Strata CTX670 Installation

Install Processor and Universal PCBs

Step 7: Install Processor and Universal PCBs

This section provides procedures for the installation of CTX670 processor (or common control) PCBs.

The CTX670 system Base and Expansion Cabinets are shipped empty. PCBs are not installed at the factory. Universal PCBs must be placed according to the configuration information obtained and developed in Chapter 1 – Configuration. PCB installation is in Chapter 6 – PCB Installation.

•Install PCBs only after installing the Base Cabinet and, if applicable, Expansion Cabinets per the Cabinet Installation section in this chapter.

•Be sure the power supply has been tested and the ground has been checked (see “Install Power Supply” on page 4-6.

•Install universal slot PCBs per the CTX670 configuration guidelines (see “Worksheet 6: Strata CTX670 Cabinet Slots” on page 2-37.

•Install the metal mesh shield, B50MT around the 25-pair cables connected to PCBs per Figure 4-10.

Important! After all PCBs are installed, be sure to slide the locking bar into the lock position to ensure that the PCBs remain in place (see Figure 4-3 on page 4-9).

PCB Installation Considerations

The Base Cabinet has ten slots. The first two slots, labeled “B101” and “B102” are reserved for the common control unit and future feature upgrades. The next eight slots (labeled “S101” ~“S108”) are universal and capable of hosting any of the station, line, and option interface PCBs compatible with the CTX670 systems.

The Expansion Cabinets have ten universal slots, labeled “S_01,” “S_02,” etc., where the blank space of the label represents the number of the Expansion Cabinet. Like the universal slots in the Base Cabinet, these universal slots are capable of hosting any of the station, line, and option interface PCBs.

Cabinets are numbered from 1 to 7. The Base Cabinet is numbered 1; the first Expansion Cabinet, number 2; the second Expansion Cabinet, number 3, etc. See the CTX670 Configuration and PCB Installation section for details.

PCB Option Considerations

CTX670 PCBs can be configured for a variety of hardware and software options. Hardware options are defined as either internal (generally related to optional PCB subassemblies) or external (related to connection of peripheral equipment such as background music, voice mail, etc.).

Hardware Options

Some PCBs must be configured for hardware options prior to installation of the PCB in the cabinet. Configuration instructions for internal hardware options are provided in the individual PCB installation procedures in this chapter and in Chapter 6 – PCB Installation. Configuration instructions for external hardware options are provided in Chapter 12 – Peripheral Installation.

Software Options

PCBs are configured for software options through programming, following the installation instructions of the PCBs. A programming overview for each PCB is provided in the individual
