- By definition at the manufacturing stage they can, if they so wish,
- include all current valid digit patterns in PROM. But that's a short
- term situation since telecomms, like most aspects of technology, is a
- developing environment.
-
- How long will those digit patterns stay valid? How can you be sure
- that they will be updated if BELLcore change the rules (as they are
- about to do)? Here in the UK back in 1990, London had an area code
- split. Code 1 split into (71) and (81) -- all calls remained at local
- measured rate. Lots of our COCOTs were programmed to accept (1) as
- local and with about 50 preset exceptions, charge the maximum inland
- landline tariff for all other codes. Instantly all COCOTs started
- charging maximum fee on calls that crossed the split line which meant
- that calls of a few hundred metres were charged as if they were
- routing a few hundred miles (even though the telcos still charged the
- COCOT owner at their "local" rates). Did the COCOT owners rush to
- have the phones reprogrammed?
-
- No, sir, they did not!
-
- There is a need for all COCOTs to have their tariff tables updatable
- remotely (as some already can) and to ensure that the updating process
- is mandatory at the time of a change in the dialing plan. Well, one
- can but dream.

- Happy New Year from Wales to all TELECOM Digest readers .....
