Note: In the case of modifying the amount of enabled BRA-ISDN port at any WW-NT\ISDN, its existing
cross-connection for B-channels transport has to be removed and a new one has to be created
according to the new condition. This could even cause other cross-connections to be re-alloca-
ted (removed-created) in order to provide for enough bearer capacity in consecutive time slots at
a certain GXDI E1 link.
Note: A 7390 platform identifies n*64 Kbits/s transport services, not presenting any link with ISDN rela-
ted resources (i.e. OWSA-channels, B channels).
•One free time slot of the selected TNT port in ISDN configuration can be cross-connected to
the signalling time-slot on the NT side.
•It is not possible to create a B-channel ISDN cross-connection if there is not created first a
signalling cross-connection.
•It is possible to cross-connect up to 8 free time-slots of the selected port and up to 8 B-
channels of the 4 ISDN-BA user port, but just 1 cross-connection by NT port. Then, it is pos-
sible to have 4 B-channel cross-connections by port.
•2 cross-connections cannot coexist over the same NT port. So, if there is a B1 cross-con-
nection and the user wants to do a B1+B2 cross-connection, he has to remove the B1
cross-connection before creating the B1+B2 cross-connection.

6.3 Preventive maintenance
Preventive maintenance is carried out by:
–permanent monitoring of the system provided by the supervision function,
–periodic inspection of the equipment to ensure that:
•the link cables between the NE elements are not damaged,
•the external equipment is properly assembled,
•the internal equipment is correctly in place.
6.4 Corrective maintenance
6.4.1 Alarms processing
Knowledge of the implicitly induced alarms may be necessary for the operator to be able to carry out
maintenance and estimate the quality of the services offered by the 7390NE. This is why the present
document offers, in this chapter, a basic knowledge to the operator of the alarm correlation.
6.4.1.1 Checking alarms for each equipment management function
The "alarms control" functions of each board's equipment management for a given type of element are
responsible for supervision, clearing and masking of alarms for this element. Each of its functions is
responsible for notification to the SNMP agent of the starts and ends of alarms that it controls.
The ANT board is in addition responsible for the processing of alarm indicators ("Critical", "Major" and
"Minor" indicators).
The AMD board implements an equipment management function for each of the following types of
element:
–the AMD itself
–the IBS
–the RBS
–the NT
–the static cross-connects on the radio link.
The TNT board implements an equipment management function for each of the following types of
element:
–the TNT itself
–the E1-G703 port of the TNT
The NT implements an equipment management function for each of the following types of element:
–the E1-G703 port of the NT
–the E1-G704 port of the NT
–the Ethernet port of the NT
After stopping the BS or resetting an ANT board (deliberately or not), DO NOT forget to
download again the same software on the available package (1 or 2) without activating nor
referencing it, to re-create the NFS assembly point so as the new NTs that come in the
network can perform automatic download.

6.4.1.2 Terminology relating to the alarms
Active alarm: an alarm is active as soon as the start of this alarm is notified to the ANT board, and
remains so as long as its end is not notified
Anomaly: discrepancy between the intended and real characteristics of an item. An anomaly may or
may not affect the capacity of this item to carry out a required function. Several successive anomalies of
the same type are generally considered a fault.
Defect: limited interruption of the capacity of an item to carry out the required function. A defect may or
may not necessitate maintenance action.
Alarm clearance: clearing an alarm initiation by notifying its end.
Board alarm function: for AMD, TNT, IBS, RBS or NT boards, the alarm function is the totality of the
"Alarms control" functions of the elements that they manage.
Alarm masking: Storage of an alarm without immediate notification of alarm initiation. Masking allows
the seriousness of the alarms for a given element to be hierarchically ordered: masking is carried out
when a higher order alarm appears. If on unmasking (carried out at the end of the higher order alarm)
the alarm which was masked is still present, an alarm initiation must be notified.
6.4.2 Definition of 7390NE alarms
6.4.2.1 Alarms relating to boards
The actions described are not necessarily controlled by the management software (they can be
controlled by the equipment itself).
In the tables below, the term "board" may related to any part of the DBS (ANT, TNT, AMD, IBS, CPL,
RBS, PSU, Fans), or to an NT.
List of the alarms relating to the boards of 7390NE:
Probable
cause Alarm name Definition Actions
Board mis-
sing Board_missing 1. One of the boards (AMD,
ANT, TNT, IBS, CPL), already
known to the agent, is physically
absent from the 7390NE.
2. When the alarm object is the
BS, it means that a load module
(i.e.: a bus adaptative board,
connected at the bottom of the
rack) is physically absent.
3.This alarm also occurs for NT
creation, when the radio link is
not established with the BS.
Internal NE actions: depends
on the functionalities and use of
this board in the 7390NE.
Operator actions:
1. Install the missing board (see
§ 6.5). If the board is inten-
tionally withdrawn, its
suppression will make the alarm
disappear (see 4.5.3)
2. Contact the TAC
(see page 3)
3. No action

ment link set-up) between the
active ANT board and the
"Board" element (redundant
ANT; TNT, AMD, IBS, CPL, coo-
ling unit, power supply unit) is
not set up or is lost.
When the alarm object is an NT,
it may mean a durable loss of
radio link.
Internal NE actions: reset
(automatic or controlled) of the
"Board" element if the board is a
TNT or AMD board or an NT.
No impact if the Board is an IBS
or RBS board: these two
elements can continue to
function without their
management link.
The setup or re-establishment of
the connection requires the
complete (re)configuration of
this element. This procedure of
(re)confguration is automatic
and internal to the BS (as long
as all the element configu-ration
parameters are valid).

