3.0 SERVICE LEVELS
3.1 NNSS TECHNICAL SUPPORT RESPONSE
The corrective course of action to be taken by Nortel Networks shall be
determined by the Case Severity Classifications, as defined below.
3.1.1 CASE SEVERITY CLASSIFICATION
Nortel Networks shall measure the severity of Hardware or Software incidents
according to the following TL9000 Customer Severity definitions for Critical,
Major, and Minor Hardware/Software problem reports. If it is not clear which
severity level applies, then the severity level assigned by Nortel Networks'
customer (the Service Provider) shall be used. However, if a problem clearly
belongs to a given severity level as defined below, then that severity level
shall be used.
Nortel Networks uses case priorities that correspond to the TL9000 Customer
Severities as shown in the following table:
TL9000 Nortel Networks
Customer Severity Case Priority
----------------- -----------------
Critical E1
Major E2
Business Critical
Major
Minor Minor
3.1.1.1 CRITICAL NORTEL NETWORKS CASE PRIORITY= E 1
In accordance with TL9000 Customer Severity, a Critical problem is a problem
that severely affects service, capacity/traffic, billing, and maintenance
capabilities. Critical problems require immediate corrective action, regardless
of time of day or day of the week.
Nortel Networks prioritizes Critical problems as E1. Following service
restoration, a sub-case may be opened to conduct further root-cause analysis.
Examples of Critical problems include:
o A loss of service that is comparable to the total loss of effective
functional capability of an entire switching or transport system.
XXXXXX AND NORTEL NETWORKS CONFIDENTIAL AND PROPRIETARY INFORMATION PAGE 9
Support Services Statement of Work
o A reduction in capacity or traffic handling capability such that
expected loads cannot be handled.
o Any loss of safety or emergency capability (for example, emergency
calls such as 911 in North America).
o Loss of the system's ability to perform automatic system
reconfiguration.
o Inability to restart a processor or the system.
o Loss of protection switching capability.
o Loss of billing capability.
o Corruption of billing or system databases that requires
service-affecting corrective actions.
o Loss of access for maintenance or recovery operations.
o Loss of the system's ability to provide any required system
critical/major alarms.
o Other problems that severely affect service, capacity/traffic, billing,
and maintenance capabilities or are viewed as critical jointly by
Nortel Networks and the Service Provider.
3.1.1.2 MAJOR SEVERITY NORTEL NETWORKS CASE PRIORITIES= E2, BUSINESS CRITICAL,
MAJOR
In accordance with TL9000 Customer Severity, Major problems are problems that
cause conditions that seriously affect system operation, maintenance, and
administration. Major problems require immediate attention. The urgency is less
than a Critical problem because of a less immediate or impending effect on
system performance, end-users, operation, and revenue.
Nortel Networks prioritizes Major problems as E2, Business Critical, and
examples include:
o Reduction in any capacity/traffic measurement function.
o Any loss of functional visibility and/or diagnostic capability.
o Short outages equivalent to system or subsystem outages, with
accumulated duration of greater than two minutes in any 24-hour period,
or that continue to repeat during longer periods.
o Repeated degradation of DS 1/E1 or higher rate spans or connections.
o Prevention of access for routine administrative activity.
o Degradation of access for maintenance or recovery operations.
o Degradation of the system's ability to provide any required system
critical/major alarms.
o Any significant increase in Product-related customer trouble reports.
o Billing error rates that exceed specifications.
o Corruption of system or billing databases.
o Other problems that disrupt or prevent routine system activities, or
are viewed as major jointly by Nortel Networks and the Service
Provider.
XXXXXX AND NORTEL NETWORKS CONFIDENTIAL AND PROPRIETARY INFORMATION PAGE 10
Support Services Statement of Work
To provide increased focus on certain types of Major problems, Nortel Networks
uses the following case priority definitions:
o E2 (loss of redundancy): Potential service degradation and/or total
outage. Serious situation not involving service degradation in a live
environment, but leading to a total or partial loss of redundancy.
Following service restoration, a sub-case may be opened to conduct
further root-cause analysis.
o BUSINESS CRITICAL (service and performance affecting): Any major
degradation of system or service performance that impacts customer
service quality or significantly impairs network operator control or
operational effectiveness. Overall network is degraded, resulting in
severe limitations to the Service Provider's operations, or network
management Software Product has a major feature that is dysfunctional
with only a difficult work-around.
o MAJOR PROBLEM (service and performance affecting): Any major
degradation of system or service performance that impacts customer
service quality or significantly impairs network operator control or
operational effectiveness. This includes situations in which a network
component is down, there is a network problem, there is a functional
loss resulting in partial limitations to operations, or network
management Software Product has a major feature, which is
dysfunctional, but has a simple work-around.
3.1.1.3 MINOR NORTEL NETWORKS CASE PRIORITY
In accordance with TL9000 Customer Severity, Minor problems are problems that a
Service Provider does not view as Critical or Major. Minor problems neither
significantly impair the functioning of the system nor significantly affect
service to end-users. These problems are tolerable during system use.
3.1.2 TECHNICAL SUPPORT INCIDENT CLASSIFICATIONS AND CORRESPONDING ACTIONS
The classification and case priority for Technical Support shall dictate the
action and responsibilities of both Nortel Networks and Nortel Networks'
customer (the Service Provider). Each problem report shall be classified and
resolved as set forth in the table below:

