1 OVERVIEW

What is the IP Dual Port PBXgateway and Remote?

The PBXgateway is a two-user telephony device providing remote teleworkers with seamless connectivity to the corporate PBX and all of the associated functionality. The PBXgateway connects to the PBX and the user connects to an Remote at the remote site. Teleworkers, typically working from an off-site location, can place or receive calls through the corporate PBX as if they were at the main office.

What does it do?

Citel Technologies EXTender products allow workers at branch offices or home offices to interact with the corporate PBX as if they were on-site. A simple IP connection will deliver the voice path and telephony features over the IP network to the corporate head office. The physical location of the worker will be completely transparent.

How does it do that?

The digital telephone connects to the Remote via an RJ-45 telephone jack and the telephone traffic is sent out to the LAN via a 10/100BaseT Ethernet connection to a PBXgateway at the corporate office. An optional PSTN FXO port on the Remote offers a separate analog connection direct to the PSTN. This can be used for local dialing or contacting local emergency services.

6. Power and Wiring

7. The system is designed to operate at 120-240V AC. Do not apply power to the

PBXgateway or Remote until you are instructed to do so in the installation procedure

8. Install the PBXgateway or Remote power supply and cabling away from high

power/high RF noise devices such as computers, fans, fluorescent ballasts and power supplies

9. Use good wiring practices. Do not run wires over fluorescent lights, computers, air

conditioners, etc., as this can introduce noise

10. The distance between the PBXgateway and the PBX it is to be connected to should

Essential Configuration – PBXgateway

Once the PBXgateway and Remote are connected, the MC (Management Console) allows for the configuration of the individual ports according to the requirements of the individual users and any network requirements according to the corporate IT Manager. The following is a detailed description of the programming areas that would be considered “essential” to the proper operation of the PBXgateway.

Do NOT connect the PBXgateway to the PBX or connect the digital telephone(s) to the Remote until the Setup Wizard has been run. An improperly configured

Essential Port Setup

PBXgateway can cause damage to the PBX line card and an improperly configured Remote can cause damage to the digital telephone sets.

The PBXgateway Port configuration screen is shown below:

Path: Gateway->Configuration->Port->Port_1 (and Port_2)

Figure 10: PBXgateway - Port Configuration Screen

1. Port Enabled Yes/No - Disabling any unused ports is recommended in order to

reduce any unnecessary traffic on the network link.

2. Setting User IDs – A user ID “maps” which port on the Remote connects to a specific

port on the PBXgateway. There are several ways in which this is accomplished:

a) By default, Port Matching is enabled (

If no user ID is entered on the Remote the user will be prompted to enter the User ID when connecting to the PBXgateway (by default it is the PBXgateway port number). The administrator must advise the users of what number to enter when connecting (i.e. ‘1’ for port 1, ‘2’ for port 2).

b) User IDs can be manually input either in the individual port menus or by use of

the User List feature ( management of multiple users. The main difference with the User List is that a user can be assigned multiple ports to connect to (typically not used on a one or two port system).

c) When using multiple Remotes to connect to a single PBXgateway the User IDs

must be used to specify which user is to connect to which ports on the

PBXgateway. It is recommended that User IDs reflect the user’s extension

Path: Gateway->Configuration->Connect).

Path: Gateway->User List). The User list allows for easier

Page 34

IP Dual Port PBXgateway and Remote System Administrator’s Guide

number. For example, if John Smith’s internal extension number was 5637 then 5637 should be used as this port’s User ID on the PBXgateway and Remote.

3. Setting the Voice Parameters – Voice parameters are set on a by-port basis and are

used to “fine tune” voice processing and bandwidth usage. Users will have to disconnect from the PBXgateway and reconnect for any changes to these parameters to take affect.

It should be noted that the default settings for the voice parameters are usually sufficient and should not require adjustment. It is, therefore, recommended that a few “test” calls be made to identify any voice quality issues prior to configuring the voice parameters. The Voice Parameters screen is shown below:

Path: Gateway->Configuration->Port->Port_1 (and Port_2) ->Voice

Figure 11: PBXgateway – Voice Configuration Screen

a) Method (of compression) – Selecting different voice compression methods can

reduce network bandwidth requirements. The four methods offered are:

i) ADPCM32 (60Kbps)

ii) ADPCM24 (50Kbps)

iii) G.729A (30Kbps)

iv) G.711 (90Kbps)

It should be noted that a highly compressed voice path can have a negative affect on voice quality. For example, G.729 is more compressed than G.711 resulting in less bandwidth usage but this can have an affect on voice quality. See

Calculating Bandwidth Requirements: for calculating bandwidth requirements.

b) Path – Another method of reducing bandwidth is by configuring how the voice

path is allocated. When the path set to Constant the bandwidth is always available for that port (recommended). When set to Dynamic the bandwidth for the voice path is allocated only when the user goes offhook to invoke or receive a call. This is useful if there are restrictions for bandwidth usage. In Dynamic mode if bandwidth is not available to invoke or receive a call the user will receive an audible error tone and a visual error message on the telephone.

Page 35

IP Dual Port PBXgateway and Remote System Administrator’s Guide

c) Companding – This is a telecommunications standard, by region, for the

transmission of voice. In North America the standard is µLaw (pronounced mu law) and in Europe the standard is aLaw. When the companding is not set correctly voice will sound choppy and garbled.

d) DTMF (Definity PBX only) – The PBXgateway must be set to deliver the DTMF

tones either within the voice path (inband) or not within the voice path (out-ofband). This is based on the functionality of the PBX. If the PBXgateway is configured for the Definity PBX type then DTMF should be set to “out-of-band.”

