1. Each BRI circuit (S/T and/or U-type) provides two B channels plus one D channel and reduces the system
capacity by two station ports and two CO lines. Each (S/T) BRI station circuit allows up to two TE-1 and TA
devices to share the BRI B channels (two simultaneous calls maximum per BRI circuit.). Each BRI-U circuit
supports one TE-1 or TA device.
2. Maximum BRI capacity
3. Conventional stations include Toshiba digital and electronic telephones, or attendant consoles, standard
telephones and devices.
4. BRI S/T circuits are available with RBSU/RBSS PCBs and BRI-U circuits are available with RBUU/RBUS
PCBs. ISDN BRI PCBs will be available with a future release of DK424 software. Each BRI line circuit (S/T
or U) provides two BRI CO lines (channels) for incoming/outgoing calls
5. Conventional lines include analog and digital (T1 or PRI) loop start, ground start, DID, and Tie lines.
Power Requirements
Each Base and Expansion Cabinet houses a power supply that generates ±5VDC and -24VDC
which furnishes power to all of the stations and some of the peripherals that interface with the
cabinet. A fully loaded Strata DK424 requires an input power source of 115VAC ± 10VAC
(105VAC ~ 125VAC), 17.5 amps., 50/60 Hz. (see
