Technician's Handbook
A seven cabinet system with a MCC IIIEL card and two CFCIII cards
provides a system for low traffic configurations such as a hotel/motel
environment.
The SX-200 EL and the SX-200 ML systems use the SX-200 ELx
cabinet for the main control cabinet and the peripheral cabinets.
Located on the rear of the cabinet are connectors for T1 trunks (J5 and
J6), connectors for PRI maintenance (J10 and J11), a printer port, a
maintenance terminal, and the SFT (System Fail Transfer) control port.