1.1 OBJECTIVE
The objective of this document is to provide equipment
requirements for antenna sharing between GSM and TDMA base
stations. Current solutions are proposed herein for base stations
containing solely Nortel Networks TDMA and GSM products located in
different cases of co-location.
1.2 Introduction
There are currently a number of operational TDMA networks over
which operators plan to deploy GSM. To protect their TDMA
infrastructure investment, the operators would like to reuse the
existing TDMA equipment as part of the deployment of the new GSM
equipment. However, not only does this require that the equipment
be reused, but also the equipment must be used simultaneously by
both technologies. In particular operators are interested in
reusing the already deployed antennas and coax cable feeding those
antennas. The specifications and network equipment changes
discussed herein give ways through which such antenna sharing may
be achievable.
1.3 RF CONDITIONS OF THE CO-LOCATION
TDMA and GSM systems may coexist and operate with the existing
TDMA antennas and coaxial cables, provided that a number of
conditions are met. These conditions are specific to the
characteristics of the existing antennas and coax. Some of the
most basic conditions that must be met are:
o A minimum of two antennas are available per sector
o Combined composite power of both systems does not exceed
the engineered antenna maximum power requirements.
o Adequate isolation can be achieved which includes enough
antenna spacing to avoid interference between different
technologies, when applicable.
o Sufficient spectrum must be available to support channel
separation of the TDMA and GSM frequencies, including guard
bands.
o Special frequency filters and/or diplexers may have to be
employed to filter the appropriate channels for each
system, which may impact link budgets.
o Antenna frequency response capability must be broad range
enough to support both bands.
2
o Configurations such as S332 with Duplexer and TX Filters
are not supported with either 3 antenna or 2
antenna-sharing solutions.
o Microwave transmission equipment intergraded in the outdoor
GSM BTS cannot be supported with either 3 antenna or 2
antenna-sharing solutions.
1.3.1 BTS EQUIPMENT AND CONFIGURATIONS

1.3.2 THREE ANTENNAS AND COAXIAL CABLE EQUIPMENT SHARING (INDOOR)
CONFIGURATION
[GRAPHIC -INDOOR THREE ANTENNAS SYSTEM SHARING CONFIGURATION]
DETAIL CONNECTION
TDMA Tx antenna remains unchanged. Both TDMA Rx antennas will be
sharing with the GSM system. The TDMA Rx signal will receive from
the GSM duplexer/LNA/Splitter, an external attenuator, and then go
into the TDMA ERMC.
The GSM could use one or two antenna(s) to transmit the signal,
and uses both sharing antennas to receive the signal. H2D may be
required for this configuration depends on the number of the
carriers deployed in the GSM cell.
3
The setting for the external attenuators may need to be adjusted
based on the field measurement.
[GRAPHIC-DETAIL DIAGRAM FOR INDOOR THREE ANTENNAS SYSTEM SHARING]
PART LIST
The following is the list of parts that are required for sharing:
o 1 Bulkhead adapter kit with bulkhead plate for GSM BTS
- Includes 2 internal Rx cables
o 2 Manual-step attenuators (N-female to N-female)
- Frequency range: 0 to 25 GHz
- Attenuation: 0 to 30 dB
- Part Number: 50DR-055 N (Manufacturer: JFW Industries)
o 2 LMR-200 cables (N-male to N-male)

- Part number: 910-2223 (Manufacturer: Antrum)
NOISE FIGURE (NF) AND RX SIGNAL GAIN
There will be a minimum impact on GSM NF and Rx signal gain
because GSM Rx connectivity remains the same between sharing and
non-sharing.
Study shows that TDMA NF and Rx signal gain is affected by the
sharing and that the insertion of an attenuator could minimize the
impact.
The following table shows the TDMA stand alone NF and RX Gain.

