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.
