Link Precision TlOOO

Digital substation switch

The TlOOO is a fully flexible

Ethernet switch for digita

substations. It provides

highly-accurate time

synchronisation using

IEEE1588 PTP and Gigabit

Ethernet.

Sub-microsecond PTP accuracy

Gigabit Ethernet | Full Flexibility

The TlOOO switch provides all the elements needed for the IEC 61850 digital substation

network. It provides connections between lEDs that are flexible, reliable and robust,

including those that are Precision Time Protocol (PTP) aware according to the IEEE

1588 v2 standard.

A flexible, modular design allows the TlOOO to support a wide range of different

network architectures. Up to 12 interfaces can be included, each using either copper or

fibre connections. It also allows speeds of up to 1 Gbps, as required in high-end process

bus applications. The interfaces can be hot-swapped without reconfiguration.

lEDs can be time synchronised over the Ethernet network to an accuracy of less than

lus using PTP protocol. The switch can be set to operate as either a Transparent Clock

or Boundary Clock. Also the internal NTP server provides a time reference to non-PTP

aware lEDs.

Packet switching is implemented completely in hardware to ensure reliability and

accuracy. This applies even when using a mixture of different copper and fibre

interfaces.

The TlOOO can be configured and managed cyber-securely using an SSH command line

interface or an HTTPS graphical interface. The TlOOO supports RADIUS and TACACS+

remote authentication technology. Statistical management information can be accessed

using SNMP v2/v3.
