    Unless otherwise stated, the TSU 610 refers to all four products. Product Description The TSU 610 is a T1/FT1 multiplexer with six option slots, an interchangable network interface, and embedded SNMP management. The TSU 610’s six option slots accept one of many available option modules for voice and data applications.

  • Page 26: Standard Features In The Tsu 610

    You can manage via SNMP through the chain-in ports. If you are using T-Watch Pro, a Microsoft Windows® program, you can manage the TSU 610 via the same chain-in ports. An enhanced VT-100 terminal interface is also provided. Standard Features in the TSU 610 The standard features of the TSU 610 are listed below: •...

    Traps are normally sent from the unit in alarm to the TSU 610. For units in the Unit Access Table that are not chained directly to the TSU 610 but are managed over Inband or the FDL, traps are not automatically forwarded. Polling must be enabled on the TSU 610 for these units in order to receive traps on the NMS.
