Yes it is a part of a DLSAM. Pictured appear to be Fujitsu line cards - so very likely to be a BT DSLAM.

LDU.JPG
Fairly self-explanatory. This device allows for remote testing of the DSL service on a line. It is a Teradyne Celerity unit to be precise. Again - most likely BT installed and owned:

Pictured above the LDU is an ISDN Terminal Adaptor. Most likely used for out of band management of the DSLAM and/or LDU equipment. i.e. for accessing the DSLAM remotely should it become unresponsive on the wider IP network - the technician can dial into the ISDN line and access a management console on the DSLAM. Sarian 2000 are very flexible so it could be connected to the DSLAM via serial port or ethernet connection.

Expansion cards to enable Caller Display (he says reading the stickers on the PCBs )

local-loop-frame.JPG
Yup that's a distribution frame. Used to interconnect the various pieces of equipment with the lines they are serving - meaning cabling can be hard-wired from there to the PSTN and DSLAM equipment, so enabling a line for service just requires the engineer to cross-connect with a jumper at the frame rather than faffing around running cabling every time.


Interesting pics from what I assume is a tiny exchange

Thanks quite interesting

sheep getting in there is extremely likely. This year however the most damage has been done by verge cutting which comprehensively minced up a few miles of wiring which was laid on the surface; the grass then grew thick over it.
is that standard practice?
we used to have a BT linesman living here. in those days the exchange was immaculate (at least on the outside) and line faults were fixed by him on the same day.

benbird7, thx for your post. Im glad someone looked at it in same spirit with which it was posted.

the whole interest in uplink has come about because of this project

very interesting, thanks.

Not particularly fast but great capacity!

It means that the exchange has been protected against ingress of sea gull excrement.

>>Pictured above the LDU is an ISDN Terminal Adaptor. Most likely used for out of band management of the DSLAM

More likely to be used to communicate with the LDU.

>>Expansion cards to enable Caller Display

This is interesting as it is likely to mean the exchange is a very rare UXD5. Basicly an old Monarch switch.

The link at the beginning of your thread isn't working.
