Cyclades Corporation Director of Technology released a short paper
describing how to replace existing Statistical Multiplexers with the
Cyclades-PR3000/TS Terminal Server.

In most of the multiplex applications, the utilization of the leased
line is extremely inefficient. This happens because most serial
communication occurs in “bursts” and the line ends up staying idle most
of the time.  Another problem is that there is the need to keep two
parallel connections between the remote sites: one for the multiplexer
traffic and another for the Internet/networking data traffic.

This is a tremendous waste of money and time in maintaining the separate
communication lines and equipment.
The ideal long-term solution for the problem is to change the
applications to use TCP/IP client-server architecture and work over the
network. This is usually hard to do because these applications are
typically too old or too critical to the operation to allow easy

A first step in solving the problem can be the consolidation of the
serial traffic with the IP traffic so that you don’t need the extra
leased line. With the Cyclades-PR3000, this can be done in a way that
the application and the serial devices in each side don’t know that the
data is being encapsulated in packets being transmitted over the IP
network. This way, you can change the communication infrastructure
quickly and easily without having to make any change in the application.
If the application is later modified to run over the network, the PR3000
continues to fully support the configuration.

The PR3000 is a full-featured router for the IP network but can also be
equipped with multiple (up to 64 ports per box) RS-232 serial lines to
connect to serial devices or to a host system. The PR3000 can be
configured to transparently connect serial ports over the network (using
TCP socket connections).

With the Cyclades-PR3000 solution you get:
- Cost savings, there is no more need for expensive statistical
multiplexers and leased lines. The investment in the PR3000 is recovered
in a few of months.
- Management and administration benefits. There is only one box and one
network to manage.
- Flexibility and efficiency. While statistical multiplexers usually
connect serial ports between two fixed sites, the PR3000 can connect any
serial port individually to any other site connected to the network.
Before the serial traffic is consolidated into the IP network, idle
communication lines are eliminated.
- The first step towards a client-server implementation. Using the
PR3000, you can first replace the hardware and communication
infrastructure without changing the application. That gives you more
control and security in the migration process.
