PRODUCTS
Aethra Gateway version 5.0, consists of the following products:
ABOUT THE
AETHRA P20
The Aethra P20 Gateway enables audio, video, and data communication
between H.320 endpoints that connect through ISDN, and H.323 endpoints that
connect through a packet-based network. For voice-over-IP, the gateway enables
PSTN voice callers to connect from the ISDN network to IP voice callers. The
Aethra P20 supports two PRI ISDN ports.
ABOUT THE
AETHRA B40
The Aethra B40 Gateway enables audio, video and data communication
between H.320 endpoints that connect through Integrated Services Digital
Network (ISDN), and H.323 endpoints that connect through a packet-based
network. For voice-over-IP, the gateway enables Public Switched Telephone
Network (PSTN) voice callers to connect with IP voice callers. The Aethra B40
Gateway supports up to four BRI ISDN ports.

About Gateway Features
ABOUT GATEWAY
FEATURES
Table 1-1 lists the major features of the Aethra Gateways.
Table 1-1

Aethra Gateway User Guide
Gateway Feature Summary
Feature
Description
Interoperability
The Gateway provides a high degree of interoperability
with other H.323 compliant gateways, gatekeepers,
terminals, proxy, and Multipoint Control Unit (MCU)
products by being based on the H.320 standard and
H.323 protocol stack.
Web-based management
The Gateway features the Gateway interface. This is a
web interface used to configure and monitor the
Gateway. You can view and modify all aspects of the
Gateway configuration from a remote location using a
Java-enabled web browser.
SNMP management
The Gateway features Simple Network Management
Protocol (SNMP) management that supports all aspects
of monitoring, diagnostics, configuration, and trapping.
Diagnostics
The Gateway features front and rear panel LED
indicators that display status for the unit. You can also
access remote diagnostics of the unit through the
Gateway interface, Telnet, SNMP, or a serial port.
Network load balancing
The Gateway supports load balancing on the network by
communicating with a gatekeeper through H.323 RAI
(Resource Available Indication)/RAC (Resource
Available Confirmation) messages.
T.120 data collaboration
The Gateway supports data transfers in calls between
ISDN and IP by using high speed T.120 in HMLP and
VarMLP formats.
Quality of service (QoS)
The Gateway features configurable coding of media
packets to achieve QoS routing priority on the Internet
Protocol (IP) network. The Type of Service (ToS) bits of
the IP datagram header can be configured for priority
level.
About Gateway Features
Table 1-1
Gateway Feature Summary (continued)
Feature
Description
Dial plan
The Gateway supports a simplified dial plan for
outbound dialing using a single universal prefix. Using
the dial plan, the Gateway automatically detects the
capabilities received in the Setup message from the IP
endpoint and sets the same bit rate for the ISDN (or serial
interface) side of the call.
Direct dialing and call routing The Gateway dial plan supports the following direct
dialing and call routing facilities:
Direct Inward Dialing (DID)
Multiple Subscriber
Network (MSN)
Q.931 Sub-addressing
Information Element
Internal and External Interactive Voice
Response (IVR)
TCS4
Default extension
Access control
The Gateway features password-controlled access to the
Gateway interface. Up to ten different administrator
access profiles can be defined for the Gateway.
DTMF translation
The Gateway supports translation between in-band Dual
Tone Multi-Frequency (DTMF) signals (on the ISDN
side) and out-of-band H.245 messages (on the IP side).
DTMF translation occurs for voice and video calls.
Dual video
The Gateway supports dual video streams for a single
call using TANDBERG Duo Video™ technology. Dual
video streams enable a screen to carry video images from
one source while simultaneously displaying images from
a second source.
Conceal caller ID
The Gateway supports a conceal caller ID feature that
instructs the gatekeeper to conceal the identity of the
calling endpoint on the IP or ISDN network, whether the
presentation restricted feature is enabled or not.

Aethra Gateway User Guide
Gateway Feature Summary (continued)
Feature
Description
H.323 fast start
The Gateway H.323 fast start feature enables endpoints
to join a voice conference in the Gateway more quickly.
ISDN rollover (available in
Aethra P20 only)
The Gateway features ISDN rollover. In this feature, the
Gateway sends a “busy out” channel request to the PSTN
switch when the current PRI connection is left with less
than a predefined number of available B channels. The
PSTN switch “rolls over” to the next available gateway.
Network Specific Facility
(available in Aethra P20
only)
The Gateway provides support for Network Specific
Facility Information Elements (NSF IEs) which enable
system administrators to specify to service providers the
equipment, service, or network through which they want
a call routed.
ISDN connection failure
The Gateway responds to ISDN connection failure
events, by unregistering from its gatekeeper. The
gatekeeper is forced to send new IP-to-ISDN calls
through a different gateway, thus ensuring high call
completion rates. The Gateway re-registers to the
gatekeeper when the ISDN connection is restored.
Downspeeding
The Gateway features downspeeding functionality. In the
downspeeding feature, the Gateway attempts to
reconnect a disconnected video call either at a lower
bandwidth or as a voice call. Downspeeding contributes
to a higher percentage of call completion on the network.
The Gateway supports downspeeding at call setup and in
mid-call.
Multiple trap server support
The Gateway supports up to three SNMP trap servers.
H.239 support
The Gateway supports the H.239 protocol in ISDN-to-IP
calls and in IP-to-ISDN calls.
H.235 encryption for H.323
calls
The Gateway supports H.325-compliant encryption for
calls over IP networks.
About Gateway Features
Table 1-1
Gateway Feature Summary (continued)
Feature
Description
H.243 Conference Control
support
The Gateway supports the H.243 protocol in ISDN-to-IP
calls and in IP-to-ISDN calls. The Gateway identifies the
protocol version that an IP endpoint uses and sends
H.239 capabilities only to those endpoints working with
protocol version 4.0 or later.
Peer-to-peer connectivity
The Gateway supports connectivity to the IP network
through a gatekeeper, or directly to a peer device such as
Cisco Unified CallManager.
IP network connections
The Gateway has one 10/100Base-T Ethernet IP port (on
the front panel) and connects to an IP segment through a
direct connection to a network switch.

