Appendix A – General information for the United Kingdom
Note 2: UK regulatory requirements do not permit Call Waiting for an
incoming DDI call terminating on a busy extension. The Call Waiting
feature is denied from DDI trunks for all Meridian 1 systems supplied in
the UK.
Note 3: The approval of the Conference feature is limited. A conference
can include no more than six parties at one time. Although there is
currently no limit set by software, conferences of more than six parties
are not supported and not approved.
Note 4: When incoming Manual Trunk Service is configured so that a
number of trunks auto-terminate on the same Directory Number, one of
the following restrictions must be programmed:
• Hunting or Call Waiting must be enabled
• the number of Multiple Call, Multiple Appearances of a Directory
Number must be equal to or greater than the number of Manual
Trunks terminating on the Directory Number.
Note 5: The New Flexible Code Restriction feature allows a user to
create a list of numbers that are "allowed" and "not allowed" in LD 49.
During an outgoing call, digits are outpulsed as they are dialed. If a
dialed number is identified as "not allowed", the call is cleared and call
barring treatment is applied to the originator. UK approval regulations
prevent the system from applying call barring to a call when more than
four digits have been sent. Entries in New Flexible Code Restriction
tables cannot be greater than 5 digits where they apply to PSTN, ChASS,
or DASS2 trunk routes.
