Typical Application in a Wired Network
In the diagrams above, a pair of RLH-TG-2A-1 multiplexers create transparent 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. This
configuration guarantees that the T1/E1 channels get higher priority over computer data for maximum
QoS.
