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.