The DTMF parameter will only appear if the PBX type is set to Definity. If the DTMF value is not set properly the routing of the Analog port Emergency Number will fail (see

Essential Configuration of the Analog Port on setting up the Analog port).

e) Tx Volume Level – The outgoing volume level of the signal being sent to the PBX

can be adjusted to decrease the amount of echo that may be experienced during calls in some areas. The transmit level can be adjusted from 25% to 150%.

f) Rx Volume Level - The incoming volume level of the signal being sent to the PBX

can be adjusted to decrease the amount of echo that may be experienced during calls in some areas. The transmit level can be adjusted from 25% to 150%.

g) Silence Detection – When voice is transmitted over the network it is treated as

data. If silence detection is enabled then no “data” is sent across the network during silent periods of a conversation. This will further assist in reducing bandwidth usage.

h) Jitter Delay – This is the amount of delay (in milliseconds) in sending voice

packets to account for the “Jitter” in a particular IP network. If not set properly voice may sound choppy. Increasing the Jitter Delay parameter reduces audible audio noise and helps prevent this from occurring. The Jitter Delay can be adjusted from 20 milliseconds (ms) to 250 milliseconds (ms). If required, it is recommended to begin at 20 to 30 ms when adjusting for network jitter.

Calculating Jitter Delay:

The Jitter Delay should be set to a multiple of the Voice Packet Size Time Equivalent. This is the amount of time taken, in milliseconds (ms), by the combined voice packets. For example, if using G.729A, where each voice packet is equivalent to 10ms of time, and you have a packet size of 2 then the Voice Packet Size Equivalent is 20 ms (2 packets x 10ms).

i) Packet Size – The Packet Size can also be increased to reduce packet loss and

bandwidth requirements but it may cause some additional delays in voice delivery. It is recommended to leave this at the default value of 2. It may become necessary to increase this value to 4 for some packet networks or if using a

higher compression such as G.729 (see the Method section in

for more details).

Essential Configuration of the Analog Port

The Single and Dual Port Remote are both available with an optional analog port for local dialing. Labeled “Analog” on the back of the Remote, it provides a PSTN (Public Services Telephone Network) connection to an analog telephone line for the purpose of reaching local emergency services (fire, police, etc.) or for making local calls. The main Analog port configuration screen is shown below:

If a user dials emergency services on the digital set at the remote location when the telephone is connected to the Remote and “linked” to the PBXgateway you will reach the

Figure 18: Remote – Analog Port Main Configuration Screen

Page 43

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Within the Key Mapping menu structure is the Analog Key field. The Analog Key field is programmed with the telephone line key (of the digital set) that will be used to access the analog line. The Analog Key configuration screen is shown below:

Path: Remote->Configuration->Port->Port_1 (and Port_2) ->More->Key Mapping

Figure 19: Remote – Analog Key Configuration Screen

1. Configuring the Analog Key – This is the key the user would press to access the

analog line. Keys 0 to 15 are supported and the default setting is Key 4.

2. Enabling the Speaker Key (Nortel Norstar PBX only) – When set to enabled this

allows for the user to have handsfree operation for the FXO port when not connected to the PBXgateway.

Operation of the Analog port:

i. If power to the Remote is disrupted the analog line will not be available. ii. Calls made using the analog port are not routed through the PBXgateway and

subsequently the corporate PBX. Therefore, none of the PBX features will be available. Only features supplied by the PSTN will be available to the user.

iii. The Analog port can be used whether the network connection is established with the

PBXgateway or not. If the connection is not available the telephone will show

“Press 1 to connect…” and the analog line can be accessed by pressing the preprogrammed Analog Key on the digital set, pressing the speaker key or by going offhook.

iv. If the connection to the PBXgateway is established (normal operation) the

telephone set will display the time and date and the analog line can be accessed by pressing the preprogrammed Analog Key on the digital set, entering the Analog Dialing Prefix or by dialing the Emergency Number (discussed in detail on the next page).

The Analog Port configuration menu allows for programming the operational parameters for the appearance, access and routing of analog calls. The Analog Port configuration screen is shown on the next page:

Page 44

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Path: Remote->Configuration->Port->Port_1 (and Port_2) ->More->Analog Port

Figure 20: Remote – Analog Port Settings Configuration Screen

1. Analog port Enabled Yes/No – The analog port is configured separately for the

individual users. ‘Yes’ will enable access to the Analog port and ‘No’ disables it.

2. Setting the Ring preference – The user can have incoming calls to the Analog port

configured to ring or be silent. If Ring is set to ‘No’ then the line indicator will still light up to indicate a call but it will not have an audible ring.

3. Entering the Analog Dialing Prefix – As with most businesses, to reach an outside

line it’s usually necessary to dial an access code (i.e. 9) and then the number. This is the same principle as the Dialing Prefix for the analog port. If the user has a telephone that does not support preprogrammed keys or all the preprogrammed keys are populated the analog port can be accessed by entering the access code.

4. The Emergency Number – The purpose of the Emergency Number is to route a

predetermined dial string to the Analog port automatically. For example, if the Emergency Number was 911 (or 999) and the user goes offhook and dials 911 (or

999), this call will be automatically routed to the Analog port and then the call would be made. Any valid phone number can be used – the phone number to the corporate main security desk, for example.

If the PBXgateway is connected to an Avaya PBX type it must be set to deliver the DTMF tones either within the voice path (in-band) or not within the voice path (out-of-band) - this is based on the functionality of the PBX. If the PBXgateway is configured for Definity then the DTMF parameter should be set to “out-of-band.” If the DTMF value is not set properly this will result in routing of the Analog port Emergency Number to fail (refer to

Configuration of the Analog Port

). The DTMF parameter will only appear if the PBX type is

Essential

set to Definity.

