CHAPTER

The Cisco VG30D Voice Gateway

The Cisco VG30D Voice Gateway is a dual-port ISDN unit that is designed to perform signalling and service reconciliation between two unlike ISDN signalling systems.

It typically gets deployed to attach the following:

OL-19276-01

Cisco VG30D Voice Gateway User Guide

1-1

The Cisco VG30D Voice Gateway

• A QSIG (or DPNSS) PBX to a DPNSS (or QSIG) network, or

• A number of DPNSS PBXs to a QSIG or Q.931 backbone network (VoIP or ATM, for example), or

• A DPNSS PBX to a Q.931-based Public ISDN service (such as ISDN 30e).

When you are attaching a QSIG (or DPNSS) PBX to a DPNSS (or QSIG) network, Cisco VG30D Voice Gateway provides seamless service interworking between the attached PBX and other PBXs in the network, including inter-operation of most of the commonly used services.

Cisco VG30D Voice Gateway facilitates basic call interworking, including simple services such as calling and connected identity when attaching a number of DPNSS PBXs to a QSIG or Q.931 backbone network, or a DPNSS PBX to a Q.931-based Public ISDN service.

In addition, when attaching a number of DPNSS PBXs to a QSIG backbone network, the, Cisco VG30D Voice Gateway can transport DPNSS signalling across the network and deliver it practically transparently through a similar InterChange unit to a remote DPNSS PBX. In this mode, all DPNSS Supplementary Services get supported apart from some link-specific Traffic Channel maintenance services.

Cisco VG30D Voice Gateway supports 2 E1 Primary Rate [2 Mbit/s (30B + D) Common Channel Signalling] interfaces; providing a single Primary Rate conversion. The unit has been designed to be installed on a 19-inch rack. It is particularly suited for use in Customer Premises Environments (CPE) to interface equipment into Virtual Private Networks.

Figure 1-1 shows DPNSS PBXs interconnected across a QSIG network. In this configuration, the

combination of InterChange units and the network behave as a single DPNSS transit node and transports DPNSS supplementary signalling.

Conversions operate on the common signalling channel only. Bearer circuits get passed directly through the unit. You can configure each protocol support to meet specific application needs.

You can configure the Virtual Private Network protocol support to operate into sub-equipped ISDN trunks, which allows the user to maximise the benefits of the advantageous Primary Rate ISDN tariffs now that are being offered by some PTOs.

The Cisco VG30D Voice Gateway also provides some additional facilities:

• The ability to perform diversions on behalf of the PBX

• Support for the Q.932 redirecting number element for diversion

• Custom configuration for Cisco Unified Communications Manager and other PBXs

• The ability to display DPNSS Message Waiting Indications on telephones that are controlled by

The two amber Port LEDs are labelled P1 and P2. Together with the STATUS LEDs, they indicate unit status. When the unit is operating normally and all is well, these LEDs turn on and off every few seconds with all STATUS LEDs off.

When a problem exists, the Port LEDs will show the problem’s location (P1 or P2, or if both P1 and P2 are lit, a major alarm exists). The STATUS LEDs will then indicate the problem. If more than one port has a problem, they will be shown in a cycle of 5 seconds each.

Power

The Power LED has two functions. When power is applied, it comes on amber to indicate that the unit is in self-test mode. When the self-test satisfactorily completes, it changes to green to indicate that the unit is functioning correctly.

Back Panel Equipment

Each port has three connectors. The two BNC connectors, which are 75-ohm unbalanced, are marked Rx and Tx. The RJ45 connector is 120-ohm balanced. Ensure the Impedance Switch is set to the correct impedance. You can configure parameters for each port using the Gateway Management Interface on a Web browser.

The Craft Port exists primarily to enable a serial connection to a dumb terminal or a terminal emulation application on a computer that is running RS-232 at 9600 baud, 8 bit, 1 stop bit, and no parity.

If required, you can connect the Cisco VG30D Voice Gateway Alarm Port to an alarm signal detector before powering on the unit.

Switches

Power On/Off

The power On/Off switch (I / O) is adjacent to the mains connector.

