Flexible Attendant Directory Number; Listed Directory Number Calls - Nortel TFC002 Manual

Flexible Attendant Directory Number

Each Remote location can be assigned two attendant DNs to provide access
to the attendants. The Customer Data Block (LD15) allows the modification
of these two DNs. The DN assigned must be a DN taken from the numbering
plan and must not conflict with any other DN. The first is called the attendant
DN (ATDN). Calls to this DN are presented over an RLT to the CAS
attendant if the Remote location is in CAS service. If it is desired that "0" be
the access code for the attendants, then "0" must be specified as the ATDN.
If the Remote location is not in CAS service, the call is presented to the local
attendant or to the night number.
The second DN is called the Local Attendant DN (LADN). Calls to this DN
are presented to the local attendant or to the night number. A call dialed to the
LADN is never terminated on an RLT.
These DNs cannot be made Do Not Disturb (DND) busy, and if they appear
on a Lamp Field Array the associated LED is always dark.

Listed Directory Number calls

Calls to the Listed Directory Number (LDN) of the Main site are treated in
the normal manner: an Incoming Call Indication (ICI) is presented to the
attendant, and normal call-handling procedures are used. If the Remote
location is in the CAS deactivated mode, LDN calls to the Remote location
are also handled in the normal manner by the attendant at the Remote
location.
When the CAS feature is activated at the Remote location, LDN calls to that
location are presented to the CAS attendant with an RLT X ICI indication,
where X represents the RLT route location of the Remote site. If the CAS
attendant console is equipped with a numeric display, the RLT access code
and route member number are displayed.
When the CAS attendant selects the incoming call by operating the loop key
or the ICI key, answer supervision is sent to the Remote site over the RLT.
Two 100-ms bursts of 440 Hz are given, if defined in the Customer Data
Block (LD15). The RLT X ICI indication identifies the call and prompts the
appropriate verbal response.
