UNIVERSAL SLOT/PCB CAPACITIES
1. The appropriate capacities apply to 1 OOO-series digital and 6500-series electronic telephones only.
if other Toshiba electronic telephones (2000-, 3000-, 6000-) are used, refer to Paragraph 1.12.
2. The PESU provides two standard telephone circuits identical to PSTU circuits and four electronic
telephone circuits identical to PEKU circuits. Normally only one PESU is installed in a system that
requires a mix of standard and electronic telephone circuits. A PESU is installed instead ofa PSTU,
if only one or two standard telephone circuits are needed. A PESU is installed instead of a PEKU
if only four or less electronic telephone circuits are needed, The PESU supports the door phone
option and the BGM source but not DSS consoles.
3. The maximum number of PEMU PCBs is determined by the system's power supply capability
(caution: do not exceed the numbers shown); also; if a PEMU is installed in a DK24 with a PCTUS
PCB, only 16 station ports are available for telephones.
4. Only one type of peripheral interface PCB (PiOU, PIOUS, PEPU) may be installed per system.
5. The number of digital telephones with PDIU-Dis is limited by the system's power capacity per
Worksheet 7. Also, PDIU-Dis are limited to slots 01 N 10 in DK96 (see Table 4-B for details).