terminal
Together with the Aethra MCU, the Aethra PRI gateway and BRI Gateway
enable H.320 ISDN terminals to participate in a mixed ISDN-IP multipoint
multimedia conference with IP network endpoints (see Figure 1-3).
For example, when an H.320 ISDN terminal wants to participate in a multipoint
conference with H.323 IP endpoints, the H.320 ISDN terminal can either join
the multipoint conference by dialing to the Gateway, or be invited into the
conference by one of the participating IP endpoints. In either case, the Gateway
connects the ISDN terminal to the Aethra MCU, enabling it to participate in the
multipoint conference.

64 Kbps
According to the H.320 standard, the available bandwidth allocated to a call at
any given bit rate will always be slightly less than the stated maximum for the
following reasons:
All stated maximum call bandwidths include provision for control,
audio, video, and data traffic.
Video traffic on the ISDN side contains additional bits for error
correction purposes which also consume bandwidth. Video traffic on
the IP side does not include this additional load.
Opening an audio channel further reduces the bandwidth available to
the video traffic.
For example, a call at 384 Kbps actually has only 363 Kbps available to it.
Control and error correction account for the remaining 21 Kbps.
RESOURCE
ALLOCATION ACROSS
E1/T1 LINES
The Gateway can allocate bandwidth resources to calls across separate E1 or T1
connections to maximize bandwidth capacity in cases where there is not enough
capacity for a call on a single E1 or T1 connection, but where sufficient capacity
does exist when remaining capacity on both E1/T1 lines is combined.
For example, a Gateway using two T1 lines can support three 6B calls on each
T1 line, with 320 Kbps spare capacity per line:
Each T1 line provides 23 B channels.
Each B channel supports 64 Kbps
Each T1 line supports 23 x 64 = 1472 Kbps
Each 6B call requires 6 x 64 = 384 Kbps
Each T1 line supports 1472/384 = 3 6B calls + 320 Kbps spare
Functionality
15
About Aethra Gateway Functionality
The Gateway processes an additional 6B call requiring a further 384 Kbps by
taking bandwidth resources from each of the two T1 lines, both of which have
320 Kbps available. In this way, the Gateway spreads the call over both T1 lines.

10 (PRI gateways only) Select the Unregister from Gatekeeper
on ISDN connection failure check box to force the Gateway
to unregister from its gatekeeper when both ISDN D-channel
connections are no longer active. The gatekeeper is forced to
send new IP-to-ISDN calls through a different Gateway, thus
ensuring high call completion rates. The Gateway re-registers
to the gatekeeper when the ISDN connected is restored.
11 Select the Send load balancing messages (RAI) check box to
enable the sending of RAI messages to the gatekeeper for the
purpose of load balancing on the network. If you select this

Gatekeepers can perform load balancing on the network using
feedback from the Gateway in the form of Resource Available
Indication (RAI) messages that inform the gatekeeper of
Configuring the Aethra Gateway
49
Configuring Gateway Settings
Gateway resource availability. If the Gateway is unavailable,
the gatekeeper performs line hunting operations to route the call
to an alternative gateway.
When you set the Gateway for RAI/RAC, it sends periodic RAI
messages that inform the gatekeeper of the current resource
availability in the Gateway. The gatekeeper responds with
Resource Available Confirmation (RAC) messages to
acknowledge receipt of the RAI messages. In step 12 and step
13, you can configure the upper and lower threshold for
triggering RAI messages according to resource availability in
the Gateway.
12 In the Send ‘busy’ when load is more than field, enter the
upper threshold for Gateway resource utilization as a
percentage of total resources. When resource use is greater
than the threshold, the Gateway sends the gatekeeper a ‘busy’
RAI message, indicating to the gatekeeper that it should stop
routing calls to this Gateway.
13 In the Send ‘free’ when load is more than field, enter the
lower threshold for Gateway resource utilization as a
percentage of total resources. When resource use is less than
the threshold, the Gateway sends the gatekeeper a ‘free’ RAI
message, indicating to the gatekeeper that it can resume
routing calls to this Gateway.