Impact to System N F 0.00
Impact to System Gain 3.23
With insertion of a 19.2dB attenuator (include cable and pad to
the ERMC) on the sharing configuration, one can conclude that the
impact on the NF may be minimally changed by comparing the Sys NF
on the Antenna Jumper (both tables show 7.85dB); one can also
conclude that there will be 3.23dB gain on the Rx path by
comparing the gain from antenna jumper to eRMC (4.88dB vs 1.65dB).
With a 3.23dB gain on the Rx signal, an up link RF parameter
adjustment is needed to maintain existing TDMA system performance.
The HOTL value needs to be set 3 dB stronger for the non-MAHO
prescreening. For instance, if the HOTL was set to -80dB prior to
the sharing, the HOTL needs to be set to - 77dB after the sharing.
Another option that can accommodate the 3.23dB Rx gain is to set
the RSSI offset value in the TDMA radios.
Also, one can increase the step attenuator inside of the ERMC to
offset the gain.
5
TX POWER
Both GSM and TDMA Tx power are not affected by the sharing since
the path for the Tx antenna for both systems are the same as the
stand alone one.
IM (CASCADED LNAS)
IM will not degrade with the sharing due to:
o Input IP3 may change; however, due to current product has a
high margin on IP3 point, the change is still within the
limit of the IS 136 compliancy.
o With an added attenuator between LNAs to compensate the
first LNA gain, the second LNA should not be overdriven.
NOISE FLOOR
Since the GSM Rx path remains the same, the GSM noise floor will
remain unchanged for the sharing.
TDMA Noise floor is changed 3dB with the antenna sharing. In the
event the NSTHRESH is set to an absolute value, the value will
need to be adjusted to eliminate the noise floor impact. For
instance, if the NSTHRESH was set to - 100dB before the sharing,
the NSTHRESH should be set to -97dB after the sharing. The signal
to noise ratio (S/N) is not affected by the sharing since the RSSI
of the signal also changes. The amount of the change between
noises and signal are the same.
RF COVERAGE
There will not be any RF coverage impact on the GSM system.
There is less than 1 dB degradation on TDMA sensitivity due to the
change of linearity, IM, and interference; but the receive
sensitivity is still in compliance with IS 136.TDMA Tx power is
not changed for this configuration.
1.3.3 TWO ANTENNAS AND COAXIAL CABLE EQUIPMENT SHARING (INDOOR) CONFIGURATION
[GRAPHIC-INDOOR TWO ANTENNAS SYSTEM SHARING CONFIGURATION]
DETAIL CONNECTION
One antenna is directly connected to the TDMA system to transmit
and receive TDMA signal. This antenna is also to act as the GSM
diversity antenna to receive the GSM signal. The GSM diversity
signal goes through TDMA ERMC, an external attenuator, GSM
duplexer/LNA/Splitter, and an internal 4dB fixed Pad.

The other antenna is directly connected to the GSM system to
transmit and receive the GSM signal. This antenna is also to act
as the TDMA diversity antenna to receive the TDMA signal. The TDMA
diversity signal goes through the GSM duplexer/ LNA/Splitter, an
external attenuator, and the TDMA ERMC.
The setting for the external and internal attenuators may need to
be adjusted based on the field measurement.

NOISE FIGURE (NF) AND RX SIGNAL GAIN
With the GSM diversity receiver going through the TDMA system, the
impact for GSM NF and Rx signal gain can be reduced to a minimum
by inserting a pad before the Rx signal goes into the GSM
duplexer, and another 4dB fixed pad after the GSM duplexer.
The following table shows the GSM stand alone NF and RX Gain.

