2 System Description
2.1 Overview
Mobile Advantage functions as an extension of wired communication
systems with additional mobile capabilities. Wireless systems provide the
same services as most commonly used Private Branch Exchange (PBX), with
the advantage of portable telephone capabilities. Mobile Advantage extends
normal mobile systems functions to operate inside buildings, factories, and
other internal sites.
Mobile Advantage mobile phones operate in either the 850 MHz (Cellular) or
1900 MHz Personal Communications Service (PCS) bands. To function in the
Mobile Advantage environment, mobile phones must be compatible with the
TDMA-136 standard protocol and have Adaptive Code Excited Linear
Prediction (ACELP) speech capability. ACELP is a speech coding and
decoding standard for mobile phones. For more information about the
TDMA-136 standard see “Appendix B—Acronyms and Abbreviations”, on
page 72.
Mobile Advantage users within the Mobile Advantage area use a private
numbering plan for calls to other Mobile Advantage users. Mobile Advantage
users communicate with public telephones through a PBX link connected to
the Public Switched Telephone Network (PSTN).
Mobile Advantage is associated with the Public Land Mobile Network
(PLMN) where the users are defined as standard cellular or PCS subscribers
in a Home Location Register (HLR). The subscription of users with the
PLMN allows Mobile Advantage users to roam outside the Mobile Advantage
area as normal cellular phones. The PLMN and the Mobile Advantage
authenticate mobile phone users by accessing an HLR connected to the
Common Channel Signaling System Number 7 (SS7) Network. To access the
HLR, Mobile Advantage is connected to the SS7 Network through a WOS
(Wireless Office System) SS7 Gateway link.
The associated PLMN notifies Mobile Advantage when a user is roaming in
the network. Mobiles entering or initializing in the system area notify Mobile
Advantage with a Private System Identification (PSID). Only mobile phones
defined to the Mobile Advantage system can function fully within a Mobile
Advantage environment.
Mobile Advantage can be configured to accept and transfer emergency calls,
such as E911 calls, from any mobile phone operating within the Mobile
Advantage coverage area. The mobile phone making the emergency call must
be compatible with TDMA-136 standard protocol and have ACELP speech
capability.
Mobile Advantage Operations, Administration, and Maintenance (O&M)
functions are performed through World Wide Web (WWW) or host
connections. The O&M Client application allows Mobile Advantage System
Administrators to receive operational information and administer the system
remotely.
The major physical components of the Mobile Advantage system are as
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
198 17-HRC104 201 PA9 9 (80)
follows:
•Mobility Server—The Mobility Server is a commercial server running
Ericsson open and scalable software on the Windows NT 4.0 operating
system. The Mobility Server connects to the Cellular Radio Exchange
(CRE) for configuration and administration of the Radio Infrastructure
(RI) and real-time tasks such as call switching.
The Mobility Server also provides the interfaces to the WOS SS7 Gateway
and the Internet. The bearer for both interfaces is Transport Control
Protocol/Internet Protocol (TCP/IP). The protocol to the SS7 network is
ANSI-41 Rev D.
•Cellular Radio Exchange (CRE)—The CRE, directed by the Mobility
Server, provides the physical interface between mobile phones in the
system area and the external PSTN through PBX links. Connections
between mobile phones operating in the system area are switched within
Mobile Advantage without accessing external networks. Mobile
Advantage supports the following PBX links:
-
T1 links to PBXs compatible with the Lucent Technologies 4ESS or
5ESS-2000 switch as specified in Lucent document 235-900-342.
-
T1 links compatibly with AT&T network-side Primary Rate
Interface (PRI) as specified in (TR 41 459) protocol.
-
Links to PBXs (for example, the Ericsson MD110) using the QSIG
protocol.
•Radio Heads (RH)—RHs connect to the CRE for communications with
Mobile Advantage mobile phones. RHs are placed at positions within the
Mobile Advantage area that provide maximum coverage and capacity.
Using multiple redundant RHs in an area will increase call handling
capabilities, as well as assuring continued call processing capabilities in
the event of a single RH unit failure.
•Scanners—Scanners also connect to the CRE and provide frequency
information for neighboring PLMN cells to Mobile Advantage.
Information obtained by Scanners is used by the system to minimize
interference from Mobile Advantage on PLMN frequencies.
•Mobile Phones—Mobile Advantage mobile phones are cellular or PCS
phones that are compatible with TDMA-136 standard protocol and
capable of ACELP speech encoding.
2.2 Mobile Advantage Mobile Phone User Features
Within the Mobile Advantage area, a registered user has access to the
following features:
•Personal Assistant (PA)—Allows the user the capability to change the
personal service profile. PA can be administered from any phone with
voice menus or through a WWW interface. If PA is administered from a
phone other than the user’s phone, a Personal Identification Number
(PIN) code must be entered.

terminals. The forwarding destination is determined by the Mobile
Advantage user’s current active profile.
•Caller’s Control—Allows the calling party to select a preferred
answering treatment from either a terminal or voice mail system.
•Three-Party Call Service—Allows a user to access Inquiry, Refer Back,
and Transfer features as follows:
-
Inquiry allows a user who is engaged in a two-party call to initiate a
call to a third party.
-
Refer Back allows the controlling party engaged in a three-party call
to switch between the active line and the held line.
-
Call Transfer allows the controlling party in a three-party call to
transfer the call to the other users and disconnect.
• Call Waiting—Notifies the user engaged in a two-party call that there is
an incoming call waiting. The user may do any of the following:
-
Disconnect the active call and accept the incoming call.
-
Place the active call on hold and accept the incoming call.
-
Ignore the incoming call. The incoming call will be forwarded to the
answering treatment defined with the PA.
•Calling Line Presentation and Restriction—Allows the calling number to
be presented to the user. If the calling party is a Mobile Advantage user
calling a Mobile Advantage user within the system area, the DUN is
presented. If the called party is outside the system area, the DID number
is sent. Mobile Advantage can be configured to substitute a general
number or restrict presentation of DID numbers.
•PBX Voice Mail—Allows calls to a user to be forwarded to the PBX
voice mail system. Mobile Advantage users can also use the voice
mailbox when roaming in the PLMN.

