Chapter 1 - System Description
1.1
Introducing the Voice Gateway
Alvarion's Voice Gateway enables operators and service providers using Alvarion's
Broadband Wireless Access system to provide subscribers with a number of
broadband services transparently. The Voice Gateway enables bundling services
such as telephony (Voice over IP) and high speed Internet to end-users.
IP-telephony services are supported for standard analog phones or G3 fax
machines. The VG-1D1V has a single POTS interface, and the VG-1D2V has two
POTS interfaces. The Voice Gateways are available with either H.323 or SIP
standard, and support both narrow (compressed) and wide band (uncompressed)
speech codecs, silence suppression with comfort noise, line echo cancellation and
regional telephone parameters. Class 5 services such call waiting and 3-party
conference call are also supported.
Up to 3 telephones can be connected in series to each telephone port. Daisy
chaining of Voice Gateways enables the service provider to offer certain end users,
for example small offices, additional telephone numbers.
The Voice Gateway also supports Internet access or any other Ethernet based
services. The unit can be installed behind a router/NAT due to NAT traversal
support allowing signaling as well as voice packets to correctly reach Softswitch or
Gatekeeper for bi-directional call initiations. The Gateway can handle up to 16
simultaneous VLANs, enabling the operator to offer different services to different
end users behind the unit.
These Gateways incorporate the proprietary DRAP (Dynamic Resources Allocation
Protocol) protocol for automatic registration and allocation of resource. DRAP is a
protocol based on IP/UDP between the Gateway and a DRAP server (e.g. the
BreezeMAX base station). The protocol provides an auto-discovery mechanism for
the Gateway, so no specific configuration is required and the Gateway can
automatically locate and register with the DRAP server. The protocol uses a few
simple messages enabling a Voice Gateway to request resources when calls are
made, and the DRAP server to dynamically allocate them.
The Voice Gateways are designed for remote management and supervision using
either the built-in internal web server or SNMP.
The Voice Gateways are easily updated and upgraded as they support remote
software and configuration file download.

Notes on Using the Voice Gateways in
Alvarion's Systems
2.4.1 BreezeMAX System (Version 1.5 and higher)
„ Access the Monitor program of the SU from a PC connected to the LAN port of
the Gateway. The SU's Monitor program uses the fixed IP address
192.168.254.251 with the subnet mask 255.255.255.0. The PC used for
accessing the Monitor program should be configured to belong to the same
subnet. It is recommended to set the PC's IP address to 192.168.254.250,
which is the default TFTP Server IP address in the Monitor (required for
downloading SW versions and for downloading/uploading configuration files).
„ Information about the DRAP-enabled Gateways that are connected to each SU
can be viewed in the Base Station's Monitor program (in the Voice/Networking
Gateways option of the Configuration menu for a selected SU). The displayed
information includes Gateway's type, IP Address, and the VLAN ID used for
management.
„ In general, the same VLAN should be configured in the Voice Gateway for
Management (Default VLAN ID) and Voice (RTP and Signaling) as the Voice
Gateway uses one IP address for two VLANs and the default router in the
backbone cannot operate in this mode.
„ To support the required quality of service when DRAP is used, provision the
correct VoIP Service. If DRAP is not used, provision an L2 Service with a CG
connection (refer to the BreezeMAX System Manual for details).
2.4.2 BreezeACCESS VL System (Version 3.1)
„ To access the Monitor program of the SU from a PC connected to the LAN port
of the Gateway, the WAN port must be configured with static IP address that is
in the same subnet as the IP Address of the SU, and subnet mask
255.255.255.0 (the default IP address is 10.0.0.1 with a Subnet Mask
255.255.255.0). The PC used for accessing the Monitor program should be
configured to belong to the same subnet.
„ Configure the Traffic Prioritization parameters in both the SU and the AU to
ensure high priority for RTP traffic. Refer to the BreezeACCESS VL System
Manual for details.