One can tell that the impact on system NF is about 0.7dB by
comparing the Sys NF from Antenna Jumper (6.1dB for the sharing
and 5.4 dB for the stand alone one). The difference on gain for
the diversity Rx path is only 1.27dB by comparing the gain from
Antenna Jumper to DRX on both tables (26.81 dB vs. 25.54dB).
With the TDMA diversity Rx signal going through the GSM system,
the TDMA NF and Rx signal gain is also affected by the sharing,
however, the insertion of an attenuator in front of the TDMA ERMC
could minimize the impact and its use may be necessary.
The following table shows the TDMA stand alone NF and RX Gain.

GSM Noise floor may be impacted at the minimum (1.27dB).
TDMA Noise floor is changed 3dB with the antenna sharing. In the

There will not be any RF coverage impact on GSM and TDMA forward
path.
There are about 0.5dB degradation on GSM sensitivity, and less
than 1dB degradation on TDMA sensitivity due to the change of
linearity, IM, and interference; but the receive sensitivity is
still in compliance with GSM05.05 and IS 136.

1.3.4 TWO ANTENNAS AND COAXIAL CABLE EQUIPMENT SHARING (OUTDOOR)
Two options are presented in this document for outdoor two
antennas sharing.
Option 1, both antennas are directly connected to the GSM system.
This option requires an extra external duplexer before the signal
going to the TDMA BTS to overcome the TDMA frame limitation (only
two RF path can go through the frame). The limitation on this
option is that TDMA can only support up to 14 carriers/sectors
with average power of 7W/carrier (based on the link budget). Less
TDMA radio can be supported with peak power for this
configuration. Also, this option requires extra ERP power to
offset the TDMA Tx power loss on the duplexers.
Option 2, one antenna is directly connected to the TDMA system;
the other one is directly connected to the GSM system. This option
requires the knock out of one of the six pre-existing punches in
the TDMA frame; however, this option eliminated the 14
carriers/sector limitation on the TDMA system.
1.3.4.1 OPTION 1 - GSM FEED SIGNAL TO TDMA WITH AN EXTRA DUPLEXER
CONFIGURATION
[GRAPHIC-OUTDOOR TWO ANTENNAS SYSTEM SHARING CONFIGURATION WITH AN EXTRA
DUPLEXER]
DETAIL CONNECTION
One antenna will be the Tx antenna for the TDMA system, and the
other one will be the TX antenna for the GSM system. Both antennas
receive signals for both systems.
The TDMA main Rx signal will be received from the GSM
duplexer/LNA/Splitter, an external attenuator, an external
duplexer, the internal TDMA duplexer, and then go into the TDMA
ERMC. The TDMA diversity Rx signal will be received from the GSM
duplexer/LNA/Splitter, an external attenuator, and then go into
the TDMA ERMC. The TDMA Tx signal goes to the internal TDMA
duplexer first, then goes through an external duplexer, and then
goes through the GSM duplexer, and sends the Tx signal to the
antenna. This configuration requires the TDMA Tx signal to go
through the GSM duplexer, which limited the TDMA total Tx power to
be 100w, thus, only 14 radios/sector can be configured for each
sector with average power of 7w/carrier.
The setting for the external attenuators may need to be adjusted
based on the field measurement.

gain because the GSM Rx connectivity remains the same between
sharing and non-sharing.

