UniSync

Further product information.

It has been designed to comply with all ETSI, Telcordia and ITU-T G.811 and G.812 international telecom recommendations. It is based on a high performance GPS timing receiver and it can be equipped with additional reference input modules to accept two timing reference signals of various formats and sources. To ensure a high precision of synchronization signal on the outputs even in case of GPS reception failure, UniSync is equipped with an internal oscillator. User can choose from OCXO, DOCXO or Rubidium.

UniSync is controlled via a GUI installed on a PC, the connection can be made by means of console port or RJ-45 management port based on IP address.

Inputs

The UniSynce can be equipped with 2 bridged input ports. This requires one plug-in module per input. Each external input port is independently software configurable for standard signal frequencies as follows:

• DS-1 1544 kbit/s, Framing selectable -- SF or ESF
• E-1 or 2048 kHz
• Optional 1/5/10 MHz

Each input is monitored for LOS, AIS, OOF, and BPV when apply. SSM messages are also monitored when available.

Outputs

• Two output ports are available in the base configuration - software assignable 2048 kHz, E1.
• One additional plunging module provides 10 more output ports - software assignable 2048 kHz, E1.
• UNISync has also 2 users selectable analog frequency outputs via BNC for 1, 5, 10 MHz and 1 PPS via BNC.

 

Frequency Feedback Module

Moreover, a Frequency Feedback Module is available providing 10 Outputs and 10 Feedback Monitoring interfaces for continuous NE (Network Element) frequency monitoring. Typically these inputs are driven by synchronized network elements, so they should have the same frequency as the UNISYNCe local oscillator. The aim is to alarm the management center in case of significant frequency error. This frequency error likely indicates a malfunction of the
connected network elements (synchronization reference loss).

NTP/SNTP:

The equipment can also used for computer time synchronization, thank to its NTP / SNTP server stratum level 1

In cases where larger-scale synchronization supply solution is needed, UniSync is ready to be integrated into a proprietary centrally managed system LYNX, capable of remote controlling virtually unlimited number of SSUs with the ability to access individual supply units for modifications as well as to constantly monitor the health and performance of the whole network. Using the preconfigured alarms, each undesirable condition, clock quality deterioration or failure can be immediately recognized and mitigated.