Advanced Configuration – PBXgateway

Although usually not required, the advanced features may be used to assist with managing the PBXgateway or trouble shooting voice issues. The following is a detailed description of the programming areas that would be considered “advanced” to the proper operation of the PBXgateway. Please consult the Advanced Configuration section prior to contacting customer support should issues arise.

Advanced Port Setup

The PBXgateway Port configuration screen is shown below:

Path: Gateway->Configuration->Port->Port_1 (and Port_2)

Figure 21: PBXgateway – Port Configuration Screen

1. Port Descriptions – The port description accepts 16 characters of text to identify the

user of a specific port. Typically the user’s name would be entered (i.e. John Smith).

2. Setting a Connect Password – A Connect Password restricts access to the telephone

port and is typically used in conjunction with the User ID feature. If the password is set only on the PBXgateway then the user will have to manually input the password when

connecting. If, however, a password is entered for a port on the PBXgateway and

Remote the user will not be required to take any action.

3. Configuring the Line Signaling (Nortel Norstar PBX only) – On some installation

environments a clicking noise may be present in the audio path. This is caused by errors in the duty cycle of the signaling wave form. This setting can be adjusted from 0 to 7. Some experimentation may be required to eliminate any audio issues that may arise.

Page 46

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Advanced System Parameters – System Name/Connect Speed

The PBXgateway system configuration screen is shown below:

Path: Gateway->Configuration->System

Figure 22: PBXgateway – System Name/Connect Speed Configuration Screen

1. Assigning a system Name – The Name field in the PBXgateway is used for

identification purposes only and appears next to the software revision (see above). This makes it easier for an administrator when managing multiple sites. Typically the geographic location of the unit is input “Seattle Office” for example. Any text up to 15 characters can be input in this field.

2. Changing the Console baud – This is the speed at which information is transmitted to

and from the PBXgateway through the console port labeled “COMM” on the back of the unit. The baud rate can be changed to 2400, 4800, 9600, 19200 or 38400. The default is 9600.

Advanced System Utilities – Administrator Password

The PBXgateway utilities configuration screen is shown below:

Path: Gateway->Utilities->System->Set Passsword

Figure 24: PBXgateway – Administrator Password Screen

1. The Set Password function - The administrator password can be a maximum of 10

digits and it restricts unauthorized access to the Management Console (MC). It is important to set an administrator password because the unit’s password is blank (no password) by default. Keep the password in a safe place.

If the unit’s password is lost or forgotten please contact a customer support representative at 1-877-248-3587 or [email protected]. Individual port passwords are not affected.

Page 49

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Advanced IP Parameters – Prioritizing Voice (DiffServ)

The PBXgateway supports the Differential Services packet prioritization protocol. DiffServ can be chosen to prioritize packets within the network.

All nodes in the network must be configured to prioritize traffic based on DiffServ in order for this feature to function properly.

The Type of Service configuration field is shown below:

Path: Gateway->Configuration->Connect->RVP_Over_IP

Figure 25: PBXgateway – DiffServ

1. Entering the Type of Service – The administrator can enter a type of service value

between 0 and 255. This information should be obtained from the corporate IT Manager prior to configuring the unit.

More on Differential Services:

Each RVP_Over_IP voice packet contains a Type of Service (ToS) byte. Within this byte are three bits which are the class of service field. The class of service field is always automatically set to low delay for RVP_Over_IP voice packets by the EXTender 4100.

Also within the ToS byte are three bits for Differential Services. With the DiffServ implementation the system administrator is given the option of choosing how the three DiffServ bits are set. These bits tag the traffic among other packets that have the class of service field set to a low delay, according to the way the corporate network is configured for DiffServ traffic.

Page 50

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Advanced IP Parameters – Static Routes

Typically, a router uses dynamic routes to learn how to reach network destinations.

Dynamic routes are determined from the information exchanged by the routing protocols and, as the name implies, these may change as networks conditions change. Static Routes are used by the router when it does not have a route to a destination that has a better (lower) preference value, when it cannot determine the route to a destination, and/or when it is forwarding packets that cannot be routed. The PBXgateway Static Routes configuration screen is shown below:

Path: Gateway->Configuration->IP->Static_Routes->route_1 (and route_2 to route_10)

Figure 26: PBXgateway – Static Routes Configuration Screen

The Administrator assigns the IP Address, Subnet Mask and Gateway Address for each route. Routes 1 – 10 all have the same menu items.

1. Configuring the static route Address – The IP address(es) should be obtained from

the corporate IT Administrator prior to configuring the PBXgateway.

2. Configuring the Subnet Mask - The subnet mask(s) should be obtained from the

corporate IT Administrator prior to configuring the PBXgateway.

3. The Default Router – The default router(s) should be obtained from the corporate IT

Administrator prior to configuring the PBXgateway.

Page 51

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Advanced IP Parameters – DNS

This parameter allows the System Administrator to find the PBXgateway by an assigned name. Domain Name Server (DNS) is used in IP networks for translating a host domain name into an IP address. This information is stored in a DNS server. Enabling DNS on the PBXgateway allows the System Administrator to search for it by its name and/or IP address. The DNS parameter is NOT enabled by default. The PBXgateway DNS (Domain Name Server) configuration screen is shown below:

Path: Gateway->Configuration->IP->DNS

Figure 27: PBXgateway – Static Routes Configuration Screen

1. Setting DNS to Enabled – ‘Yes’ will enable DNS and ‘No’ will disable DNS.

2. The Server IP Address1 (to 4) – Enter the address(es) of the DNS servers up to 15

characters. The Server IP addresses should be obtained from the corporate IT Administrator prior to configuring the PBXgateway.

