Dk40I Isdn - Toshiba DK14 Installation And Maintenance Manual

DK40i Configuration
Configuration Considerations
6. Speaker OCA and RPCI/DIU data applications can only be installed on digital telephone ports
in the DK40i Base KSU and slots 15 and 16 of the DK40i Expansion KSU (24 maximum).
7. RWIU can be installed in any of the expansion cabinet slots (15, 16, 17, and 18) to support up
to 8 StrataLink handsets. If there are 9 to 16 handsets, the RWIU must be installed in slot 15
and slot 16 must be vacant. This system cannot support 24 or 32 handsets because of a port
limitation.
8. RDTU can provide 8 or 12 T1 lines – software programmable. Install RDTU in slot 15. Slots
16, 17, and 18 can be used for other PCBs.

DK40i ISDN

Configure DK40i, ISDN BRI PCBs (RBSU, RBSS, TBSU and TBUU) with the following rules
1. TBSU or TBUU installs in the base cabinet to provide 2 BRI circuits, each circuit can be
station side or line side in any combination. See the ISDN section in this manual for more
information regarding TBSU and TBUU.
2. If a TBSU or TBUU is installed, TDDU or TCOU cannot be installed. Only one PCB (TSBU,
TCOU or TDDU) can be installed in the DK40i base cabinet for a given DK40i configuration.
3. RBSU or RBUU installs in any expansion unit slot to provide 2 BRI circuits which can be
station side or line side in any combination.
4. RBSS installs on an RBSU and RBUS install on an RBUU in any expansion unit slot; each
PCB combination provides 4 BRI circuits total. RBSS can be station side only; RBSU can be
station or line side.
5. Each ISDN BRI circuit uses two station ports and no line numbers if the circuit is configured
for station side. This is different from the DK424 ISDN in which each BRI circuit uses two
station ports and two line numbers when the circuit is configured for station side.
6. Each ISDN BRI circuit will use two line numbers and no station ports if the circuit is
configured for the line side. This is different from DK424 ISDN, in which each BRI circuit
uses two station ports and two line numbers when the circuit is configured for line side.
7. Total maximum BRI circuits on the station side is 10 (20 ports/B-channels max.).
8. Total maximum BRI circuits on the CO line side is 6 (12 lines/B-channels max.).
9. RPTU can provide 8 or 12 PRI lines – software programmable. Install RPTU in slot 15. Slots
16, 17, and 18 can be used for other PCBs.
