JMC (known as Pepe) is ALBEDO GM. He is expert in Telecom and Power Utility protocols. He has been teacher at the UPC university and author of several books about SONET/SDH and Triple Play and has published a number of papers about the instalatio and maintenance of IEC-61850 in Power Utilties.
Net.Time φ is a clock equipped with 2 x Gb/s port that is able to manage 512 PTP unicast clients, 22 outputs and 9 time references. Rubidium / OCXO are optional and it supports PRP, PTP, NTP, ToD, n x PPS, IRIG-B, DCF77, MHz, T1, E1.
Net.Time φ is a Master PTP/NTP designed to facilitate a seamless integration of legacy infrastructures with IEC 61850 deployments. It is equipped with 2 x optical (SFP) and 2 x electrical (RJ45) interfaces from 10Mb/s up to 1Gb/s supporting PTP, NTP, SyncE, ToD, IRIG-B, DCF77, T1, E1 and BITS. The internal oscillator can be Rubidium or OCXO to be disciplined with any signal including GPS, PTP, PPS, MHz, TDM, SyncE and IRIG-B as well.
Fig 1. Time flexibility, scalable and modular.
Flexibility: options include PTP, NTP, ToD, Time Pulses, IRIG-B, DCF77, MHz, SyncE and E1/T1. It can also simultaneously manage clients with different PTP profiles.
Protocol Translator: PTP, NTP, ToD, IRIG-B are accepted as input time references while clock output for time distribution can be PTP, NTP, ToD, Time Pulses, IRIG-B, DCF77, MHz, SyncE and E1/T1.
Interconnections: Net.Time offers seamless translation of protocols by means of a wide variety of inputs / outputs for primary or backup time references..
Native PRP: The PRP offered by Net.Time, for both NTP and PTP, deserves to be highlighted as it avoids the use of external RedBoxes that would increase the cost of the installation.
PTP Migration: : Net.Time ensures PTP co-existence with SNTP, IRIG-B that favors cooperation, interconnection and smooth migration as all time protocols are treated with the same level of accuracy.
512 clients : It has 2 x Gigabit ports and a hardware PTP engine capable to synchronize 512 clients in unicast mode
Fan-less Operation: Net.Time is a clock totally prepared for the challenging environment and temperature up to 65ºC of substations
PTP Roles: The clock can be configured as stand-alone GPS clock, Grandmaster or slave clock.
Redundancy: Single or Double power supply is accepted in a redundant configuration options.
Fault Tolerant: Net.Time accepts several references that can be programmed hierarchically making it in a sophisticated, versatile and reliable clock.
Net.Time has awesome features to meet the state-of-the-art synchronization based on IEC standards while maintaining the installed base.
Fig 2. Power Substation.
This appliance was conceived to pave the transition to smart substations. With this purpose in mind Net.Time offers seamless translation of protocols by means of a wide variety of inputs / outputs for primary or backup time references.
Smooth migration to PTP
Net.Time ensures that the new and more accurate PTP will be able to co-exist not only with SNTP but also with the veteran and robust IRIG-B. This coexistence will likely last for years and for this reason Net.Time integrates these –and many more time protocols– under a powerful and dedicated architecture that favors cooperation, interconnection and eventually smooth migration. All technologies will continue to function normally and harmoniously thanks to the versatility provided by advanced electronic design in addition to the powerful processing capabilities of FPGAs. Therefore, all protocols are treated with the same respect to deliver the best possible level of performance and accuracy.

Fault tolerant to reference
GPS is the most common reference, but we know that it is vulnerable then Net.Time accepts several references that can be programmed hierarchically making it in a sophisticated, versatile and reliable clock.
