Telephone Circuit (Port) Types

There are four types of telephone circuits to which stations can be connected: digital, electronic,
and standard telephone circuits. Also, there are ISDN (S/T) type telephone circuits, terminal
equipment (TE-1) and terminal adaptor circuits.

Digital Telephone Circuit Connections

The Strata DK40i Base KSU and the PDKU2 PCB each provide eight digital telephone circuits.
Each KCDU and RDSU PCB provides four. The RWIU PCB provides circuits to support up to 16
wireless digital telephones.
A maximum of four KCDU PCBs can be installed. If installed, KCDUs should be installed
Note
per configuration tables. The following devices can be connected to digital telephone
circuits (see
swapped using the station relocation feature.

Circuits
Required
Each digital telephone circuit can support a digital telephone.
Only one of the follow
series digital telephone: RPCI-DI, DVSU (SP-OCA) or ADMs.
1
Note The RPCI-DI) and the Add-on Module (ADM) do not
require a dedicated circuit. They share a circuit with the
telephone.
Any digital telephone circuit, except for circuit 8 on a PDKU21,
can support a PDIU-DS.
Note There are two versions of the PDKU2: PDKU21 and
1
PDKU2. The versions are identical, except that circuits
1~8 on the PDKU2 can each support PDIU-DSs/RPCI-DI,
while only circuits 1~7 on a PDKU21 can support PDIU-
DSs/RPCI-DIs.
DDSS consoles can connect only to circuit 8 in the Base KSU
1 and circuit 8 on a PDKU2. The KCDU cannot support a DDSS
console.
DDCBs can only connect to Port 04 in the Base KSU, and Ports
1
12 and/or 20 on either the PDKU2 or KCDU.
