MM102554V1 REV B Figure 7-5: Typical E & M Signaling Application 7.2.2 Type 1 E & M Signaling E & M Type 1 signaling uses two leads, E and M, which share a common ground path. Type 1 E & M signaling was originally designed for use with electromechanical switching systems and is not recommended for use in electronic systems due to the noise induced by the ground path. Type 1 E & M signaling keys the station remotely by using a contact closure to ground.
MM102554V1 REV B 2175 Hz SECUR-IT Tone +10 dB FUNCTION Tone 0 dB 2175 Hz Transmit HOLD Tone -20 dB 125 ms 40 ms As long as PTT switch is pressed Figure 7-6: Tone Control Sequence The “Secur-it” tone must arrive at the base station at no less than -20 dBm. The transmit “Hold” tone must arrive at the base station at no less than -50 dBm. The test tone for the voice must arrive at the base station at no less than -20 dBm.
MM102554V1 REV B If the audio is high enough to cause the telephone equipment to go into limiting, it will cause amplitude distortion. On a high loss line, the amplitude distortion will cause the “Hold” tone (2175 Hz) to vary and the transmitter to drop out. On remote systems using tone control, care must be used when connecting two telephone lines in tandem.

Before removing or replacing a module, power to the station must be switched off. WARNING 10.3.1 Procedure To prepare the module for In-Station Testing, the following steps are to be taken: 1. Remove power to the affected channel (T/R Shelf). 2. Remove the module and place the RF Module Extender Card into the T/R Shelf. 3. Insert the module into the Extender Card. 4.
MM102554V1 REV B If it is necessary to retune the modules in the field and an RF Test Fixture is not available, then use the following procedures to realign the modules. The TX and RX Synthesizers can be retuned in the field by using the metering functions available with the Utility handset SPK9024, MASTRUTL (TQ0619), or MSEDIT (TQ0653). The VCO tune voltage from the RX Synthesizer slot in the T/R shelf is connected to the external metering jack (EXT_JCK) in the System Module. 10.4.
MM102554V1 REV B 10.4.3 UHF Stations There is no requirement to align UHF Station TX Synthesizer or IF Modules. NOTE Before removing or replacing a module, power to the station must be switched off. WARNING 1. Remove the cover of the RX Synthesizer and place on an extender card. 2. Program the station for the desired TX and RX frequencies. 3. Adjust the RX Synthesizer trimmer until the LED on the front of the module goes out 4.
MM102554V1 REV B 3. Monitor J2 and align FL1 for a peak output level using a Spectrum Analyzer or RF Voltmeter. Programmable bandwidth is ±1MHz. 4. Place the Front End Module on an extender card and connect the LO out of the RX Synthesizer and the IF out of the Front End to the IF Module with 50Ω Coax cable. 5. Preset the Front End tuning slugs according to the instructions in the RX Front End technical manual and apply an “on frequency” signal into the RF In on the Front End Module. 6.
MM102554V1 REV B and battery alarm are also designed to provide the proper levels without adjustments. The LINE output level should be adjusted with a 100 mVrms, 1 kHz signal in on MIC HI or a 1 Vrms, 1 kHz signal in on VOL/SQ HI. 10.5.2 DSP Line In Level Adjustment Typically, the TX AUDIO and LINE OUT levels should be adjusted prior to adjusting the DSP LINE IN level. DSP TX AUDIO and DSP LINE/TX AUDIO are typically line audio or VOL/SQ HI audio that has been processed by the DSP Board.