2.4.2.2 CRE Component Descriptions
The component descriptions and slot assignments of the boards in the CRE
main and auxiliary cabinets are as follows:
•The CRE backplanes have 11 connecting slots that route signal and
power busses to the boards. A ribbon cable connects the backplanes
together in two-cabinet installations.
•The Synchronization (SYNC) board is inserted into slot one of the main
cabinet. The SYNC board provides system timing to all CRE boards
except the SWB. Only the CRE main cabinet requires the SYNC board.
•The CRE Power Module (CPM) boards, located in slot two in both the
main and auxiliary cabinets, provide the power to all of the boards in each
cabinet. The CPM and SYNC boards have the component side facing left
when viewed from the front; all other boards have the component side
facing right. The CPM boards convert the -48 Vdc local power input to
+5 Vdc and +3 Vdc outputs to the power bus on the backplanes. The CPM
boards also supply -48 Vdc to the SWB, SYNC board, and all Radio Link
Unit (RLU) boards, except the RLU board in slot three.
•Radio Link Unit (RLU) boards receive clock signals from the backplane
and provide clock signal synchronization and data transfer to the Radio
Heads (RH) and Scanners. RLUs perform pre-processing of Radio
Network Control (RNC) measurements and TDMA-136 formatting.
Each RLU can be connected to a maximum of eight RHs or Scanners. A CRE
can be configured with a maximum of four RLUs to support a total of 32 RHs
or Scanners. RLUs supply remote power through CAT 5 cables to RHs
mounted less than 800 meters (2640 feet) from the CRE. RLUs also provide
remote power to Scanners located less than 1200 meters (3960 feet) from the
CRE.
•The RLU board, located in slot three of the main cabinet, functions as a
central processor, providing Call Control, Radio Network Control, and
O&M configuration to the CRE.
Note: Do not attach RLU cables to the connectors of an RLU board
when it is inserted in slot three of the main cabinet.
•The Signal Processing Unit (SPU) board performs the Digital Control
Channel Handler (DCCH) functions and Digital Traffic Control (DTC)
handler functions. The DTC handler establishes and maintains traffic
channels. A single SPU can process seven simultaneous calls. Additional
SPUs can process eight simultaneous calls each. Using multiple SPU
boards provides a pool of time slot handlers that are dynamically
allocated to calls in progress. SPU boards also provide the following
features:
-
Channel coding and decoding
-
Speech coding and decoding
-
Echo canceling
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)

•The Digital Trunk Unit (DTU) board, in slot nine of the main cabinet,
interfaces with two E1 links to the SWB board and decodes the speech
and data busses. The two E1 links provide 60 full-duplex voice channels.
•The SWB, in slots 10 and 11 of the main cabinet, connects Mobile
Advantage to the local PBX and performs call switching. Up to six links
are configurable between the SWB and the PBX. The physical interfaces
between the SWB and the PBX are twisted pair, 120 ohm (E1) or 100
ohm (T1) balanced cables.
2.4.3 Radio Heads (RH)
Ericsson recommends vertical mounting of RHs on internal walls in the
Mobile Advantage coverage area. Each RH provides five transceivers for air
interface communications with mobile phones using the TDMA-136
protocol. In a typical office environment, an RH has a typical coverage radius
of 40 meters (132 feet).
RHs are connected with CAT 5 cables through punch blocks to RLU boards
in the CRE. RHs receive control, data, and power through the RLU boards if
located less than 800 meters (2640 feet) from the CRE. RHs with longer cable
runs (up to1600 meters or 5280 feet) from the CRE, must be provided with a
115 Vac to 24 Vdc power converter.
2.4.4 Scanners
Scanners connect to RLU boards in the CRE and provide neighboring cell
PLMN frequency usage information to Mobile Advantage. Information from
the Scanners is used by Mobile Advantage to minimize interference on
Mobile Advantage and PLMN frequencies.
Scanners are connected with CAT 5 cables through punch blocks to RLU
boards in the CRE. Scanners receive control, data, and power through the
RLU boards if located less than 1200 meters (3960 feet) from the CRE.
Scanners with longer cable runs (up to1600 meters or 5280 feet) from the
CRE must be provided with a 115 Vac to 24 Vdc power converter.

