU usage and increased board density per server. They provide the power to interconnect
traditional telephony systems with emerging Voice-over IP (VoIP) technologies.
Compared with other products in Synway AST series, the TEJ board has high integration. It is
integrated with the capability of 64ms echo cancellation, eliminating the need of getting supports
from extra modules or devices, bringing an obviously better effect of echo cancellation than other
subseries in AST.
The excellent combination of the TEJ driver and the Asterisk platform brings the following features
to the TEJ series boards.
Supported Data Modes: Cisco HDLC, HDLC, PPP, Multi-link PPP, Frame Relay.
Supported Voice Modes:
PRI CPE and PRI NET
—NI1
—NI2
—EuroISDN
—4ESS(AT&T)
—5ESS(Lucent)
—DMS100
E&M
—Wink
—Feature Group B
—Featrue Group D
FXO and FXS
—Ground Start
—Loop Start
—Loop Start with Disconnect Detect
The TEJ series connect Asterisk Server with PSTN, Channel Bank or PBX via T1 or E1 interface.
The boards and the corresponding drivers can be used to establish a professional telephony
network environment. Figure 1-1 and Figure 1-2 below are typical application models with TEJ.

1.1 Features
zPCI 2.2 Bus Support
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; universal PCI design supports 3.3V/5V PCI
slot.
zDMA Read and Write
The use of PCI-based DMA technique for data reading and writing helps minimize the cost
of the host CPU.
zCompatible with Asterisk
Entirely compatible with Asterisk at the hardware/driver level, with all source codes open.
zRJ48C Jack
TEJ-1A/PCI, TEJ-2A/PCI and TEJ-4A/PCI boards respectively have 1, 2 and 4 RJ48C
jacks which can either connect directly with digital trunks or convert to BNC connectors via
a proper adapter, making connection easy and malfunctions rare.

The self-adaptive echo cancellation feature gives the board the capability of 64ms echo
cancellation so as to effectively eliminate echoes under various conditions, canceling out
the effect of voice playback on DTMF and busy tones detection, avoiding self-excited
oscillation and howling, and minimizing the possibility of registering wrong DTMF and busy
tones in a conference call, designed especially for VoIP application environments.
zVoice CODEC Support
Supports A-law, μ-law codecs.

Interface Identification
It’s quite important to recognize different kinds of interfaces, as such information is necessary for
configuration of Asterisk platform. In real practice, not all interfaces on the board are used at a
same time. When to use which interface depends on the installed modules and their particular
positions on the board.

The TEJ-1A/PCI, TEJ-2A/PCI and TEJ-4A/PCI boards include PCI 2.2 bus and support 3.3V/5V
PCI slots. That is, they support the slots numbered 1, 2 and 3 in Figure 2-5, but don’t support the
slot numbered 0 (AGP slot). The available PNP (plug and play) feature eliminates the need for
jumper leads.
