TOSHIBA CIX200 PCBs

Two circuit cards are specific to the CIX200 systems; the LCTU processor card and the LSLU, a two-circuit, single-line, telephone interface card. The MIPU24 IP interface card with 24 channel works with the CIX200. The LIPU, an IP interface with 16 resources expands to 32 with the LIPS expansion card and works on all CIX systems.

PCB Option Considerations

Strata CIX 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.).

Some PCBs must have hardware options, such as jumpers or switches, set prior to installation of the PCB in the cabinet.

Common Control Processor Unit (LCTU)

The system operates with the LCTU processor PCB that installs in a dedicated slot of the Base Cabinet. The Strata CIX200 processor has the following standard components built in:

Optional subassemblies can be added to the LCTU processor PCB to enable system expansion and provide additional features. The subassemblies are:

BSIS interface PCB attaches to the LCTU to provide up to four RS-232 interface ports for SMDR Call Accounting, and SMDI or Toshiba Proprietary Voice Mail interface.

AMDS (Modem) – Provides a 33.6Kbps/V.34 modem for point-to-point local or remote connection to the eManager administration PC.

Analog Standard Station Interface Unit (LSLU1A)

The optional 2-circuit LSLU card provides for connection of two analog devices, such as faxes, modems, standard telephones, etc., without message waiting. The LSLU installs into a dedicated mount in rear of Strata CIX Base Cabinet behind the processor slot. The LSLU does not occupy any of the universal slots of the cabinet, so it does not reduce the maximum capacity of the system. The two analog station ports are accessible on the front of the base cabinet via modular connectors.

Modular or Amphenol Connections

The Strata CIX200 provides a choice of using either RJ45 modular connectors or amphenol connectors for terminating CO line and station interfaces.

Modular RJ45 connectors are provided by adding optional extenders and modular faceplates to CIX interface cards used in the Strata CIX200. This enables the modular interface cables to be connected at the front panel of the CIX200 cabinet.

Amphenol connectors are provided by using CIX interface cards in the Strata CIX200 without

extender cards. In this configuration, amphenol interface cables are routed through the side of the cabinet and a flat face plate covers the slot housing the card. See the Strata CIX Installation and Maintenance Manual for more details on Modular or Amphenol connections.

The Strata CIX200 supports two different types of optional extenders for the other CIX interface cards, depending upon the type of connectors that exist on the card.

Extenders

The CIX system uses two types of extenders. One type is connected between the interface card and the cabinet backplane. This type of extender brings the interface connectors to the front of the cabinet. The correct front plate for the interface card is packaged with the extender. These extenders are optional.

The second type of extender plugs into the interface card front connector and presents different

connectors to the front plate. Some of this type are optional, such as the extender that connects to the 25-pair Amphenol connector on the station card and presents eight or 16 modular connectors to the front panel. Refer to Table 8.

Power Failure Transfer Unit (LPFU1A)

The optional 8-circuit LPFU card when used with the RCOU and RSTU cards can automatically connect the CO line circuits to the Single Line Telephones (SLT) when system power fails. The LPFU card installs onto the CO line card as an extender, so it shares the same cabinet slot. The RCOU card must be in the slot above.

The Strata CIX670 system provides sophisticated

telecommunication features in a modular system designed for growth. Its universal slot architecture enables you to select the combination of Central Office (CO) lines, stations, and peripheral options that best suit your needs.

The CIX670 BCTU basic processor can be configured for smaller systems as a one or two cabinet system with a capacity of up to 192 CO lines and stations combined. It can expand to support up to seven cabinets with a capacity of up to 672 CO lines and stations combined

with the BCTU/BEXU expanded processor (see Figure 6).

System line and station capacity is expanded by adding processor expansion Circuit Cards, cabinets and line/ station circuit cards and station/line licenses.

The CIX670 easily connects to outside public and private telephone lines. All of the telephones (stations) tied to the system can have direct access to each other as well as to the public and private network.

The Base Cabinet and optional Expansion Cabinets are the building blocks of the system. Each system has a Base Cabinet, and can have from one to six Expansion Cabinets. All lines, stations, and options are tied together through the cabinets.

The overall weight and dimensions of the CIX670 cabinets are shown in Table 9. Table 9        CIX670 Cabinet Specifications
