Chapter 3 Installing the TimeProvider

Getting Started

Environmental Requirements

To prevent the unit from interfering with other equipment, install and operate the unit according to the following guidelines:

Use only shielded cable for all signal wiring, including I/O, clocks and Ethernet, and ground appropriately at both ends, or as required by local standards.

Secure all cable screws to their corresponding connectors.

Caution: To avoid interference to the TimeProvider, you must consider the electromagnetic compatibility (EMC) of nearby equipment when preparing to install the TimeProvider.

Electromagnetic interference can adversely affect the operation of nearby equipment.

Gathering the Tools

These standard tools and materials are not supplied, but may be required for installing the TimeProvider:

Standard tool kit

ESD wrist strap

Cable ties, waxed string or acceptable cable clamps

No. 16 AWG (minimum) wire (1.31 mm2) for –48 V DC, return, and Frame Ground

Telecom signal wiring (including I/O, clock, and Ethernet) uses shielded cabling of the appropriate impedance required by the specific signal type

Mating connectors for terminating signal wiring

For wire-wrap connections only: No. 22 AWG (0.326 mm2) shielded twisted pair wire-wrap cable of the appropriate impedance for the specific signal requirements

Wire-wrap tool (wire-wrap modules only) Fasteners for mounting the equipment in rack

Digital Voltmeter (DVM) for verifying power connections

Soldering iron and solder for alarm connectors and the ETSI-version power connectors

DB-9 M to DB-9 F cable for connecting to the local Craft port

Laptop computer with communications software such as HyperTerminal, ProComm Plus, etc. for provisioning the TimeProvider

Optional dual-channel oscilloscope with 100 MHz minimum bandwidth for verifying input and output signals and waveforms