Note Changing this setting causes the Gateway to reset.
5
In the Peer hunting mode field, choose one of the following
options:
Always start from first peer—The Gateway attempts
to connect a call to the first peer device on the Peer list
section. If the call fails due to one of the H.323 call
disconnect reasons (see About Peer-to-Peer H.323
Call Disconnect Reasons on page 54), the Gateway
tries each peer device in the Peer list section in order
until the call is successfully connected. If the Gateway
fails to connect the call after trying all the peer devices
on the list, it rejects the call.
Always start from last successful peer—The
Gateway attempts to connect a call to the last peer
device in the Peer list section with which a call was
successfully established. An arrow in the Peer list
section indicates with which of the peer devices a call
was last connected successfully. If the call fails due to
one of the H.323 call disconnect reasons (see About
Peer-to-Peer H.323 Call Disconnect Reasons on
page 54), the Gateway tries each peer device in the
Peer list section in order until the call is successfully
connected. The arrow moves to the peer device with
which the call connection is successful. If the Gateway
fails to connect the call after trying all the peer devices
on the list, it rejects the call and the arrow indicates
with which peer device a call was last connected
successfully. This is the default setting.

Round Robin—As for the Always start from last
successful peer setting, except that the arrow
advances to the next peer device in the Peer list
section even if the call connection succeeds.
Note The peer hunting process starts when any of the following events
occur: the Gateway fails to establish a Transmission Control Protocol (TCP)
connection to the specified peer device after a timeout; the Gateway receives
a “Release Complete” message from a peer device with a “No Resources” call
rejection reason, or one of the other reasons that the Peer-to-Peer disconnect
reason add advanced command specifies; or the Gateway establishes a TCP
connection to the specified peer device, but does not receive a valid H.323
message from the peer device after a timeout.

In the Peer list section, you can configure peer devices
currently configured to work with the Gateway. The Peer list
section displays all configured peer devices in a table with the
following columns:
Peer #—The sequential number of the peer in the list.
Description—The description of the peer device.
IP Address—The peer IP address.
IP Port—The peer IP port number.

To change the order of peer devices used in peer hunting, select
a peer device and click the up or down arrow button to change
its order.
To add or edit a peer device, click Add or select the peer device
and click Edit. Perform the following steps in the Add peer or

Note You cannot add a single peer to the Peer list section more than once.
To delete a peer device, select the peer device and click Delete.
Deleting a peer does not cause its active calls to disconnect, but
no new calls are routed to the deleted peer.
Note The peer hunting process stops when one of the peer devices accepts
the call or when the call is rejected with a disconnect reason. When a Gateway
has scanned the Peer list section and still cannot connect a call, the following
rules apply: if at least one of the peers rejected the call due to capacity
overload, the call rejection reason (towards the call originator) is “No
Resources”; in all other cases, the call rejection reason is “Unreachable
Destination.”

ABOUT
ENCODING/DECODING
PROTOCOLS
A number of video conferencing terminal applications require the G.722 and
G.722.1 audio compression codecs to provide high quality voice
communications. The G.722 and G.722.1 formats, using a digital sampling rate
of 7 KHz, provide higher quality voice sampling with a greater dynamic range.
The Gateway does not transcode G.722 or G.722.1, but supports them
transparently. Since the G.722 codec is of a much higher audio quality than other
codecs and requires higher bandwidths, the Gateway supports G.722 and
G.722.1 at the following call bit rates:
G.722 is supported in calls at 224, 256, 336, 384, 448, 512 Kbps (all
Gateways) and 768, 1472 and 1920 Kbps (PRI gateways only).
G.722.1 is supported in calls at 64, 2B, and 128 Kbps.
Both endpoints in a call must support G.722 and G.722.1 audio codecs.
ABOUT AUDIO
TRANSCODING
The Aethra P20 supports audio transcoding through the Audio Transcoder
Module (TCM). Other Aethra Gateways support audio transcoding through
on-board Digital Signal Processing (DSP).
The TCM is a PCI mezzanine card (PMC) that implements Digital Signal
Processing (DSP). The TCM has a processing capacity of up to 20 channels for
audio transcoding in video calls.
The Gateway TCM can perform audio transcoding between the following types
of audio protocols:
G.711 (ISDN) to G.723.1 (IP)
G.723.1 (IP) to G.711 (ISDN)
Configuring the Aethra Gateway
57
Configuring Gateway Settings
G.728 (ISDN) to G.711 (IP)
G.711 (IP) to G.728 (ISDN)
Note When your unit includes both a Gateway and MCU, G.728 transcoding is
supported on the MCU only.
Each audio codec differs in the audio quality, compression, and bit rates that it
provides. The G.711 codec provides toll quality audio at 64 Kbps, the G.728
codec provides near toll quality audio at 16 Kbps, and the G.723.1 codec
provides voice quality audio at 5.3 or 6.4 Kbps.
Endpoints on the ISDN network usually support the G.711 and G.728 codecs.
Endpoints on IP networks support G.711 and G.723.1 codecs. By performing
transcoding between these audio protocols, the Gateway can support
communication between endpoints with codecs that are incompatible with each
other.
Audio transcoding can also optimize the audio bandwidth usage either on the IP
network (G.723.1 < > G.711) or on the ISDN network (G.728 < > G.711).
Transcoding is particularly useful for ISDN codecs, where bandwidth can be
limited to 128 Kbps for a video call. For example, when transcoding between
G.728 and G.711 takes place, the audio bandwidth usage is compressed to 16
Kbps. This provides an additional 40 Kbps of bandwidth to the existing video
bit rate on the ISDN network, contributing to improved video quality.
Note The Gateway automatically performs A-Law G.711-to-µ-Law G.711
translation between the IP and ISDN sides if needed.
You can configure the Gateway to prioritize the transcoding, giving preference
to a particular codec that is applied to calls, thus optimizing the resource
allocation utilized by each call.
ABOUT T.120 DATA
COLLABORATION
SUPPORT
58
Aethra Gateway User Guide
The Gateway provides full end-to-end support for T.120 data collaboration
sessions, provided all terminals support the T.120 standard in their conferencing
applications. In video calls with data transfer, the Gateway accepts whatever
bandwidth the ISDN connection defines for the data and dynamically adjusts the
outgoing bandwidth used for data by using the MLP, HMLP and VarMLP
formats.
Configuring Gateway Settings
If transcoding or T.120 capabilities are required, the Gateway has to reserve
resources for these. The Gateway can differentiate between those calls that
support T.120 and those that do not. When receiving calls, the Gateway can
check whether you are reserving resources for transcoding or for T.120
capabilities.
The Gateway enables the user to determine the trade-off between the number of
non-T.120 calls that the Gateway can support and the number of calls sent with
T.120 capabilities. The total number of calls that the Gateway can support is
accordingly reduced by this reallocation of resources.
The H.320 standard defines space allocation within a call. The H.320 standard
defines the logic for bit rate allocation among audio, video and data channels in
the context of the overall bit rate of a call. If you work with T.120, reallocation
of bandwidth is always at the expense of available video resources. The
requirements of the H.320 standard govern this reallocation—it is not
configured in the Gateway. The Gateway simply decides whether or not to send
T.120 capabilities. You configure T.120 capabilities in the Advanced section of
the Gateway interface Settings tab.

