The TP4/III was a completely new technology based on 16-bit microprocessors (68000) the existing TP4/II switches (6502) were 8-bit microprocessors which were slow and out of date in 1989.
Jim Hamrick was very keen to sell us these new switches and as you can see in the email below there were plans to setup training courses for BT People. However at exactly the same time as this email BT announced its intension to buy Tymnet from McDonnell Douglas (see this page) this put us in direct competition with Telenet and scuppered these plans.
To: M.BAKER (TJT106) From: B.ATTWOOD (TJT223) Delivered: Thu 3-Aug-89 15:01 BST Sys 10085 (70) Subject: TELEMAIL 2/8/89 Mail Id: IPM-10085-890803-135280692 Posted: Wed, Aug 2, 1989 7:45 AM GMT Msg: FGIJ-2307-4550 From: PSS.NOG To: RBOND CC: JHAMRICK, DCROKER, PTL.ENG, PSS.NOG, PSS Subj: TP4/III TRAINING COURSE - PROPOSAL Message No 160/9/BSB Roy I am looking at the possibility of arranging for Telenet to provide a training course on the new switch in the UK. This is more practical than sending 12-15 people over to the States and allows us to continue to function operationally. It would be useful to combine the training with hands-on experience, and I see this coming from the TP4/III BT is obtaining on loan from yourselves, with the chance perhaps of visiting Basingstoke if PTL have similar hardware. I see the course taking up to two weeks, probably made up of separate modules such that individuals may need attend only on part of the 2 week period to address their specific areas of interest. Initial thoughts on the content are, 1 Installation - practices - procedures - standards 2 Hardware - archtitecture - config options - functionality eg backup redundancy operation - maintenance practices - spares - support 3 Network Management - TDT - alarms - stats - billing collection - loading, static and dynamic 4 Configuration 5 Performance - packet throughput - call setups - congestion mechanisms 6 Dimensioning I am seeking input from other BT managers to refine this list. I see the course taking place around the end of September, subject to Telenet/ PTL agreement and the installation of the evaluation TP4/III. Please can you a) seek a quotation from Telenet for such a course in the UK, b) advise me whether they can meet the timescale. c) let me know whether PTL have any TP4/III hardware at Basingstoke which may be used to advantage.

My only comment to the letter is that we will provide what assistance is necessary to carry out the recovery. I note that Roy is to give 24 hours notice to Barry Punchard of the removal. I am copying this GOLD to Barry so that he is aware of this and to prepare to receive a call from PTL in this connection. Regards Bryan |
If we had bought these switches I'm sure we would have ended up finding all the bugs for them (by trying out on our customers) as we always did. However I think it was far better technology than Tymnet engines and far better than what came out of subsequent BT procurement exercises which came up with some wacky choices.