3. Entering the Domain Name – The domain name (i.e. Citel) is entered in this field to a

maximum of 20 characters. The Domain Name should be obtained from the corporate IT Administrator prior to configuring the PBXgateway.

Page 52

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Advanced Configuration – Remote

Although usually not required, the advanced features may be used to assist with managing the Remote or trouble shooting voice issues. The following is a detailed description of the programming areas that would be considered “advanced” to the proper operation of the Remote. Please consult the Advanced Configuration section prior to contacting customer support should issues arise.

Advanced Port Setup

The Remote Port configuration screen is shown below:

Path: Remote->Configuration->Port->Port_1 (and Port_2)

Figure 28: Remote – Port Configuration Screen

1. Port Descriptions – The port description accepts 16 characters of text to identify the

user of a specific port. Typically the user’s name would be entered (i.e. John Smith).

2. Auto Connect – The Remote ports can be set to auto connect in case of a lost

connection (or “link”) between the PBXgateway and the Remote across the network. Normally, if the user was not connected the set would display “Press 1 to connect…” but with auto connect enabled the ports would attempt to connect automatically at different time intervals. This means that the Remote will wait a few seconds between tries (up to a maximum of one minute) before it stops attempting to reconnect.

3. Diversion (Ericsson only) – When set at “Enabled” this will tell the PBX to enable the

Diversion feature when the user disconnects from the PBXgateway (at the end of the business day, for example).

Diversion is a function of the PBX and this field will only be presented when the Remote is configured for the Ericsson PBX type.

4. Setting a Connect Password – A Connect Password restricts access to the telephone

port and is typically used in conjunction with the User ID feature. If the password is set only on the PBXgateway then the user will have to manually input the password when

connecting. If, however, a password is entered for a port on the PBXgateway and

Remote the user will not be required to take any action.

Page 53

IP Dual Port PBXgateway and Remote System Administrator’s Guide

5. Displaying text using Banner – The Banner field can be used to display simple

messages on a telephone equipped with 2-line display. The text appears when the user is off-line (not connected to the PBXgateway). Typically, the company name is displayed. A maximum of 15 characters can be entered in this field.

6. Configuring the Line Signaling (Nortel Norstar PBX only) – On some installation

7. Enabling Active Call Monitoring (Nortel Norstar PBX only) – If the user is monitoring

another station for call activity this should be set to Enabled.

Page 54

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Advanced Call Suspend Setup

The Call Suspend feature allows for the administrator to reduce IP traffic across the network by bringing down the IP connection temporarily when all ports are inactive for a configurable period of time. When the Timeout value is reached, the phones will display “Suspended” and Management Console (MC) will show the port status as “Call Suspended” signifying that they are in the Call Suspend mode. Whenever a user goes offhook or an incoming call occurs, the IP connection is restored and all phones are taken out of Call Suspend mode. The Call Suspend screen is shown below:

Path: Remote->Configuration->Connect->RVP_Over_IP->Port_1 (and Port_2) >Call_Suspend

Figure 29: Remote – Call Suspend Configuration Screen

1. Setting Call Suspend to Enabled – When set to “Enabled” the Remote will enter the

Call Suspend mode at the configured time.

2. Entering the Timeout value – A timeout can be configured to allow the administrator

to set when the ports will fall in to Call Suspend. Typically, at the end of the business day. The timeout can be set for between 5 and 240 minutes.

3. Configuring the Minimum Connect Time – A minimum connect time can also be

programmed to ensure that the connection to the PBXgateway will remain connected for a specified period of time prior to falling in to Call Suspend mode. The minimum connect time can be set for between 0 and 240 minutes.

Timeout vs. Minimum Connect Time:

For example, when the user initially connects by pressing “1” on the digital set connected to the Remote the port will fall into Call Suspend mode at the Minimum Connect Time. If, however, the user invokes or receives a call that is longer that the Minimum Connect Time value the port will fall into Call Suspend mode at the Timeout value.

4. Setting for Remote Wakeup Only - If enabled, only activity at the Remote side will

wake the system from Call Suspend (going offhook, for example). This ensures that any calls placed after hours to the corporate office will not cause the IP link to be reestablished.

Page 55

IP Dual Port PBXgateway and Remote System Administrator’s Guide

5. Setting the monitoring Mode – There are three activities that can trigger the system to

wake from Call Suspend:

a) Ring Mode – If ringing is detected on the port it will wake from Call Suspend. b) Lamp Mode – If lamp activity is detected on the port it will wake from Call

Suspend (Indicators must also be configured – see below)

c) Voice Mode – If a voice call is detected on the port it will wake from Call Suspend.

6. Configuring the Indicators – Used in conjunction with Lamp Mode (above), these are

the line keys that will be monitored. If activity is detected on these configured line keys the port will wake from Call Suspend mode.

7. Waking on ACD Tone – For use with Automatic Call Distribution systems, set to ‘Yes’

this will allow for an ACD tone to be presented when waking from Call Suspend mode by an incoming call.

Advanced System Parameters – System Settings

The Remote system configuration screen is shown below:

Path: Remote->Configuration->System

Figure 30: Remote – System Settings Configuration Screen

1. Assigning a system Name – The Name field in the Remote is used for identification

purposes only and appears next to the software revision (see above). This makes it easier for an administrator when managing multiple sites. Typically the geographic location of the unit is input “New York Office” for example. Any text up to 15 characters can be input in this field.

