are followed by the action or information required. A text string response is received from the

specified system or systems to confirm the requested action or to report the requested

information. Examples of several typical NOC-NEM interface commands and the responses

received are shown in Figure 2-18. The NOC/NEM interface requires only a VT100 terminal/

emulator or a PC-type computer that is loaded with a communication software such as

Procomm Plus. While primarily intended for use at the NOC, the NOC/NEM interface

commands may also be input from the EMS computer.

ADCP-75-159 • Issue 1 • August 2003 • Section 3: Host Unit Installation 3 HU MOUNTING PROCEDURE The HU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Both US standard and metric machine screws are included for rack mounting the HU. When loading the HU in a rack, make sure the mechanical loading of the rack is even to avoid a hazardous condition such as a severely unbalanced rack. The rack should safety support the combined weight of all the equipment it holds.

ADCP-75-159 • Issue 1 • August 2003 • Section 3: Host Unit Installation 4. Position the HU in the designated mounting space in the rack (per system design plan) and then secure the mounting brackets to the rack using the four machine screws provided (use #12-24 or M6 x 10 screws, whichever is appropriate) as shown in Figure 3-3. Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and right sides of the HU for air intake and exhaust. 17865-A Figure 3-3.

Chassis Ground Stud 5 COAXIAL CABLE CONNECTIONS The RF interface between the HU and the EBTS is supported through two N-type female connectors mounted on the HU rear panel. One connector provides the coaxial cable connection for the forward path (downlink) signal and the other connector provides the coaxial cable connection for the reverse path (uplink) signal.

WDM Installation 7 OPTICAL CONNECTIONS The optical interface between the HU and the RU is supported by two optical ports. Each optical port consists of an SC optical adapter which is mounted on the HU rear panel. Port 1 provides the optical fiber connection for the forward path (downlink) signal.

Designate one of the patch cords as the forward path link and the other as the reverse path link and attach an identification label or tag next to each connector. 3. Remove the dust caps from the HU optical ports and from the patch cord connectors that will be connected to the HU. 4. Clean each patch cord connector (follow patch cord supplier’s recommendations).

ADCP-75-159 • Issue 1 • August 2003 • Section 3: Host Unit Installation 7.2 Optical Connections With WDM System Use the following procedure to connect the optical fibers when a WDM module is installed with the HU: 1. Obtain a patch cord that is of sufficient length to reach from the WDM host module to the fiber distribution panel. 2. Remove the dust cap from the optical port on the WDM module and from the patch cord connector that will be connected to the WDM module. 3.

ADCP-75-159 • Issue 1 • August 2003 • Section 3: Host Unit Installation 8 CONTROLLER AREA NETWORK CONNECTIONS Controller Area Network (CAN) interface connections between multiple HU’s are supported by a pair of RJ-45 jacks. One of the jacks is designated as the NET IN port and the other jack is designated as the NET OUT port. The CAN interface allows up to 24 HU’s to be connected together (in daisy-chain fashion) and controlled through a single Digivance EMS computer.
