T1 E1 Single or DualMultiport Repeater

Gaithersburg, Maryland, USA - Nov 13, 2019 - GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their Single or Dual Multiport Repeaters, in portable and high-density rack enclosures.

In addition to the USB based portable units, GL also offers mTOP™ rack enclosures with USB based units which can be stacked to provide a high-density form factor solution.

Multiport Repeaters are used to generate multiple identical T1/E1 outputs for each T1/E1 input, thereby increasing the range of transmission of T1/E1 signals” , said Vijay Kulkarni, CEO of GL Communications.

A single/ dual multiport repeater can be used for the following purposes:

  • To generate multiple identical T1/ E1 outputs for each T1/ E1 input
  • To test and load multiple T1/ E1 interfaces simultaneously
  • For broadcast applications and traffic generation and simulation
  • To preserve the strength of the signal and extend the transmission distance

He further added, “The single bantam version provides ten identical outputs from a single T1/ E1 input. The single RJ45 version provides 12 identical outputs from a single T1/ E1 input. The dual version provides four outputs for each of the two inputs“.

GL offers the new mTOP™ based high-density rack hardware test platforms. These are 1U/2U rack enclosures within which USB based T1/E1 Multiport Repeaters can be stacked to provide a high-density form factor solution.

Important Features of Single/Dual Multiport Repeaters:


  • The input and output connections are through standard bantam or RJ-45 jacks
  • Inputs and outputs are compatible with CCITT G.703
  • T1 and E1 signals are terminated at 100 Ohms or 120 Ohms respectively
  • The repeater permits output drive for line lengths up to 655 feet
  • The T1 Multiport Repeater and E1 Multiport Repeater are available as separate units
