Software Feature Cartridge

• The Feature Cartridge contains the system software for the Modular ICS's operation, including the call processing, administration, and maintenance features and functions.
• The two-piece cartridge introduced with
• Modular ICS Release 4.0 contains expanded RAM and system software on a PCMCIA card.
• Customer data (RAM) is stored on the ICS and is preserved during software upgrades and power outages.
• Four versions of software are available:

 NA-Modular ICS-DR 4.1 Expanded feature capability. Replaces Release 4.0. Supports up to 6 expansion modules.

CDA-Modular ICS-XC-4.1-Expanded capability and Companion wireless functionality. Available in Canada. Supports up to 12 expansion modules.

USA-Modular ICS-XC-4.1 - Expanded capability and Companion wireless functionality. Available in the US. Supports up to 12 expansion modules.

Release 1, Centrex- Provides transparent operation of popular Centrex features. It does not support T1, ISDN-PRI, ISDN-BRI, Companion or expansion beyond 6 ports.

Compact ICS Interface Cartridges  LS/DS Analog Trunk Cartridge

• Provides access for up to four Central Office analog lines.
• All LS (Loop Start)/DS (Disconnect Supervision) Trunk Cartridges have Disconnect Supervision capability and are labeled "DS'' on the faceplate.
• Also called the New DS Loop Start Trunk Cartridge.
• Compatible with the Modular ICS core, Fiber and Copper Trunk Modules, the Compact ICS core and the Modular 8x24 Copper Trunk Module.

Caller ID Analog Trunk Cartridge

• The Caller Identification (CI) trunk Cartridge has the same functionality as the LS/DS Trunk Cartridge but with the additional capability to detect and translate incoming CMS/CLASS information for display on Norstar sets.
• The CI Trunk Cartridge is required when any CMS/CLASS lines terminate on the Compact ICS core or the Modular ICS core or trunk modules.
• Provides access for up to four Central Office analog lines.
• Compatible with the Modular ICS core, Fiber and Copper Trunk Modules, the Compact ICS core and the Modular 8x24 Copper Trunk Module.

2-Port U Interface ISDN-BRI Cartridge

• Supports two ISDN-BRI U Interfaces per cartridge.
• Integrated Network Termination Type 1 (NT1) functionality.
• Interfaces can be individually configured to be a network interface or a station side equipment interface.
• Powered by the cartridge slot connector.
• LED on cartridge faceplate gives visual indication of circuit status (activated or deactivated).
• Compatible with Compact ICS core and Modular ICS core and Fiber Trunk Module.
• Requires Services Cartridge or Combination Services Cartridge on Compact ICS.
• Requires either the Services Cartridge or the Combination Fiber 6 port Services Cartridge on Modular ICS.

Compact ICS Clock Services/Expansion Cartridges

Services Cartridge

• Provides clocking for ISDN-BRI circuits.
• Only required if using ISDN-BRI cartridge; and 16 or fewer stations.
• Installs in the Expansion Card slot in the core unit.
• Compatible with Compact ICS only.

Combination Services Cartridge

• Provides clocking for ISDN-BRI circuits and expansion from 16 to 24 station ports.
• Required for TCM port expansion.
• The Combination Services Cartridge replaces the 8-Port TCM Expansion Cartridge that is no longer available.
• Compatible with Compact ICS only.

Fiber Expansion Cartridges

• Two or six-port Fiber Expansion Cartridges connect additional Fiber Trunk, Fiber Station, or Analog Station Modules to expand core Modular ICS capacity.
• The Fiber Expansion Cartridges fit into slot 2 (a half-width slot) of the ICS. The other half width slot (slot 1)is reserved for the Services Cartridge.
• With XC software, two Six-Port Expansion Cartridges can be installed in the Modular ICS, the first in Slot 2, the second in Slot 1.
• Compatible with the Module ICS core only.

Copper Expansion Cartridges

• Two or six-port Copper Expansion Upgrade Cartridges can be used in an upgrade scenario to connect existing Copper Trunk and Station Modules to the Modular ICS.
• Modular ICS Copper Expansion Cartridges are twice the width of Fiber Expansion Cartridges. They fit into slot 1 (a half-width slot) but also cover slot 2 of the ICS.
• Compatible with the Modular ICS core only.
• The use of Copper Expansion Cartridges and Copper Trunk and Station Modules precludes the use of T1, ISDN-PRI, ISDN-BRI and Companion, and limits the growth of the Modular ICS to 6 expansion modules.

Combination Fiber 6-Port Services Cartridge

• The Modular ICS Combination Fiber 6-Port Services Cartridge connects additional Fiber Trunk and/or Station Modules to expand the core capacity of a modular ICS equipped with XL or XC software to a maximum of 12 expansion ports (272 total ports maximum configuration).
• This cartridge also contains the clocking service required to support T1 or ISDN-PRI on the DTI cartridge or an ISDN-BRI Cartridge.
• The Combination Fiber 6-Port Services Cartridge fits into slots 1 and 2 of the Modular ICS and works with XC software, and regular DR 1.1 and later software. Requires fiber connections.
• Compatible with the Modular ICS core only.

Services Cartridge

• Provides the clocking service necessary for digital networks.
• Required if using DTI cartridge(s) or ISDN-BRI Interface cartridge(s).
• One services cartridge supports all clocking required, regardless of the number or mixture of DTIs and/or ISDN-BRI Interface cartridges.
• Uses Slot 1 of the core ICS and cannot be used if a Copper Expansion Upgrade Cartridge is installed.
• Compatible with the Modular ICS core only.

Digital Trunk Interface Cartridge

• The Digital Trunk Interface (DTI) Cartridge provides access for up to 24 digital T1 or ISDN-PRI channels. It comes equipped with built-in Channel Service Unit (CSU) functionality to support the integrity of digital signaling.
• The core Modular ICS can support up to two DTIs for a total of 48 T1or ISDN-PRI (digital) lines. DT1s cannot be installed in Trunk Modules.
• Requires either the Services Cartridge or the  Combination Fiber 6-Port Services Cartridge.
• Compatible with the Modular ICS core only.

ISDN-PRI Enabler Soft Key

• The ISDN-PRI Enabler Soft Key is required in order to configure the Digital Trunk Cartridge (DTI Card) as a PRI card.

4-Port U Interface ISDN-BRI Cartridge

• Supports Four ISDN-BRI U-Interfaces per cartridge.
• Integrated Network Termination Type 1 (NT1) functionality.
• Interfaces can be individually configured to be a network interfaces or station side equipment interfaces.
• Powered by the catridge slot connector.
• LED on cartridge Faceplate gives visual indication of circuit status (activated or deactivated).
• Compatible with Compact ICS core and modular ICS core and Fiber Trunk module.
• Requires Services Cartridge or Combination Services Cartridge on Compact ICS.
• Requires either the Services cartridge or the Combination Fiber 6 port services Cartridge on Modular ICS.
