90-4925-01 Alcatel 2801 MainStreet DTU HDSL Data Termination Unit
For those not in the know the 2801 DTU manufactured by Alcatel / Newbridge is now end of life and becoming increasingly hard to source on the refurbished market.
The 2801 DTU is a client side desk top modem which comes with one universal serial Data port (V.35, V.36, TIA/EIA-449 (RS-449) or X.21) running speeds up to 1 Mb (2w Model 90-4925-01) or 2Mb (2W/4W Model 90-4926-01)
It seems that more and more Telecom manufacturers Alcatel, Siemens & Keymile to name a few are now removing desktop modems from their product portfolios leaving the consumer to resort to 3rd party alternatives. On this note if you have encountered similar issues with other Manufacturers I would like to hear your comments and how to ‘work around’ a solution.
However with the 2801 DTU, Newbridge deployed propriety coding from the line card ( 90-6396-01 - 27LC3-12 LINE CARD) to the 2801 Modem thus no 3rd party DTU’s are available.
At Xbridge we have looked at several migration options for customers including replacing the 27LC3-12 Line Card with the Alcatel GSLC Line Card 90-9553-01.
Over the next couple of postings I will run through the operability testing we have done with several desktop modem manufacturers and list the gains and pitfalls of running with a 3rd party solution.
On the next posting I will detail the testing carried out with the

Good to hear someone is taking the lead with this. With a large installation base there will be a good market for a suitable replacement. Keep me informed please.
