The Excel switch cabinet is a standard telecommunications rack. It houses one or twoExcel EXS switches, the DC power distribution system and the associated patchingequipment (for 120Ω twisted pair connections only) which allows a point of flexibility tobe afforded in the connection of customer E1 or T1 lines.
The physical dimensions of this rack are:
Width 610mmHeight 1800mmDepth 850mm
The basic cabinet as depicted in the two following diagrams and is fitted out in astandard manner.
3.2.2 Excel switch cabinet equipment
Equipment DescriptionPower distribution system The power is supplied from the customer in a redundant configuration
to the INP power distribution. The power distribution consists of apair of redundant bus bars that supply the output voltage throughbreaker circuits rated at 15Amps.
blanking plate A blanking plate is mounted below the power distribution system,which separates the EXS switches and the power system.
EXS units The EXS units are mounted facing the front of the cabinet to alloweasy access to the Printed Circuit Boards and the remaining space isfilled with brushed aluminium blanking plates.
door The enclosing door is of a smoked Perspex type.
A customer-supplied earth is terminated on the earth bar located at the bottom of thecabinet. From this point a connection is taken to the logical ground of each EXS switchand a connection is taken to the frame of the cabinet.
3.2.3 Configuration of the Excel EXS 2000
A Typical EXS 2000 Non Blocking Programmable Switch comprises:• EXS 2000 Chassis (19 inch rack mountable enclosure)• 2 * EX 2000/CPU (CPU/Switching matrix redundancy) and I/O cards• 2 * SS7 (SS7 signalling redundancy) and I/O cards• 2 * MFDSP (tone and announcement redundancy)• 2 * PSC Power Supply (power supply redundancy)• Up to 8 * n channel line cards (8 x E1/T1 interface) and I/O cards
3.2.4 Functionality of Excel EXS 2000 circuit cards
The functionality of the circuit cards are described briefly below:
EX/CPU 2000 Provides switching functionality for up to 2048 ports, configurationmanagement, and call control
SS7 Provides from 2 to 16 signalling links (depending on the numberrequired)
MFDSP Provides tone generation, tone reception, and announcement capabilitiesN channel E1/T1cards
Provides the interface to the customer's switching network. 4, 8 or 16E1/T1 spans are interfaced per circuit card
Power supply Provides the power conversion from –48V DC to 5V DC
3.2.5 Excel switch networking
Where Excel switches are located remotely to the server machines, it is necessary forhigh reliability data network connections to be provided with the followingcharacteristics:
• Two logical connections between each Excel switch and the server machines,probably diversely routed for maximum resilience
• Connections at both ends are standard 10 base-T Ethernet• Protocol to be transported is TCP/IP• Bandwidth required for each connection is 128kbps. This bandwidth must be
guaranteed and exhibit deterministic delay characteristics• The IP traffic must be ‘bridged’ across the data network because the Excel switches
must be on the same sub-network as the HP servers.
The Excel switch rack does not have to be co-located with the HP servers.
4.1 Allowances for cabinet doors
Allowance must be made for the opening of cabinet doors for internal access to theequipment. It is recommended that at least twice the width of a HP cabinet (1200mm)be allowed at both the front and rear of the cabinet for this purpose.

The floor plan above is for the equipment and working area requirement for single nodeand customer care system.
The Aethos INP is connected in the following configuration. This configuration coupledwith the functionality of the HP Service-Guard software provides for a resilient,redundant system.
It is recommended that a workstation capable of supporting an X windowingenvironment be purchased in addition to the standard hardware. The consoles that aresupplied with the Hewlett-Packard Servers are not considered suitable to support normalmaintenance procedures.The minimum specification for a PC-based workstation should include the following:• Intel Pentium Processor• 32 MB of RAM• 17 inch monitor (easier to manage multiple windows)• LAN interface card (to connect to LAN)• Sound Blaster compatible sound card (to allow recording of announcements if
required)• Windows ‘95 operating system (includes TCP/IP)• a software package capable of supporting UNIX X windows, such as Exceed.
Alternatively, an entry-level UNIX workstation such as the HP 700 series may be used.
