EOCU CARD

3.1.7.1 PRESENTATION
The EOCU card is an equipment card with 4 T0/S0 interfaces. These interfaces must
always be configured as S0. They are configured by MMC only (using the programming
console). This card also allows the connection of four 2-channel DECT radio base stations,
or four 4-channel DECT radio base stations if the EOCU card is fitted with two ADPCM
cards. Insert this card into connector J3 on the OCZ card.

If a DECT radio base station is fitted on the CPU card S0 interface, you must use three
pairs.
Where the synchronization wiring uses a third pair, set CA1 switches to the E position on all
EOCU cards.
