The exceptional versatility of the X-900 telecommunications test station is further enhanced by the X-930 Caller ID option. This user-friendly hardware option allows either UK or US formats of Caller ID to be accurately simulated and it confirms Electron Parametrics' philosophy of providing a one-stop solution for the telecommunications, production testing environment.
Flexibility: For testing to many international standards
User-friendly: Easy and fast in use for maximum productivity
Added Value: Further enhances capability of X-900
Quality: High quality build for reliability and long life
The hardware is in the form of an external unit and contains a programmable modem and a digital attenuator. Along with the X-900 custom Caller ID software, these give the user precise control over timing, level and data parameters, including the message checksum which may be deliberately altered to simulate an error. The set-up screens of the custom software are laid out in a way which mimics the phases of transmission of a caller ID message.
A particular message format can then be realised by enabling or disabling certain phases of the sequence, for instance the UK format needs no initial ringing burst so this is disabled, but it does need line reversal and an alert tone, both of which are enabled.
The equipment has been proven on Caller ID devices which meet BT Suppliers Information Note 242, the US Bellcore specification and Proprietary Cable TV specifications. Other formats are available on request.
Data Carrier format: Selectable, V.23 or Bell 202
Comms parameters: Fixed 1200 baud, no parity, 8 data bits, one stop bit
Initial line reversal: Optional
Initial ring burst: Optional, timed to nearest 10ms, parameters as per X-900 synthesiser ringing
Pause after initial event: 0-10 secs in 10ms steps
Alert Tone: Optional, uses X-900 PSG, dual frequencies to nearest 1Hz, level adjustable up to approx. 0dBm, duration 0 to 1 sec. in 1ms steps
Pause after alert tone: 0-1 sec. in 1ms steps
Channel seize: Duration defined by no. of bytes sent, range 0- 1000 bytes
Mark tone period: 0-1 sec. in 1ms steps
Pause before ringing: 0-10 secs in 10ms steps
Final Ringing: Uses X-900 standard ringing parameters (synth ringing)
Data transmit level: Programmable in 0.375dBm steps up to 0dBm max.
Source impedance: X-900 internal or external load (selectable)
Checksum generation: Automatic or manual (to force an error)