Impact to System Gain 3.231 1
13
With the insertion of an attenuator on the main Rx path and on the
diversity path, one can conclude that the impact on the NF can be
reduced to a minimum by checking the Impact to System NF (both
show OdB difference for main and diversity); one can also conclude
that there will be around 3dB gain on the Rx path by checking the
impact to System Gain (-3.23 for the main Rx path, and - 3.23dB on
the diversity Rx path).
With a 3.23dB gain on the Rx signal, up link RF parameter
adjustment is needed to maintain existing TDMA system performance.
The HOTL value needs to be set 3 dB stronger for the non-MAHO
prescreening. For instance, if the HOTL was set to -80dB prior to
the sharing, the HOTL needs to be set to - 77dB after the sharing.
Another option that can accommodate the 3.23dB Rx gain is to set
the RSSI offset value in the TDMA radios.
TX POWER
GSM Tx power remains the same since the GSM Tx paths are unchanged
for the sharing.
For the TDMA system, there will be 2.1dB (0.3dB on external
duplexer, 0.7dB on cable from external duplexer to GSM duplexer,
and 1.1 dB on the GSM duplexer) Tx power loss due to the transmit
signal going through 3 duplexers. The ERP power can be adjusted to
minimize the Tx power change if there is enough power on the ERP.
IM (CASCADED LNAs)
IM will slightly degrade with the sharing due to:
o Input IP3 may change; however, due to current product has
a high margin on IP3 point, the change is still within the
limit of the IS 136 and GSM 05.05 compliancy.
o With an added attenuator between LNAs to compensate for the
first LNA gain, the second LNA should not be overdriven.
14
NOISE FLOOR
Since the GSM Rx path remains the same, the GSM noise floor
remains unchanged for the sharing.
TDMA Noise floor is changed 3dB with the antenna sharing. In the
event the NSTHRESH is set to an absolute value, the value will
need to be adjusted to eliminate the noise floor impact. For
instance, if the NSTHRESH was set to - 100dB before the sharing,
the NSTHRESH should set to -97dB after the sharing. The signal to
noise ration (S/N) is not affected by the sharing since the RSSI
of the signal also changes, and the amount of the change between
noises and signal are the same.
RF COVERAGE
There will not be any RF coverage impact on the GSM system.
There are about 0.5dB degradation on GSM sensitivity, and less
than 1dB degradation on TDMA sensitivity due to the change of
linearity, IM, and interference; but the receive sensitivity is
still in compliance with GSM05.05 and IS 136.TDMA Tx power is
impacted with this configuration. There is 2.1 dB Tx power loss
due to the extra external duplexer; also, because the TDMA Tx
signal goes through the GSM duplexer, and the GSM duplexer is
limited to 100W, the TDMA Tx power is limited at the GSM duplexer.
1.3.4.2 OPTION 2 - CROSS FEED SIGNAL
CONFIGURATION
[GRAPHIC-OUTDOOR TWO ANTENNAS SYSTEM SHARING CONFIGURATION]
DETAIL CONNECTION
One antenna is directly connected to the TDMA system to transmit
and receive TDMA signal. This antenna is also to act as the GSM
diversity antenna to receive GSM signal. The GSM diversity signal
goes through the TDMA ERMC, an external attenuator, the GSM
duplexer/LNA/Splitter, and an internal 4dB fixed Pad.
The other antenna is directly connected to the GSM system to
transmit and receive GSM signal. This antenna is also to act as
the TDMA diversity antenna to receive TDMA signal. The TDMA
diversity signal goes through the GSM duplexer/ LNA/splitter, an
external attenuator, and the TDMA ERMC.
The external attenuators can be placed in either the TDMA or GSM
cabinet for weatherproof purposes.
15
The setting for the external and internal attenuators may need to
be adjusted based on the field measurement.
This option requires knocking out one of the six pre-existing
punches in the TDMA frame.

NOISE FIGURE (NF) AND RX SIGNAL GAIN
With the GSM diversity receiver going through the TDMA system, the
impact for GSM NF and Rx signal gain can be reduced to a minimum
by inserting a pad before the Rx signal goes into the GSM
duplexer, and another 4dB fixed pad after the GSM duplexer.

and 5.4dB for the stand alone one). The difference on gain for the
diversity Rx path is 1.27dB by comparing the gain from Antenna
Jumper to DRX on both tables (26.81 dB vs. 25.44dB).
With the TDMA diversity Rx signal going through the GSM system,
the TDMA NF and Rx signal gain is also affected by the sharing,
and the insertion of an attenuator in front of the TDMA ERMC may
be necessary to minimize the impact.

