Adapters, Accessories, and Applications
When the Attendant is set up for after-hours operation, the
time on the Attendant's clock must match the system clock so
the end of the business day is recognized.
The Attendant provides 64 seconds for recording up to five
standard messages, including the caller greeting used during
and after business hours, a hold announcement for a caller
who is being transferred, a connect announcement for the
department or extension receiving a transferred call, and a
message explaining that a call cannot be completed.
Hardware Requirements
012 basic telephone module
MERLIN Attendant unit and cords
Installation
Although the Attendant physically plugs into only one jack on the
012 basic telephone module, it functionally takes up three ports.
Some AC power strips maybe needed since the Attendant is
powered by wall-mounted transformers (10 VAC).
Notes:
Only four ports on the same 012 basic telephone module can
be used simultaneously with Attendant. When four ports are
used for Attendant, only one other port can be connected to a
telephone.
Powering and grounding procedures must follow those
established for T/R telephones that require auxiliary
power.