In the Bonding section of the Settings tab, you can configure ISDN channel
bonding parameters that affect downspeeding functionality.
Downspeeding is the ability to complete and maintain a call when ISDN
conditions are bad. In downspeeding, call capabilities are automatically
renegotiated when a call fails. Downspeeding contributes to a higher percentage
of call completion on the network. The Gateway supports downspeeding at call
setup and in mid-call.
With downspeeding, when connection problems occur at call setup, the Gateway
attempts to connect a call at a lower bit rate than that requested. Administrators
can configure the Gateway to attempt to connect a video call at a specified
minimum bit rate, or to attempt to connect the call as a voice call.
In downspeeding, when connection problems occur in mid-call, the Gateway
attempts to connect a video call at the specified lower bit rate. When
downspeeding is complete and the call is connected at the specified lower bit
rate, the Gateway notifies the Internet Protocol (IP) endpoint of the new call
rate.

CONFIGURING QUALITY
OF SERVICE SETTINGS
You can configure the Gateway to add a Quality of Service (QoS) IP precedence
code in the IP header of outbound packets on the IP network. Routers on the
network that support this method can give precedence to such coded packets and
facilitate the transmission of the packets more efficiently. You can set priority
levels on the Gateway for voice calls, video calls, or both.
The Type of Service (TOS) field in the IP header contains eight bits and
indicates the three abstract quality of service parameters:
Delay (D)
Throughput (T)
Reliability (R)
You can use the abstract parameters to choose the actual service parameters
when transmitting a datagram through a particular network. The abstract
parameters represent the three-way trade off between low delay, high
throughput, and high reliability. Increasing the performance of one of the
parameters can result in reduced performance of the other two. The TOS field in
the IP header is shown in Figure 3-2.

Bit 3: 0 = normal delay, 1 = low delay
Bit 4: 0 = normal throughput, 1 = high throughput

outgoing bandwidth used for data by using the MLP, HMLP and VarMLP
formats.
You can also configure the Gateway to prioritize the transcoding, giving
preference to a particular codec that is applied to calls, thus optimizing the
resource allocation utilized by each call.
The Gateway supports up to 30 video calls on two B channels. If transcoding or
T.120 capabilities are required, the Gateway has to reserve resources for these.
The Gateway can differentiate between those calls that support T.120 and those
that do not. When receiving calls, the Gateway can check whether you are
reserving resources for transcoding or for T.120 capabilities.

ENCRYPTION
The Gateway supports encrypted calls over IP networks. The encryption
conforms to the H.325 standard and supports the following encryption
algorithms:
DES—With an encryption key of 56 bits
AES—With an encryption key of 128 bits
Gateway encryption operates in one of the following modes or can be disabled
entirely:
Best effort—Implements a “best effort” encryption algorithm. If an
endpoint supports encryption, it connects in an encrypted way. If not,
it connects without encryption.
Encryption required—Only connects encrypted calls. Encryption
can either be AES 128 or DES 56. The Gateway does not allow
non-encrypted calls to connect.
Strong encryption required—Only allows AES 128 encrypted
calls. The Gateway does not allow endpoints that do not support AES
128 to connect.

Support H.323 Fast
Start in voice-only call
setup
The H.323 fast start functionality enables endpoints that
support the feature to join a voice conference in the Gateway
more quickly.
Standard call setup requires four round trips of messages
between endpoints before the first media stream is
exchanged between peers. The set of messages includes
Setup/Connect (Q.931 procedure), Master/Slave
Determination (H.245 procedure), Capability Exchange
(H.245) and Open Logical Channel (H.245).
H.323 fast start shortens the time it takes to start a call by
skipping the H.245 phase and combining the call setup
procedure into a single H.225 transaction.
Select to encapsulate H.245 capabilities exchange and
negotiation messages within Q.931 setup messages.
Enable packet handling Select to configure the maximum rate of jitter tolerance in
(may increase call delay) the Network jitter tolerance field. Jitter occurs when IP
packets sent at a steady rate reach their destination at
different speeds. Streams can also split on their way to the
Gateway between different routers. This can cause a “later”
packet B to arrive before an “earlier” packet A, even though
A was sent before B.
Network jitter tolerance If you selected the Enable packet handling (may increase
call delay) check box, then enter the maximum rate of jitter
tolerate in milliseconds. Packet loss occurs when jitter
exceeds the configured rate.

