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 eight 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.