Caution Before connecting any cables or changing any switches, power off the Cisco VG30D Voice Gateway.

POST

You must set the Power On Self Test (POST) switch in the POST position before powering on the Cisco VG30D Voice Gateway unit. Only Cisco Systems, Inc., engineers use the Factory position.

Impedance Switches

This allows the selection of either 75-ohm or 120-ohm impedance for the SCN ports. Use 75 ohms for coaxial BNC connection (BNC position), and 120 ohms for UTP RJ45 connectivity (RJ45 position).

Caution Make this selection before power is applied to the unit.

Craft Switch

Use the Craft switch to switch between serial connection for initialising the Cisco VG30D Voice Gateway and Factory Engineering management. By default, the switch should stay set to Craft.

Power On Self Test and IP Address Setup

On power ON of the Cisco VG30D Voice Gateway, the unit will perform a self-test. The Power LED on the front panel shows amber, and the four STATUS LEDs come on and go off (in sequence from left to right) to indicate that the unit is performing the self-test. These tests check the correct operation of the hardware and start the operational software. This process should complete in less than 1 minute.

Successful Self-Test

When all the tests complete successfully and the software is operational, the Power LED changes colour from amber to green. Approximately 30 seconds later, you can log in to the web-based Gateway Management Interface.

The Cisco VG30D Voice Gateway has been configured with the default IP address of 192.168.1.1 and sub-net mask 255.255.255.0.

Proceed as follows:

Step 1 Connect the ethernet port of the Cisco VG30D Voice Gateway directly to the ethernet port of a computer.

Step 2 Open a web browser and enter 192.168.1.1 directly into the IP address bar.

• Select or deselect Clear on Establish

If checked, the Cisco VG30D Voice Gateway will send a CRM on each LAP as it is established.

• Channel Allocation - Low to High / High to Low

This dictates whether channels get allocated to calls starting at the highest or the lowest enabled channel.

Advanced Settings

Available settings include the following:

• Proxy Diversion Service: If service is enabled and a call from the QSIG network to the DPNSS

network is diverted, the Cisco VG30D Voice Gateway will intervene to ensure that the diversion takes place. If service is disabled, calls from the QSIG network that encounter diversion at a DPNSS PBX are likely to fail. This setting does not affect calls from DPNSS, either to QSIG or transparently over QSIG to other DPNSS extensions.

You can configure diversion service to act on behalf of all calls (All), a specific dialed number (Exact), calls matching a part of the dialed number (Match) or calls that do not match (No Match) a given part of a dialed number.

• Proxy Divert Address Filter: The filter represents the digits against which the dialed number is

matched, if the Proxy Diversion Service is set to Exact, Match or No Match.

• Operator Recall Timeout: This setting only applies if Proxy Diversion is enabled. If a call is

diverted by an Operator in the DPNSS network to a phone in the QSIG network, the phone to which it has been diverted will ring for the number of seconds that is configured and then will revert to the operator (unless answered). If the Operator Recall Timeout is disabled, the call will continue ringing at the QSIG extension.

• Enable ISDX VMS Emulation: Checking this setting allows extensions on QSIG PBXs to be

integrated into a Voice Mail System (VMS) that is hosted on an ISDX PBX.

• ISDX VMS Diversion on No-reply Timer: See DPNSS Message Waiting Implementations and

ISDX Voice Messaging Systems.

• Default ISDX VMS Number: See DPNSS Message Waiting Implementations and ISDX Voice

The Calling Party Category ‘Operator’ match string, Calling Party Category ‘PSTN’ match string, Calling Party Category ‘ISDN’ match string and the Calling Party Category ‘Decadic’ match string fields define the strings to be matched for each type CPC that can be generated in this

way.

• Segment long ISRMs: When checked, this field allows the Cisco VG30D Voice Gateway to

generate ISRM(i) - SSRM(c) sequences where the incoming Q.931 Setup message that indicates sending complete would result in a generated ISRM(c) that is exceeding the maximum DPNSS PDU size.

• Incoming Channel Mapping: If setting is configured to Fixed, the channel that is used by the

incoming call must get used for the outgoing call. If setting is configured to Switched, a different channel may get negotiated in the outgoing Q.931 call, and the Cisco VG30D Voice Gateway will switch the bearer channel internally.

