PXML No. BABT/PXML/CRA.0020/0021/0022 APPROVAL No's. 210/220/230 - NS/3343/123/N/603533 / NS/3343/123/N/603532 / NS/3343/123/N/603538 The PABXs are Electronic, Digital, Stored Programme Controlled employing Time Division Multiplexing to establish connections and A Law Pulse Code Modulation for local voice transmission. The standard attendant equipment comprises an attendant's (Operator's) console, an attendant interface card (ATTI) and an extension line card (PLCC). These cards are located in the Peripheral Equipment Modules (PEM's). In the event of power or major equipment failure, predetermined extensions are connected to the Public network. The power fail extension telephones must be provided with Earth recall to ensure continued operation after power fail. In the case of systems fitted with DDI lines, these can be connected to a call answering machine in the by-pass emergency mode. The Omni range supported numerous type of attendant consoles. For information on early consoles see NTX30. The Omni 200 range only used the Level 3 console. This was an enhanced Level 2 with a Disc Operating System and greater on board memory. OMNI 210 The system comprises a single cabinet and a TJF to which the cables from the PABX are terminated. The cabinet contains a mains power supply, one or two ringing generators and a shelf assembly (file) to house printed wiring cards. The file contains 36 card slots allocated as follows: 10 slots for dedicated control cards 1 slot for power cards 2 slots for digital links 23 "Universal" slots Universal slots can hold any peripheral card (e.g. Extension or CO) OMNI 220 The system comprises a single cabinet and a TJF to which the cables from the PABX are terminated. The cabinet contains a mains power supply, one or two ringing generators and two shelf assemblies (files) to house printed wiring cards. Each file contains 36 card slots allocated as follows: 10 slots for control cards 1 slot for power cards slots for digital link cards 23 "Universal" slots Universal slots can hold any peripheral card (e.g. Extension or CO) OMNI 230 The system comprises one or two cabinets, depending on the number of lines required. Additional cabinet(s) may be needed for housing batteries for back-up purposes. The system is 48V powered and an external rectifier unit is needed. Each equipment cabinet contains up to five shelf assemblies (files) to house printed wiring cards. The files are referred to as Common Equipment Module (CEM) or Peripheral Equipment Module (PEM). A CEM contains the control cards needed to run the system. A PEM contains the peripheral cards (e.g. extension and trunk cards). A system normally contains one CEM (SIMPLEX) but it is possible to have a second CEM as Standby in case of a failure of the primary CEM (DUPLEX) SYSTEM CAPACITIES The maximum capacities for the OMNI 200 Series are as follows: OMNI 210 OMNI 220 Extensions 256 512 Trunks * 92 184 Digital Links 2 4 OMNI 230 1 CEM/4 PEM 1 CEM/8 PEM Extensions 1024 2048 Trunks * 512 1024 Digital Links 8 16 * Trunks include exchange lines DDI and Private Circuits. The OMNI 200 range was made by ATEA. |