Impact to System Gain 3.23
With the insertion of a 19.2dB attenuator (include cable and pad
to the ERMC) on the sharing configuration, one can conclude that
the impact on the NF can be eliminated by comparing the Sys NF on
the Antenna Jumper (both tables show 7.85dB); one can also
conclude that there will be a 3.23dB gain on the Rx path by
comparing the gain from antenna jumper to TRU (4.88dB vs. 1.65dB).
With a 3.23dB gain on the Rx signal, up link RF parameter
adjustment is needed to maintain existing TDMA system performance.
The HOTL value needs to be set 3 dB stronger for the non-MAHO
prescreening. For instance, if the HOTL was set
18
to -80dB prior to the sharing, the HOTL would need to be set to
-77dB after the sharing.
Another option is to set the RSSI offset value in the TDMA radios.
Also, one can increase the step attenuator inside of the ERMC to
offset the gain.
TX POWER
Both GSM and TDMA Tx power are not affected by the sharing since
the path for the Tx antenna for both systems are the same as the
stand alone one.
IM (CASCADED LNAS)
IM will slightly degrade with the sharing due to:
o Input IP3 may change; however, due to current product has
a high margin on IP3 point, the change is still within the
limit of the IS 136 and GSM 05.05 compliancy.
o With an added attenuator between LNAs to compensate for the
first LNA gain, the second LNA should not be overdriven.
NOISE FLOOR
GSM Noise floor could have minimum impact (1.27dB).
TDMA Noise floor is changed 3dB with the antenna sharing. In the
event the NSTHRESH is set to an absolute value, the value will
need to be adjusted to eliminate the noise floor impact. For
instance, if the NSTHRESH was set to - 100dB before the sharing,
the NSTHRESH should be set to -97dB after the sharing The signal
to noise ratio (S/N) is not affected by the sharing since the RSSI
of the signal also changes, and the amount of the change between
noises and signal are the same.
RF COVERAGE
There will not be any RF coverage impact on GSM and TDMA forward
path.
There are about 0.5dB degradation on GSM sensitivity, and less than 1dB
degradation on TDMA sensitivity due to the change of linearity, IM, and
interference; but the receive sensitivity are still in compliance with GSM05.05
and IS 136.
1.3.5 1900 TWO ANTENNAS AND COAXIAL CABLE EQUIPMENT SHARING (OUTDOOR)
1900 MHz antenna sharing requires both GSM and TDMA system to be
on the same band due to the TDMA IRM filter is band pacific but
the GSM duplexer is not. For instance, if the GSM frequency is in
D band, the TDMA frequency has to be in D band as well.

With insertion of a lOdB attenuator (include cable and pad to the
IRM) and a fixed l0dB pad after the IRM on the sharing
configuration, there will be 0.91dB NF impact on the TDMA system
(Sys NF on the Antenna Jumper is 5.84dB vs. 4.93dB); one can also
conclude that there will be 4.62 gain on the Rx path by comparing
the gain from antenna jumper to TRU (17.1 dB vs. 12.48dB).
With a 4.62dB gain on the Rx signal, up link RF parameter
adjustment is needed to maintain existing TDMA system performance.
The HOTL value needs to be set 5 dB stronger for the non-MAHO
prescreening. For instance, if the HOTL was set to -80dB prior to
the sharing, the HOTL needs to be set to - 75dB after the sharing.
Another option is to set the RSSI offset value in the TDMA radios.
TX POWER
Both GSM and TDMA Tx power are not affected by the sharing since
the path for the Tx antenna for both systems is the same as the
stand alone one.
IM (Cascaded LNAs)
IM will slightly degrade with the sharing due to:
o Input IP3 may change; however, due to current product has
a high margin on IP3 point, the change is still within the
limits of the IS 136 and GSM 05.05 compliancy.
o With an added attenuator between LNAs to compensate for the
first LNA gain, the second LNA should not be overdriven.
NOISE FLOOR
GSM Noise floor could have minimum impact (0 .02dB).
23
TDMA Noise floor is changed 5dB with the antenna sharing. In the
event the NSTHRESH is set to an absolute value, the value will
need to be adjusted to eliminate the noise floor impact. For
instance, if the NSTHRESH was set to - 100dB before the sharing,
the NSTHRESH should be set to -95dB after the sharing. The signal
to noise ratio (S/N) is not affected by the sharing since the RSSI
of the signal also changes, and the amount of the change between
noises and signal are the same.
RF COVERAGE
There will not be any RF coverage impact on GSM and TDMA forward
path.
There will not be any reverse path impact on the GSM system.
There is less than 1dB degradation on TDMA sensitivity due to the
change of linearity, IM, and interference; but the receive
sensitivity is still in compliance with IS 136.
TDMA Tx power is not changed for this configuration.
2 CONCLUSION
Following are the conclusions for the TDMA/GSM antenna sharing:
o Overall, antenna sharing has a minimum impact to the RF
coverage as shown in the following table:
# of TDMA GSM
Band Antenna BTS Type BTS Type RF Coverage
---- ------- -------- -------- -----------
850 3 NT800 S8000 No RF Coverage Impact on GSM system;