The VoIP VLAN configuration page enables defining the following parameters:
Table 3-5: VoIP VLAN Configuration Page Parameters
Description
Parameter
Call Signaling
VLAN Tag
The VLAN ID tag for VoIP call signaling packets. If not set, the
Default VLAN ID set for WAN (in the VLAN Tagging page) will
also apply for VOIP.
Priority Tag
The Priority tag for VoIP call signaling packets. If not set, the
priority tag defined for the Management VLAN in the Tagged Port
Membership (in the VLAN Tagging page), will also apply for
VOIP.
RTP
VLAN Tag
The VLAN ID tag for RTP and RTCP packets. If not set, the
Default VLAN ID set for WAN (in the VLAN Tagging page) will
also apply for VOIP.
Priority Tag
The Priority tag for RTP and RTCP packets. If not set, the priority
tag defined for the Management VLAN in the Tagged Port
Membership (in the VLAN Tagging page), will also apply for
VOIP.
Typically, the same VLAN is used for management, call signaling and RTP. In this
case, the same VLAN and Priority Tags should be configured for management
(Default VLAN on WAN port in the VLAN Tagging page), Call Signaling and RTP.
However, the Voice Gateway supports separation of VLANs and allows defining 3
different VLANs for management, call signaling and RTP traffic (this may require a
proper router). Different Priority tags for management, call signaling and RTP can
be configured. The Priority tag for management is defined in the Priority field of
the management VLAN ID (configured in the Tagged Port Membership table).

The Dialplan parameter defines how the Voice Gateway decides
that a complete number has been dialed. See more details in
The default value is xx.T|xx.#, which means that each of the
following schemes can be used:
„ xx.T: Dial timeout. Any number of digits may be dialed.
Following T seconds in which no new digit is dialed, a decision
is reached that dialing was completed and the unit will send the
dialing sequence received up to this time as a complete
telephone number. This is necessary since the whole telephone
number is sent at once and not digit by digit.
„ xx.#: Any number of digits may be dialed. A decision that dialing
was completed will be reached once # is pressed.
The combination of both schemes means that dialing is completed
either after a timeout of T seconds or after pressing #.
Dial timeout
The timeout in seconds for the dial timeout dialplan. The number of
seconds that the unit waits before it sends a complete telephone
number. This is necessary since the whole telephone number is
sent at once and not digit by digit.
The range is 1 to 60 seconds
Default value is 4 seconds.

The jitter buffer options are common to both lines (if applicable):
Table 3-7: Jitter Buffer Options
Description
Parameter
Adaptive Jitter Buffer Maximum
Delay
The Voice Gateway uses a Jitter Buffer to eliminate jitter
effects. The size of the buffer changes dynamically to reflect
actual jitter conditions. The Adaptive Jitter Buffer Maximum
Delay defines the maximum size that is available for the jitter
buffer (the larger the size, the greater the potential delay).
The range is from 100 to 300 milliseconds.
The default duration is 100 milliseconds.
Fixed Jitter Buffer
When using fax only, it is recommended to use a fixed jitter
buffer. The fixed jitter buffer may affect voice conversation
performance.
The range is from 100 to 300 milliseconds.
The default duration is 40 milliseconds.
Automatically switch to Fixed Jitter
Buffer
Select this option in order to use both fax and voice. The Voice
Gateway automatically switches to the configured Fixed Jitter
Buffer upon detecting a fax/modem tone.

Description
Parameter
SS
The SS (Silent Suppression) option for outgoing calls. When the
SS option is enabled, silence intervals are identified and only
relevant information is transmitted, using less bandwidth than
during voice activity intervals. This allows for a better overall
utilization of the available bandwidth. It is possible to enable
Silent Suppression with G729 codec. Silent Suppression is not
applicable when using the G711 codecs.
The default (G729) is SS disabled.