3 Site Planning
Site planning evaluates the capacity needs of the Mobile Advantage system
and optimum placement of the components. The Mobile Advantage coverage
area is considered to be one cell.
In the planning phase the customer must complete a Site Planning Checklist
provided by Ericsson. Alternately, the customer can order a Site Survey to be
performed by Ericsson trained personnel to fulfill the following site planning
requirements:
•Determine the amount, location, and power requirements of the Mobility
Server, the CRE cabinets, Radio Heads, and Scanners.
•Define the external links and protocols required for Mobile Advantage to
communicate with the Private Telephone Network (PTN), the Internet,
and the Public Land Mobile Network (PLMN).
•Specify all cabling requirements within and external to the Mobile
Advantage system. List what components are supplied with the Mobile
Advantage system and what components are to be purchased locally.
•List any environmental requirements, distance limitations, and capacity
determinations.
3.1 Site Capacity and Reliability
The maximum physical coverage area and simultaneous call capacity
requirements determine unit configuration. A fully configured system can
process a maximum of 60 simultaneous calls.
Mobile Advantage can process 45 Erlang traffic at a Grade of Service (GOS)
of 0.5 percent. A GOS refers to the percentage of calls that could be blocked
during maximum traffic times. For example, at a GOS of 0.5 percent, Mobile
Advantage can process calls for up to 448 users if traffic for each user is
approximately 100 mErlang.
When estimating the maximum capacity in call processing of a Mobile
Advantage site, allowances should be made for redundant capacity. For
example, the call processing capabilities of SPU boards are added together in
the CRE to provide a pool of processing resources. When determining the
number of required SPU boards, allowing for extra capacity will, in the event
of an SPU board failure, maintain the GOS.
Estimated internal and external traffic requirements will determine the
required number of physical links from the CRE to PBXs or other units.
3.2 Mobility Server Planning
The Mobility Server component in Mobile Advantage is specified by Ericsson
to support all possible configurations of the system. Site planning for the
Mobility Server consists of estimating the power requirements and
connections to Mobile Advantage components and external links. All TCP/IP
connections information, including IP addresses of the connecting ports, must
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
20 (80) 198 17-HRC104 201 PA9
be entered in the Site Planning Checklist for use in the Mobile Advantage
installation and initialization phases.
The Mobility Server is powered by redundant -48 Vdc power supplies. The
type and location of all power requirements must be predetermined during the
site planning.
3.2.1 Mobility Server Connections
The following connection information is entered into the Site Planning
Checklist during the Mobile Advantage site planning phase:
•To enable remote WWW O&M access to Mobile Advantage, a TCP/IP
connection to the Internet on a local LAN, dedicated router, or
communications server must be supplied.
•To access the HLR in the SS7 network, a connection must be supplied
from the Mobility Server to a WOS SS7 Gateway Server. The protocol is
ANSI-41 Rev D; the bearer is TCP/IP on Ethernet.
•Two Ethernet connections are required from the Mobility Server to the
CRE main cabinet. Two reverse CAT 5 cables with RJ-45 connectors are
supplied with the system. The Ethernet connections are from the Mobility
Server to:
-
the RLU board inserted in slot three of the CRE main cabinet, and
-
the SWB inserted in slot 10 and extending over slot 11 of the main
cabinet. The SWB board requires two slots spaces.
3.3 Cellular Radio Exchange (CRE) Planning
The CRE for Mobile Advantage is configured in one or two cabinets. The
CRE auxiliary cabinet must be installed to the right of the CRE main cabinet.
The quantity of cabinets required must be determined in the site planning
phase.
Note: When installing single-cabinet systems allocate space to the right of
the main cabinet for an expansion cabinet.
In Mobile Advantage a main and one auxiliary cabinet can support the
maximum quantity of system boards (SPU and RLU). Site planning
determines the optimum quantity of each board. Adding extra SPUs, RLUs,
or RHs to Mobile Advantage can provide redundancy in coverage and
processing capabilities in event of failure. The maximum number of Mobile
Advantage CRE boards are as follows:
•Eight SPU boards—The first SPU board can process seven simultaneous
calls. Each additional board can process eight calls except the eighth
which can process five calls (7+8+8+8+8+8+8+5 = 60). Eight SPU
boards provide a processing pool capable of handling a total of 60
simultaneous calls.
•Four RLU boards—Each RLU board can support a maximum of eight
RHs. Each RH can process a maximum of 14 simultaneous calls.
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
198 17-HRC104 201 PA9 21 (80)
Note: The amount of RLU boards configured will determine the amount
of punch blocks required. Each RLU board is cabled to one punch
block. Placement of the punch blocks is also determined during
site planning.
3.3.1 CRE connections
The amount, type, and location of the CRE connections are determined in the
site planning phase. The following information is considered when
completing the Site Planning Checklist:
•Mobile Advantage supports a maximum of six external T1 or E1 trunk
links between the SWB and PBXs.
Note: E1 or T1 cables, 15 meters (50 feet) in length, are supplied with
the system for connections to equipment located in the same room
as the CRE. The connectors of the cables supplied by Ericsson
meet specific shielding requirements to comply with radiated
emissions regulations. If the location of PBXs require extensions,
they must be connected to the cables supplied by Ericsson, to
meet requirements.
•Two standard RLU telephony cables are supplied for use between each
configured RLU board and the punch blocks. Each punch block is
connected to a maximum of eight RHs or Scanners with standard CAT 5
cables.
Note: When connecting the cables to RLU boards consider whether
redundant RH coverage is necessary. When locating an RH near
another RH, to provide for redundant coverage in an area, do not
connect to the same RLU board. The failure of a single RLU
would not cause loss of coverage if redundant RHs are connected
to different boards.
•-48 Vdc power cables are supplied for each cabinet.
•A PE ground cable is supplied for each cabinet.
•Two Ethernet connections are required from the Mobility Server to the
CRE main cabinet. Reverse CAT 5 cables with RJ-45 connectors are
supplied with the system. The CAT 5 cables are connected from the
Mobility Server to the following:
-
The RLU board located in slot three of the CRE main cabinet.
-
The SWB in the CRE main cabinet. The SWB is inserted in slot 10
and extends over slot 11 of the main cabinet.
3.4 RH Planning
The number of required Radio Heads is determined by analyzing physical site
requirements and user location estimates. Estimating the location and number
of RHs is determined using site floor plans. A method of determining the level
of external radio interference is used. The level of radio interference measured
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
22 (80) 198 17-HRC104 201 PA9
during site planning will effect the planned number of RHs, the RH
transmitted power, and maximum mobile phone power. Higher external radio
interference levels require more RHs.
The number of RHs must be sufficient to perform the following:
•Provide the necessary carrier to noise levels ratio
•Allow low enough transmitted power level to minimize interference to
external systems
•Provide call completion without blocking for the estimated number of
users in all areas. An RH can be mounted near another RH in areas where
large concentrations of users are predicted or redundant coverage is
needed.
3.4.1 Estimating Radio Coverage
The customer’s desired radio coverage area must be understood before a
system quotation can be provided. Radio coverage is provided by the strategic
placement of Radio Heads and Scanners. The Mobile Advantage system can
support up to 32 Radio Devices: RHs and Scanners. Coverage can be
estimated using the following three methods, shown in order of increasing
reliability.
1. Square footage estimate
The configuration provides an estimate of how many square feet a given
number of Radio Heads will cover. Although it is possible to provide
budgetary quotations from square footage alone, this is not recommended.
2. Floor plans
If provided with floor plans, Sales Engineering can formulate a more accurate
estimate of how many Radio Heads and Scanners are required to cover a given
facility. Quotations based solely upon floor plans must include a provision
stating to the customer that the actual number of Radio heads required may
vary (higher or lower). Ericsson will not guarantee coverage based solely
upon floor plans. If a firm quotation is required, a Site Survey must be ordered
from the Ericsson Service Group.
3. Site Survey
A Site Survey is the most accurate way to assess needed radio coverage.
Using the TEMS™ radio Site Survey tool, an Ericsson-trained technician will
walk through a customer’s facility taking measurements to ensure the optimal
placement of Radio Heads. A Site Survey will usually be employed in the
later stages of the sales process but prior to making any contractual
agreements.
3.4.2 RH Connections
RHs are connected by solid wire CAT 5 cables to designated pins on the
punch blocks. For more information about RH cabling see “Appendix A—
Cabling and Connectors”, on page 58.
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
198 17-HRC104 201 PA9 23 (80)
Note: Local RHs located less than 800 meters (2640 feet) from the CRE
receive power from the RLU boards through the CAT 5 cables. RHs
located 800 to 1600 meters (2640 to 5280 feet) from the CRE must
have a 115 Vac outlet located nearby.
3.5 Scanner Planning
The number and location of required Scanners are determined by analyzing
physical site requirements and macro cell interference studies. A minimum of
two Scanners are required for each Mobile Advantage system.
3.5.1 Scanner Connections
Scanners are connected by solid wire CAT 5 cables to designated pins on the
punch blocks. For more information about Scanner cabling see “Appendix
A—Cabling and Connectors”, on page 58.
Note: Scanners located less than 1200 meters (3960 feet) from the CRE
receive power from the RLU boards through the CAT 5 cables.
Scanners located 1200 to 1600 meters (3960 to 5280 feet) from the
CRE are powered by a 24 Vdc converter and must have a 115 Vac
outlet located nearby.

