1.  General
1.1 Overview
Thank you for selecting the H0FL-ETHMUX V16 E1/T1 over IP/Ethernet
product designed and made by Beijing Huahuan Electronics Co., Ltd. The product
can be used to provide E1/T1 communication channels over Ethernet or IP
networks.
The H0FL-ETHMUX V16 has many optional parameters, which can be
modified by the user to suite different application requirements. Please read this
manual carefully before installing the product.
It is well known that the E1/T1 signal comes from PCM technology which is
TDM in nature. It transmits information in a constant bit rate of
E1_2048kbit/S(T1_ 1.544Mbit/s), TDM technology occupies fixed transmission
bandwidth, with QoS features suitable for real-time applications such as voice and
video. The QoS features include short and stable transmission delay, low jitter and
wander, etc.
On the other hand, Ethernet is based on statistical multiplexing, transmitting
and exchanging information in packets. It does not take up a fixed transmission
bandwidth, which is good for achieving higher bandwidth utilization. But Ethernet
technology does not provide adequate QoS for real time applications.
Until recently, voice and data were, and still are to a large extent, transported
over two separate networks. But the requirement for both types of information to
be carried over a unified network is growing rapid. Packets over SONET/SDH
techniques to integrate date into the TDM network have been around for many
years. But for voice over packet based data networks, most of the efforts are spent
on creating special equipment that packets voice or video signals, such as VoIP
techniques.
However, to take advantage of the data network, it is neither cost effective,
nor necessary to hastily replace all the TDM based equipment with new packet
based equipment. The H0FL-ETHMUX V16 can be used to emulate transparent E1
channels over an Ethernet with adequate QoS, so that most of the existing E1based
applications can be readily setup over Ethernet LANs and WANs. One particular
suited application is to build E1 links with low cost wireless LAN bridges,
replacing much more costly microwave radios.

1.2 Applications
H0FL-ETHMUX V16 is used to setup 1~16 transparent E1/T1 channels over
LAN or IP networks, as depicted in Fig. 1.2-1.

Huahuan Beijing Huahuan Electronics Co., Ltd.
TDMUX-16 User Manual V1.2 -3-
(a) Application in wireless network
(b) Application in wired network
Fig. 1.2-1 H0FL-ETHMUX V16 typical application
In the figure, a pair of H0FL-ETHMUX V16s create transparent 1~16 E1/T1
channels over the packet network, providing connections between the PBX and
telephone exchange, or other terminal devices. At the same time, computers talk to
each other through the local Ethernet ports on the H0FL-ETHMUX V16’s. This
configuration guarantees that the E1 channels get higher priority over computer data
for maximum QoS.
The most widely used application of H0FL-ETHMUX V16 is to set up point to
point wireless E1/T1 links using low cost wireless LAN bridges. H0FL-ETHMUX
V16 can work with most LAN bridges on the market. It may be necessary to adjust
different parameters such as packet size and packet jitter absorption buffer size for
best operation for different LAN bridges.
Be aware that wireless LAN bridges have a very limited bandwidth. If Ethernet
data is to be transferred at the same time, its traffic must be restricted. Otherwise it
will affect the E1/T1 packets. Since the LAN bridges usually don’t have adequate
QoS mechanism to guarantee the E1/T1 priority, it is strongly recommended that the
data traffic be routed through the H0FL-ETHMUX V16 local data port.
WARNING: When connecting to a wireless LAN bridge, the uplink

Beijing Huahuan Electronics Co., Ltd Huahuan
-4- TDMUX-16UserManual V1.2
Ethernet cable often connects to the outdoor unit, posing danger to lightning
strikes that can seriously damage the equipment. To protect the equipment as
well as people, surge protection devices with good earth connection is strongly
recommended. Poor earth connection may also hinder the operation of the
Ethernet port, causing severe packet losses.
1.3 Timing modes
To emulate a clear E1/T1 channel over a packet network, the H0FL-ETHMUX
V16 not only conveys data stream content correctly from the source to the
destination, but also passes timing. Packet networks do not provide such built-in
timing transparency mechanism as TDM networks do. H0FL-ETHMUX V16 uses
its proprietary algorithm to reconstruct the E1/T1 clock at the destination. The
recovered clock is of very high quality, with low jitter and wander. Typical
frequency offset is within ±5ppm, and jitter is below 0.1UI. It can be adopted in most
applications. This timing mode of rebuilding the E1 clock at the destination is called
Adaptive Timing.
For applications where separate clock distribution network exists, another
timing mode, Loop back Timing, may be used for maximum clock quality.
The two timing modes of H0FL-ETHMUX V16 are depicted in Fig.1.3-1.
Fig.1.4-1 E1/T1Timing modes
Correct timing mode setting is important for smooth operations. In most cases,
setting both units to adaptive timing mode is sufficient. But sometimes, setting one
unit to loop timing mode may work better. For example, setting the
H0FL-ETHMUX V16 unit connected with the clock master (such as local exchange)
to loop back mode, and the other unit connected with the clock slave (such as PBX
or remote module) to adaptive mode, is probably better than setting both to adaptive
modes.
One typical error in telecom applications is to connect two communication
devices that are both clock slaves. Neither will H0FL-ETHMUX V16 support such
operation no mater how the timing modes are set.
Note: that the E1channel emulation takes several minutes to stabilize.
During that period, clock drift may exceed the limit, errors and slips may