Request ISDN rollover
when less than n B
channels are available
(available in Aethra P20
only)
Select to define when the Gateway uses the ISDN rollover
feature (which is defined in advanced commands—see
Configuring Advanced Commands on page 83 for more
information). When the total number of available B channels
in both PRI ports falls below the number specified in this
field, the Gateway sends a “busy out” message to the PSTN
switch for each of the remaining B channels. The switch
application “busies out” the remaining B channels and
diverts new calls to other gateways on the network with
greater available resources. This setting is only active after
you configure the Gateway to use a 4ESS PRI line.
For example, you specify 10 in the Request ISDN rollover
when less than n B channels are available field and the
number of available B channels falls to 9. The Gateway
sends a “busy out” request message to the PSTN switch. The
PSTN switch application routes new calls through other
gateways on the network. When the total number of
available B channels returns to at least 10, the Gateway
sends a “busy out” cancellation message to the PSTN switch
indicating the restored ability to receive calls. The PSTN
switch makes the “busied out” lines available and attempts
attempt to route new calls through the Gateway.

Support Presentation
Restriction
Select to enable support for the presentation restriction
feature. This feature responds to an instruction from the
calling endpoint to forward or to conceal the endpoint
identifier.
Support H.239
Select to enable support for dual video channels using the
H.239 protocol. This setting is selected by default.
When selected, the Gateway supports H.239 in ISDN-to-IP
calls and in IP-to-ISDN calls. The Gateway identifies the
protocol version that an IP endpoint uses and sends H.239
capabilities only to those endpoints working with protocol
version 4.0 or later. H.239 support has no impact on
Gateway capacity.
We recommend that you do not enable this feature if you
establish communication with endpoints that do not support
H.245 generic capabilities (endpoints based on H.323
version 2 or earlier) as this might cause the endpoints to fail
upon receiving these capability exchanges.
Aethra Gateway Gateways perform Dual Tone Multi-Frequency (DTMF)
detection on IP-to-ISDN calls and on ISDN-to-IP calls. The Gateway can send
DTMF tone information to the IP endpoint in-band only, or both in-band and
out-of-band. The Gateway sends DTMF tone information to the ISDN endpoint
in-band only.
Note For Aethra P20, enabling DTMF detection for video calls reduces the
number of supported calls at 128 Kbps from 30 to 22 when using an E1
connection. Capacities are lower when using a T1 connection

ABOUT DTMF
The signal generated by a DTMF encoder is a direct algebraic summation, in
real time, of the amplitudes of time sine (or cosine) waves of different
frequencies.
An example of the use of DTMF is in touch tone telephone dialing. DTMF tones
are sent out as you dial. For example, pressing “1” sends a tone created by
combining frequencies of 1209 Hz and 697 Hz.
The touch tone system uses pairs of tones to represent the various keys on the
telephone. A “low tone” and a “high tone” are associated with each button (0-9,
*, and #). The low tones vary according to the horizontal row in which the tone
button is located in Table 3-17. The high tones correspond to the vertical column
in which the tone is located. The local telephone company receives each pair of
tones, decodes the number dialed and makes the connection.

About Gateway Services
ABOUT GATEWAY
SERVICES
Gateway services are the mechanism that allows IP network endpoints to choose
the type of connection they want to establish with a terminal or telephone on a
circuit-switched network. A Gateway service defines the maximum bit rate for
each channel, the media content of the stream (voice or data), and the mode of
the call (restricted or non-restricted).
A service prefix identifies a service. The service prefix is an identifier string that
can have up to 31 characters. Valid characters are 0 to 9, pound (#), asterisk (*),
or comma (,). You access a service by dialing the service prefix before the phone
number of the destination. For example, 9* would be identified by the Gateway
as a service prefix if you dialed 9*5673994.
Note If the Ignore caller bearer rate and force service rate setting in the
Advanced section of the Settings tab is selected, a service uses the defined bit
rate. If the Ignore caller bearer rate and force service rate setting is deselected,
the bit rate defined in the service serves as the maximum limit for the service.
The Gateway has two types of services: default and user-defined. Default
services come pre-configured on the Gateway. User-defined services are
services that you can define at any time using the Gateway interface. Upon
registration with a gatekeeper, the Gateway provides the gatekeeper with a list
of Gateway services.
The following topics discuss how you can configure services in the Services
tab:

ISDN call rate according to the bearer capability received in
the setup message from the IP network endpoint.
Note The Auto setting is for video calls only.
If the IP network endpoint has a configured bit rate that is not
one of the options listed in this field, the Gateway uses the
default bit rate configured in the Default Service Bit Rate field
in the Advanced section of the Settings tab.
Note If the Ignore caller bearer rate and force service rate field is
selected when you define a bit rate for a service, the service uses the defined
bit rate. If the Ignore caller bearer rate and force service rate is deselected,
the bit rate you define serves as the maximum limit for that service.

