Transcript Jumpering and Records

Jumpering a New Line
Providing a new line usually
involves two jumpers, though
some small exchanges may only
require an MDF jumper.
This page deals with jumpering in
a UAX13 but other exchanges will
be similar
Before jumpering a new line, in many exchanges it is necessary first to disconnect
the NU tone jumpers from the "spare“ line number on the "multiple" side of the IDF.
Rearranging the NU tone jumpers and strapping is usually very tedious.
More modern exchanges have final selectors that can return NU tone should the
multiple number be left disconnected. In this case much time is saved.
1
In a UAX13, two jumpers have to be
provided on the frames to connect up a
new line.
1) A two wire MDF jumper between the
cable pair serving the line and the
protector serving the required multiple
number.
2) A three wire jumper is provided on the
IDF to connect the multiple number to
the required linefinder outlet.
Record cards have to be updated within the exchange.
1) The MDF jumper is recorded on the A606 card which is in number order. Note that the
DP cards will also have to be completed so that the full routing is available.
2) The IDF jumper is recorded on the A737 card, which is in number order and the A736
card which is in linefinder bank outlet order.
On the DFR these records are also kept as Excel spreadsheets and so details of changes
to the records need to be advised to the Recorder. Prints of the spreadsheets are made
available for use in the exchange. The spreadsheets are also available on the telecoms
website so that S&T can have up to date access to them.
