NOTES:
1. The appropriate capacities apply to digital and 6500-series electronic telephones only. If other Toshiba electronic
telephones (2000-, 3000-, 6000-) are used, refer to Worksheet 7.
2. The number of digital telephones with PDIU-DIs is limited by the system’s power capacity per Worksheet 7. Also, DIUs
are limited to slots 01 ~ 10 in DK96 and cannot be connected to Circuit 8 of a PDKU1 but can be connected to Circuit
1 of 8 of the PDKU2.
3. Normally only one PESU is installed in a system that requires a mix of standard and electronic telephone circuits. A PESU
is installed instead of a PSTU if only one or two standard telephone circuits are needed. It is installed instead of a PEKU
if only four electronic telephone circuits or less are needed. The PESU supports the same stations and options as the
PSTU and PESU do, except for the HDSS console.
4. The maximum number of PEMU PCBs is determined by the system's power supply capacity (caution: do not exceed the
numbers shown); also, if a PEMU is installed in a DK24 with a PCTUS1 PCB, only 16 station ports are available for
stations.
5. Only one type of peripheral interface PCB (PIOU, PIOUS, PEPU) may be installed per system.
