3. Determine the actual PEKU PCBs required using Charts 1 and 2 as follows:
Actual PEKUs (BT) = (Bm) or (B1) or (B2), whichever is the largest number.
4. PESU: In a configuration that requires less than five electronic telephone
station ports, a PESU PCB may be used in place of a PEKU PCB. The PESU
supports all stations and peripherals that the PEKU and PSTU support, except
for the HDSS console. Normally, only one PESU is installed in a system (see
PSTU, Worksheet 3).
