3
Each PEB connection requires one D/320-SC card.

You must terminate the PEB at both ends to ensure proper electrical
characteristics. The ACL-60 has built-in PEB terminators, so you must
install the ACL-60 at one end of the PEB cable. You must remove all
PEB terminators from the resource cards (TTS, VR, Fax) on the PEB.
5
The ACL-60 uses shared memory range E0000 to EFFFF.

Only one ACL-60 card per system is allowed.
