ADC DNYPCS1A, DSC1902P User Manual

ADCP-75-187 • Preliminary Issue 1B • November 2005 • Section 2: DESCRIPTION

The SNMP interface is used for remote control and monitoring operations (except software
download and site number assignment). The SNMP interface uses a Management

Information Base (MIB) to define a list of identifiers that are supported by the SNMP agent.
The SNMP manager communicates with the SNMP agent over a LAN. Directives, based on the
MIB identifier, are issued by the SNMP manager to the SNMP agent along with instructions to
either get the specified identifier or set the specified identifier. The directive is then executed on
the Digivance system by the SNMP agent. The SNMP agent also has the ability to send
autonomous messages (called traps) to the SNMP manager to report changes in the status of the
managed system. The SNMP manager Stargazer Version 8.0 is available from ADC for use with
the LRCS SNMP agent. Other SNMP managers are available from various network
management software venders. Refer to the SNMP Agent Software User Manual (see Related
Publications section) for additional information.

Note 1: Per Industry Canada Section 5.3 - The rated output power of this equipment is for single
carrier operation. For situations where multiple carrier signals are present, the rating would have
to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause
interference to adjacent band users. This power reduction is to be by means of input power or
gain reduction and not by an attenuator at the output of the device.

ADCP-75-187 • Preliminary Issue 1B • November 2005 • Section 3: OPERATION

1 BEFORE STARTING OPERATION

This section provides guidelines for turning-up the Digivance system, verifying that all units are
operating properly, testing to ensure that all performance requirements are satisfied, and
correcting any installation problems. This process assumes that the various units have been
installed in accordance with the system design plan.

1.1 Tools and Materials

The following tools and materials are required in order to complete the procedures in this
section:

• Portable spectrum analyzer or RF power meter

• DC voltmeter

• External RF and optical attenuators (if specified in system design plan)

• PC-type computer with Digivance Element Management System (EMS) Version 3.01
software installed

• Straight-through RS-232 DB-9 interface cable (accessory)

•Handset

•Pencil or pen

• Writing pad

Page 3-1

ADCP-75-187 • Preliminary Issue 1B • November 2005 • Section 3: OPERATION

1.2 Readiness Check

Before starting the turn-up process, inspect the complete Digivance system to verify that all
components of the system are ready to be powered-up. This will ensure that no units of the
system will be damaged during turn-up and that all existing systems will continue to function
properly.

1.2.1 Host Unit Installation Checks

Complete the following checks at the HU prior to starting the turn-up process:

1. Verify that the ON/OFF switch on the HU is in the OFF position (press O).

Note: When connecting the equipment to the supply circuit, be sure to check equipment
nameplate ratings to avoid overloading circuits which may cause damage to over-current
protection devices and supply wiring.

2. At the fuse panel, install a 3 Amp GMT fuse in the circuit that supplies DC power to the HU.

3. Using a DC voltmeter, verify that the DC voltage level at the HU power terminals is
between ± 21 to ± 60 VDC (nominal ± 24 or ± 48 VDC). The DC power provided to the
HU can be either polarity.

4. Verify that all electrical and optical connections have been completed and that all optical
fibers, coaxial cables, and wires are properly routed and secured.

1.2.2 Remote Unit Installation Checks

Complete the following checks at the RU prior to starting the turn-up process:

1. Verify that all electrical and optical connections have been completed and that all optical
fibers, coaxial cables, and wires are properly routed and secured.

2. At the AC breaker box, make sure the circuit breaker for the circuit that supplies AC power
to the RU is in the open (off) position.

2 TURN-UP SYSTEM AND VERIFY OPERATION

The process of turning-up the system and verifying operation involves powering up the various
system components, verifying that the LED indicators show normal operation, setting the site
number and name, adjusting the RF signal levels, and adjusting the path delay.

Note: SCS systems that include a dual-band RU are comprised of two systems that operate
and function independently of each other. Each system can be independently turned-up,
tested, and placed into service. The EMS will recognize each system regardless of the
frequency/band and will display the appropriate screens. The frequency/band can be
verified by clicking on the HOST Host tab and on the REMOTE STM tab. The frequency/
band for the selected system will be displayed on the right side of the screen.

ADCP-75-187 • Preliminary Issue 1B • November 2005 • Section 3: OPERATION

Each Digivance system must be turned-up separately before being networked together with
multiple systems through the CAN interface. Use the following procedure to turn-up each
Digivance system:

1. Temporarily disconnect the external alarm system or notify the alarm system provider that
testing is in progress.

2. If the HU is networked together with multiple HU’s, temporarily disconnect the CAN cables
from the NET IN and NET OUT ports of the HU.

Note: By default, all HU’s and RU’s are programmed with the same site number and
name. This can cause problems for the EMS if multiple HU’s with the same site number
and site name are networked together through the CAN interface. It is therefore necessary
to temporarily disconnect the CAN interface cables from the HU when it is being
configured for operation until a unique site number and name can be assigned.

3. Determine if the forward path composite input signal level at the host unit RF IN port(s) is
appropriate to produce the required RF output signal level. Note that 800/900 MHz SMR
host units have two forward path RF ports. Adjust by installing an external attenuator if
necessary. For adjustment purposes, the optimum input signal level is –20 dBm for 800/
900 MHz SMR systems. Refer to Section 2.1 for the calculation and adjustment procedure.

4. At the HU: Place the ON/OFF switch on the HU in the ON position (press I).

5. At the RU: Place the AC circuit breaker switch in the closed (ON) position.

6. Wait 6 to 10 seconds for the HU and the RU to initialize and then observe the LED
indicators on the HU and RU. Refer to Section 4: Maintenance for the troubleshooting
procedures if the indicators do not respond as specified in Table 3-1.

7. Measure the input optical power level at the HU and RU and verify that the optical power
level received at the HU and RU is within –15 to –25 dBm. Refer to Section 4:
Maintenance for the optical power test procedure.

8. Connect the EMS computer (if not already connected) to the SERVICE connector on the
HU front panel. If necessary, a separate laptop computer loaded with the EMS software
can be temporarily connected and used to initially configure the system.

9. Start up the EMS software program. The EMS main window will open as shown in

Figure 3-1. The EMS software should be installed on a PC-type computer and the PC’s

COMM port should be configured to interface with the HU. For information about
installing the EMS software and configuring the PC’s COMM port, refer to the Digivance
Element Management System User Manual (see Related Publications section).

“NotNamed/NotNamed” Host/Remote pair. The HOST Alarms display and the REMOTE
Alarms display will open within the main window as shown in Figure 3-2.
