Weehawken Tunnel 900MHz Pager System User/Maintenance Handbook Handbook Nō.-Weehawken_900 Issue No:-A Date:-05/08/05 Page:- 12 of 50 2. OVERVIEW/ SYSTEM DESCRIPTION 2.1 General System Description The Weehawken tunnel radio system is designed to amplify various bands of radio frequencies, in either channelised or band selective modes. All the hardware is built into standard 19” rack mounted cabinets which have an environmental IP rating of 54. There is also a single, free standing wall mounted amplifier which carries the whole signal network to the River Portal area. The system in this document will be described separately, as individual shelves (900MHz Pager) and the various passive combiners, splitters and cross-band coupler shelves will also be described in separate documents. Every active module in the entire system has a dedicated alarm and these are series wired within the shelves to a relay which gives a volt-free output pair for each shelf which is wired to a ‘krone-block’ termination in the rack cabinet.

DOWNLINK PAGING AMPLIFIER 4.1 Two Channel 900MHz Pager Cell Enhancer (50-118501) 4.1.1 Two Channel 900MHz Pager Cell Enhancer Description The pager cell enhancer provides two channels (downlink only) in the 900MHz band for the NJ Transit system. These two frequencies are relayed to all the sites (leaky feeders) in the system. All amplifiers have built-in alarms which are configured as a summary, volt-free relay contact pair terminating at pins 1 & 2 on the ‘D’ type alarm connector. 4.1.2 Two Channel 900MHz Pager Cell Enhancer Technical Specification PARAMETER SPECIFICATION 929.5875MHz (Downlink) Frequencies: 929.6125MHz (Downlink) Gain: >90dB Gain Adjustment: 0 - 30dB (in 2dB steps) Shelf size: 4U Uplink Power: >1.0Watts Maximum uplink output: +30.8dBm Downlink Power: >5.0Watts Maximum downlink output power: +37.5dBm Uplink +44dBm IP3: Downlink +50dBm Downlink Ch. module AGC level: -17dBm Uplink Ch. module AGC level: -8dBm Noise Figure: <6dB (at maximum gain) AGC: Fitted in channel modules VSWR: better than 1.5:1 RF Connectors: N type, female operational: -10°C to +55°C Temperature range: storage: -40°C to +70°C Case: Alocrom 1200 Heatsinks: Matt black Handles: Silver anodised alloy Finish: Fascia: Painted to RAL 7035 1 Downlink amplifiers 2 Uplink amplifiers Alarms Fitted: (volt-free contacts/TTL) 3 Each channel module Weehawken Tunnel 900MHz Pager System User/Maintenance Handbook Handbook Nō.-Weehawken_900 Issue No:-A Date:-05/08/05 Page:- 22 of 50 5. POWER SUPPLIES & ALARMS 5.1 800MHz Power Supply (80-231302) 5.1.1 800MHz Power Supply Description The power supply for the 800MHz cell enhancer uses 15V PSU modules ‘turned down’ to 12V (all the amplifiers in the 800MHz CE use 12V DC supply). It is a standard power supply shelf using two PSU modules with their outputs combined through power diodes and terminating in six, dedicated 12V outputs. Failure of either PSU module will trigger a non- latching summary alarm, (short-term mains failures will allow the system to return to a ‘non- alarmed’ state). The alarm interface is on the alarm ‘D’ connector pins 1 & 2. 5.1.2 800MHz Power Supply Technical Specification PARAMETER SPECIFICATION Input: 110V AC @50/60Hz (single port) Outputs: 6 x 12V DC @ 20A each Front panel indicators: (x 2) Green LED for ‘PSU1/PSU2 ON’’ Fuses 1 x 20A each outlet socket DC Socket XLR operational: -10°C to +55°C Temperature range storage: -40ºC to +70ºC Alarmed devices: Either PSU failure Alarm interface (volt-free contacts): ‘D’ type alarm connector, pins 1 & 2 MTBF: >50,000 hours Earthing: M8 stud 5.1.3 800MHz Power Supply System Diagram The system diagram is not available at the time of writing this document. Weehawken Tunnel 900MHz Pager System User/Maintenance Handbook Handbook Nō.-Weehawken_900 Issue No:-A Date:-05/08/05 Page:- 25 of 50 5.2 Alarm/Monitor Shelf (80-231303) 5.2.1 Alarm/Monitor Shelf Description The alarm shelf acts as an alarm concentrator for all the alarms in the system. Firstly, within each shelf containing active components, the individually alarmed modules are ‘summed’ and presented to that shelves’ 9-way alarm connector as a volt-free relay contact pair. These alarm contact pairs are wired to the krone block in the lower rack space and from there the pairs are presented to the alarm shelf. At the alarm shelf the pairs are summed together to form an overall system alarm. In this way a system alarm may be broken down to scrutinise the shelf alarm and ultimately to the individual modules’ alarms. This shelf has its own dedicated mains-driven power 12V DC supply. As all the alarms in the system are ‘held closed loops’, should any power supply fail, the main system alarm will be triggered. 5.2.2 Alarm/Monitor Shelf Technical Specification PARAMETER SPECIFICATION Operating voltage: 12V (floating earth) Alarm output relay contacts: Max. switch current: 1.0Amp Max. switch volts: 120Vdc/60VA Max. switch power: 24W/60VA Min. switch load: 10.0μA/10.0mV Relay isolation: 1.5kV Mechanical life: >2x10 7 operations Relay approval: BT type 56 Connector details: 25 Way ‘D’ Connector operational: :-10°C to +55°C Temperature range storage: :-40°C to +70°C Weehawken Tunnel 900MHz Pager System User/Maintenance Handbook Handbook Nō.-Weehawken_900 Issue No:-A Date:-05/08/05 Page:- 27 of 50 6.