The alerting feature is relevant for incoming voice calls routed
directly to an endpoint (through DID) or to a default extension.
When you select this option, the Gateway sends an alert
message to the dialing ISDN terminal if the call is not connected
within a few seconds. This informs the ISDN terminal that the
call is not yet connected to the local IP endpoint. As a result, the
ISDN terminal continues to hear a ringing sound until the
Gateway connects to the call.
Note The Gateway connects the call even if the endpoint on the local IP
network has not yet accepted it. If the IP endpoint does not accept the call, the
call is rejected and immediately disconnects from the ISDN terminal.
This setting is selected by default. Deselect it to prevent the
Gateway from sending an alert message.

The octet contains eight bits numbered from 1 to 8 and from right to left,
so that Bit 1 is rightmost and Bit 8 is leftmost.
The bits contain values representing the following functions:
Bits 1-7 represents the parameterized field coding value.
Bit 8 is for future use.

ABOUT DIALING
OUT TO THE ISDN
NETWORK VIA THE
GATEWAY
This section describes how to dial between IP and ISDN networks using the
Gateway.
ABOUT GATEWAY
SERVICE PREFIXES
Gateway services define different call types and bandwidths for IP network
endpoints. The services are identified by service prefixes. The network
administrator in charge of the H.323 network is responsible for defining services
and informing users of available services. See About Gateway Services on
page 86 for more information.
When you dial out from an IP network to an ISDN network, you dial a service
prefix followed by a string that usually includes the destination area code, the
destination phone number and any required extra characters such as an asterisk
(*), pound sign (#) or delimiter. The service prefix indicates that the call is to go
through the Gateway, and also indicates the properties of the call such as the call
type or bandwidth requirements.
Note A service prefix should not be the same as the first digits of an IP endpoint
phone number.
Using the Aethra Gateway
119
About Dialing Out to the ISDN Network via the Gateway
Dialing Example 1: Voice calls
The number string 912015294300 is a voice call from an IP network terminal to
an H.323 endpoint on another IP network or to a terminal on the ISDN network.
This number string consists of:
9—The service prefix for a voice call.
12015294300—The destination phone number including the area
code.
Dialing Example 2: Voice calls with the auto bit-rate setting service
The number string 712015294300 is a voice call from an IP network terminal to
an H.323 endpoint on another IP network or to a terminal on the ISDN network
using a service with the bit rate setting of auto. This number string consists of:
7—The auto bit-rate setting service prefix for a voice call.
12015294300—The destination phone number including the area
code.
The bit rate of the call is fixed according to the setting in the source IP network
terminal.
Dialing Example 3: 1B video calls
The number string 821816455318 is a 1B video call from an IP network
terminal to an H.323 endpoint on another IP network or to a terminal on the
ISDN network. This number string consists of:
ABOUT SECOND
NUMBER DELIMITERS
82—The service prefix for a 1B video call.
1816455318—The destination phone number including the area
code.
To dial an outgoing 2B call, you dial the service prefix for 1B calls and the two
B channel phone numbers. Because some H.323 endpoints do not support
dialing long number strings or two phone numbers, you can use a delimiter to
indicate to the Gateway the end of one number and the beginning of the other.
See Configuring Outgoing Call Delimiters on page 56 for more information.
Dialing Example 4: 2B video calls
The number string 821816455318* is a 2B video call from an IP network
terminal to an H.323 endpoint on another IP network or to a terminal on the
ISDN network. Both B channels have the same number. This number string
consists of:
120
Aethra Gateway User Guide
About Dialing Out to the ISDN Network via the Gateway
82—The service prefix for a 2B video call.
1816455318—The destination phone number including the area
code.
*—The second number delimiter. The second number delimiter tells
the Gateway to dial the destination phone number a second time.
Dialing Example 5: 2B video calls
The number string 821816455318*1816455319 is a 2B video call from an IP
network terminal to an H.323 endpoint on another IP network or to a terminal on
the ISDN network. The B channels have different numbers (or your endpoint
does not have two phone number fields). This number string consists of:
82—The service prefix for a 2B video call.
1816455318—The destination phone number including the area
code.
*—The second number delimiter.
1816455319—The second B channel number including the area
code.
Dialing Example 6: 6B bonded high quality video calls
The number string 867455001 is a 6B bonded high quality video call from an IP
network terminal to an ISDN network terminal. This number string consists of:
86—The service prefix for 6B bonded calls.
7455001—The phone number of the destination terminal.
Dialing Example 7: IP-ISDN-IP direct dialing—Gateway supports TCS4
The number string 9825645000^3333 is a call from an IP network endpoint
(Endpoint 1) to an IP network endpoint in another zone (Endpoint 2), through a
public ISDN network, as shown in Figure 4-1. Gateway A dials using TCS4,
while Gateway B is set to receive calls in TCS4 mode.

ABOUT DIALING IN
TO THE IP
NETWORK VIA THE
GATEWAY
The Gateway is responsible for routing incoming calls to the requested H.323
endpoints on the IP network.
ABOUT INCOMING CALL
ROUTING
When a call originating on the ISDN network reaches the Gateway, the Gateway
routes it to an IP network endpoint. This is achieved through one of several
incoming call routing methods that the Gateway supports. You can enable any
number of routing methods for each port, but at least one method must be
enabled for incoming calls to be routed through that port. The Gateway routes
an incoming call from the ISDN network according to the routing methods
enabled for the ISDN port, following this order of priority: DID −>TCS4
−>IVR−>Default Extension.
When a terminal or phone on the ISDN network wants to reach an IP endpoint,
it has to dial at least one of the phone numbers assigned to the ISDN line
connected to the Gateway PRI or BRI ISDN port.
If a routing method fails, the Gateway automatically tries to route the call
through the next routing method in line. If all methods fail, the call is rejected.
The call might also be rejected if the Gateway routes the call to an endpoint that
is busy or not available.
Table 4-1 explains the routing methods.

