Network technology1

Network Technology

  • Nodes

    • 15 stand-alone buildings (11.6’x26’)

      • 8 Core Nodes (Reno, Carson City, Lee Vining, Mammoth, Bishop, Lone Pine, Ridgecrest, Barstow.

      • 3 Regeneration Sites (Coleville, Kramer Junction, Olancha)

      • 4 Tributary Nodes (Bridgeport, Benton, Big Pine, and Independence)

    • Reno and Barstow Nodes are interconnection points into the PSTN and IP Peering.

    • Note: Reno and Barstow nodes may be 11.5’x40’

For Discussion Purposes Only


Initial customers sites per node

For Discussion Purposes Only


Considerations power

Considerations: Power

  • What is your bank-power scheme? These questions are asked because the power system design for the node is not complete and can't be until the electronic equipment is selected.

  • How many feeders are required per bank? Some vendors use 4, others only 2. The answer could have significant impact on our power design.

  • What is the termination type of the power feeder on the bank? Lug? Connector? Details are needed.

  • Our practice is to fuse the feeders at the distribution fuse board. Secondary fuses (at the equipment will not be used. Does the equipment use any additional fuses such as found on some circuit packs. If so, please provide details.

  • Are any circuit packs or blades on your system configured as n+1? Hot swappable? (Need to be accounted for in the power load calculations.) Assuming normal operating voltage is -48 vDC, what is your low limit? High limit?

For Discussion Purposes Only


Considerations heat

Considerations: Heat

  • What is your NEBS load for a (fully equipped) 7 foot frame. The reason for this question is often, significant bay space must be left unoccupied for very high heat dissipation. I am asking only of the heat issues not mechanicals.

  • What are your high and low operating temperatures?

  • If your equipment is hardened (over 50C) How hard? 65C?

  • Are there any sub-systems used that are not hardened? I ask this because I have seen systems that were hardened to 65C that used certain circuit packs that were “stuck at 50”.

For Discussion Purposes Only


Considerations racking and support

Considerations: Racking and Support

  • Can you demonstrate your jumper management scheme for a frame configured to the maximum capacity? The reason for the question is the building jumper management will use ADC Fiber Guide to keep the pile manageable.

  • Is the inner-frame routing compatible with ADC's system?

  • Will we be providing any services using CAT-5 or CAT-6 cabling? If so, then some CAT-6 interbay cabling will be required.

  • Will we need to be concerned with routing and racking supports for CAT-5 or CAT-6 cabling? What is your footprint? We need to fit within the frame lineup and not intrude on power space.

  • Are your banks configured for 19 inch racking? If so, are your 23 inch adapters compatible with ADC's fiber management system?