• Transparent Transport Service Support: This setting enables the generation of information that

is necessary to transport the original DPNSS messaging transparently across a QSIG network.

• Re-attempt Transparency after transfer: If the box is checked, the Cisco VG30D Voice Gateway

• Enable Diversion Service: This option allows the Cisco VG30D Voice Gateway to operate

Diversion Services.

• Diversion Validation response time: This option specifies the time (in seconds) that the Cisco

VG30D Voice Gateway will wait before autonomously generating a positive response to Diversion Validation Request from the DPNSS PBX or network.

• Enable Loop Avoidance Insertion: If option is enabled, the Cisco VG30D Voice Gateway will

insert a loop avoidance (LA) string containing the Number of Further Transits value in the outgoing signalling.

• Loop Avoidance mapping: If option is set to Simple the DPNSS LA value gets mapped directly to

the Q.931 transit Counter, but if option is set to Enhanced it gets treated as though it is passing through a transit PBX before it is forwarded.

• Include Loop Avoidance in CRM: If the treatment of the LA results in the call clearing and this is

checked, the LA string will get included in the Clear Request Message that is generated by the Cisco VG30D Voice Gateway.

• En-bloc Call Forward Digit Count: You can use this option to turn overlap dialed DPNSS calls

into en-bloc calls. When the specified number of digits has been received, the call gets forwarded en-bloc. Be aware that this is only appropriate for networks with fixed-length dial plans.

• En-bloc Call Forward Timeout: This option acts as an interdigit timer that will forward the call

when it expires. It restarts as each digit arrives. This option proves suitable for networks with variable-length dial plans, but introduces a post dial delay.

• Default Destination Address: You can use this field to provide a default destination address when

no dialed digits are received from the Q.931/QSIG PBX or network.

• Number of leading Destination Digits to strip: You can use the Cisco VG30D Voice Gateway to

strip leading digits such as node numbers from the dialed number, if required.

• Enable Service Spoofing: If this option is enabled, Transfer Hold and Diversion Validation Service

may get spoofed on behalf of the Q.931 network. (The services must also be enabled.)

• Three Party Working EEM Spoofing: When this option is enabled, the Cisco VG30D Voice

Gateway will generate EEM messages to resolve interaction between spoofed Transfer and ROP services.

response to a Service message with global call reference that is being received. The Cisco VG30D Voice Gateway will respond with Service Ack message if option is enabled or a Status message with cause of Message Not Implemented if disabled.

• Call Reference Length: Setting allows the Cisco VG30D Voice Gateway to accept one-octet or

two-octet Call references. If Single is selected, the Cisco VG30D Voice Gateway will only send and receive one octet length call references. If Double is selected, only call references that are two octets in length will be deemed valid. When Both is selected, the Cisco VG30D Voice Gateway will accept either length for incoming calls and generate two-octet Call References on outgoing calls.

• Send Sending Complete Element: Unchecking the box allows the Sending Complete Information

Element to be suppressed in outgoing en-bloc calls.

• Send Connected Number Element: Unchecking the box allows the Connected Number

Information Element to be suppressed in outgoing Connect messages.

• Enable Calling Line Id: Unchecking the box allows the Calling Party Number Information Element

to be suppressed in outgoing messages.

• Connected Number Element Identifier: This setting allows the encoding to be selected according

to the connected network requirements. 76/0x0C provides compatibility with older TR41449 implementations that use that coding.

• Include Octet 3a in Connected Number: Checking this box will enable the transmission of

Presentation and Screening Indicators in Connected Number Information Elements.

• Support Progress Indicator in Call Proc. and Disconnect: Checking this box will enable any

available progress information to be sent in Call Proceeding and Disconnect messages.

Access Control

Access Control settings allow the user passwords and Non-Use Timeout Period to be set. Alphanumeric characters, with the exception of space, are legal for passwords. The Non-Use Timeout Period specifies the time that is allowed for a user to be logged into the Gateway Management Interface without actively using it before being automatically logged out when another user attempts to log in. It may be set from 3 to 15 minutes.

