This setting tells the system what type of line protocol the route uses to
process the dial string.
The heading changes between DN type and Service type, depending on
the PRI line protocol. Refer to
“Programming the PRI routing table” on
page 337 .
MCDN private networks: Local, National and Special are special
designators used to route calls from Meridian 1 systems, through Business
Communications Manager systems, out to the public network. The codes
for these settings are defined in the Access codes table. Refer to
“Using
the MCDN access codes (tandem calls)” on page 327 .
When the Business Communications Manager receives outgoing calls
from the Meridian 1, it recognizes the call type and appends the
appropriate access code to the Meridian dial string.
This code then matches to a route that uses the same DN type, passing
the call along, either to another node (the route would have the same DN
type) or to the public network (the route would have a Public DN type),
depending on the routing information.
Outgoing call display: If you have the trunks set up to send called
number information ( “Defining trunk module types and settings” on page
142 and “Identifying BRI T-loops (ETSI, QSIG)” on page 282 ), and the DN
type is set to anything, except Private, the system sends the Public OLI
number you specified under line programming. If the DN type is set to
Private, the system sends the Private OLI number. Refer to
“Configuring
line access” on page 405 .
