1. There are four universal slots in the DK40i expansion unit.
2. In the D40i, DID, Tie, and BRI lines do not use up station ports as in DK40 and the DK424, R4. Each BRI line circuit
uses up to two CO lines of system capacity.
3. Each S/T type circuit requires an NT-1 device when connected to a Central Office BRI line circuit.

1. The DKT2004-CT and DKT2104-CT cordless telephone connects as either a stand-alone or to a digital 2000-series
telephone.
2. Speaker OCA, PDIU and RPCI capacity is determined by PDKU 2B channel slot availability and power supply
limits.
3. To install the maximum of 28 total DKTs and EKTs, up to 16 of the stations can be EKTs and at least 8 of the stations
must be DKTs.
4. In the DK40i, BRI station circuits do not use up CO line numbers as in the DK424, R4. Each BRI station circuit uses
up to two station ports of system capacity. Toshiba BRI (S/T) station circuits are passive and allow up to two devices
to share a circuit. BRI-U allows one device per circuit.