“Installation,” on page 27 followed by Chapter 6, “Integration and
Test,” on page 36, to complete the Mobile Advantage installation.
4.1 Environmental Requirements
CRE cabinets are to be mounted on an indoor wall on a panel that is secured
to wall studs. The premises must comply with the following prerequisites:
•The ambient air must be free of dust, smoke, gases and acid fumes.
•The temperature range where the CRE and Mobility Server are located
must be between +5°C and +40°C and relative humidity may vary
between 15% and 80%.
•The temperature range where the RHs and Scanners are located must be
between 0°C and +55°C with a relative humidity of up to 100%
non-condensing.
Note: Sensors within the RHs and Scanners monitor temperature levels
and will shut down at elevated levels.
•The relationship between temperature and air humidity in the Mobile
Advantage area must not cause condensation.
•The CRE should not be exposed to direct sunlight
•Cables should run into the CRE from below the cabinet to ensure
sufficient air flow and space.
If batteries are in the room where Mobile Advantage components are located,
they must be of such type that does not produce gases or acid fumes.
Note: Auxiliary cabinets must be installed to the right of the main cabinet
(cabinet one). When installing a single-cabinet or a two-cabinet
system, leave room to the right for adding expansion cabinets.
4.2 Power Requirements
The following power sources are required.
•The Mobility Server is powered with a -48 Vdc power source. The -48
Vdc power is supplied from the PBX battery regulated supply or from a
separate Uninterruptible Power Source (UPS).
•The CRE must be supplied with -48Vdc from the PBX battery regulated
supply or from a separate UPS.
•Each RH or Scanner requires a power source. RHs located less than 800
meters (2640 feet) from the CRE, receive power remotely from the RLU
boards through the CAT 5 cables. Scanners located less than 1200 meters
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
198 17-HRC104 201 PA9 25 (80)
(4356 feet) from the CRE, also receive power from the RLU boards. If
RHs or Scanners cable distances are longer (up to1600 meters or 5280
feet) they receive power from a 24 Vdc converter. A 115 Vac outlet must
be located nearby to supply power to the converters, if used to power RHs
or Scanners.
4.3 RH and Scanner Cable Installation
Before beginning the procedures in this section, print a copy of Chapter 11,
“Appendix A—Cabling and Connectors,” on page 58, to use with all
installation procedures.
Installing the cables and punch block wiring for the RHs and Scanners can be
done before receiving the main Mobile Advantage units. The physical
requirements of the Mobile Advantage area and the planned location of the
RHs or Scanners from the site planning phase determine the best cable
routing.
Note: Cables that are routed through ceilings or plenums must be rated for
fire safety. The applicable cable plenum specifications are defined in
NEC CMP and CSA PCC FT4/FT6.
4.3.1 Installing Cables From The CRE to RHs or Scanners
Perform the following steps to correctly install the RLU cables from the RLU
boards to the punch blocks and CAT5 cables from the punch blocks:
1. Determine the number and location of the RHs, Scanners, punch blocks,
and CRE cabinets from the site planning documents.
2. Install the required amount of punch blocks in the correct location. Punch
blocks are usually installed on wall-mounted panels or racks.
3. Attach labels to the punch blocks to identify which functional RLU
board (for example, RLU1 to RLU4) will be connected to the punch
block.
Note: When cabling from the RLU boards to punch blocks, do not
connect to the RLU board in slot three of the main cabinet. The
RLU board in slot three functions as a central processor and is not
connected to RHs or Scanners.
4. If the RLU to punch block cables supplied with the system are available,
label and connect them to the designated punch blocks.
Note: The cable from the top telephony connector (DB-37) on each
RLU board routes to the telephony connector on the top left side
of the designated punch block. The cable from the bottom
telephony connector on each RLU board routes to the connector
on the bottom right side of the designated punch block.
5. Route the customer supplied CAT 5 cables from the positions of up to
eight RHs or Scanners to the designated punch block.
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
26 (80) 198 17-HRC104 201 PA9
Note: Redundant RHs covering the same area should not be connected
to the same RLU board. Connecting redundant RHs to separate
punch blocks and RLU boards allows for continuing coverage of
an area in case of RLU board failure.
6. Attach identification labels to both ends of the designated CAT 5 cables
indicating the connections (for example, RHx through RHy).
7. If the RHs or Scanners are installed, connect the RJ-45 connector ends
of the CAT 5 cables.

