Description
The 1 x T1 over Ethernet multiplexer (TDM over IP) product is
used to provide 1T1 communication channel over Ethernet or IP Networks. This
product transmits information at T1 (1544kbit/s).To transport T1 channels over an Ethernet or an IP
network, and to accelerate traditional telecom services to migrate to the IP
packet networking technology, the 1 x T1 over Ethernet multiplexer product
uses TDM over IP technology. This solution transports the legacy T1 data
through the existing Ethernet or IP network.

1 x
T1 over Ethernet multiplexer product is a new
generation of TDM over IP technology with IP circuit emulation that supports
transportation of 1
T1 over an Ethernet or an IP network.
The uplink Ethernet port and user data port are IEEE 802.3
compliant, 10 / 100BaseT auto-sensed ports. The state-of-art design provides
the highest availability with the accurate timing signal and data bit stream
reconstruction. Predefined system parameter profiles that according to
different application requirements; ultimately simplifies the installation
process and saving maintenance cost.
Telecom and Enterprise users can save significant access
and equipment costs and generate new revenue resources by offering different
types of legacy services over Ethernet networks. It is also suitable for
connecting to the Ethernet based wireless equipment to achieve fast
deployment of
T1 services. One particular application is to provide a
combination of Ethernet and
T1 services using low cost Wireless LAN bridges,
or over RPR Ethernet rings. Operators can use the 1 x
T1 over Ethernet
multiplexer to provide a provide a combination of Ethernet and legacy
T1 (TDM)
services over wired or wireless packet networks, or RPR rings.
TDM technology occupies fixed transmission bandwidth which
is suitable for real-time applications such as voice and video. Ethernet
technology 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.
The 1 x
T1 over Ethernet can be used to emulate
transparent T1channels over an Ethernet link with an acceptable QoS (Please
see the note: QOS, below), so that a majority of the existing T1 based
applications can be readily setup over Ethernet LANs and WANs.
(Note:
QOS shall depend on the quality of the Ethernet link and packet losses).
