CTX670 Remote Expansion Cabinet

CTX670 Remote Expansion Cabinet

A CTX670 Expansion Cabinet can be located up to three kilometers from its Base Cabinet. Remote Expansion Cabinets are enabled by the RRCU PCB. One RRCU connects to up to two ribbon-type Data Cables and applies the inter-cabinet signal to a multi-mode 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 CTX670 Base Cabinet supports up to six Remote Expansion Cabinets (at least one RRCU PCB is required for each remote location).

Remote cabinets support the BIOU for external Page Zones, Night Bell, etc., and all CO line and trunk interface PCBs. Network clock synchronization can only be derived from digital trunks installed in the Base Cabinet (Master) location.

System Capacities

This section contains Strata CTX100 and CTX670 capacities for stations and peripherals, CO lines, station buttons and system features. All tables apply to both systems unless otherwise noted.

Important! The maximum capacities listed for the CTX100 in Tables 2-3~2-7are based on an expanded CTX100 (Base + Expansion cabinet).