6 Integration and Test
Integration of the Mobile Advantage consists of configuring the system and
allocating the frequencies to be used. After integration is complete the Mobile
Advantage is initialized and can provide call services.
6.1 Integration
The integration phase follows the physical installation of Mobile Advantage
and ends when all necessary configuration data is entered. The CRE IP
address must be set before O&M tasks can be executed. Configuration data
that is not pre-defined is manually entered by the O&M user.
Configuration data entered by the O&M User is divided into the following
categories:
•Security Data—User Identification, Password, and Access Level
•Radio Network Data—Radio network frequencies and control
parameters
Note: Some parameters cannot be changed by the user, but are only
accessible in a configuration file which is managed by the system.
•Call Control Data—PBX Prefix and External Line Prefix
•Network Data—Trunk Line, Routes, and Interface Protocol Timers
•Subscriber Data—Subscriber name, Mobile Identification Number
(MIN), DWOS User Number, and Service Profile.
Note: For more information about configuring Mobile Advantage see
Chapter 8, “Operations, Administration and Maintenance
(O&M),” on page 42.
6.1.1 Initial frequency selection
The initial frequencies allocated to Mobile Advantage are determined by the
cellular operator. For site planning Ericsson provides a Site Survey service to
identify the best initial frequencies. During normal operation automatic
frequency allocation software determines the optimum frequency usage with
Scanners.
6.1.2 Mobile Advantage Initialization
The Mobile Advantage system is initialized by executing the following steps:
1. Turn ON the Mobility Server.
2. Obtain the CRE IP addresses and Bootfile name from the Site Planning
Checklist.
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
198 17-HRC104 201 PA9 37 (80)
Note: Configure the fixed SWB IP interface address (IP=172.16.2.50
Subnet Mask=255.255.0.0). The IP address of the RLU board in
slot three of the main cabinet is automatically configured when
the CRE is turned on if the Mobility Server NIC port is connected.
3. Turn ON power to the CRE. The Mobility Server indicates the CRE
status is UP and transfers the Bootfile information.
Note: For information about using other O&M functions after Mobile
Advantage is started see Chapter 8, “Operations, Administration
and Maintenance (O&M),” on page 42.
4. If there are RHs or Scanners located too far from the CRE to use its
power, then the 115 Vac which operates the power converters must be
be on for those units.
6.1.3 The ANSI-41 Link to the HLR
To access the HLR, Mobile Advantage connects through a WOS SS7
Gateway to the SS7 network. The ANSI-41 link provides administrative and
messaging between the Mobility Server and the WOS SS7 Gateway.
Administrative messages include heartbeat and initial configuration
messages. Heartbeat messages indicate the state of connections between the
Mobility Server and the ANSI-41 system. After configuration is complete the
Mobility Server can generate and respond to heartbeat messages.
The Mobility Server configuration message is received from the WOS SS7
Gateway system after initial establishment of the TCP/IP connection. The
Mobility Server is a client node to the WOS SS7 Gateway system and has to
send the initial connect() message to establish connection.
6.1.3.1 Setting the ANSI-41 TCP/IP Interface
Obtain the WOS SS7 Gateway IP addresses from the Site Planning Checklist.
At the selection of ANSI-41 in the “Hardware Resources” service area of the
Management System interface, enter the following data:
•The identity or name of the link
•The primary and secondary IP addresses and port numbers of the WOS
SS7 Gateway.
•The number of heartbeat failures before the interface between the
Mobility Server and the WOS SS7 Gateway is closed.
•The heartbeat time out interval in seconds.
•The link protocol (ANSI-41)

7 Numbering Plans
Mobile Advantage provides one-number access to all users whether they are
in the system area or roaming in the PLMN. The 10-digit Direct In Dialing
(DID) number can access a Mobile Advantage user whether in the system area
or roaming in the PLMN. While in the system area, calling users can connect
to other users with a four or five-digit DWOS User Number (DUN), a subset
of the DID number. When Mobile Advantage mobile phone users in the
system area call external numbers the Calling Line Identification Presentation
(CLIP) to the called party is the DID number, unless an alternative number is
defined.
Administration and billing for Mobile Advantage users is simplified by the
one-number access capabilities. The Mobile Advantage and associated
PLMN determine system costs; the user is not billed for calls originated from
or destined to Mobile Advantage numbers. Although a Mobile Directory
Number (MDN) is assigned by the PLMN to all Mobile Advantage phones, it
is not recommended for typical usage. Calls originated or destined for MDN
numbers are billed directly to the user.
The Mobile Advantage numbering plan uses the following:
•PBX Extensions—The PBX extension number defines a physical
extension of a Mobile Advantage mobile phone. A PBX Extension
number can only be used by subscribers connected to the PBX or Mobile
Advantage users while in the system coverage area.
•DWOS User Numbers (DUN)—The DWOS User Number defines only
Mobile Advantage mobile phones. A DUN is used by subscribers
connected to the PBX or within the Mobile Advantage coverage area to
call other Mobile Advantage users.
•PBX Prefix—The PBX Prefix is the office code of the PBX in the PSTN.
The PBX prefix is added to the DUN to make a seven-digit directory
number.
•Numbering Plan Area Code (NPA)—The NPA identifies the calling code
of an area of the country. To make a national call, the NPA Code is added
to the seven-digit directory number.
•Direct In Dialing (DID)—The DID number is composed of the
NPA+PBX Prefix+DUN numbers (for example 919 555 1212). The DID
is presented as the CLIP when a Mobile Advantage user calls out of the
system area.
•Country Code (CC)—The CC identifies the calling code of a country. To
make an international call, the CC is added to the ten digit DID.
•External Line Prefix—Some PBX systems require dialing a number to
access the external networks. For example, dialing a 9 to get an outside
line.

7.1 Examples of number usage
In the following examples the features; Follow Me In/Out and Calling Line
Identification Presentation (CLIP), of the calling and called phones are active.
The following examples describe Mobile Advantage number usage:
•A Mobile Advantage user in the system area calls another Mobile
Advantage user’s four or five-digit DWOS User Number (DUN). Mobile
Advantage then does one of the following:
-
If the called user is also in the system area, Mobile Advantage locates
the called mobile phone, completes the call connection, and presents
a CLIP consisting of the caller’s DUN to the called party.
-
If the called user is not in the system area, Mobile Advantage
interrogates the PLMN for the roaming routing number and
Temporary Local Directory Number (TLDN) to the called mobile
phone. The TLDN is temporarily allocated by a Mobile Services
Switching Center (MSC) for call setup and is used to route the call
through the PSTN or PLMN networks. Mobile Advantage locates
the called mobile phone, completes the call, and presents a CLIP
consisting of the caller’s Direct In Dialing (DID) number to the
called party.
•A Mobile Advantage user not in the system area calls another Mobile
Advantage user’s DID number. The call is routed through the PLMN and
PSTN to Mobile Advantage. Mobile Advantage then does one of the
following:
-
If the called user is in the system area, Mobile Advantage locates the
called mobile phone, completes the call connection, and presents a
CLIP consisting of the caller’s DUN to the called party.
-
If the called user is roaming in the PLMN, Mobile Advantage
interrogates the PLMN for the roaming routing number and TLDN
to the called mobile phone. Mobile Advantage locates the called
mobile phone, completes the call, and presents a CLIP consisting of
the caller’s DID to the called party.
•When a non-Mobile Advantage phone calls a Mobile Advantage user’s
DID number, the system does one of the following:
-
If the called user is in the system area, Mobile Advantage locates the
mobile phone, completes the call connection, and presents a CLIP
consisting of the caller’s DID number to the called party.
-
If the called user is roaming in the PLMN, Mobile Advantage
interrogates the PLMN for the roaming routing number and TLDN
to the called Mobile Advantage User. Mobile Advantage locates the
called mobile phone, completes the call, and presents a CLIP
consisting of the caller’s DID to the called party.
•When a Mobile Advantage user in the system area calls an external
number the call is connected through the PBX to the PSTN. After call
setup, Mobile Advantage sends a CLIP consisting of the caller’s DID to
the called party.
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
198 17-HRC104 201 PA9 41 (80)
•When Mobile Advantage mobile phone users are not in the system area,
calls to external numbers are routed through the PLMN and billed as
normal cellular calls to the user.
The following numbers codes and definitions are used in the examples shown
in table 1:
•PBX Prefix: 472
•External Line Prefix: 9
•Numbering Plan Area Code: 919
•Long Distance Code: 1
•User one: a Mobile Advantage mobile phone user with DUN 6600
•User two: a Mobile Advantage mobile phone user with DUN 6601
•User three: a fixed external user with PSTN number 919 456 3434
Note: The PBX to which Mobile Advantage connects must have a Private
Number Plan which includes the DWOS User Numbers. The PBX
must accept PBX extensions as Called Party IDs from Mobile
Advantage.