2. Configuring to Use Gateway Time – The log files for the Remote can be stamped

using the locally configured time (see

Advanced System Utilities – Time and Date for

time and date configuration) or by using the PBXgateway time. Using the PBXgateway time is recommended so that time events recorded are consistent at both the corporate facility and the remote site. This feature will assist during trouble shooting should the need arise.

3. Setting the Gateway Time Offset – Enter a value that represents the time difference

between the PBXgateway and the Remote. This is used to compensate for the time difference between cities. For example, if the PBXgateway is at a corporate office in Seattle and the Remote is at a branch office in New York set this value to +3. This ensures that the log time stamp and the telephone display use the correct time.

4. Changing the Console baud – This is the speed at which information is transmitted to

and from the PBXgateway through the console port labeled “COMM” on the back of the unit. The baud rate can be changed to 2400, 4800, 9600, 19200 or 38400. The default is 9600.

5. Enabling for IP Office (Definity and Magix only) – If telephone sets normally used for

Avaya IP Office are used on the system when it is configured for the Definity or Magix PBX type then the IP Office parameter must be set to ‘Yes’. Refer to

Supported Telephones – Definity, Magix and IP Office

The IP Office field will only be presented when the Remote is configured for the Definity or Magix PBX types.

7 CALCULATING BANDWIDTH

REQUIREMENTS:

An important factor in the successful installation and administration of the PBXgateway and Remote is determining the necessary bandwidth required. Determining the appropriate amount of bandwidth is a function of two factors:

 Number of users (telephones)

 Voice compression required for each user

Determining the Number of Users

The number of users is simply the number of telephones that will be “extended” at the remote site. In the case of the Remote there can be one or two users per device.

Determining Voice Compression

The PBXgateway provides various voice compression methods (CODECs). The method chosen will determine the amount of bandwidth required. The total bandwidth required, including overhead, depends upon the compression method being used:

Compression Bandwidth per Telephone

G.729A 30 Kbps

ADPCM24 50 Kbps

ADPCM32 60 KBPS

G7.11 90 Kbps

Table 4: Determining Voice Compression

The total amount of bandwidth required for the PBXgateway and Remote application can be determined by using the

Selecting a Compression Method

Optimum voice quality is achieved when using the G7.11 voice compression method. However, the high voice quality requires the largest amount of bandwidth due to the low compression.

Bandwidth Management Formula on the next page.

The highest voice compression is achieved using G.729A. With this voice compression method the voice quality is considered “near toll” and the bandwidth requirements are significantly reduced.

If conversation quality is a high priority and bandwidth is not a factor then G.711 or ADPCM32 would be recommended. If, however, bandwidth is a factor and voice quality is not paramount then G.729A or ADPCM24 is recommended.

Page 64

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Bandwidth Management Formula

If different voice compression methods are required for each port being extended the following formula will assist in calculating the required bandwidth:

(A x 30) + (B x 50) + (C x 60) + (D x 90) = E

where:

 A = number of ports using G.729A

 B = number of ports using ADPCM32

 C = number of ports using ADPCM24

 D = number of ports using G.711

 E = total bandwidth required

Page 65

IP Dual Port PBXgateway and Remote System Administrator’s Guide

8 USING SNMP

The PBXgateway and Remote support Simple Network Management Protocol (SNMP) for ease of monitoring multiple installations. A third party software application is required to be operating on the network administrator’s workstation in order to monitor and review the SNMP traps.

 SNMP: The network management architecture used for managing virtually any

network type including TCP/IP, IPX and others. SNMP operates on top of the Internet Protocol and its purpose for the PBXgateway and Remote is to flag error or failure conditions and automatically notify the administrator.

 Trap: The SNMP mechanism permitting a device to send an alarm to the

administrator’s work station.

 MIB: The administrator must load an MIB file (Management Information Base) to

properly monitor the PBXgateway and/or the Remote. This file contains numerous tables (see next page) based on the Management Console status tables and provides information such as error counts and the on/off status of the units.

 3

Party Software Application: An application such as HP

SNMP Setup

This section covers information for installing all support software, accessing and identifying specific trap information, viewing the “Alarm Log” and walking through the MIB.

Set Up Steps

1. Load a third party-network management software package, such as HP OpenView®,

onto the PC used to manage the PBXgateway and Remote units.

2. Install the units’ configuration files, onto the same PC.

3. Add the units’ MIB to the third party-network management software package

database. This will allow the software to access the status and configuration variables of the PBXgateway and Remote.

4. Set the password (Community String) to allow access to the units.

5. Format the Trap error messages from the PBXgateway and Remote into an easily

read form.

6. Enable SNMP within the MI.

Installing the MIB Files

The MIB files are necessary for the third party software to read the PBXgateway and Remote status tables, and to receive readable SNMP Trap error messages.

Work with the following files:

mibs\Remotexxxx.mib (where xxxx refers to the Remote release).

Copy to: c:\ov\mibs

This file is the MIB for control of the Remote, in this case. This file must be compiled into the third party software package.

Setting the Community Password

The units come with a default SNMP read password also known as a Community String. This password must be specified inside the third party software to allow the user to view MIB objects.

Before setting the password, the units must have an IP Address assigned by the network administrator and must be part of the software “Network View”.

1. Access the “Network View” menu from within the third party software. Click on the

Icon of the device to be configured. Each Icon should be titled with the IP Address for the device.

2. Type in the password next to Community. Click

password is: “public.” The Set Community password is not and may be ignored.