The range is from 10 to 150 milliseconds.
The default is 30 ms for G729 and 20 ms for G711A and G711U.
Keypad
The "Keypad" field indicated which transmission method to be
used for user input DTMF signaling (i.e. phone banking). "None"
means in-band, which should be used with G.711 only.
For SIP model the options are None, RFC2833 and SIP INFO.
RFC2833 and SIP INFO should be used primarily with G.729
but could also be used with G.711. The default is None for G711
codecs and RFC2833 for G729.
For H323 model the options are H225, H245, RFC2833 and
None. The default is None for G711 codecs and H225 for G729.
Priority
The Priority parameter defines the relative priorities to be offered
during capabilities' exchange. If only G711A and G711U are
used, the permitted priorities are 1 and 2.
If all 3 codecs are used, the permitted priorities are 1, 2 and 3.
Voice codec negotiation/priority is always performed between 2
end-points and depending on which side initiated the
negotiation.
The default is Priority 1 to G711A, Priority 2 to G711U.

header value
If the called user agents (UA) or the SIP Proxy Server (SPS) requires a
session timer for a requested session and the calling UA does not include
the Session-Expires header in the INVITE message, then the called UA or
the SPS may reject the request with a 487-request failure message. If the
use of a session timer is desirable but optional for the session and the
calling UA does not include the Session-Expires header in the INVITE then
the called UA or SPS may add a Session-Expires header to the next
session setup message. In this case, the SPS shall add the
Session-Expires header to the INVITE message and the called UA shall
add the Session-Expires header to the 200 OK response message. The
range for the timer header value is from 1 to 999.
SIP Session timer value
The SIP Session Timer Support feature adds the capability to periodically
refresh Session Initiation Protocol (SIP) sessions by sending repeated
INVITE requests. The repeated INVITE requests, or re-INVITEs, are sent
during an active call leg to allow user agents (UA) or proxies to determine
the status of a SIP session. Without this keep alive mechanism, proxies
that remember incoming and outgoing requests (stateful proxies) may
continue to retain call state needlessly. If a UA fails to send a BYE
message at the end of a session or if the BYE message is lost because of
network problems, a stateful proxy does not know that the session has
ended. The re-INVITES ensure that active sessions stay active and
completed sessions are terminated. The range for the timer value is from 1
to 999 seconds.
Use NOTIFY message to The gateway will send a SIP NOTIFY message to the SIP proxy at the
keep alive the session
with SIP proxy every X
seconds
configured interval. These messages can keep the connection with SIP
proxy alive, as well as the NAT port mapping when the Voice Gateway is
behind NAT.
The range is: 0-99999
Default interval: 15 seconds

3.7.4 STUN Client Configuration Page (SIP only)
Simple Traversal of UDP (STUN) is a method of NAT traversal through UDP, based
on RFC 3489. For proper voice conversations in networks based on more than one
NAT, the NAT devices must be able to transfer RTP packets in both directions.
The STUN protocol uses the default server port 3478. The Voice Gateway
communicates with a server over the internet. Based on the RTP packets, the
Server knows the number of NATs behind which the Voice Gateway is located, the
IP address of the Voice Gateway, and which of the Voice Gateway's ports are
actually used.
The STUN application supports the following NAT Types: FullCone, FullRestrict,
and PortRestrict. The Voice Gateway does not support symmetrical NAT as it is
not meant to traverse symmetrical NAT devices.

