Nortel Networks 1000M - Manual (Page 315)

Configuring for Survivability 315
The following example illustrates the process for manually
distributing calls to the user:
• In normal mode, incoming calls to IP Expansion Cabinet 1 are
processed by the main cabinet’s answering service (which could
be an attendant, or Meridian Mail). When the main cabinet’s
answering service is in night mode, all the telephones with the
multiple 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.
The MBNR and MLDN prompts are configured in LD 15.
