Description

Telco Systems 3100-40 ISS 2 Network Unit w/ 6690-00 PSU 2041-00 T1-CSU

A 1U rackmount T1 network interface unit designed for telecom and data network applications. Includes dual power supplies and a T1 Channel Service Unit (CSU) board for T1 line termination and management.

Specifications & What's Included

  • Model: Telco Systems 3100-40 ISS 2
  • 2x 6690-00 ISS 3 PSU (48 VDC output, 150W input, 115 VAC 60 Hz)
  • 1x 2041-00 T1-CSU board with T1, RS-232-C, and DTE interfaces
  • Connectors: DB25 (DTE, RS-232-C), Telco P2, terminal blocks
  • Status LEDs: LOS, OOF, AIS, YEL, BPV, EQPT, LPD
  • FCC Part 68 and Part 15 compliant

Applications

This unit was used in telecom infrastructures for T1 line termination, signal monitoring, and network interface management. Commonly deployed in carrier-grade network environments for multiplexing and cross-connect operations. The CSU board handled T1 protocol conversion and diagnostics for leased line connectivity.

Condition: Used
This Telco Systems 3100-40 ISS 2 Network Unit powers on and the indicators light up. We were not able to test it beyond that, so its full functionality is unknown. The unit includes two 6690-00 ISS 3 Power Supply boards and one 2041-00 T1-CSU board. Cosmetically the chassis shows normal wear consistent with rack service use. The front-panel LED indicators on the T1-CSU board and the green power LEDs on both PSU modules were observed lit during power-on. Please view our photo set and contact us if you have any questions.
