Introduction:

The Micro Seven Models LS110-4 provides four simulated telephone lines. Features include programmable telephone numbers, call progress tones, simulated PBX mode, stutter dial tone, programmable disconnect signal, programmable network response delay, and distinctive ringing features. They are still specially designed to let engineers and technicians test modems and fax machines without obtaining extra in-house telephone lines

Each line may be assigned a single-digit telephone number, corresponding to its line number, or programmable telephone number. Both rotary pulse and DTMF (tone) dialing are accepted for dialing. Features include dial tone, ring-back tone, and busy tone at the calling station. Call progress tone may be available in dual-frequency type or single-frequency type which selected by dialing unique sequence of code. The ring signal is generated at the called line. A line connection is established between two stations when a call is answered. Indicators are included for POWER ON (front panel LED), and OH/BUSY for each line.

The programmable features include telephone number method, telephone numbers, call progress tones, network response delay, disconnect signals, PBX mode, and stutter dial tone.

SPECIFICATIONS

Dialing both in DTMF and rotary-pulse modes

Telephone numbers:

1. Primary telephone number: A single-digit telephone number, which is equal to a line number

of a called line. selected by dialing 043 or line1 or 2 as a factory default.

2. Secondary telephone number: selected by dialing 044.

DTMF dialing signal power: -13dBm to +5dBm per a frequency with no more than 4dB

difference between frequencies.

DTMF dialing detection time: 45 ms

Pulse dialing: Break period: 45 to 75 ms (60 ms nominal), Make period: 30 to 60 ms (40 ms

nominal)

Note: simultaneous dialing from multiple lines is availabl.’

Programming secondary telephone number: 022 (telephone number)

The factory default condition is 123456789+(line number).

Telephone number digit: 0 # 178 * n n n *, where nnn forms a 3-digit decimal number.

The default value is 10 digit. The maximum number is 18.

Simulated PBX Mode:

By dialing "9", dial tone returns when the Simulated PBX Mode was selected. Dialing "0#252*004*" for Simulated PBX Mode with dual frequency call progress tone or 0#252*012* for Simulated PBX Mode with secondary call progress tone. Note that the regular dialing methods work as well here. For example, if the secondary dialing method with a telephone number of 3456789012and the PBX mode are enabled, dialing of 3456789012 or 93456789012 would ring the other line. To return to non-PBX mode, dial 0#252*000* with dual frequency call progress tone or dial 0#252*008* with secondary call progress tone.

Line Characteristics:

Input impedance at 1 k Hz: 600 ohms +/- 5%

Signal Bandwidth:150 HZ to 5 k HZ

Battery-feed voltage (loop voltage) and loop current: -20 volts and 25 mA

Ring Signal:

30 +/- 2% Hz square wave. Normally 2 sec on 4 sec off with exception of distinctive ringing features programmed.

Distinctive ring signal features:

The following distinctive ringing pattern is enabled instead of standard 2 sec on/ 4 sec off ringing pattern:

(a). Dialing 0 * 1 + (line number): 2 sec on/ 4 sec off (default condition)

(b). Dialing 0 * 2 + (line number): 0.8 sec on, 0.4 sec off, 0.8 sec on, 4 sec off

(c). Dialing 0 * 3 + (line number): 0.4 sec on, 0.2 sec off, 0.4 sec on, 0.2 sec off, 0.8 sec on,

4 sec off

(d). Dialing 0 * 4 + (line number): 0.3 sec on, 0.2 sec off, 1 sec on, 0.2 sec off, 0.3 sec on,

4 sec off

Off-hook impedance requirement: 400 ohms maximum DC, 600 ohms nominal AC

Call Progress Tones:

1. Independently generated for each line-Dual-frequency call progress tones
Signal power: nominal -20 dBm.

Dial Tone: 350 Hz + 440 Hz, continuous unless programmed for stutter dial tone

Ring-back Tone: 440 Hz + 480 Hz, 2 sec ON/4 sec OFF.

Busy Tone: 480 Hz + 620 Hz, 0.5 sec ON/0.5 sec OFF.

Accuracy in frequency component: +/- 1%.

Caution: The dual-frequency call progress tones are not available as a standard feature in LS200 with Multi-Line DTMF Dialer Option, but they are available as an All-line Dual

Frequency Call Progress Tone Option.

2. Secondary Call Progress Tones
Frequency: 480 Hz +/- 1%

Dialing 07 enables the secondary call progress tones. Instead of generating dual

frequency call progress tones, single-frequency tone of 480 Hz is produced . Dialing 07

switches back to the dual frequency call progress tones.

Note: The secondary call progress tone is a factory-default condition.

Stutter dial tone:

Dialing 046 enables stutter dial tone with three of 0.1 seconds on/off period following with continuous dial tone. Dialing 045 disables the stutter dial tone. It is a factory default condition.

Hot line mode:

Dialing 06 sets hot-line mode. The hot-line mode for LS110 provides quick connection between lines 1 and 2 and between lines 3 and 4 without dialing. Hot-line mode is disabled when the power is recycled.

Line Input Jacks: USOC-RJ11-C, standard modular phone jacks

Power Switch

Network response delay:

Time delay between the end of dialing and ring-signal application is programmable by dialing: 0#170*nnn*, where nnn is a 3-digit decimal number between 1 and 255. The time delay is determined by 8.6 ms x (nnn-1). The number, nnn, must be non-zero. The factory default is 0 seconds.

Forced called-party disconnect:

When two lines are connected and one line hangs up, disconnect signal is generated to both lines.

Programmable disconnect signal:

The disconnect signal, which is interruption of loop current at the end of call when one line hangs up is programmable by the following dialing: 0#169*nnn*, where nnn is a 3-digit decimal number between 1 and 255. The time delay is determined by 8.6 ms x (nnn). The number, nnn, should not be zero. The factory default is 320 ms.

Power Requirements:

12VDC input @800mA, 100-130VAC input.

Fuse:

1A fast blow fuse inside LS110

Dimensions:

8.35 in (21.2 cm) Wide x 2.5 in (6.35 cm) High x 7.25 in (18.4 cm) Long.

Line Status Display: red LED for each line to indicate off-hook status (continuous on)

or ringing status (blinking)

Calibration: not required

Power On Indicator: green LED display

Weight: 2 lbs. (1 kg.)

Environmental: Operating temperature: 0 to 35 degree C, Humidity: 85% RH at 35 degree C

Warranty/Service: 6 months limited warranty. No warranty if any factory seal is broken. Service is performed at the factory, usually within 5 working days.

Programmable parameters:

Programmable parameters are restored in non-volatile memory.

Caution: The maximum number of changing programmable parameters is limited; therefore, continuous changes of programmable parameters should be avoided.

The restoration of factory default is done by dialing 04#.

The factory default conditions are as follows:

-primary (short) dialing method (single digit).

-Continuous dial tone, not stutter dial tone.

-Secondary telephone number is set for123456789+(line number), ten digits.

-No network response delay

-Disconnect signal of 320 ms

-Dual frequency call progress tones

Available options:

International AC/DC power adapter option for 90-250VAC input, 50/60Hz

Model LS110-4-1, 40V loop voltage option which provides higher loop voltage when all four lines are on-hook. Some dialers require higher loop voltage to detect on-hook condition.
