Base/Expansion KSU Compatibility
Station, Exchange Lines, and Stratagy DK Voice Mail
The optional DK40 Expansion KSU has four universal slots which can support Exchange, tie
lines or ISDN PRI and BRI (TE or NT) circuits, stations and option interface PCBs. PCBs
that support lines and can be installed in the expansion unit are the PCOU,RPTU,RBSU (TE),
PEMU, or PACU (see Table 1-2).
PCBs that support stations and can be installed in the expansion unit are the PDKU2, PEKU,
PSTU2, RSTU2, RBSU (NT) and RBSS (see Table 1-2). PCBs that can support optional
interfaces i.e. SMDR, a local or remote DK Admin Personal Computer and Door Lock
control are PIOU, PIOUS and PEPU (see Table 1-3). Placement of the above PCBs must
follow the configurations shown in Table 1-11.
The Stratagy DK voice mail provides 2~8 voice mail/auto attendant ports.