6.4.2.3 Functional alarms
The 7390NE functions, for which the "Alarm" function of the ANT board manages the alarms, are as
follows:
–Time management of the 7390NE
–Synchronization of the 7390NE
–Security
–Activation of leased line cross-connects.
The table below provides the list of alarms specific to the functions of the 7390NE, along with their
definition. It also describes two types of actions:
–the automatic internal actions to the 7390NE - NR2.1, caused by the presence of each of these
alarms. The actions described are not necessarily controlled by the management software (they
may be controlled by the equipment itself).
–the actions to be done by the operator when necessary.
List of the functional alarms:
Probable cause Alarm name Definition Actions
Synchronization
clock missing Clock_missing Loss of BS internal clock used for
slaving PLL of the ANT board. Internal NE actions:
no direct immediate
impact.
Operator action: no
action.
Loss of synchro-
nization priority
clock
Priority Absence or loss of priority refe-
rence clock for 7390NE synchro-
nization.
Internal NE actions:
fallback to next priority
clock.
Operator action: no
action.
PLL unlocked Synchronization Sync roll of the ANT board PLL. Internal NE actions:
no action.
Operator action: no
action.
Round trip delay
minimization Alloc_error Impossible to allocate resources
to set up a Leased Line cross-
connec-tion, since the Round
Trip Delay minimisation require-
ment cannot be respected (and
yet the number of resources
required for setting up this cross-
connection are sufficient =>
Defragmentation).
Internal NE actions:
No resource allocated to
the "cross-connection":
rejection of the cross-
connection set-up
request by the AMD
board.
Operator action:
locking, then unlocking
all the leased lines (see
§ 4.12.1.4).

6.5 Replacing a DBS board
Note: To proceed with the extraction / insertion of a board, it is not necessary to cut the BS power sup-
ply. Do not forget to tighten the screws of the board with a screwdriver.
Note: Each time you insert or replace any board in the DBS, you must download again the same
software (click on "download" button without activing nor referencing it) This will occur the newly
inserted or replaced boards of the BS to be updated.
6.5.1 Boards other than the ANT
To change any board, other than the ANT, follow the steps below:
AFTER THE FAN MODULE IS REMOVED, BE CAREFUL WITH THE FAN BLADES.

I Extraction of the
board manifesting
a fault
For the AMD,TNT, IBS and CPL boards, the color
of their graphic representation in the BS
supervision screen changes from white to grayed-
out.
However, in the case of a module or ventilation
block, the color of the graphic representation
remains unchanged.
In the alarms list, the extracted board appears with
"Board_missing" alarm (for the AMD, TNT, IBS
and CPL boards), or "Comm_loss" alarm.
In the specific case of the AMD board, the IBS and
RBS boards associated with it give rise to a
"Comm_loss" alarm.
4.5
6.4.2.1
II Insertion of the new
board The red "F" LED on the front edge of the board
remains lit throughout the initialization and self-
configuration phase of the board, then is
extinguished.
The alarms then disappear from the alarms table.
In the specific case of the AMD board, not only do
the alarms relating to it disappear, but those of its
associated IBS and RBS boards can also appear.
In addition, the NTs attached to it are automatically
(re)integrated in the network and the E1 or IP
services become automatically accessible.

III Checking the
software version of
the re-inserted
board
In the current Alarm table, check that there is no
Version mismatch alarm for the re-inserted board;
otherwise, restart a download with neither referen-
cing nor activation (see § 7.3.12).

6.8 Malfunctions
6.8.1 Malfunctions on installation
The A7390 is a reliable and easy-to-install system. By following the procedures described in the
documentation, no problem should occur. However, if these procedures have been poorly applied, here
is a list of the possible problems that may arise.
6.8.2 In-service system malfunctions
6.8.3 Management malfunctions
Manifestation of the
problem Possible causes Solution
The equipment cannot
be powered up. Wrong 48 V polarity Restore correct polarity by following
the instructions in § 3.5.2.
Poor reception 1. Problem of polarization at RBS
2. Problem of alignment at RT
1. Check the right installation of the
antenna on the RBS (see § 3.3.5)
2. Check alignment at RT.
Manifestation of the
problem Possible causes Solution
On system start-up,
the red "F" LED
remains lit following
initialization.
1. Bad contact
2. Faulty board 1. Check that the board is properly
inserted.
2. Extract and re-insert the board
(see § 6.5). If reinserting the board
has not resolved the problem,
change the board.
With the system in
service, the "F" LED
changes to red.
Faulty board or redundant board If it is redundant AMD board, check
if there is a hardware failure on the
7390LT.
Change the board. (see § 6.5)
Loss of all NTs on the
same upstream. Bad ground connection Wire the ground connection fol-
lowing the instructions in § 3.5.2.
Sync loss on the E1
frame. The client equipment is not synchro-
nized with the NT clock. Switch equipment synchronization
from internal clock to clock signal
received from NT (see § 4.5.4).
Manifestation of the
problem Possible causes Solution
The LT session will
not run. A session is underway on the OS. Contact the OS operator to request
handover.