8.4 Service Areas
The O&M User specifies the different output criteria for operations. Different
criteria are, for example, when call information reports should be generated,
such as after every call, when call duration exceeds a predetermined time,
specific to the calling number, or the dialled number.
In this section, explanations are given for the O&M Client service areas in the
order they appear on screen. Examples of datafill for O&M forms are shown.
The O&M functions are divided into the following service areas:
8.4.1 Customer
The Mobile Advantage system can provide service to more than one
customer. In the Customer service area the following parameters are defined
for each customer:
•Customer Name is a unique name of no more than 50 characters. For
example, General_Hospital.
•Customer Number series contains sets of four or five-digit DWOS User
Numbers (DUN), assigned to this customer. For example, to define the
customer number series consisting of the numbers 845 1808 and 845
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
46 (80) 198 17-HRC104 201 PA9
1809 as a four-digit DUN, the datafill in the field “From” is 1808 and
field “To” is 1809. To define a five-digit DUN the datafill in field “From”
is 51808 and “To” is 51809. To add other number series use the Modify
submenu.
•Public Prefix field is the two or three-digit code prefacing the DUN
series, to allow access to Mobile Advantage users from external
networks. For example, a three-digit prefix (845) is added to the
four-digit DUNs (1808 and 1809).
•Common Answering Position number is either a DUN, within the
customer series, or a DID, to direct unanswered calls to.
•Personal Assistant (PA) is a DUN where the Mobile Advantage user can
access the personal number settings. Mobile Advantage responds to all
calls made to the PA with audio prompts explaining how to control
features from a Dual-Tone Multifrequency (DTMF) phone.
•Default Voice Mail address is a DUN used to access the Mobile
Advantage user’s voice mail services.
•The Initial Voice is picked from a list of options defining Mobile
Advantage user greetings.
•Trunk Call Discrimination (TCD) is used to prevent users from
originating calls to certain outgoing numbers.
•Traffic Matrix System (TMC) is similar to TCD, but applies only within
the Mobile Advantage area.
8.4.2 End User
Mobile Advantage allows creation of profiles for a single user or a group of
users in one operation. If a group of users are defined in one operation all users
will have the same name and profile. Default profiles that were defined in the
Customer Service area for users can be modified for each Mobile Advantage
user. To alter profiles, including changing the user names or numbers use the
Modify submenu.
In the End User service area a user’s access to Mobile Advantage can be
locked or unlocked and a password set or changed. Mobile Advantage users
can be created, modified, or deleted. When creating Mobile Advantage users,
the following parameters are defined:
•End user number can be a single DUN (for defining one user), or a range
of DUNs, that fall within the set of numbers previously defined for the
customer’s use.
•End user name associates a Mobile Advantage user name to a DUN. If a
range of DUNs were defined in End user number, all users in the group
will have the same name until modified. Creating a group of Mobile
Advantage users, then modifying names, results in a group of users with
multiple numbers to have the same or similar profiles.
•Trunk Call Discrimination (TCD) is defined for a Mobile Advantage user
only if different than the default TCD set in the Customer service area.
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
198 17-HRC104 201 PA9 47 (80)
•Traffic Matrix Coordinates (TMC) is defined for a Mobile Advantage
user only if different than the default TMC set in the Customer service
area.
•ID presentation restriction, if set to YES, allows the identification of the
DWOS User Number to be presented to the called party. The number
presented may be a DID or DUN determined by the Mobile Advantage
user’s physical location at the time of the call.
•Voice mail address is defined for a Mobile Advantage user only if
different than the default Voice mail address set in the Customer service
area. The voice mail address is the extension number to access the voice
mail service.
•Voice Mail subaddress contains the DID of the voice mail service.
•Features provides a list of Mobile Advantage user features or
combinations of features for the Mobile Advantage user to select from.
8.4.3 Personal Number services
Personal Number services allow Mobile Advantage users to control how
incoming calls are handled. The Mobile Advantage user can define multiple
profiles that determine the sequence of numbers to forward incoming calls,
screening of numbers, and call control. An excellent description of personal
number services is included in the Mobile Advantage on-line document
“Personal Number User Web Guide”. This guide is accessed from the
Personal Number main screen.
8.4.4 Route Handling
The service area “Route Handling” provides route and trunk definition from
lists of available resources and numbering plans. Routes can consist of
multiple trunks for traffic loading and redundancy. Before creating routes or
trunks physical links need to be created in the service area “Hardware
Resources”.
8.4.5 Hardware Resources
8.4.6 Fault Management
Fault management is covered in the section on “Troubleshooting”, on page
50.