Routing Methods
Routing Method
Explanation
DID
The Gateway supports two forms of DID (Direct Inward Dialing):
Multiple Subscriber Network (MSN) and sub-addressing.
MSN—The telephone company assigns a group of
phone numbers to a particular ISDN line by the
telephone company. PRI or BRI ISDN lines are usually
assigned multiple numbers in the US and in Europe.
When MSN is used, an ISDN terminal or
phone can dial directly to an IP network
endpoint. The call is still routed through the
Gateway but the Gateway is transparent to the
person dialing from an ISDN terminal.
An H.323 endpoint on the IP network
registers with the gatekeeper using one of the
MSN numbers. When an ISDN terminal dials
the MSN number, the call routes through the
Gateway ISDN port connected to the line with
the MSN service to the endpoint that
registered using the requested number.
Sub-addressing—Sub-addressing is a one-stage DID
dialing mechanism in which a phone sends two
numbers. One number is for routing on the circuit
switched network. The other number is forwarded to the
Gateway inside a Q.931 sub-addressing information
element for IP address resolution by the gatekeeper.
Sub-addressing can also be used for
implementing ISDN fallback when not
enough bandwidth is available for routing an
IP-oriented call over IP. Implementing ISDN
fallback requires the support of the
gatekeeper.

Routing Methods
Routing Method
Explanation
TCS4
TCS4 is a special routing method for incoming H.320 video calls.
TCS4 allows direct inward dialing to an endpoint on the IP
network through the Gateway when DID is not available. H.323
endpoints on the IP network register with the gatekeeper using
extension numbers. When an ISDN terminal dials one of the
Gateway phone numbers followed by a TCS4 extension, the call
is routed directly to the corresponding IP endpoint registered with
that extension.
IVR
IVR (Interactive Voice Response) is a widely deployed automated
call answering system that responds with a voice menu allowing
you to make choices for routing the call. The Gateway can
operate with its own internal IVR or an external IVR located in
another device.
When an incoming call activates the IVR system, it initiates an
interactive session with the caller. The caller directs the call to its
destination endpoint by responding with the dialer to prompts
from the IVR system. If the caller appropriately enters the
destination endpoint phone number, the IVR connects the caller
to the requested IP network endpoint. Otherwise, the call can be
forwarded to an operator. The IVR call transfer is enabled by a
proprietary mechanism that the Gateway uses to transfer a call
from one IP network endpoint to another. The Gateway supports
call transfer for incoming calls from the ISDN network to an IP
network endpoint whether you are using a Aethra gatekeeper or a
third-party gatekeeper. The Gateway internal IVR can handle up
to 30 simultaneous incoming calls.
With the Gateway, you can define an endpoint on the IP network
as an IVR operator (see Configuring IVR Settings on page 55 for
more information). This provides an alternative if the requested
destination endpoint is not available.
Default Extension
Any endpoint on the IP network can be defined as a default
destination for calls using the default extension number
(including the Gateway prefix plus the H.320 or PSTN phone
number) that is registered with the gatekeeper. All calls not routed
through one of the above incoming call routing methods are
forwarded to this endpoint.

ABOUT THE IVR
OPERATOR
You can define an IP network endpoint as an IVR operator and configure the
Gateway ports accordingly. See Configuring IVR Settings on page 55 for more
information.
Dialing Example 8: Direct dialing to an IP network endpoint (Gateway supports DID)
The number string 5645001 is a call from an ISDN network terminal to an IP
network endpoint. This number string consists of:
5645001—The destination endpoint phone number.
The call is routed to the requested endpoint according to its registration identity
in the gatekeeper.
Dialing Example 9: Direct dialing to an IP network endpoint (Gateway supports TCS4
but not DID)
The number string 5645000^5776 is a call from an ISDN terminal to an IP
network endpoint. The dialing endpoint must also support TCS4. This number
string consists of:
5645000—The Gateway phone number.
^—The TCS4 delimiter of the dialing endpoint (if required).
5776—The extension number of the requested endpoint.
Note TCS4 only routes H.320 video calls.
ABOUT DIALING THROUGH
THE IVR
When the Gateway does not support DID or TCS4, you can reach an endpoint
using the Interactive Voice Response (IVR) routing mechanism.
When IVR is enabled, you are answered by a recorded message prompting you
to enter the destination endpoint phone number followed by the pound (#) sign.
If you enter the number of an endpoint that is online and currently not busy, the
IVR connects the call to the requested endpoint.
Dialing Example 10: Dialing to an IP network endpoint through the IVR
The number string 5645000 <wait for the IVR to respond> 5561# is a call
through an IVR routing mechanism. This number string consists of:
5645000—The Gateway phone number.
5561—The number of the requested endpoint.
#—This is required by the IVR for call completion.

