146 Call Forward No Answer, Second Level
Multiple Appearance Directory Numbers
Call redirection parameters like Hunt and Call Forward No Answer are
derived from the TN data block (LD 20 TNB) of the prime appearance of the
called Multiple Appearance Directory Number (MADN). If there is more than
one prime appearance, the parameters are selected from the last TN in the
DN block for the DN (LD 22 DNB).
If more than one prime appearance of a MADN exists, the following
information must be considered prior to configuring call redirection
parameters for MADNs.
The DN Block organizes MADN information in numerical TN order. The TN
with the highest numerical value (000-0-06-03) is placed at the beginning of
the list. The list then continues in descending order with the lowest numerical
TN (000-0-03-01) at the end of the list. Service change activity affects the
organization of the DN list as described in the following paragraphs:

It is recommended that DN Message Center stations be denied CFNA,
Call Forward Busy (CFB), Call Forwarding (CFW), and Call Hunting
(HUNT).
If a telephone undergoes Service Change, its TN is moved to the
beginning of the DN list, irrespective of the numerical value. This
telephone remains at the beginning of the list until another Service
Change or a SYSLOAD.
If a DN is assigned as a Prime DN on a telephone and as a secondary
DN on one or more telephones, the DN list is still organized as described
in the preceding paragraphs. If only one prime appearance of a DN
exists, however, call redirection parameters are derived from the TN of
the prime appearance telephone, even though it may not be at the end
of the list. A prime appearance is always the first TN used when the
system looks for call redirection instructions.
If a DN appears on analog (500/2500 type) telephones, and Meridian
1 proprietary telephones, the analog (500/2500 type) telephones are
listed in numerical TN order at the top of the list. Meridian 1 proprietary
telephones are listed in numerical TN order at the bottom of the list. A
service change to an analog (500/2500 type) telephone moves its TN to
the beginning of the list. A Service Change to a Meridian 1 proprietary
telephone moves its TN to the end of the list.
A SYSLOAD restructures the list with analog (500/2500 type) telephones
at the top and Meridian 1 proprietary telephones at the bottom. Call
redirection parameters continue to be derived as described in the
preceding paragraphs.