8.4.7 Number Analysis
8.4.8 System Network
8.4.9 Call Logging
The “Call Logging” service area provides an accounting management
function which accumulates account information for all internal calls,
incoming calls, and outgoing calls. Mobile Advantage generates a call
information report for each completed call if the specified output criteria is
met. The reports are stored in a file which can be postprocessed outside
Mobile Advantage. Examples of call logging scenarios are available on-line
by selecting the link “Call Logging Condition Code Guide” at the Call
Logging main screen.
8.4.10 Performance
At the “Performance” service area, the available functions consists of
measurements, event recording and statistical evaluations. Traffic statistics
can be collected from the Mobility Server and the Radio Infrastructure (RI).
Mobility Server performance measurements can be made on extension
numbers, routes, or call forwarding transfers. In the sub-menu selection
“MobServer Measurements” the user can create, modify, browse, display, and
delete performance reports.
RI Measurements includes data collection, and data storage. The data
collection part is implemented in the CRE. Although the performance data
files are controlled by the CRE the actual files are stored in the Mobility
Server and are accessed by the CRE.
Configuration of Radio Network Recording parameters (for example
thresholds) is done at the “Radio Network” selection and transferred to the
CRE. A fault report is sent to the Mobility Server if a threshold is crossed. The
fault will then be treated as an alarm in the Mobility Server. Creating,
deleting, or modifying RI measurement reports is accomplished in the
“Performance” service area selection, sub-menu “RI Measurements”.

9 Troubleshooting
9.1 General
Mobile Advantage system faults are reported to the Mobility Server. At the
Mobile Advantage management interface screen the “Alarm Window” gives
a visual indication of active alarms. Access the fault and event logs by
clicking on the number displayed under the “Alarm Bell” indicator or by
selecting the “Faults” service area.
Writer’s Note: also see Overview student guide page 28.
The Mobility Server treats hardware faults, exceptional software faults and
crossing of performance thresholds as Alarm Reports. Software exceptions
such as process restarts are treated as Event Reports. An alarm remains active
until the fault has ceased, while an Event Report is information about
something that has happened and can also be used for reporting software
errors.
9.1.1 Start and restart
The CRE will always load a Bootfile from the Mobility Server at start and
restart. The CRE sends updated information to the Mobility Server about the
hardware when a restart occurs because the hardware configuration may have
changed (boards added or removed).
The Mobility Server will clear all active alarms after a restart. Any faults that
remain active after the restart will be reported as well as any new faults that
are detected.
9.1.2 System Backup
A consistent and periodic backup strategy can decrease system recovery time.
To order a backup of configuration data to the Mobility Server hard drive
select the “System” service area. The configuration data includes all
configurable data in the Mobility Server and the CRE. All configuration data
will automatically be restored after a restart of the system.
9.2 Fault Management
Mobile Advantage automatically detects hardware and software faults on
replaceable units, links and software modules. Fault reports are stored in the
alarm log or event log in the service area “Faults”. After detection Mobile
Advantage blocks the operation of faulty units or links. Replaceable hardware
units are, for example, RHs and boards in the CRE cabinet. Links are, for
example, the connections to the PBX.
Mobile Advantage uses visual system alarms to indicate when a new Alarm
Report or a new Event Report is generated. The system also indicates when
an existing Alarm Report is updated after correction of the fault. If the user is
not logged in to the Management System interface, the alarm or event data
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
198 17-HRC104 201 PA9 51 (80)
will be stored in the log files. To retrieve information about faults or events,
access the “Faults” service area which contains the logged alarm information.
Active alarms are indicated in the Current Alarms section until cleared. After
alarms are cleared the alarm histories are stored in the Alarm Log. Events are
stored in the Event Log. The following functions are implemented in the
Mobility Server regarding current alarms reports.
•Browse Current Alarms
•Modify (add information to) a current alarm report
•Delete Current Alarms
After an alarm is cleared (automatically or manually) the following functions
are available to review past alarms in the Alarm Log.
•Browse the Alarm Log
•Delete the Alarm Log
The following functions are implemented regarding the Event Log.
•Browse the Event Log
•Delete the Event Log
The following functions are implemented for all Registered Alarms.
•Browse Registered Alarms
•Modify Registered Alarms
Mobile Advantage automatically blocks faulty units and links. Links are
automatically deblocked when the faults have disappeared. The O&M User
can also manually block and deblock any units or links to localize faults. For
example, to take a link temporarily out of operation.
When a faulty CRE system component is replaced with a new unit and the
component is placed into operation, the corresponding Alarm Report is
updated automatically.
When severe software faults are detected, Mobile Advantage is automatically
restarted. The restart can be on different levels, such as:
•Board
•Radio head or Scanner
•Cellular Radio Exchange (CRE)
•Mobility Server
Note: In the most severe case the complete Mobile Advantage is
automatically reloaded with the system data backup.
9.3 Other fault indicators
The Mobile Advantage automatic fault handling operations detect and assist
in resolving most faults. Some failures cannot be automatically detected by
User Manual—Mobile Advantage Wireless Office (DWOS 1.0)
52 (80) 198 17-HRC104 201 PA9
the system. To assist in troubleshooting some failures, the CRE boards, RHs,
and Scanners have Light Emitting Diodes (LED). The LEDs, located on the
front of the boards or units for easy observation, provide indications of unit
status. All CRE boards have at least one power LED located at the top of the
board. The power LEDs display green when DC power is supplied to the
board.
The following tables describe specific LED indications of board and unit
statuses.

10 Software and Hardware Upgrades
Upgrading Mobile Advantage to implement new functions, hardware, or units
can require the loading of new software. Mobile Advantage guides the O&M
user when loading software.
Note: Always perform the replacement or upgrading of hardware and
software during periods of light traffic. When upgrading there is
always the possibility the newly installed hardware or software may
not function properly with Mobile Advantage. Be prepared to uninstall
an upgrade if necessary.
10.1 Hardware Upgrades
The installation of new hardware is typically plug and play (P&P). When new
hardware is installed in the CRE, the hardware is automatically detected and
activated. Installing most new CRE boards or replacing defective boards can
be done while the CRE is powered (hot swapping).
In the service area “Hardware Resources”, the user can create, browse, delete,
block, and unblock boards, links, and trunks. The user can also install and
modify software releases.
Note: For the SWB only, deactivate (block) the device before physically
removing it to prevent misleading traps from being generated.
All cables should be attached to CRE boards after installing. For example,
RLU boards should have the cables to the RHs connected after installation.
Installing the boards with the cables connected could cause a large current
surge to the RHs.
When upgrading or replacing an RH, Scanner, and most units, Mobile
Advantage loads new software automatically. The Mobility Server reads the
new configuration data from the CRE and activates the new hardware. RHs
and Scanners require a warm-up period before operating accurately.
The following Mobile Advantage units cannot be replaced with the plug and
play installation method:
•Replacement of the Mobility Server requires reinstallation of Mobile
Advantage software. Replacement of redundant units in the Mobility
Server can be done in the P&P manner with “hot swapping”.
Replacement of boards that are not redundant or capable of “hot
swapping” requires shutting down and powering OFF the Mobility
Server.
•The SWB has a configurable IP interface which must be initialized.
Replacing the SWB requires deleting the defective board and creating a
new board. This requires entering the IP address, along with other data,
of the SWB in the service area “Hardware Resources” selection “Board”.
•The CRE Power Module (CPM) and SYNC boards are not “hot
swappable”. Replacement of the CPM and SYNC boards in the CRE
effects all boards. Turn OFF power to the CRE when replacing the CPM
and SYNC boards.