About Dialing In to the IP Network via the Gateway
ABOUT DIALING
INDIRECTLY THROUGH AN
OPERATOR
If you do not dial the number of a destination endpoint when requested to do so
by the IVR, the IVR automatically passes you to an operator. You can define any
endpoint on the IP network as the IVR operator (see Configuring IVR Settings
on page 55 for more information).
When IVR is enabled, you are answered by a recorded message prompting you
to enter the destination endpoint phone number. If you do not know the
destination endpoint number, the IVR routes the call from the Gateway using
ISDN to the IP network endpoint that is defined as the IVR operator.

Make sure that at least one routing method is defined for each active
PRI or BRI port. See Configuring Port Call Policies on page 108 for
information about configuring routing for incoming calls.
Make sure that parameters for Interactive Voice Response (IVR) or
the default extension is set to provide assistance for incoming calls
that cannot be directly routed. See Configuring Port Call Policies on
page 108 for information about configuring routing for incoming
calls.
Make sure that the endpoint on the LAN that is designated to process
incoming calls that require assistance is registered with the
gatekeeper and the Gateway.
Make sure that the PRI or BRI numbers are properly configured in the
Gateway.
About Problems with Inbound Calls
Symptom Why are direct-dial calls not reaching the intended endpoint and why
is the IVR not invoked?
Possible Cause The endpoint of the call recipient might not be registered with
a gatekeeper or the telephone line is not working properly.
Recommended Action
For PRI or BRI ports, make sure that the DID number is associated
with an endpoint registered with a gatekeeper and that the number is
included in the registration profile of the endpoint. Incoming calls the
Gateway receives for unused BRI or PRI phone numbers are
disconnected.
Make sure that the BRI or PRI line is in working order.
Disconnect the BRI or PRI line from the Gateway and connect it to a
regular PSTN phone. Dial the number. If the phone does not ring, the
DID line is out of order.
Possible Cause There is a mismatch between the number of digits in the dial
number that the service provider sends in DID calls and the number of digits in the
corresponding E.164 addresses registered with the gatekeeper.
Recommended Action Make sure that the service provider is sending the same
number of digits in calls as specified for the DID service.
Make sure that the service provider is sending the same number of digits in calls
as specified for the DID service.
For example, if the service specifies four significant digits in the number, the
service provider must send four-digit numbers. If the service specifies seven
significant digits in the number, the service provider must sends seven-digit
numbers.

133
About Problems with Inbound Calls
Symptom When TCS4 is used, why do TCS4 calls not reach the requested
terminal?
Possible Cause The TCS4 number might not be registered with the gatekeeper
or the Gateway is improperly configured.
Recommended Action
Make sure that theTCS4 number is associated with an endpoint in the
gatekeeper registration table.
Make sure that the TCS4 option is enabled for the PRI or BRI port.
See Configuring Port Call Policies on page 108 for information about
configuring routing for incoming calls.
Symptom Why is the IVR not responding to incoming calls?
Possible Cause Endpoints placing calls to the Gateway must support DTMF to
use the internal IVR. If the dialing endpoint does not support Dual Tone
Multi-Frequency (DTMF) tones, the IVR forwards the call to the IVR operator or
default extension operator if one is defined (see Configuring Port Call Policies on
page 108 for more information).
When the volume of the DTMF tones generated by the dialing endpoint is low,
the IVR might not recognize one or more of the tones. If the Gateway does not
find an endpoint with a phone number corresponding to the tones dialed, the
IVR treats this string as an incorrect number and disconnects the call.
Recommended Action
134
Aethra Gateway User Guide
Make sure that the parameter that allows the Gateway to accept
DTMF for incoming calls is enabled. See Configuring IVR Settings
on page 55 for information about how to set the IVR parameter.

INDUSTRY CANADA
Only Aethra SpA qualified service personnel may repair the
equipment.
The Industry Canada (IC) label identifies certified equipment. This certification
means that the equipment meets certain telecommunications network protective,
operational and safety requirements. The IC does not guarantee the equipment
will operate to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The
equipment must also be installed using an acceptable method of connection. In
some cases, the company's inside wiring associated with a single line individual
service may be extended by means of a certified connector assembly (telephone
extension cord). The customer should be aware that compliance with the above
condition may not prevent degradation of service in some situations.
Repairs to some certified equipment should be made by an authorized
maintenance facility designated by the supplier. Any repairs or alterations made
by the user to this equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user to disconnect the
equipment.
Users should ensure for their own protection that the ground connections of the
power utility, telephone lines and internal metallic water pipe system, are
connected together. This precaution may be particularly important in rural areas.
The abbreviation, IC, before the registration number signifies that registration
was performed based on a Declaration of Conformity indicating that Industry
Canada technical specifications were met. It does not imply that Industry
Canada approved the equipment.
Warning Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or electrician, as
appropriate.

ESD Procedures
GROUNDING
The power cable of the Aethra Gateway unit should only be connected to a
power outlet that has a protective earth contact. Do not use an extension cord
that does not have a protective conductor (ground). The Aethra Gateway unit
can become dangerous if you interrupt any of the protective conductors
(grounding) or disconnect any of the protective earth terminals.
HIGH VOLTAGE
Disconnect the Aethra Gateway unit from the power line before removing the
cover. Avoid any adjustment, maintenance, or repair of an opened chassis under
voltage. These actions should only be carried out by a skilled person who is
aware of the dangers involved. Capacitors inside the chassis may still be
charged, even if the unit has been disconnected from the power source.
ESD PROCEDURES
To prevent damage to the Aethra Gateway unit by random electrostatic
discharge (ESD), the use of wrist straps is highly recommended.
