1 HOW TO USE THIS MANUAL
1.1 Introduction
1.1.1 Corrective maintenance
The network maintenance is based on the graphical supervision of the network onthe OMC–R.
It is also based on the identification and the replacement of faulty items ofequipment, using the maintenance principles described in NTP < 39 >.
This process is divided into two steps (see Figure 1–1):
locating and identifying the faulty items of equipment, using information givenin NTPs < 104 > and < 105 >
replacing the faulty items of equipment, using the replacement procedures givenin this manual (see Figure 1–2)
When a faulty item of equipment sends an alarm to the OMC–R, this alarm isidentified by a fault number. NTPs < 104 > and < 105 > give the proceduresassociated with the various fault numbers.
When a faulty item of equipment triggers several alarms, NTP < 105 > enables theoperator to locate this faulty item of equipment. It also helps the operator when anabnormal operation occurs in a BTS, a TCU, a BSC or on PCM links.
1.1.2 Preventive maintenance
The implementation of the preventive maintenance procedures is the responsibilityof each customer.
The execution of these procedures may trigger alarms at the OMC–R.
This process is divided into two steps (see Figure 1–1):
the test procedures of the items of equipment
the replacement procedures of the items of equipment
All these procedures are necessary and are described in this manual.

1.1.3 Intervention restrictions
There may be a lapse of time between the identification of the alarm at the OMC–Rand the time the operator responsible for the intervention arrives at the site.
The operator must be synchronized with the OMC–R (by telephone) before anon–site intervention, in the following cases:
isolating procedure on the OMC–R
intervention because alarms are triggered at the OMC–R
completion of an on–site intervention
return to service procedure

1.1.4.1 General safety instructions for personnel
The personnel must obey the safety instructions specific to the installation site:
rules concerning the premises (see instructions posted on site or in the building)
rules linked to the general personnel safety instructions
The personnel working on the cabinet must be authorized to work according to thesecurity standards.
The cabinet main external power supply is switched off by opening the circuitbreaker on the operator box.
The main power supply supplying the cabinet means that no work must be done onthe cabinet internal wiring without first cutting its external main power supply.
The power to the various active components of the cabinet is cut by the mains circuitbreaker. The external mains socket is no longer supplied.
This BTS has been evaluated under “IEEE C95.1 requirements, regarding safetylevels with respect to human exposure to radio frequency electromagnetic fields,3 kHz to 300 GHz”.
The leakage fields and equivalent power densities are orders of magnitude less thanthe maximum permissible exposures (MPEs) given in the IEEE safety guidelines.
1.1.4.2 Equipment safety
The operating temperature range of the e–cell is between –40°C and +50°C.
Before an intervention on the PSU, at an abnormal temperature, wait for the cooling.

6 CPM TOOL
6.1 Introduction
The transmission parameters a BTS needs to configure the communication link witha BSC, such as PCM type (E1 or T1), TEI, etc... are usually set onto electronicboards using hardware devices such as micro switches or jumpers.
This is not the case with the e–cell BTS which has been designed to restrict andtherefore to simplify the installation and maintenance processes. Here, thetransmission parameters are stored in memory and must be read at powering up tobe taken into account.
To set or change these parameters, there are two ways to proceed. The first one isto bring a portable PC on the BTS site and to program the parameters, using directlythe CPM application. The second way to set the parameters is to have a smart card,previously programmed, read by the e–cell BTS.
CPM stands for Commissioning Parameter Modification.
The equipment must be configured prior the first connection of the BTS(commissioning) and any time the radio cabinet need to be changed (maintenance).
6.2 CPM tool installation
6.2.1 PC configuration
The minimum hardware configuration is:
Pentium processor
16 Mb RAM