3.7.7 Dial Plan Schemes
A dialplan gives the unit a map to determine when a complete number has been
entered and should be passed to the gatekeeper/SIP server for resolution into an
IP address. Dialplans are expressed using the same syntax as used by MGCP NCS
specification. The following notation describes the formal syntax of the dialplan:
Digit ::= "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
Timer ::= "T" | "t"
Letter ::= Digit | Timer | "#" | "*" | "A" | "a" | "B" | "b" | "C" | "c" | "D" | "d"
Range ::= "X" | "x" -- matches any digit
| "[" Letters "]" -- matches any of the specified letters
Letters::= Subrange | Subrange Letters
Subrange::= Letter -- matches the specified letter
| Digit "-" Digit -- matches any digit between first and last
Position::= Letter | Range
StringElement::= Position -- matches any occurrence of the position
| Position "." -- matches an arbitrary number of occurrences including 0
String ::= StringElement | StringElement String
54
Operation
Download from Www.Somanuals.com. All Manuals Search And Download.
Telephone Menu
StringList::= String | String "|" StringList
DialPlan::= String | "(" StringList ")"
[0-9] denotes a single digit between 0 and 9. To configure a range of more than 10
numbers (e.g., 800xxx-819xxx) use the scheme: 80xxxx|81[0-9]xxx.
A dialplan, according to this syntax, is defined either by a (case insensitive) string
or by a list of strings. Regardless of the above syntax a timer is only allowed if it
appears in the last position in a string (12T3 is not valid). Each string is an
alternate numbering scheme. The unit will process the dialplan by comparing the
current dial string against the dialplan. If the result is under-qualified (partial
matches at least one entry) then it will do nothing further but wait until a full
match is reached. If the result is over-qualified (no further digits could possibly
produce a match) then it aborts the dial attempt and notifies end-user with an
audio signal. Only a full match will trigger to initiate a call, by sending the dialed
information to a Gatekeeper/SIP server.
The Timer T is activated when it is all that is required to produce a match. The
period of timer T is 4 seconds as default (configurable). For example a dialplan of
(xxxT|xxxxx) will match immediately if any 5 digits are entered. It will also match
following a 4 second pause after entering 3 digits.
IMPORTANT
The dialplan is according to section 2.1.5 of RFC 3435.
The “.” notation, denotes zero or more keys. That is, x.# means none or at least one digit followed
by # and x.T means none or at least one digit followed by T.
However, having only T in the dialplan (where x is null) activates the Hotline function (see
xx.#|xx.T.
Simple dialplan (Example 1):
Following example allows dialing any 7-digit number (e.g. 5551234) or an operator
on 0.
Dialplan is: (0T|xxxxxxx)
Complex dialplan (Example 2):
Local operator on 0, long distance operator on 00, four digit local extension
number starting with 3,4 or 5, seven digit local numbers are prefixed by an 8, two
digit star services (e.g. 69), ten digit long distance prefixed by 91, and
international numbers starting with 9011+one or more digits.
Dialplan for this is: (0T|00T|[3-5]xxx|8xxxxxxx|*xx|91xxxxxxxxxx|9011xx.T)

Chapter 3 - Using the Web Configuration Server
Using supplemental external services (Example 3):
When a soft switch or a SIP server/gatekeeper exists in the network and the user
would like to use class 5 services which are not internal to the Voice Gateway e.g.,
*xy#, *xy*abcd#, #xy#, etc., the VG dialplan should be configured as follows:
[*#][0-9*][0-9*].#
Note that when VG internal class 5 services are enabled (default) in addition to the
Call completion
Call completion means allowing user to skip the timer period T after finished
dialing, by ending number sequence with '#' (no other character is valid for this
feature). A valid dialplan to accomplish this would be: (xx.#|xx.T)
3.7.7.1
Hotline
The hotline function allows a predetermined number to be called automatically by
waiting T seconds (which can also be configured) without pressing any keys.
The hotline function can also be used to receive tones from the Local Exchange.
This is achieved by leaving the number in the hotline dialplan empty. Additional
modifications may be required, in which case, contact Customer Support for
assistance.
The hotline feature is activated by specifying "T" (time-out) in the dialplan (by
default, T is set to 4 seconds).
For example: (xx.#|xx.T|<:1234>T)
The number 1234 will be dialed after T seconds.
3.7.7.2
Adding/Removing Prefixes
For outgoing calls
VG can add a pre-defined prefix to a dialed number via the dialplan and send the
number with the added prefix to the server. The prefix can automatically replace a
dialed digit using the following notation:
"<'dialed substring':'transmitted-string'>"
For example:
Set the dialplan to "<8:1860>xxx"
When dialing 8123, the digit 8 is replaced with 1860, and the actual number sent
is 1860123.
56
Operation
Download from Www.Somanuals.com. All Manuals Search And Download.
Telephone Menu
In ethereal trace, the "To" field in SIP INVITE is "1860123"
For incoming calls
VG can remove a prefix in the dialplan and show the number without the prefix on
the phone display. Use the following notation:
"<'replacement string':'received-string'>"
For example:
Set the dialplan to "<8:1860>xxx"
When a number with the 1860 prefix is received (e.g., "1860123"), the prefix 1860
is replaced with the digit 8 and the number displayed is 8123.

