Chapter 1 Overview
The Synway TEJ400E, TEJ800E, TEJ401E and TEJ801E are digital trunk interface boards which
support E1, T1 and J1 environments. They are in 2U size, 120mm in length, compact in structure
and high in integration. They all include PCIe bus, designed especially for various application
systems that require high performance.
They all perform echo cancellation by on-board DSPs. The enhanced capability of TEJ401E,
TEJ801E in echo cancellation reaches 128ms for time delay estimation, which ensures
high-quality voice talk without extra modules or devices to support echo cancellation. They are
absolutely cost-effective. The design of on-board EMC and lightning-proof circuits further
guarantees the security in use.
These boards are completely compatible with Asterisk in hardware 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:
PRI CPE and PRI NET
—NI1
—NI2
—EuroISDN
—4ESS(AT&T)
—5ESS(Lucent)
—DMS100
E&M
—Wink
—Feature Group B
—Feature Group D
FXO and FXS
—Ground Start
—Loop Start
—Loop Start with Disconnect Detect
These boards connect the Asterisk server with PSTN, Channel Bank or PBX via T1, E1 or J1
interface to build a specialized telephony network environment. Figure 1-1 and Figure 1-2 below
are typical application models with these boards.

Figure 1-2 Application Model II: VoIP Telephony System
zPCIe Bus Support
Includes PCIe bus; supports PCI Express X1, X4, X8, X16 slots and the PNP (plug and play)
feature.
zDMA Read and Write
The use of DMA technique for data reading and writing helps minimize the cost of the host
CPU.
zCompatible with Asterisk
Entirely compatible with Asterisk in hardware, with all source codes open.
zRJ48C Jack
The TEJ400E, TEJ800E, TEJ401E, TEJ801E boards all have four RJ48C jacks. TEJ400E
and TEJ401E have common RJ48C jacks which can either connect directly with digital
trunks or convert to BNC connectors via a proper adapter, while TEJ800E and TEJ801E
have special RJ48C jacks (RJ48C/M) each of which can convert to two common RJ48C
jacks via a two-way hub, making connection easy and malfunctions rare.

1.2
The echo cancellers that Synway developed for these boards use on-board DSPs to work.
TEJ401E and TEJ801E support up to 128ms for time delay estimation per channel, while
TEJ400E and TEJ800E support 32ms, 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
Supports A-law, μ-law codecs.
zClock Sync Support
Supports input and output of CT clock, allowing clock synchronization with multiple boards.

Notes:
1) PCM0~PCM7 in
Figure 2-1 above are 8 transmit/receive interfaces to trunks.
2) LED1~ LED8 are indicators for PCM0~PCM7. They have three states as listed below.
○
1 On: PCM synchronous; ○ 2 Flashing: PCM not synchronous; ○ 3 Off: Port unused
3) INm and OUTm respectively indicate the grounding jumpers at the receive and transmit ends
of PCM(m-1), m＝1～8. With regard to the configuration of grounding jumpers, refer to Step 1
in Section 2.5 Hardware Installation.
4) JP12 is an interface to the clock sync line.
5) Except for the number of transmit/receive interfaces to trunks, the TEJ400E/401E board is
almost the same as TEJ800E/801E in appearance. The picture is only for reference, please
make the object as the standard.
2.2 Interface Identification
TEJ400E and TEJ401E adopt common RJ48C jacks. See Table 2-1 below for the pin layout of a
standard RJ48C.
