ADCP-75-150 • Preliminary Issue A • March 2003 • Section 2: DescriptionPage 2-27©2003, ADC Telecommunications, Inc.The NOC/NEM interface is acommand line interface that is presented at an NOC terminal. TheNOC/NEM interface is used for remote control and monitoring operations. The NOC/NEMinterface consists of ASCII text strings that are input as SET or GET commands which arefollowed by the action or information required. Atext string response is received from thespecified system or systems to confirm the requested action or to report the requestedinformation. Examples of several typical NOC-NEM interface commands and the responsesreceived are shown in Figure 2-19.The NOC/NEM interface requires only aVT100 terminal/emulator or aPC-type computer that is loaded with acommunication software such asProcomm Plus. While primarily intended for use at the NOC, the NOC/NEM interfacecommands may also be input from the DEMS computer.Figure 2-19.

Refer to Section 4, Subsection 2.3, before completing theforward path connection between the BTU and HU. If the Conditioning Panel or DuplexingPanel is required, refer to the Digivance 800 and 1900 MHz Interface Panels User Manual(ADCP-75-147) for the installation procedures. The HU should be mounted as close as possibleto the BTS to minimize cable losses. Use the following procedure to route and connect theforward and reverse path coaxial cables to the HU:1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxialcommunications cable (RG-400 or equivalent) for all coaxial connections.2. Route the forward and reverse path coaxial cables between the HU and the BTS interface(per system design plan) and cut to the required length. Allow sufficient slack for dressingand organizing cables at the HU and for installing an external attenuator in the forwardpath link.3. Terminate each cable with atype Nmale connector following the connector supplier’srecommendations.4. Connect the forward path cable to the FORWARD RF IN connector on the HU frontpanel as shown in Figure 3-8.Figure 3-8. Forward and Reverse Path Coaxial Cable Connections5. Connect the reverse path cable to the REVERSE RF OUT connector on the HU frontpanel (see Figure 3-8).6. Dress and secure cables at the HU.7. Complete all remaining coaxial connections as specified in the system design plan.Note: Do not connect the forward path cable at the BTS until the composite forward pathRF signal level is measured and the amount of attenuation required is determined.18655-ATYPE-N MALECONNECTORFORWARD RF INCONNECTOR(FORWARD PATH)REVERSERF OUT CONNECTOR(REVERSE PATH)
ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit InstallationPage 3-10©2003, ADC Telecommunications, Inc.7 OPTICAL CONNECTIONSThe optical interface between the HU and the RU is supported by two optical ports. Each opticalport consists of an SC optical adapter which is mounted on the HU front panel. Port 1providesthe optical fiber connection for the forward path (downlink) signal. Port 2provides the opticalfiber connection for the reverse path (uplink) signal.The optical connections are dependent on whether or not aWDM (accessory) or CWDM(accessory) module is installed. If the installation does not include aWDM, proceed to Section7.1 for the optical connections procedure. If the installation includes aWDM, proceed toSection 7.2 for the optical connections procedure. If the installation includes aCWDM, refer tothe Digivance System Coarse Wavelength Division Multiplexer User Manual (ADCP-75-142)for the optical connection procedure.7.1 Optical Connections Without WDMUse the following procedure to connect the optical fibers when aWDM is not installed with the HU:1. Obtain two patch cords that are of sufficient length to reach from the HU to the fiberdistribution panel.2. Designate one of the patch cords as the forward path link and the other as the reversepath link and attach an identification label or tag next to the connector.3. Remove the dust caps from the HU optical ports and from the patch cord connectors thatwill be connected to the HU.4. Clean each patch cord connector (follow connector supplier’s recommendations).5. Insert the connector into the appropriate optical port as shown in Figure 3-9 and asspecified by the following:Port 1 - Forward path patch cordPort 2 - Reverse path patch cord6. Route the patch cords from the HU to the fiber distribution panel.Danger: This equipment uses aClass 1Laser according to FDA/CDRH rules. Laser radiationcan seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do notlook directly into the optical transmitter of any unit or exposure to laser radiation may result.An optical power meter should be used to verify active fibers. Aprotective cap or hood MUSTbe immediately placed over any radiating transmitter or optical fiber connector to avoid thepotential of dangerous amounts of radiation exposure. This practice also prevents dirt particlesfrom entering the connector.Note: To protect the optical receivers, insert a15 dB attenuator in each optical path. Afterthe optical power has been measured, the attenuator may be resized or removed.Note: The HU optical adapters are angled to the left.Therefore, patch cords should alwaysbe routed to the HU from the left side of the rack. Routing patch cords to the HU from theright side of the rack may exceed the bend radius limitations for the optical fiber.