The version R2H implementation of the dialplan module is fully compliant with
RFC3435. However, some previously acceptable dialplans are inconsistent with
RFC3435 operation and must therefore be changed to ensure continued operation
consistent with previous releases. You should review your dialplan to ensure that
the dial behavior will continue to be that required by your customers.
For example, the default dialplan should be changed from (x.#|x.T) to (xx.#|xx.T).
It is recommended to review your dialplan to ensure that its proper operation.
You can change the dialplan as follows:
„ Default dialplan

Appendix C - New Features
In This Appendix:
This appendix explains the new features and parameters configurable in the ini
files. The ini files are generated and encrypted by Alvarion upon request. For a
complete list of parameters refer to “SIP VG INI Parameters - Customer
Questionnaire”.
Download from Www.Somanuals.com. All Manuals Search And Download.
Appendix C - New Features
C.1 Metering Support
The VG can generate metering pulses, reverse polarity and pulse metering.
The metering pulse are generated in terms of the indication from head
V5-Signal-Info in INFO message.
The customer is required to select the pulse metering or the reverse polarity
parameters. If pulse metering is selected, the frequency (12KHz or 16KHz), the
pulse level duration and the interval parameters are also required.
Default values are:
„ Pulse Frequency: 12Khz.
„ Pulse Level: 200.
„ Pulse Duration: 150.
„ Pulse Interval: 1000.
C.2 Sending VoIP Performance Data to a
Remote System
The performance data of each call can be sent out to a specified syslog server after
the call ends if the syslog address [and port] is configured. The data content is the
same as what present on RTP stat page. The message format strictly complies
with the standard syslog protocol.
The syslog server IP and port are defined in the VG INI file.

Customized Ring Signals
C.3 Customized Ring Signals
The called VG can play customized ring signal specified in the Alert-Info header
instead of playing local configured ring signal.
The VG supports up to 10 different ring signal, that can be edited in the Ini file.
C.4 Spanning Tree Working Mode
Configuration
The Spanning tree working mode on VG11/22 can be configured as one of the
following:
„ OFF: DRG does not send STP packets out and the port goes into forwarding
state directly whenever an interface is active. This is the default working mode.
„ FAST: DRG sends STP packets out and the port goes into forwarding state
directly whenever an interface is active.
„ ON: DRG sends STP packets out and the port stays in listening state whenever
an interface is active. The port state is then transferred as per what
IEEE802.1D describes.
The spanning tree mode is configured in the Ini file.
C.5 Ring Signal Frequency and Amplitude
Configuration
Ring signal frequency and amplitude can be configured, as follows:
„ Ring signal frequency: 16,20,25,50Hz.
„ Ring amplitude: 15-94 in Vpk.
The ring signal and frequency are configured in the Ini file.

