(lines + stations)
1. There are four universal slots in the DK40i expansion unit.
2. All CO line capacities assume a PIOU, PIOUS, PEPU, RSSU, or RSIU is installed for RCTUBA/BB, RCTUC/D or RCTUE/
F, but no Caller ID RCIU2/RCIS PCBs.
3. Limits apply to analog DID and Tie lines, not T1 DID/Tie lines.
4. T1 lines can be loop start, ground start, Tie, or DID (maximum 24 lines per unit, any type or combination).
5. BRI lines provide CO line services, including Caller ID, DID and Direct Inward Lines (DIL).
6. PRI lines provide CO line services, including Caller ID, ANI, DID, Tie, POTS, FX and DIL.

1. ISDN BRI TE-1 and TA include ISDN telephones, modems, video conference interfaces, etc. Up to two stations (TE-1 and/or
TA) can connect to and share one BRI S-type circuit. Only one station can connect to a BRI U-type circuit.
2. Speaker OCA, PDIU and RPCI capacity is determined by 2B channel slot availability and power supply limits.
3. To install the maximum of 28 total DKTs and EKTs in the DK40i, up to 16 of the stations can be EKTs and at least 8 of the
stations must be DKTs.
4. Maximum capacity of DKT/EKT stations per DK424 cabinet is 62, less for EKT 2000, 3000 (Power Factor limitation).
