Cabinets

There are three types of cabinet used in INDeX architecture; the 100S Control Unit Cabinet (CABCU 100-S), the Control Unit Cabinet (CABCU), and the Expansion Cabinet (CABEX).

Index 200 Index 400

A fully configured INDeX consists of 5 cabinets, rack or wall mounted. A cabinet consists of: EMC approved metal casing, backplane and front cover and has been designed to offer high modularity, scalability and extensibility.

The CABCU 100-S is a Control Unit Cabinet specifically designed for use with the PSU 4 and CPU 100. Accommodating a maximum of 4 cassettes (ie. CPU 100 plus 3 device Cassettes), this is a stand alone cabinet offering no upgrade connectivity to other cabinets or CPUs in the range.

The remaining two types of cabinets have 8 slots (1-8) and a compartment 0 which is always allocated for the power supply unit. This leaves 8 cassette slots, of which up to 7 are available for device cassettes. The 8th slot of the Control Unit Cabinet is always utilised by the Central Processor Unit (CPU) cassette. The 8th slot of the Expansion Cabinet is always utilised by the Expansion Link cassette (ELC). (The system cassettes are detailed later in this section).

Each slot has a maximum port capacity of 32. The maximum portage available in any one cabinet is therefore 224 (7 slots with 32 ports each). The maximum portage may be reduced according to which device cassette is installed.

For example: the Analogue cassette has a maximum capacity of 24 circuits and thus a cabinet equipped with 2 DASS cassettes and 5 Analogue cassettes would have a total capacity of 180 ports.

These CABCU and CABEX are identical in appearance, size and weight except that the Control Unit Cabinet has 4 RS232 (or V24) ports for connection of peripheral devices, 1 external Music on Hold jack and 1 parallel port reserved for future developments. Each cabinet requires a power supply of which there are two variants. Each power supply requires its own mains supply. The Control Unit Cabinet comes equipped with an approved moulded mains cable with plug and a pre-wired RS232 cable which supports up to four RS232 ports.

The new style cabinet is shown to the right.



The Operator Console 
The NOCpro Networked Operator Console is based on Microsoft Windows, and the console is driven by the Computer Telephony Integration (CTI) link on INDeX. The use of Windows enables the console to be driven via dedicated keyboard keys or point and click mouse buttons. Used in conjunction with one of the INDeX terminals to provide headset and/or handset functionality, the NOCpro provides detailed information in a clear, simple format. A maximum of five NOCpros are supported on the INDeX system.

The Network Operator Console (NOCpro) is based on a client server architecture. The Operator Consoles are NOCpro Clients enabled as a PC client application connected across an ethernet LAN to the server, which is connected directly to INDeX. The server can support a maximum of five clients simultaneously. However, there is no limit to the number of PCs that can be loaded with the NOCpro Client software. Each NOCpro Client uses an INDeX terminal to support handset and/or headset for speech purposes. The console provides all of the primary functionality required to facilitate smooth call handling through the following features: 
Graphical presentation of information giving visual indication of the number of calls queuing 
Simple keyboard operation with keys labelled in the chosen country language for ease of operation 
Three external call queues, recall queue, ring announce answer queue and internal queue to enable the operator to answer the appropriate queue without delay 
All information and messages displayed in the chosen country language text to avoid confusion 
Automatic queuing in order of longest waiting per call queue 
Answer next key to answer longest waiting call 
Wait timer displaying wait time of longest waiting call in each queue 
Large displays (A and B Side) for exchange line and extension information 
At all times the operator has the correct information in order to prioritise call handling and give the appropriate response to the caller, whilst maintaining visibility of the number and type of calls waiting. 
The customer's business will benefit from the improved operator service given by the NOCpro, ensuring clients are greeted in a timely and professional manner, enhancing the image of the company. 
NOCpro Hardware Specification 
The operator console is a PC based product and may be shipped on a Lucent supplied PC. 
Shipped as a pre-configured unit it can be installed on any customer site. It connects directly to the INDeX Control Cabinet via one of the RS232 ports or in conjunction with CCM and the INDeX Voice Manager directly to the CT Server Cassette. The PC works in conjunction with a dedicated 20 Series terminal which can offer headset and/or handset functionality. 

PC Based Products 
There are 4 PC based products available on INDeX: 
NOCpro (Networked Operator Console) 
INDeX Voice Managers (including Premier and Lite) 
INDeX Call Centre Modules 
Windows Call Centre Client 
These are currently shipped on an INDeX PC platform. The specification of the PCs within the INDeX range is constantly reviewed to enable a single common platform for all PC products.

Power Requirement and Heat Output 
The PSU 4 and PSU 8 both require mains voltage to be 220-240V nominal +/-10%, that is, 198V minimum to 264 maximum, 50Hz nominal, 46-63Hz. The maximum current from the mains will be 1. 3A for the PSU 4 and 3A for the PSU 8. 
For Uninterruptable Power Supply (UPS), the PSU 4 requires a 250VA unit and the PSU 8 a 600VA unit. For further details on UPS see Uninterruptable Power Supplies (UPS's) . 
A fully loaded cabinet using the PSU 4 (4 cassettes in total) will dissipate up to 150W maximum. 
A fully loaded cabinet using a PSU 8 (8 cassettes) will dissipate up to 355W maximum. These figures are dependent on correct installation of cabinets as detailed in the Installation Manual.