The site requirements are detailed in the environmental section. The site is normally acomputer room or a telecommunications switching environment. It is envisaged that thesite will have a raised floor to allow for cable access. All building work must becompleted prior to the delivery of the INP to conform to the dust level requirements.The following cabling is required and is the responsibility of the customer:• 2 x –48v DC power feeds per Excel and as specified in Section 2.4• E1 Cables using standard twisted pair or co-axial cabling• 3 local 240v/110v AC power feeds for each HP rack, independent and of the same
phase• Clean building earth connections for all 4 cabinets• 10 Base - T LAN Connections• One or more telephone connections for support modems (note that modems are not
It is not envisaged that either the HP or Excel components of the INP will requirebolting to the floor.
6.2.1 HP server
The HP servers will be installed and commissioned by representatives of HP or Logica.The AC power requirements for the HP servers are specified in section 2.2.
6.2.2 Excel switch
The Excel switch bay will be installed and commissioned by Logica personnel, with DCpower supplied by customer.The standard telecommunications rack which houses the Excel switch bay will bedelivered to site with as much of the internal installation completed as possible. This isdependent upon local conditions and the availability of country specific components.The DC power supply must be a redundant feed system i.e. two feeds supplied to theExcel switch bay. Each feed must be multi-core cable, a minimum of 6mm2/10American standard wire gauge, a maximum of 10mm2/8 American standard wire gauge,and capable of supplying a nominal 10 Amps.
The physical installation will be completed and the inspection carried out by thecustomer prior to connection of the -48 volt DC supply.It is envisaged that the inspection will cover the quality of the installation, cableterminations, random checks of some of the Printed Circuit Boards and an overallinspection of the Aethos Pre-paid System to satisfy the customer that the equipment is fitfor the purpose.
7.2 Basic commissioning procedures
7.2.1 Earth test procedure
The customer must provide a clean earth point to supply the Excel EXS with a logicearth. This earth will be connected to the earth bar that is provided in the Excel switchbay. The earth should be provided from the main building earth. The resistance betweenthe power supply earth and the building earth must be less than 1 ohm.
7.2.2 Short circuit test Excel EXS
1. Ensure that the power connection into the Excel Switch Bay is not short circuiti.e. there should be an input resistance to the EXS. This should be performed inthe conventional way with a resistance meter testing across the input terminals.
2. If a redundant power configuration is to be utilised this must be performed onboth the input terminals of the EXS after the straps that support a single powersource have been removed.
1. Remove all circuit boards from the mid-plane bus, except the power supplies.2. Ensure all breakers are in the off position.3. Ensure that the correct polarity and the voltage source are present at the
customer power point.4. Close the breakers that feed the Excel switch bay.5. Test the bus-bar system in the Excel switch bay for correct polarity.6. Close the breakers on the front panel of the Excel switch bay.7. Test the terminals on the back of the Excel EXS to ensure correct polarity.8. Power on the master power switches at the rear of the Excel EXS.9. Power on the power supply cards at the front of the EXS. This will cause the
fans to start and will supply DC power to the mid-plane bus.10. Re-seat circuit cards one at a time, starting with CPU A.11. Physically reset each circuit card via the Reset button on the front panel of each
card.
The power up procedure is now complete.
7.2.4 Basic communications testing (internal to Aethos Pre-paid system)
The physical connections need to be provided between the EXS and the HP servers.These connections are made via two of the LAN HUBS that are supplied with theservers.
Note: The DIP switch SW1 located at the top left of the CPU daughter board requiresswitches 1 through 6 inclusive to be set to ON. Switches 7 & 8 should be OFF.
1. All DIP switches on E1 cards must be set OFF.2. All switches on MFDSP and C7 cards should be set ON.3. Give each EXS CPU an IP address. The HP server using the RARPD process
does this. The Ethernet address is taken from the Excel switch CPU card stickerand entered in the correct file on both INP server machines along with theassigned IP address. When the Excel switch is powered up it will ask the serverfor this IP address and use the IP address from then on.
4. If the IP address has been successfully stored on the CPU and the LANconnection is reliable it should be possible to use the UNIX utility ‘ping’ to testfor communication from the HP Servers to the EXS.
5. If it is possible to communicate to both CPUs from both servers then the basicconfiguration should be considered as satisfactory.
