553-3001-306 Standard 10.00 January 2002
— a Direct Inward Dialing (DID) trunk whose DID number is the same
as the LDN
• Calls that originate from internal telephones or TIE trunks when:
— a telephone user dials the LDN
— a telephone user associated with a departmental Attendant Console
dials 0, or
— a TIE-line user dials the LDN.
The DLDN feature associates Attendant Consoles with an LDN. Up to 63
Attendant Consoles can be associated with one LDN.
For call distribution purposes, all Attendant Consoles within a subgroup are
made members of a circular list. When a call is received, it is presented to the
next listed console after the one that was last offered a call, thus ensuring that
LDN calls are distributed in an equitable way. LDN calls, dial-0 calls, and
associated timed recalls are serviced according to a circular list for the
particular LDN.
On receiving an LDN type call, the Meridian 1 searches for an idle Attendant
Console and tests whether or not that console is configured to answer a call
for the dialed Directory Number (DN). If the Attendant Console is not
configured to answer calls for that LDN, the next idle Attendant Console is
tested. If an Attendant Console that can answer the call is found, the call is
presented with the appropriate Loop and Incoming Call Indicator (ICI) lamps
lit. If no idle Attendant Console for the LDN is found, the call is placed in the
incoming call queue for all Attendant Consoles within the customer group.
The Call Waiting indication is provided to all Attendant Consoles within the
customer group. If an Incoming Call Indicator (ICI) key has been provisioned
for the LDN, a lamp indication (with no buzz) is provided to all idle Attendant
Consoles within the customer group and may be answered by pressing the
appropriate key.
