MICRO SEVEN, INCâ provides 16 or 32 port telephone line simulator, model PC300-16AD and PC300-32AD
Micro Seven-MINI-PBX SIMULATOR, model PC300-32AD is shown in the above picture.
MINI-PBX SIMULATOR, models PC300-16AD, 16 port, and PC300-32AD, 32 port, provides 16 or 32 simulated telephone lines in a 19-inch rack-mount configuration with 20 Hz ring signal and multi-line DTMF dialer, which enables all lines to dial in DTMF mode simultaneously. Telephone numbers are common number+2-digit line number. It contains LED display showing off-hook or ringing state for all lines. AUX SWITCH 1 on the front panel is provided to increase insertion losses with random noise between all lines to enable modem-testing for low input signal conditions. AUX SWITCH 2 selects switching circuit mode between analog and digital. In the analog switching circuit mode, signals between lines are not converted to digital forms; therefore, signals do not contain A/D noise or quantization noise. Telephone calls between two adjacent lines are only permitted in the analog mode. In the digital switching circuit mode, signals between lines are routed through analog to digital and digital to analog converters, and the signals contain quantization noise. In the digital switching circuit mode, telephone calls between any lines are permitted. The PC300-32AD may also be used for table-top or 19-inch rack-mount use. The call progress tone is either dual frequency call progress tone or single frequency tone with control software selectable. With RS232 interface and provided control software, stutter dial tone, PBX mode, disconnect signal, network delay, analog/digital mode, random noise amplitude, and telephone number are programmable. For custom configuration options, line impairment option may be installed. PC300 includes RS232 interface for Serial port interface and programming software are included as standard features.
Phone Number is programmable by control software, and it is (common telephone number)+two digit line number.
DTMF Dialing: -13 dBm to +5 dBm per a single frequency ;no more than 4 dB difference between frequencies.
DTMF Dialing Detecting Time: 45 ms
Pulse Dialing (10 pulse per second):
Break Period: 45 to 75 ms (60 ms nominal).
Make Period: 30 to 60 ms (40 ms nominal).
Multi-Line DTMF Dialer: all lines contains multi-line DTMF Dialer capabilities, and it allows all lines to dial in DTMF mode.
DAA Impedance Requirement:
240 ohms maximum DC, 600 ohms nominal AC
Input Impedance at 1 k HZ: 600 ohms +/-5%
Signal Range: -45 to +5 dBm
Signal Bandwidth: 150 HZ to 4 k HZ
AUX SWITCH 1/2
Caution: front panel switches is disabled by control software setting.
Insertion Loss between lines is 2 dB when the AUX SWITCH 1 is down. It is 22 dB when the AUX SWITCH 1 is up.
Analog switching mode when the switch is up, and digital switching mode when the switch is down.
Caution: Telephone calls between two vertical RJ11-C connectors, i.e. between line 11 and 12 are permitted in the analog switching mode.
In the analog switching circuit mode, signals between lines do not go through A/D and D/A converters, so the signals don't have quantization noise. In the digital switching circuit mode, Because signals between lines are routed through analog to digital and digital to analog converters in digital circuit mode, the signals contain quantization noise. In the digital switching circuit mode, telephone calls between any lines are permitted.
PBX Battery Feed Voltage: -30 V minimum
Stutter dial tone/continuous dial tone: Selection is controlled by software. Continuous dial tone is factory standard.
Disconnect signal: Disconnect signal is the interruption of loop current when a called line goes on-hook. The value of disconnect signal is programmable by the control software.
Network delay: Time delay is provided after the end of dialing before a called line receives ring signal. The value of network delay is programmable by the control software.
Control software: The software, pc300.exe, is Windows compatible, and it communicates via RS232 interface.
The screen shot is displayed below:
90 Volts RMS, 20HZ, 2 sec on/4 sec off
Maximum Load: 5.5 K ohm (equivalent to 1.45B of Ringer Equivalent Number). Note: Overloading any line will cause problems in all other lines.
Tones: selection between dual frequency or single frequency (480Hz) is made by the control software for EEROM.
Duration: .5 sec on, .5 sec off for busy tone, 2 sec on /4 sec off for ring-back tone, or continuous for dial tone.
Selection between continuous dial tone or stutter dial tone is also made by the control software.
Signal Power: -20 dBm nominal
Line Input Jack: USOC-RJ11C, standard modular phone jacks.
AC Power Switch: Located on the rear panel.
AC Power Connector: Located on the rear panel.
Power Requirements: 110-130VAC, 50/60HZ, 100 Watts maximum
There are two fuses to protect PC300: Main Fuse and PBX Power Supply Fuse: The PBX Power Supply Fuse protects PBX battery-feed supply, and the Main Fuse protects a switching power supply inside PC300. When the Main Fuse blows, the PBX Power Supply also shuts down.
Main fuse: 1 A, 3AG, SLO-BLO
PBX Power Supply Fuse: 0.5A, 3AG, SLO-BLO
Line Status Display:
Red LED display for each line is provided to show off-hook state (steady on) or ringing state (blinking). Note: Line Status Display LEDs for line 41 and 42 are not available.
