A/B Tone Generator is a part of Motorola Radio Project in KCRC West Rail Project and that is an added-on PCB to existing Motorola Equipment which can enable to inject a dual-tone multiple frequency (DTMF) pair to existing audio signal. It generates all the sixteen standard DTMF tone pairs with low distortion and high accuracy.

Hong Kong Station - North Site RCE/RCP Radio System and Mobile Radio Interface Box is a part of Motorola Radio Project in Hong Kong Station - North Site.

The TMS / HPS – NTSS Clock Interface Unit is a part of MTR Train Mobile Radio System (TMS). It is used to synchronize the real time clock between NTSS and two Message Routing Computer (MRCs)

Mode Selection Switch is a part of Kowloon-Canton Railway (KCR) West Rail project, provided by Motorola Asia Pacific Limited for KCRC. The Mode Selection Switch is composed by Mode Selection Switch Box and Mode Selection Switch. The Mode Selection Switch Box is a signal routing device. The operator can use the remote Mode Selection Switch to select the status between Team Training Mode to Cab Simulator Mode manually.

Mobile Interface Unit provides an interface access to the Mobile Radio. It converts a 600W balanced line to an unbalanced interface to Mobile Radio. It also converts Squelch logic to M signal to external equipment. In similar manner, it receives a PTT E-signal and converts to PTT dry-contact to Mobile Radio.

Tone E&M Converter plus Line Supervision Unit is to monitor and convert the audio/control signal from Digitac Comparator. The converted signal can be transferred and communicated to the remote end (MCS2000 mobile radio) through the Mobile Interface Unit.

The FRC Console Interface and Tone Generator are a part of the Expansion of MTR URL TMS/HPS Radio For TKE project. It is mainly to interface the E/M and Audio signals of 13 FRC consoles and BIM with outside equipments. The interface consists of two main parts that are Audio Path and Channel Busy Indication. The equipment has LED indicators showing the status of “E” and “M” wires.

The Radio Control Equipment and Radio Control Panel  is a part of the Hong Kong Fire Service Department radio system which are used to interface between Mass Transit Railway station communication equipment provided by Motorola Asia Pacific Limited.

 

 

 

The Basestation Keying Simulator is to facilitate the testing and maintenance of the HKP and FSD radio system. It simulates the keying tone (2175 Hz) which is generated by HKP and FSD control equipment during the communication and audio signal (1000 Hz). Also, it detects 2175 Hz and 2800 Hz tones given by the control equipment.
