Chapter 1 Overview
The Synway TEJ101E and TEJ201E are digital trunk interface boards which support E1, T1 and
J1 environments. They are in 2U size, half-length, compact in structure and high in integration.
They use high-performance standard PCIe bus, designed especially for various application
systems that require high performance.
The TEJ101E and TEJ201E boards perform echo cancellation by on-board DSPs. The echo
canceller developed by Synway supports up to 128ms for time delay estimation, which ensures
high-quality voice talking without the help of extra modules or devices for echo cancellation. They
are cost-effective. The design of on-board EMC and lightning-proof circuits further guarantee the
security in use.
These boards are completely compatible with Asterisk at the hardware/driver level and support
smooth connection to Asterisk platform. Therefore they have a lot of advanced call features.
Supported Data Modes: Cisco HDLC, HDLC, PPP, Multi-link PPP, Frame Relay.
Supported Voice Modes:

128ms for time delay estimation per channel, really cost-effective. It not only cancels out
the effect of voice playback on DTMF and busy tones detection, but also avoids self-excited
oscillation and howling, and minimizes the possibility of registering wrong DTMF and busy
tones in a conference call, designed especially for VoIP application environments.
zVoice CODEC Support

2.5 Hardware Installation
Note: Always turn off the power before installation!
Step 1: Configure the grounding jumper.
To use 100ΩT1, 110ΩJ1 or 120ΩE1 balanced twisted-pair cable, disconnect all grounding
jumpers.
In consideration of various line conditions, this series boards are equipped with two groups of
grounding jumpers on each channel which respectively control the groundings of the transmitting
and receiving ends. In case the 75ΩE1 unbalanced coaxial cable is used, the grounding jumpers
at the receiving end should be disconnected while those at the transmitting end should be
short-circuited, provided that the PC is properly grounded. This configuration is the factory default
setting and applicable to most situations so that there is usually no need to change it. If it is difficult
to ground the local PC, you may short-circuit the on-board grounding jumper at the receiving end
and use the transmitting end at the opposite terminal for grounding. If the receiving end at the
opposite terminal is grounded (improper operation), the on-board grounding jumper at the
transmitting end must be disconnected. Refer to

Table 2-2 for details.
Generally speaking, even in the case of proper grounding at both terminals, only the external layer
of the E1 coaxial cable at the transmitting end is allowed to be grounded. The grounding of both
transmitting and receiving ends may result in a current loop with ground wires, bringing instability
to signals. Therefore, such grounding must be strictly avoided.

Step 2: Properly fit the board onto the PC chassis.
It is suggested to fix the L-brackets on the board with screws before going to the next step.
Step 3: Connect to digital trunks.
Synway TEJ101E/TEJ201E Hardware Manual (Version 1.0) Page 8

Synway Information Engineering Co., Ltd
Each board provides 1~2 RJ48C jacks, each of which can either connect directly with digital trunks
or convert to 2 BNC connectors via an RJ48C-to-BNC adapter. See Figure 2-6 below.
Figure 2-6 RJ48C-to-BNC Adapter
Step 4: Set up an application environment.
Connect digital trunks with the on-board RJ48C jack to establish an application environment.
Step 5: Connect the clock sync line.
Note: Skip this step if there is no need of clock synchronization with multiple boards.
The on-board clock sync line is used to connect with other boards, such as digital trunk boards,
analog boards from Synway or even boards from other companies, to offer a same clock to all
boards connected together. This can reduce the error in faxing and guarantee the accuracy in data
transmission between boards.
See Figure 2-7 below for the clock sync line provided by Synway.

Step 6: Boot your computer and install the driver.