OK. The default read (community)

Page 72

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Configuring the Trap Host

The PBXgateway and Remote send alarm messages (SNMP Traps) to any Trap Host with an associated IP Address that has been entered into the User Interface SNMP Configuration Menu. These slots are named Trap Host 1, Trap Host 2, etc.

Trap Customization

The third party software will receive and display Trap messages from the units. But without some configuration these messages will be simply a list of numbers, as shown:

Figure 36: Non-Customized Trap Messages

To display friendly and readable Trap messages, the software can be configured to display all the information contained in the Trap Error messages sent by the PBXgateway or Remote. Trap messages correlate with “log messages” within the MI.

Defining a Fatal Trap

Here is an example of setting up “HP Openview for Windows” to receive the Log messages from the PBXgateway and Remote.

1. From within the third party software, navigate to the Add Trap window.

2. In the box Number: type: “1”

3. In box Name: type “Gateway (or Remote) Fatal Error”

4. In box Severity: select choice “Critical”

5. In box Description: type “$E, $1”

6. Delete any existing text.

7. Click on the OK button.

Defining an Error Trap

1. From within the third party software, navigate to the Add Trap window.

2. In the box Number: type: “2”

3. In box Name: type “Gateway (or Remote) Error”

4. In box Severity: select choice “Major”

5. In box Description: type “$E, $1”

6. Click on the OK button.

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Using SNMP to monitor and Troubleshoot Problems

Here is an example of how to use SNMP management to monitor the PBXgateway and Remote.

Example:

You have an PBXgateway with an IP address of “10.2.1.50”. The Remote has an IP address of “10.5.3.50”. You want to monitor if there are lost signal conditions.

Use your SNMP manager to browse the “Remote.mib” and create a TRAP condition on the object name “extStatLostSignalStat”. Get the current threshold value, for example “0”. Trigger the TRAP when the threshold exceeds “0”.

If there is a Lost Signal condition, as shown in the MI menu under “Status->Connect>Connect Stats”, or anything higher than zero, a message will be indicated on the SNMP manager.

9 USING SYSLOG

Configuring Syslog

The Syslog feature allows for the writing of the log file information to a centralized logging server if required. System trouble shooting is performed by configuring the log to report specific events in a prioritized manner. The Syslog configuration screen is shown below:

Path: Gateway (Remote) ->Configuration->IP->Syslog

Figure 38: Configuring Syslog

1. Enabled Yes/No – Enabling allows for the log data to be written to the Syslog host

and disabling turns this feature off.

2. Host – This is the IP address that the log file information is to be written to.

3. ID – The ID is used to identify the specific unit that the log is being generated from.

The range is from “local0” to “local7.”

4. Default Priority - Allows for the selection of what log types will be displayed first in

the log file for the “<default>” setting.

5. SYS Priority – Can be left at the default of “Info” or be changed to Fatal, Error,

Warning, Info, Debug or Trace.

6. MGMT Priority – Can be left at the default of “Info” or be changed to Fatal, Error,

Warning, Info, Debug or Trace.

7. Net Priority – Can be left at the default of “Info” or be changed to Fatal, Error,

Warning, Info, Debug or Trace.

8. Port Priority – Can be left at the default of “Info” or be changed to Fatal, Error,

Warning, Info, Debug or Trace.

Third Party Application for Syslog

A third party application is required for receiving the log file information. An application such as Kiwi Syslog Daemon is a freeware Syslog Daemon for Windows. It receives, logs, displays and forwards Syslog messages from hosts such as Citel’s EXTender products, routers, switches, Unix hosts and any other syslog enabled device. However, any third party Syslog application can be used.

For the Kiwi Syslog Daemon it is a simple matter of opening the application. The log files will be received immediately (assuming a valid Host IP address has been input). An example of the Kiwi Syslog Daemon application is shown below:

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Trouble Shooting Procedures

The following procedure provides a step-by-step process for identifying and rectifying installation problems with the PBXgateway and Remote. Each step is a question requiring a “Yes” or “No” response. Each response has a series of checks or actions necessary to correct the problem.

Prerequisites:

 Both units must be powered-up with some LED blinking patterns visible.

 Both units must be connected to an active network capable of sending and receiving

packets.

System Status LEDs

After the units have completed the self-diagnostic tests, is the Status 1 LED on (solid green) on each unit? If the Status 1 LED is not lit, check that the power cable is properly connected. Below is the complete list of the System Status LEDs:

System Status LED Status

Power off Status LED 1 – Off

Status LED 2 – Off

Hardware problem detected during memory test

Hardware problem detected during Self Test

Memory Tests Status LED 1 – Green Flicker

Loading Firmware Status LED 1 – Solid Green after Flicker

System firmware load Failed Status LED 1 – Green Flashing

Table 9: System Status LEDs

Status LED 1 – Off Status LED 2 – Solid Green

Status LED 2 – Off

Status LED 2 – Green Flashing

Port Status LED

After the units have gone through the self-diagnostics tests and loading the runtime image, the telephone port LED should be solid green. This indicates that the telephone port is connected to a digital port on the PBX and to a telephone connected to the Remote, but not extended.

1. If the Port LED is OFF this indicates the port is disabled. The telephone port is

enabled by default. To confirm the telephone port status go to Gateway (Remote) >Configuration->Port and check that the

2. If the port LED blinks with a green flicker this indicates that the port is enabled but

there is a bad connection to the PBX or phones.

3. If the ports are ready, press ‘1’ to connect to the PBXgateway. (If Auto-connect is

enabled, it is not necessary to press ‘1’.) As the telephone is connected the LED will begin to flash slowly. This means that the telephone is enabled but still not in use (onhook).