occur.
Various timing schemes are listed in Table 1.3-1, for applications depicted in
Fig.1.3-2.

-6- TDMUX-16UserManual V1.2
2.2 Function Description
The core of H0FL-ETHMUX V16 is the TDM/Packet processing unit. It
truncates E1 data stream, putting the data into Ethernet packet with or without IP
headers. The packets are passed to the Ethernet switch unit via MII interface, and
are sent out adaptive the uplink ports. Ethernet data from two local data port are
also sent out through the uplink ports, but with lower priority than those packets
containing E1 data.
In the reverse direction, packets from the uplink ports are sorted at the switch
unit. All but E1 packets are passed to the local data ports. The packets containing
E1 data are sent to the TDM/Packet processing unit for reassembling the original
data stream, and recovering the E1 clock which is the key element of the device.
Very sophisticated algorithm is used to ensure that the reconstructed clock will
meet the stringent requirement of TDM applications. The most important
parameters are jitter, wander, and signal delay.
The control unit interfaces with the user through console port so that various
operational parameters can be modified.

4.  Troubleshooting
This paragraph describes common mistakes and faults that may occur during
installation and maintenance. Please seek support from Beijing Huahuan Electronics
Co., Ltd for other problems.
4.1 E1/T1 Alarms LED on
There are two groups of LEDs, PKT LOS and LOS for E1/T1 alarms LEDs.
When E1/T1 LOS LED is on, loss of E1/T1 signal fault is detected by EthMux.
Possible causes include:
zThe downstream equipment such as telephone exchange or PCM terminal
is powered off.
zThe E1/T1 cable connection looses or broken.
E1/T1 LOS LED blinks when respective input E1/T1 signal is AIS, i.e. the
content of E1 data is all 1’s. Such alarm indicates fault conditions on the part of the
downstream equipment.
E1/T1 LOS site is controlled by Dip Switch RA state. When RA Dip Switch ON,
the red LEDs indicate remote E1 LOS state. When RA Dip Switch OFF, the red LEDs
indicate local E1 LOS state.
The E1 PKT LOS lights are packet loss indicator, On for Ethernet packet loss, Blink
for E1 Packet Loss, Off for Normal.
4.2 Lnk/Act LED off
Lnk/Act LED off means the corresponding Ethernet link is not working. Check
the Ethernet cable connection, and the status of the device on the other end of the
cable.
4.3 Ready LED does not blink
After power on, the Ready LED should start to blink. If not, try switch power

off and on again. If this error persists, call for support.
4.4 Cannot set up E1channel
4.4.1 Same LAN domain
When two H0FL-ETHMUX V16’s are within the same Ethernet broadcast
domain, try following.
Check if the transmission network is on.
Check that the network will pass broadcast packets. For a network that
suppresses broadcast packets, as some of the wireless LAN bridges do, disable ARP
and manually setup local and remote MAC’s.
Check that there is no MAC address conflict on the LAN.
Check that the transmission network has enough bandwidth (more than 2.5Mbps
duplex).
4.4.2 Different LAN domain
When two H0FL-ETHMUX V16’s are in different Ethernet broadcast domains,
IP headers must be used, and packets will be routed by a gateway router, try
following.
Check if the default gateway IP is defined correctly.
Check if the local and remote IP is set correctly.
Check for any conflicts in IP or MAC addresses.
Make sure the transmission network has enough bandwidth.
4.5 Downstream reporting slips
Check if the downstream equipment has correct clock mode. At least one of
them must be clock master. Set the EthMux on master side to loop back timing.
If the downstream equipment on both sides is not synchronized, slips are not
avoidable.
At the transition time after power on or reapplying the E1signal, slips and errors
are acceptable. Such transition may take several minutes.
5.  Web Manager
Both Web Server and SNMP management are supported through anyone of two
user data ports of H0FL-EthMuxV16.
