Title: Daily port usage
Post by: polom on December 12, 2006, 08:04:59 PM
I checked my exchange details on http://www.prodigynet.co.uk/menu.php?page=support/adsllinecheck. 
Other checks are saying VPs are Red status.

DSLAM name   Daily port usage      Spare ADSL ports   Available bandwidth (Mbps)
WH-ADSL-1            0                                    0                        120-130
WH-ADSL-101        0                               201-225                   60-70
WH-ADSL-102       -2                                 51-75                     40-50
WH-DSL-001         -1                                 11-15                     90-100
WH-DSL-002           2                                 26-50                    90-100
WH_MSAN_301       0                              676-700                  110-120

What does the negative port usage mean?

perhaps it means less than 1 port takeup per day

i get

I've just done this check and it says: -
Line speed capabilities
      Rate adaptive (250k and 500k) :    Green
      Fixed Rate (1000k and 2000k) :    Green
      MAX speed (up to 8000k) :    Green (7000 kbps)
      250k, 500k, 1000k, 2000k and 7000k are all available on this line.

Why not a maximum of 8000kbps? The other local exchange does go up to 8000kbps, I feel cheated  :o

It means the no of users that have come off that dslam.

It could be for various reasons
1) users may be being moved to an LLU provider who will have their own dslams (for eg sky, talktalk)
2) cancelled adsl or moved house.
3) Moved on to another dslam


I would think 1) would be the most likely reason.

This is my one


BT exchange :    ABERDEEN ASHGROVE
Real time check :    Yes

Line speed capabilities

      Rate adaptive (250k and 500k) :   Green
      Fixed Rate (1000k and 2000k) :    Green
      MAX speed (upto 8000k) :             Green (7000 kbps)

      250k, 500k, 1000k, 2000k and 7000k are all available on this line.


Exchange status

      This exchange is fully enabled for rate adaptive (500k) ADSL, fully enabled for fixed rate (1000k and 2000k) ADSL, and fully enabled for Max ADSL (upto 8000k).

      There are 5 DSLAMS in the ABERDEEN ASHGROVE exchange.



The list is to awkward for me to get into the site without messing about, but its all green at my end so I b the happy one :)  its similar stats to the first post, 01224 is the code for aberdeen and 69 is the most prominent first couple of numbers.

This topic is a bit confused by all the figures and different posts, but I am assuming that we are looking at the capibility and capacity of the DSLAM equipment at our local exchange, including how much bandwidth is available.

I am assuming each ADSL user is on their own port? And daily port usage of 1 refers to your telephone lines connection? and that spare ports are port positions (not a tally) not in use but would be used by any new ADSL user?

Does the available bandwidth mean total bandwidth (i assume it is this) or free bandwidth?

DSLAM name
***-ADSL-101

ADSL enabled
Yes

SDSL enabled
No

Daily port usage
1

Spare ADSL ports
51-75

Spare SDSL ports
0

Short term available ports
151-175

Long term available ports
1526-1550

Available bandwidth (Mbps)
110-120

In service date
Now

Yep each user has their own port.
port usage is the no of new adsl lines connected to that particular dslam (average per day)

My interpretation is:-
spare ports is an approximation of how many more ports are available for immediate use now.
short term ports is an approx of how many more ports are available if they say added another line card(s).
long term ports is an approx of how many more ports are available to reach the dslams maximum capability if they added extra equip for example added another rack. The modern racks normally take 1024 users

available bandwidth is "unlit" bandwidth. 
ATM backhauls are normally 155Mb..  therefore 155-115 means that approx 40Mb is in use.
Some of that 40Mb may be rented out to datastream providers.
