Digital Extensions
The following instructions explain how to connect digital extensions. These
instructions apply for key phones and Digital Single-Line Telephones
(DSLTs). Special instructions are provided for installing the DSS/72 and
EM24 terminals, which connect to digital phones.
1. Install the DEC cards in extension slots.
2. Use a standard 50-pin cable to connect the extensions from the MDF to
the appropriate extension connector, as shown in Figure 4-13 on page 4-
31. (Refer to Tables 4-20 through 4-22 for extension pinouts.)
3. If you are installing a DBS 40, attach the EMI filter to the amphenol
cable, as shown in Figure 4-15.
DSS/72
Guidelines
• 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.
• 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 .
• 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.
• 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.
• The DSS/72 comes with a mounting bracket, screws, and a two-conductor
cable for attaching the DSS to the key phone.
