Strata DK General Description    6/0025
ISDN BRI Circuit Capacity Guidelines
The tables in this section show the maximum capacities for ISDN BRI circuits using RBUU/
RBUS and/or RBSU/RBSS PCBs. Guidelines 1~7 below apply to Tables 16~19.
1. Each BRI circuit can be configured to support either one BRI (TE or TA) ISDN station; or two 
ISDN line channels.
2. A maximum of eight BRI circuits may be used as BRI line circuits to connect to the ISDN 
Central...

Remote Expansion Cabinet Unit
The RRCU PCB enables a DK424i Expansion Cabinet to be located up to three kilometers from its 
Base Cabinet. One RRCU connects to up to two ribbon-type Data Cables and applies the inter-
cabinet signal to a fiber-optic pair. One fiber pair can support one or two expansion cabinets in one 
remote location using one RRCU in the Base Cabinet and another in the Remote Expansion 
Cabinet.

The lightweight and compact design enables easy wall or floor mounting. The BFIF hardware kit 
is needed for floor mounting (see Ta b l e  2 7). If floor mounting three or more cabinets, AC and 
reserve power must be connected to the BCCB conduit connection box option by a licensed 
electrician. If more than two...
