TELESTO is designed to connect ISDN and Ethetnet LAN telecommunication networks by means of fibre optic cables up to 120km. The device enables sending 1 to 4 ISDN (2B+D) BRI channels and connecting LAN networks in Ethernet technology for the rates of 10 or 100Mbit/s.

Brief – catalog card


Basic information

  • Connection of LAN Ethernet 10/100 Mbit/s + 4 ISDN BRI ports (2B1Q) through a fibre optical link,
  • Built-in Ethernet switch with an array of 1000 MAC addresses,
  • IEEE 802.1q support. Possibility of defining up to 15 VLAN networks (full range VID) in order to create independent transmission channels,
  • Possibility to restrict the packet rate on Ethernet ports,
  • Management: SNMP, WWW, SMTP, telnet, SNTP,
  • Local and remote software update – both firmware and GUI,
  • Built in or SFP interface: 1310, 1550, WDM, CWDM,
  • Supply voltage range 40 to 60V DC
  • Dimension 103x230x53mm or 483x170x44mm (1U) – 19” version, weight to 1,7 kg.


TELESTO is equipped with a four-port Ethernet switch. It supports features like “Flow control, VLAN, ” autocrossover “allowing to connect users without additional hardware. Each ethernet port supports programmable rate limiting from 64kbit/s to 100Mbit/s.
The available Ethernet transmission channel may be divided into fifteen independent transmission channels through the VLAN mechanism. VLAN tag/untag options, per-port basis. Embedded HTTP server, TELNET server and SNMP agent allows free configuration of the device performance by standard Web browser and continuous monitoring from any management platforms equipped with SNMP client. In addition, built-in SMTP service daemon allows to notify the operator in case of system failure. Device management is carried out out-of-band using dedicated Ethernet port.


TELESTO multiplexer is powered from DC voltage from 40 to 60 V power supply or from an external adapter supplied with the device in the case of AC voltage. Total power consumption does not exceed 10 Watts.
