[Tagging] Outdoor DSLAM

[Andreas Labres]

I'm looking for a good tagging for an outdoor DSLAM:

http://de.wikipedia.org/wiki/Digital_Subscriber_Line_Access_Multiplexer
http://en.wikipedia.org/wiki/Digital_subscriber_line_access_multiplexer

(in Austria they are called ARU = "Access Remote Unit" and bear a label
"ARU###", so they are rather easy to identify; and they spring up like mushrooms
these days)

http://wiki.openstreetmap.org/wiki/Tag:man_made%3Dstreet_cabinet#Street_cabinet_categories
suggests:

man_made=street_cabinet
street_cabinet=telecom

but this "telecom" is too little as it doesn't distinguish the DSLAM
functionality (with an active DSLAM component) from a regular old
"Kabelverteiler" (cable distribution box, which is just passive).

Taginfo finds:

communication=outdoor_dslam 291
man_made=Outdoor DSLAM 18
and some notes and comments

So it seems suitable to tag:

man_made=street_cabinet
street_cabinet=telecom
communication=outdoor_dslam

Comments?

Think the type of communication transmitted is tagged with name space so far

communication:mobile_phone=*


communication:dslam=outdoor ?
communication:outdoor_dslam=* ?

Hello,

That's a nice question

My suggestion :

man_made=street_cabinet (for the enclosing cabinet)
street_cabinet=telecom (indicates the type of stuff hosted
telecom=dslam (It's a DSLAM)
location=outdoor (It is actually outdoor)
medium=copper (Land lines linked to it are made of copper).

I don't like to put indoor/outdoor in a namespace or in a key name when
location=* is here to do the job.



All the best

location=outdoor (It is actually outdoor)

This doesn't make sense to me. The location is given by the coordinates. If
those coordinates are within an area building=yes can be determined if necessary.

But "Outdoor DSLAM" is a fixed term (AFAICT) for this FTTC cabinets. Maybe
street_cabinet=FTTC might be a solution. But I think I'd prefer
street_cabinet=outdoor_dslam. This precisely enouth tells what it's about. And
it can be queried easily. Using 3 tags to specify one feature is error prone,
I'd say.

BTW, a telecom street cabinet can only be either a "Kabelverteiler" (which is a
passive wire distribution point) or an outdoor DSLAM, so it would make sense to
classify both with street_cabinet=...

medium=copper (Land lines linked to it are made of copper).

It's FTTC (fiber to the cabinet), so it's fiber on the provider side. It's of
course copper for the "last mile". But this is all clear with the specification
"outdoor DSLAM".


Regarding fly's suggestion: a mast or communication tower can be equipped by
multiple antennas/masts with antennas. So the feature=yes/no solution is
necessary. But street cabinets tend to have only one "dedication".

location=* is a bit more complex than "to be inside an OSM building area or
not".

Furthermore and IMHO, it doesn't sound consistent to ask for a geospatial
lookup for the location and ask for street_cabinet=outdoor_dslam just
because it is "easy" to query.

If the "outdoor" data must be added, it should go in location=* instead of
creating a very particular value.

DSLAM is a fixed term. It can be indoor inside a central office or outdoor
in a cabinet in the street.
This is exactly the same hardware inside
http://www.infos-reseaux.com/photos/album/35-deploiement-fttc-bt-openreach-fttc-openreach-deployment

You can find them indoor too and telecom=dslam + location=indoor would be
really appreciated.

Thus, I don't see any clear reason to hardly link outdoor and dslam inside
a single tag value.
telecom=dslam + location=outdoor gives us more benefit than downgrades.

I've heard of passive connection points mapping and
telecom=connection_point sounds to be the selected value for this.

I agree
I was talking of the service-side of the DSLAM, but telecom:medium (instead
of weak medium=*) isn't really clear

necessary. But street cabinets tend to have only one "dedication".

If such occurs in reality, each mast and each cabinet should be tagged
separately and the whole site ref should be put in a relation containing
all that stuff.

The problem here is : what if several DSLAM are hosted in the same cabinet ?
Or worse : What if a DSLAM is hosted in a connection point cabinet ?

It's nearly the same question in power where transformers can be hanged at
pole's top.

It has been solved with power=pole + transformer=yes
So for DSLAM in a connection point : telecom=connection_point + dslam=*


Just my 2 cts for the last part of this mail


Cheers !

It can be both but its you cant tell from the outside. In the "early
days" of the FTTC/DSLAM Rollout the German Telekom used to construct the
outdoor_dslam cabinets on top of the old cable distribution cabinets
(modulo the real casing). If my information is correct they stopped
doing so because of cost.

This page has an Image of an outdoor_dslam casing with
the cable distribution part left intact.

http://internet-lippinghausen.de/

You can see the construction process from de-casing the old distribution
cabinet and fitting the new outdoor_dslam casing around.
