Survivability
appearance DN ring for incoming calls. The calls can be manually
redirected by any of the users assigned to those telephones.
• However, when IP Expansion Cabinet 1 is in survival mode,
incoming calls to IP Expansion Cabinet 1 (by LDN #1) are terminated
only on IP Expansion Cabinet 1's telephone with the multiple
appearance DN. Only the user assigned to IP Expansion Cabinet 1
is able to redirect these calls. The telephones with the multiple
appearance DN on all other cabinets will not ring in this case.
Advantages:
• Users can receive incoming calls at any time.
• Users can make outgoing calls at any time.
• The CO trunks on the IP expansion cabinets or chassis function in both
normal and survival modes.
Disadvantages:
• Users must inform their contacts of their new LDN.
• The LDN changes if a user relocates to an area serviced by a different
cabinet or chassis.
• Each cabinet or chassis must have a method of redirecting incoming calls
while in survival mode. Use one of the procedures above.
Implementing the Mail intercept feature
When a system's IP expansion cabinets or chassis are in survival mode, the
Mail intercept feature allows incoming calls that cannot be redirected to an IP
expansion cabinet or chassis, to go to the called person's voicemail. The
MBNR prompt in the Customer Data Block must be set to "mail". Enter the
Meridian Mail DN after MLDN is prompted.
