A private network replacement would need longer local numbers, possibly
with the leading digits being used to nominally identify the site. Examples
would add nothing to those above.
British public network usage would need entries similar to the ones used
to access the public network above, but removing the leading "9" (the ac-
cess code) and having one less digit. More discrimination on the interna-
tional numbers might be used.
The American public network uses a different technique for discriminating
between local and long distance numbers, so it might include:

This sequence is order critical, except that 911 could be moved higher.

There could be an internal emergency number (3333). This has to be
placed first. It does not conflict with the use of 3 as a first digit. Once
the user deviates from a sequence of 3's, the search will find the other
entry. This entry is only required if it is desired to cancel forwarding and
DND to allow calls to be returned to the caller.
3333,S,,4,,,E, internal emergencies
Refinements could be made to the public network entries as having
critical timing over such a range of lengths might be hard on a caller.
Also, only certain lengths actually exist. Nottingham's local numbers
are typical of large UK cities; smaller cities would have 7 digits, while
London needs 9. Some of these entries are order sensitive.
– 9999,S,,4,,,E, traditional public emergency number
– 99,S,,8,,,, Nottingham local numbers
– 98,S,,8,,,, Nottingham local numbers
– 9112,S,,4,,,E, European standard emergency number
– 9118,S,,6,,,, Directory enquiries, although this would often be barred
by a PABX.
– 91XX,C,4,4,3,,, Special services, in theory, longer numbers can be
used, but there are none at present. Use of "C" will allow these with
changes to this plan.
– 900,S,13,20,3,,, International numbers
– 90,S, 11,12,3,,, National numbers
Secondary dial tone might be wanted after the initial 9. In the initial
case, this can be done by changing the action from "S" to "SD1" . When
the more refined set of numbers are used, they would need to be pre-
ceded by:
9,CD1,1,1,,,, give dial tone after 9
Feature codes starting with * and # might be useful. Studies similar to
that for the public numbers would be needed, but standard values
might be possible for a given server.