Telecommunications. An intergovernmental organization
through which public and private organizations develop
telecommunications. The ITU was founded in 1865 and
became a United Nations agency in 1947. It is responsible for
adopting international treaties, regulations and standards
governing telecommunications. The standardization functions
were formerly performed by a group within the ITU called
CCITT, but after a 1992 reorganization the CCITT no longer

MDI/MDIX
MDI/MDIX is a type of Ethernet port connection using twisted
pair cabling. The MDI (for Medium Dependent Interface) is the
component that provides the physical and electrical connection
to the cabling medium. An MDIX (for MDI crossover) is a
version of MDI that enables connection between like devices.
MDI ports connect to MDIX ports via straight-through twisted
pair cabling; both MDI-to-MDI and MDIX-to-MDIX connections
use crossover twisted pair cabling. The design of Auto
MDI/MDIX or Auto Crossover is used to automatically identify
the cable type and internally switch over the TX/RX paired
signals.
MIB
NAT
Management Information Base. A database of objects that can
be monitored by a network management system. SNMP uses
standardized MIB formats that allow any SNMP tools to
monitor any device defined by a MIB.
Network Address Translation: An IETF standard that allows an
organization to present itself to the Internet with far fewer IP
addresses than there are nodes on its internal network. The
NAT technology, which is typically implemented in a router,
converts private IP addresses (such as in the 192.168.0.0
range) of the machine on the internal private network to one or
more public IP addresses for the Internet. It changes the
packet headers to the new address and keeps track of each
session. When packets come back from the Internet, NAT
performs the reverse conversion to the IP address of the client
machine.
NTP
Network Time Protocol: A protocol used to update the real time
clock in a computer. There are numerous primary and
secondary servers in the Internet that are synchronized to the
Coordinated Universal Time (UTC) via radio, satellite or

PPPoE
Point-to-Point Protocol over Ethernet. PPPoE relies on two
widely accepted standards: PPP and Ethernet. PPPoE is a
specification for connecting the users on an Ethernet to the
Internet through a common broadband medium, such as a
single DSL line, wireless device or cable modem. All the users
over the Ethernet share a common connection, so the Ethernet
principles supporting multiple users in a LAN combines with
the principles of PPP, which apply to serial connections.
REN
Ringer Equivalency Number: A number determined in
accordance with the Code of Federal Regulations, Title 47, part
68, which number represents the ringer loading effect on a
line. A REN of 1 represents the loading effect of a single
traditional telephone set ringing circuit. Modern telephone
instruments may have a REN lower than 1.

RTCP
RTP
RTP Control Protocol. A protocol that monitors the QoS of an
RTP connection and conveys information about the on-going
session.
Real Time Protocol. An Internet protocol for transmitting
real-time data such as audio and video. RTP itself does not
guarantee real-time delivery of data, but it does provide
mechanisms for the sending and receiving applications to
support streaming data. Typically, RTP runs on top of the UDP
protocol, although the specification is general enough to
support other transport protocols.
SIP
Session Initiation Protocol. An application-layer control IETF
protocol that can establish, modify, and terminate multimedia
sessions such as Internet telephony calls (VoIP). SIP can also
invite participants to already existing sessions, such as
multicast conferences. Media can be added to (and removed
from) an existing session. SIP transparently supports name
mapping and redirection services, which supports personal
mobility - users can maintain a single externally visible
identifier regardless of their network location.

V.17
An ITU fax standard (1991) that uses TCM (Trellis-Coded
Modulation, a technique for forward error correction)
modulation at 12,000 and 14,400 bps for Group 3 faxes. It
adds TCM to the V.29 standard at 7,200 and 9,600 bps to
allow transmission over noisier lines. It also defines special
functions (echo protection, turn-off sequences, etc.) for
half-duplex operation. Modulation use is a half-duplex version
of V.32bis.

4,800, 7,200, 9,600, 12,000 and 14,400 bps full-duplex
modems using TCM and echo cancellation. It supports rate
renegotiation, which allows modems to change speeds as
required.
Virtual Local Area Network. A group of devices on one or more
LANs that are configured with the same VLAN ID so that they
can communicate as if they were attached to the same wire,
when in fact they are located on a number of different LAN
segments. Used also to create separation between different
user groups.