4. Check the log messages within the MC for obvious port errors.

5. Are there any messages displayed on the telephones connected to the Remote?

Enabled field is set to “Yes.”

Page 81

IP Dual Port PBXgateway and Remote System Administrator’s Guide

6. Place a call using a telephone connected to the Remote. As the remote user places a

call the LED will begin to flash faster. This means that the telephone is extended and in use (off-hook) by the remote user.

7. Check the wiring to the PBX.

8. Is the Voice Quality acceptable?

Resetting the Port

Try resetting the port on the PBXgateway and Remote:

1. To reset the telephone ports:

Path: Gateway (and Remote) ->Utilities->Diagnostics->Reset Port

Test the IP Connection

If all of your Status LEDs indicate the units are installed properly, but you still cannot connect the remote telephone, you should test the IP connection. This test will not run if the telephone is off-hook (in an active call).

1. Access the MC.

2. Access the diagnostics menu via Gateway (Remote) ->Utilities->Diagnostics->Test IP

3. Using the default values, select “Begin test.” This test will send voice packets to the

offsite unit and will count the packets as they are sent back.

4. The MC will run the test and, upon its completion, a test results window appears as

shown below.

Figure 41: Test Results Window

5. From a PC on the remote network make sure that you can reliably ping the

PBXgateway.

6. From a PC on the corporate network, make sure you can reliably ping the Remote on

the remote network.

Voice Quality Expectations

The Remote uses an industry-standard voice compression method to allow multiple users to connect using less bandwidth. While the voice quality should remain excellent in all circumstances, you may notice some minor issues depending on the voice compression selected. The person you are talking to on the other end should not notice these affects in most instances.

The G.729A algorithm only uses 8Kbps for its audio path (plus overhead). It therefore dramatically reduces the amount of network bandwidth required to extend multiple telephones. It also provides excellent voice quality to all parties involved in a conversation. However, this algorithm is designed to optimize audio in the frequency range of the human voice. Tones outside of that range may sound muffled. Also, listening to audio that has already been compressed may sound slightly less clear. Here are some of the affects you may notice with over compressed audio:

1. ‘Hold’ music may sound less clear.

2. Dial tone, DTMF tones, and telephone rings may sound slightly garbled, particularly

on the speakerphone. They still should function properly 100% of the time.

3. May experience some minor echo and reduced audio clarity when calling some cell

phones. They often already compress audio.

4. May hear some echo and notice minor delay in the conversation if calling

internationally. This is caused by the delay in providing compressed audio and the fact that calling internationally may already introduce some delay.

If you are experiencing any of these problems and feel that it is not presenting you with adequate voice quality, we recommend using the ADPCM32 or G.711 voice compression method. While it requires more network bandwidth, it uses less voice compression and therefore minimizes the chances that any of these effects ever occur.

Page 83

IP Dual Port PBXgateway and Remote System Administrator’s Guide

It is important to know the following:

5. The type of audio problem; for example: echo, broken or choppy audio, lost calls, etc.

6. When does the problem occur?

a) All calls?

b) Internal calls only?

c) External calls only

d) Intermittently some external calls?

7. Do all users experience the problem?

Echo Problems

Understanding and Correcting Echo Problems

The PBXgateway and Remote employ the industry standard G.165 echo canceller with some proprietary improvements to help eliminate or reduce echo even further. However, it is not possible to cancel all instances of echo 100% of the time. It should be noted that echo perceived by extended PBX users will not be perceived by the party on the other end of the call.

Remote Impact on Echo

Because the Remotes deal exclusively with digital audio on the line side of a PBX, they cannot cause any echo. However, if you experience any echo from your connection to the PSTN (Public Switched Telephony Network), the Remote application could make it noticeable because of increased delay in the audio path. For example, if echo occurs on a line after only a few milliseconds, your ear cannot detect the echo. However, if the echo occurs after 100, 50, or even 20 milliseconds, your ear will likely detect the problem. The G.165 echo canceller can cancel echo only up to certain limitations.

If you experience echo on all external calls, you probably have a problem with your PSTN

trunk lines. Most likely they are analog, and those analog lines are generating a great deal of echo when interfacing with your PBX. Non-extended PBX telephones may not perceive

the echo, due to the fact that echo without delay does not sound like echo.

If you have a noticeable echo problem, you should look into the following:

Cause:

The most common causes of consistent echo on all external calls are analog trunk lines that are out of specification, or a problem with the termination within the PBX. Most commonly there is an impedance mismatch between the analog line and your PBX. Also, the db level of the analog circuit may be too high. Analog circuits that are “hot” are a common cause of echo. Again, that echo may not be perceived on non extended telephones, but that is only because there is no delay.

Possible solution:

If you have analog lines, you should consult your local telephone company and ask for the exact specifications of that line. They may need to go onsite to measure the characteristics of your analog circuits. If you only experience echo occasionally on external calls, your system is probably fine. The echo probably only occurs when calling to or receiving calls from a party that is using:

à analog lines

à a cell telephone

à analog trunks on their telephone system. In this case there is little you can do.

The echo canceller included with the Remotes will usually cancel this echo after a second or two, but occasionally the echo goes beyond its capabilities. However, it should be noted that the party on the other end of the call will not experience this

Page 84

IP Dual Port PBXgateway and Remote System Administrator’s Guide

echo. If you experience a slight echo on all external calls, but it goes away after a second or two, that is normal with analog trunk lines. If you have analog trunks on your PBX, the echo canceller frequently takes a second or two to detect levels of what is echo and what is voice, and then it starts to cancel the echo. The only way to eliminate that situation is to replace your analog trunks with digital trunk lines.

