GENERAL Exercise extreme care when handling any electronics equipment as it contains precision parts that can be damaged by improper handling. Avoid touching connector pin surfaces. Foreign matter deposited on contact surfaces can cause corrosion, and eventually lead to degradation of performance. In addition, do not use abrasives to clean contact/pin surfaces. ESD CONSIDERATION Each module contains semiconductor devices that can be damaged by electrostatic discharges. It is advisable to take anti-static precautions when handling electronic boards or static sensitive components. Use an approved anti-static bracelet in accordance with company practice. WATER AND MOISTURE Do not place containers with liquids such as coffee, water, sodas, etc. on the unit. Do not operate this equipment in a wet environment. HEATING Do not install this product near heat sources such as radiators, air ducts, areas subject to direct, intense sunlight, or other products that produce heat. VENTILATION To protect the unit from overheating, when integrating this unit in a rack cabinet, at least 1 RU (4.3 cm) of clearance above and below the unit is necessary to assure sufficient cooling. GROUNDING EARTH CONNECTION IS ESSENTIAL BEFORE CONNECTING TO THE SUPPLY. Ensure that all devices connected to the unit are connected to its protective (earth) ground. Any interruption of the protective grounding or disconnecting the protective earth terminal is likely to make the equipment dangerous. Intentional interruption is prohibited. POWER Make sure the power sources are compatible with the power inputs of the equipment. Verify that the correct fuses are installed. The equipment's protective earth terminals must be connected to the protective conductor of the station earth. The mains AC plug shall only be inserted in a socket outlet provided with a protective earth contact. The protective action must not be negated by the use of an extension cord (power cable) without a protective conductor (grounding). POWER CORD PROTECTION The supplied power cables connected to the unit should be routed or installed in such a manner to protect it from being walked on or pinched. The unit should be powered down completely before connecting or disconnecting the power cable. The power cord should be removed before moving the unit. The power cord must be placed near an easily accessible unobstructed socket outlet. AceCom Networks Pte Ltd. 3

CLEANING Connected and running equipment can only be dusted using a soft dry cloth. ONLY WITH, AUTHORIZED PERMISSION, OUT OF SERVICE & UNPLUGGED equipment can be cleaned with a soft cloth slightly moistened with a mild detergent solution. Do not use liquid cleaners, aerosols, abrasive pads, scouring powders or solvents, such as alcohol. Ensure the cleaned surface is fully dry before reconnecting power. SERVICING AND MODIFICATIONS To avoid dangerous electric shock, do not perform any servicing or modifications, other than recommended, in this User Manual. Do not attempt to gain access to areas of the unit where dangerous voltages are present. Refer servicing to qualified service personnel. DAMAGE REQUIRING SERVICE Refer servicing to qualified service personnel under the following conditions: When the power supply cord is damaged. If liquid has been spilled on the enclosure of the unit. If the product does not function normally by following the instructions in the User s Manual. Adjust only those controls that are covered by the operating instructions. Improper adjustment of other controls may result in damage and will often require rework by a qualified technician to restore the product to its normal operation. If the product has been damaged in any way. When the unit displays a negative, distinct change in performance. AceCom Networks Pte Ltd. 4

Section 1: System Description and Installation Product Overview VCL-GPS-2145, Primary Reference Clock and IEEE-1588 Grandmaster with NTP Server is a high precision, multiservice, cost efficient time and frequency synchronization solution which can be used to provide ITU-T, G.811 reference frequencies which are referenced to a GPS source, as well as to synchronize the time-of-day and frequency across multiple nodes of the network. The VCL-GPS Receiver has an integrated, high bandwidth NTP Server engine that is capable of handling up to 5500 NTP requests per second. Multiple IRIG-B Outputs are also provided to synchronize local clock (time-of-day) display units as well as RTUs to a central timing source with nanosecond accuracy. The VCL-GPS-2145, Primary Reference (PRC) Clock is specifically designed for the synchronization of 2G, 3G, HetNet and LTE mobile telecommunications networks as well as backhaul wire-line SDH / SONET and Synchronous Ethernet networks. It may be also used by Railways, Airports (including air-traffic control), Power generation and distribution companies and other Utility companies who not only require a highly precise time-of-day and G.811 frequency synchronization locked to a GPS Reference but who also need to distribute highly precise time-of-day and frequency synchronization across all nodes of their networks. The VCL-GPS-2145 is always locked to a GPS reference to provide multiple G.811 / Stratum 1 quality frequency and time-of-day (IRIG-B and NTP) outputs. The VCL-GPS-2145 is also equipped highly accurate, low-noise OCXO / Rubidium oscillator which provides a high stability holdover clock that is typical of a Network SSU in the event of the GPS signal or its antenna failure.

Management Interfaces and Software: The VCL-GPS-2145, GPS Receiver can be managed by any Windows based PC connected to the equipment via a serial RS-232 or a USB connection, or over a 10/100BaseT Ethernet / IP link using Telnet communication protocol. A user friendly GUI is also provided that gives the user the ease for configuration and management. It provides an easy-to-use interface for configuring the unit and displaying its current status such as the visible GPS satellites, the unit s operational state, the status of the outputs and power supplies etc. The equipment may be monitored by the network administrator from a central location using SNMP. An NMS (Network Management Software), capable of monitoring up to 500 nodes over an IP network is provided free-ofcharge along with the equipment. An MIB file is also provided for integration with third-party NMS. The unit also provides an alarm relay contact for connecting an external audio or visual alarm.