Clean the patch cord connector (follow connector supplier’s recommendations).4. Insert the connector into one of the WDM module’s optical ports (port 1or 4).5. Route the patch cord from the WDM to the fiber distribution panel.6. Identify the OSP cable optical fiber termination that corresponds to the RU.7. Remove the dust cap from the OSP cable optical adapter and from the patch cordconnector.8. Clean the patch cord connector (follow connector supplier’s recommendations) and thenmate the connector with the appropriate OSP cable adapter.9. Store any excess patch cord slack at the fiber distribution panel.10. Remove the dust caps from the HU optical ports and from the WDM pigtails that will beconnected to the HU.11. Clean each pigtail connector (follow connector supplier’s recommendations) and theninsert the connector into the appropriate optical port on the HU as shown in Figure 3-9 andas diagramed in Figure 3-10.Note: To protect the optical receivers, insert a15 dB attenuator in each optical path. Afterthe optical power has been measured, the attenuator may be resized or removed.Note: The HU optical adapters are angled to the left.Therefore, pigtails should always berouted to the HU from the left side of the rack. Routing pigtails to the HU from the rightside of the rack may exceed the bend radius limitations for the optical fiber.PORT 1 PORT 2HOST UNIT 1 HOST UNIT 2PORT 1 PORT 218657-AREVERSEPATHREVERSEPATHFORWARDPATHFORWARDPATHWAVELENGTH DIVISIONMULTIPLEXEROSP CABLEOPTICAL FIBERSHOST UNIT 1(BI-DIRECTIONAL FIBERLINK WITH REMOTE UNIT)HOST UNIT 2(BI-DIRECTIONAL FIBERLINK WITH REMOTE UNIT)FIBER DISTRIBUTIONPANEL (FDP)XX123 45 6
ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit InstallationPage 3-13©2003, ADC Telecommunications, Inc.8 CONTROLLER AREA NETWORK CONNECTIONSController area Network (CAN) interface connections between multiple HU’s are supported byapair of RJ-45 jacks. One of the jacks is designated as the NET IN port and the other jack isdesignated as the NET OUT port. The CAN interface allows up to 24 HU’s to be connectedtogether (in daisy-chain fashion) and controlled through asingle Digivance EMS computer. Aone meter long cable is provided with each HU for CAN connections. Use the followingprocedure to connect CAN interface cables between multiple HU’s:1. Connect one end of the CAN interface cable (provided with the HU) to either the NET INor NET OUT port on HU #1 as shown in Figure 3-11.Figure 3-11. Controller Area Network Connections2. Route the CAN interface cable to HU #2 and connect the cable’s free end to the port that isthe logical opposite of the network port the cable was connected to at HU #1.3. If athird HU will be connected to the network, connect asecond CAN interface cable tothe remaining network port on HU #2.4. Route the second CAN interface cable to HU #3 and connect the cable’s free end to theport that is the logical opposite of the port that the cable is connected to at HU #2.5. Repeat steps 3and 4for each additional HU that is added to the network up to atotal of 24HU’s. Adiagram of typical CAN interface connections is shown in Figure 3-12.Note: If connected to aNET OUT port at HU #1, connect to the NET IN port at HU #2. Ifconnected to aNET IN port at HU #1, connect to aNet OUT port at HU #2.18658-ARJ-45 CONNECTORDETAIL