11.4 RLU Ethernet Interface Cable (Slot Three Only)
The RLU in slot three of the main cabinet, functioning as the CRE central
processor, requires an Ethernet interface to the Mobility Server. A reverse
CAT 5 cable, supplied with the system, connects the RLU in slot three to the
Mobility Server. A reverse CAT 5 cable is designed as a direct link between
Ethernet nodes. With a reverse CAT5 cable the receive (RXD) and transmit
(TXD) wire pairs are swapped. The RLU reverse CAT 5 cable specifications
are shown in Table 8.
Note: The Ericsson CAT 5 cables, supplied with the system, must be used to
comply with radiated emissions regulations. Install the cable
connector end with the exposed shield to the RLU board and the end
with the covered shield to the Mobility Server port.
11.5 RLU Connections
Power and signal connections between the RHs or Scanners and the CRE are
routed through the cabling from RLU boards in slots four, five, seven, and
eight. Cabling consists of two parts; the RLU cables connect from the RLU
boards to the punch blocks and CAT 5 cables connect from the punch blocks
to RHs or Scanners. Two RLU to punch block cables are supplied with the
system for each configured RLU board.
11.5.1 Punch Block to Radio Heads (RH) or Scanners Cabling
The CAT 5 cables going to the punch blocks are supplied by the customer.
Ericsson recommends using any unshielded, 24-AWG, 4-pair, solid
conductor CAT 5 cables. A recommended CAT 5 cable type for this use is
shown in Table 9.
Note: Cables that are routed through ceilings or plenums must be rated for
fire safety. The applicable cable plenum specifications are defined in
NEC CMP and CSA PCC FT4/FT6.

Using the recommended cables allow the RHs or Scanners to be located up to
1600 meters (5280 feet) from the CRE. RHs located less than 800 meters
(2640 feet) from the CRE receive power from the RLU boards through the
CAT 5 cables. For Scanners located up to 1200 meters (3960 feet) from the
CRE, the RLU boards also supply the power through the CAT 5 cables.
RHs and Scanners can be located up to a maximum of 1600 meters from the
CRE if powered from a 24 Vdc converter. The 24 Vdc converters require 115
Vac outlets nearby.
Note: If necessary, other types of twisted pair cable may be used. However,
using lower quality cable will result in shorter distance capabilities.
Use of any cable type except those recommended requires an
evaluation of that link by Ericsson.
Figure 10 is an overview of RLU cabling from a representative RLU board to
RH or Scanners. The central point for connections is the punch block. See

Acronyms and Abbreviations
10BASE-T—10Mbit/s Ethernet system using twisted pair cables. The twisted
pair only supports point-to-point connections. To connect several terminals a
repeater hub is required.
850 MHz—The hyper band that is called cellular today (defined in
TDMA-136.2-A table 2.1.1.1.1-1). The frequency bands at 850 MHz are
named a, a', a'' and b, b'. Normally one cellular operator owns the license to
operate on a-band (including a' and a'') or b-band (including b').
1900 MHz—The hyper band called PCS today (defined in TDMA-136.2-A
table 2.1.1.1.2-1). The frequency bands at 1900 MHz are named A, B, C, D,
E and F. Normally one cellular operator owns the license to operate on one of
these bands.
ACELP—The speech coding algorithm used in Mobile Advantage is defined
as an alternate speech coder algorithm in TDMA-136.2-A 2.1.3.3.2. (The
actual description is in IS-641). The ACELP codec is considered to have a
better speech quality than VSELP. Another name for the ACELP coder is
EFR.
A-key—The input number that the authentication process uses as one of the
input to the Auth_Signature algorithm. See TDMA-136 for details.
Allowed-list—The frequencies that Mobile Advantage is allowed to use. If no
allowed-list is entered Mobile Advantage will consider the whole frequency
band, except the disallowed-list, as being on the allowed-list. Allowed list +
disallowed list = the whole frequency band.
AMPS—Advanced Mobile Phone System. The analog system which operates
on 850 MHz.
ANSI-41: Cellular Radio Telecommunications Intersystem Operations, the
TIA specification of how the VLR, HLR and MSC communicate.
Barred—The user is not allowed to use the system. In the cellular system this
can be used when the user has not paid his bills, but the cellular operator wants
to enable calls as soon as the money arrives. In Mobile Advantage we can use
this to define a user in the cellular HLR to provide for authentication and
voice privacy in Mobile Advantage, but barr him from making calls in the
cellular system.
BOOTP—The Bootstrap Protocol, BOOTP, is a UDP/IP based protocol,
which allows a booting client to configure itself dynamically and without user
supervision. BOOTP provides a means to notify a client of its assigned IP
address, the IP address of the boot Server host, and the name of the file to be
loaded into the memory and executed.

Advantage cables see, "Appendix A—Cabling and Connectors," on page 58.
13.1 Mobility Server
The Mobility Server is based upon a Microsoft Windows NT™ server with
redundant drives, fans and power supplies. A four-port Network Interface
Card (NIC), two serial ports, and an optional internal modem provide external
access and communications. The Mobility Server performs all call control,
service control, and O&M functions in the Mobile Advantage system.
The Mobility Server is powered by redundant -48 Vdc power supplies.
Indications of loss of a single power supply, fan module, or hard drive, and
other failures are propagated to the Mobile Advantage event log and can be
configured to signal audibly.
The temperature range where the CRE and Mobility Server are located must
be between +5°C and +40°C and relative humidity may vary between 15%
and 80%.
13.2 CRE Specifications
Both the main and auxiliary cabinets have the same part numbers. When an
auxiliary cabinet is connected to a main cabinet the slot assignments are
automatically configured. For example, Mobile Advantage recognizes slot
time in the main cabinet is reserved for the DTU board, but slot nine in the
auxiliary cabinet can be used by SPU or RLU boards.
