[TCUG] Re: Use of fibre-optic, IP addressable UTC

We have a network of 4 OTUs linked by fibre optic cables.  Each end of
the network has a single EPS9 BT line from two different local authority
offices, and the IP addressed signals arrive there from our corporate
network.

This has now been operating for about a year, with the only
interruptions due to foreseeable IT work on the corporate network.

Our Siemens Alpha drives 20 other sites in Preston on IP addresses via
direct EPS9 lines, and lots of other legacy sites all over Lancashire
using Ferranti Mk1 and Mk2 OTUs, via a Peek FEP (front end processor) on
multipoint bearers.

Subject: [TCUG] Use of fibre-optic, IP addressable UTC

A colleague has recently finished a project implementing UTC control,
utilising fibre-optic connectivity to traffic signal controllers, with
IP addressed O.T.U.'s running in real-time. The system has been running
successfully since commissioning.

He is curious to know if anyone else has completed (or has plans for) a
similar project, and any issues they may have encountered.