12 FILE MANAGEMENT AND SYSTEM

UPGRADES

Flash Files

The PBXgateway and Remote contain a flash file system to store basic configuration files, the actual firmware and the instructions necessary for starting the units. The flash memory system retains stored data even with no external power applied.

Access to the flash file system is gained using a PC (FTP or Telnet access via LAN). FTP must be enabled, if that is the method you are using, and an administrator’s password should be configured, to control access.

Firmware images stored in the flash file system are saved with extension “.mab.” These files use binary format.

Configuration files stored in the flash file system are saved with “.swt” extensions for the PBXgateway and “.rem” extensions for Remote. All changes you make to the configuration must be saved to the flash file to be applied. The MI prompts you to save changes when necessary.

Call Back files stored in the flash file system are saved with the “.cbk” extension. They contain specific information for the PBXgateway and Remote boot process (IP addressing, active configuration file, firmware for boot). The PBXgateway saves “.cbk” files to allow it to contact remote users that are currently disconnected. This file is also used for Remote Login capabilities.

Configuration File Management

Changing the Active Configuration File

When the PBXgateway or Remote is powered-up, the flash file system loads a configuration file – “.rem” (Remote) or “.swt” (PBXgateway) – which contains all parameters necessary for operation. You may change this “.rem” or “.swt” file so that a different set of parameters loads.

The default configuration file shipped with the units is “runtime.rem” or “runtime.swt.” To change this go to Gateway (Remote) ->Utilities->Upgrade->Config File. Select an existing “.rem” (Remote) or “.swt” (Gateway) file from the list displayed. The display reads “Change Configuration file to …..” Enter [Y]es or [N]o. Assuming you type “[Y]es” to change the configuration file, you are prompted to reboot.

This change will not take effect without a reboot. All changes made to the PBXgateway or Remote parameters will be saved to the file you selected.

Page 92

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Edit Non-active Configuration Files

The PBXgateway and Remote can be used in different applications requiring different parameters. You may need to set up separate configuration files to accommodate custom parameters for each application.

The ability to modify any non-active configuration file enables you to quickly set up new units based on existing configuration parameters.

To edit the “active” configuration file, use the “Configuration” menu. Go to Gateway (Remote) ->Utilities->File->Edit Config

 Type “r” for a Remote file or “g” for a Gateway file.

 Select a configuration file from those available files. Press Enter.

 Modify the parameters as required.

 Select “save” and press Enter to save changes.

 A message is displayed asking you to confirm that you want to save your changes to

the file you selected earlier. Type “[Y]es” to save the changes to that file, “[N]o” to discard your changes or “[S]pecify” to specify a different file name

Creating a New Configuration File

To create a new configuration file go to Gateway->Utilities->File->Edit Config.

 Type “r” for a new Remote file or “g” for a new Gateway file.

 Select <new file> from the list.

 Type a name for the new file. Do not add an extension – that is added automatically.

Press Enter.

 File names must be a maximum of 12 characters.

 Modify parameters as required.

 Select “save” and press Enter to save changes.

 A message is displayed asking you to confirm that you want to save your changes to

the file you selected earlier. Type “[Y]es” to save the changes to that file, “[N]o” to discard your changes or “[S]pecify” to specify a different file name

Upgrading the Software

The upgrade process involves three phases. These should be executed in the following order:

1. File Management. This phase includes:

a) Examining the flash file system

b) Saving an active image file as the default

c) Deleting outdated files

d) Querying the flash file system

e) Optimizing the flash file system

2. File Upload

3. File Upgrade

The PBXgateway and Remote units use image files with the “*.mab” extensions.

File Management

Examining the Flash File System

This procedure determines how many image files are on the flash file system. Path: Gateway (Remote) ->Utilities->Upgrade->Image List

Figure 48: Image List

If “default.mab” is the only file displayed in the list, go to Optimizing the Flash File System

on the next page. Otherwise follow the steps to save the active image file as the default.

Page 94

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Saving the Active Image File as the Default

Saving the active image file as the default:

1. Deletes the existing “default.mab” file on the unit

2. Renames the image that is currently live to default.mab

3. A copy of the current live image remains on the unit after the upgrade is complete

4. If the currently live image is “default.mab” the message “Currently running default

image” is displayed

This process requires the system to be rebooted and this will cause active phones to be taken out of service for a few minutes.

Path: Gateway (Remote) ->Utilities->Upgrade->Default Image

Type “[Y]es” to make the changes specified and reboot.

Figure 49: Default Image

Querying Flash File System

Before loading your new image file into the Flash File System, ensure that there is enough free memory space for it. If the free space is less than 3,000,000 bytes, you must delete files which are not in used by the system (see

Path: Gateway->Utilities->Upgrade->Free Space

Figure 50: Free Space

Deleting Outdated Files on the next page).

Page 95

IP Dual Port PBXgateway and Remote System Administrator’s Guide

Deleting Outdated Files

You must delete all “.mab” files to ensure there is room for the new update file. Path: Gateway->Utilities->Upgrade->Delete

All files not in use are listed – this does not include “default.mab” or the active image file. If these are the only files, a message is displayed stating that all files are in use.

Select a file to delete and press Enter. Type “[Y]es” to confirm that you want to delete the file.

Optimizing the Flash File System

Optimizing speeds up the subsequent file upload. Path: Gateway (Remote) ->Utilities->Upgrade->Optimize

Do not optimize the flash file system when the unit is active. If the flash file is optimized while the unit is being used it may cause the flash file to become corrupt and render the units unusable.

Type “[Y]es” to optimize the flash file system.
