DSS/72
Guidelines
l
The DSS/72 (VB-43320) is a 72-key console that can be attached to the
attendant phone. It provides direct station selection and busy lamp fields
for internal lines. The
DSS/72
can also be used for text assignment.
l
When the attendant feature package (VB-43330) is installed (CPC-B
Version 2.0 to 4.0 only), the
DSS/72 can be used as an Attendant Console.
The Attendant Console provides station monitoring and call transfer by
name for large systems, even if a large display phone is not used. For a
detailed description of the differences between the standard DSS/72 and a
DSS/72 configured
as,an
Attendant Console,
see Feature Operation,
Section
700. For instructions on using the Attendant Console, see
the
Attendant Console User Guide, Section 760.
l
Up to two DSS/72s or one Attendant Console can be assigned to attendant
phones 1 and 2. Attendant phones 3 and 4 can each have one Attendant
Console assigned, but neither can have a
DSS/72.
l
If more than one
DSS/72
is assigned to an attendant phone, only one of the
DSS/72s can be cabled from the same wall jack as the attendant phone.
Additional
DSS/72s must be cabled from separate wall jacks.
l
The DSS/72 comes with a mounting bracket, screws, and a two-conductor
cable for attaching the DSS to the key phone.
