Electronic Telephone Circuit Connections

There are no electronic telephone circuits in the Base KSU, and none can be added to it. However,
either the PEKU PCB, which has eight electronic telephone circuits, or the PESU, which has four
electronic telephone circuits, can be installed in the Expansion KSU.
The following devices can be connected to electronic telephone circuits (see
Table 2-8 Electronic Telephone Circuits
Electronic Device
Electronic telephones

CAUTION!

Standard Telephone Circuit Options

In addition to supporting standard telephones, each of the standard telephone circuits can support
any one of a number of single-wire-pair devices, including voice mail/Auto Attendant devices and
modems (see

ISDN Station Devices

Each device requires a DK40i BRI circuit configured for station side, as opposed to line side. Two
BRI circuits are provided by each of the ISDN PCBs. ISDN station devices include ISDN
telephones, modems, terminal adaptors, video cards, etc. A maximum of 10 BRI circuits can be
provided for ISDN stations. BRI station circuits do not use up line capacity in DK40i Release 4.3.

You must always calculate the Power Factor (PF)—see Worksheet 2. Exceeding
the PF will cause the power supply to fail. If PF is exceeded, replace EKTs with
DKTs.

KSTU2
Comments
Each electronic telephone circuit can support an electronic
telephone.
The system supports only one HDSS console. The console must
be connected to both circuits 7 and 8 on the PEKU. The PESU
will not support an HDSS console.
The system supports an alternate BGM source which can be
heard over digital and electronic telephone and external page
speakers. This source can be connected to either circuit 3 on a
PEKU, circuit 8 on a PESU, or circuit 4 on a KSTU2 or PSTU
PCB.
Up to three amplifiers for two CO line conferencing can be
connected to ports 9 and 10; 17 and 18; and 24 and 25 on a
PEKU or PESU.