Software Upgrade

The Cisco VG30D Voice Gateway gets supplied with an embedded default operational software. It can only get upgraded with software that is of the same type as the embedded software.

Software Upgrade allows a new version of the software application to be downloaded to the Cisco VG30D Voice Gateway by using an FTP server.

The IP address of the FTP server, a User Name and a Password are all required to access the FTP server. The directory and filename of the new application on the FTP server is also required. Selecting Upgrade will download the new application to the Cisco VG30D Voice Gateway.

This new application will overwrite an existing previously downloaded application but not the default application. The new application will run next time the Cisco VG30D Voice Gateway is reset, but only if the new software has been selected by using the Software Selection facility. Instructions on installing the software version will be provided with the new software.

Configuration Backups

Be aware that configuration backups are release specific. After the software upgrade completes successfully and is operational on the unit, a new configuration backup should be saved.

The procedure is as follows:

Cisco VG30D Voice Gateway User Guide

4-12

OL-19276-01

Chapter 4 Management and Configuration

Step 1 Upgrade to the new version of the software.

Step 2 Select the version of the software to run next time the unit is restarted.

Step 3 Restart the Cisco VG30D Voice Gateway unit. The configuration that is stored on the unit automatically

gets loaded into the new version of software.

Step 4 Perform a Back Up Configuration as described in the Gateway section. A configuration backup file that

is compatible with the newly activated software gets produced.

Note You cannot restore a backed-up configuration file to a system that is running a different version of

software to that under which the backup file was saved.

Note Cisco Systems, Inc., recommends that each backup configuration file be given a unique name that

includes the software release number. This will ensure that, if the configuration backup files are stored in a central location, a new backup file does not overwrite an existing file that may be required for a different location.

Diagnostics

The Gateway Management Interface produces logs for System, Major Alarm, and Port Errors and statistics for Port Errors and Calls.

You can print information in management diagnostics screens. As an alternative, by using the Select All, Copy and Paste facilities in the Web browser, you can export the information in ASCII text to other applications.

Note If the system is set to Factory Defaults and the Cisco VG30D Voice Gateway is rebooted, all the logs

will get cleared, and the information other than the System Log will get lost.

System Details

System Log

System Details provide hardware and software information for the Cisco VG30D Voice Gateway unit. You will need to be able to refer to this information when you communicate with the Helpdesk for support.

The system log is created and updated dynamically. It records the date and time of certain system events, including system crashes, automatic reboots, and manual restarts. Successful and attempted logins get recorded.

Table 5-1 defines the various events that may get generated by the Cisco VG30D Voice Gateway and get

written to the System Log during operation. Event classifications indicate their seriousness. Events get classified at the following four levels:

• Critical

• Major

• Minor

• Informational.

Critical indicates an event that has caused the Cisco VG30D Voice Gateway to restart. Always report these events your supplier. Error codes for critical events include 1, 2, 303 and 601.

Q.931/DPNSS Conversion Configuration

Q.931 Port 1 Configuration

Basic Configuration

The default setting of the Q.931 port at Layer 2 (Q.921) specifies USER End. You must configure this with inverse orientation to the attached equipment/network.

As the default, the Cisco VG30D Voice Gateway causes a Layer 2 RESET on recovery after physical layer failures. This causes all calls to be cleared when a Channel 0 fault is notified. Alternatively, you can configure the Cisco VG30D Voice Gateway to ignore Layer 1 fault indications and rely on periodic Layer 2 status polling to detect link problems.

Protocol Orientation

The Layer 3 orientation gets set automatically according to the profile and Layer 2 orientation.

Action on Link Layer RESET

As the default, the Cisco VG30D Voice Gateway takes action to validate Q.931 call status for all fully active calls on notification of a Link Layer RESET. Calls only get cleared if they are not fully set up or a discrepancy exists in call state.

You can configure this to cause all calls to be cleared when a Layer 2 fault is notified, regardless of their state. If the glitch sensitivity has been reduced in Channel 0 configuration, you may want to clear calls after a fault is finally notified. Status validation should be adequate in most cases.

Overlap Signalling Support

If the Q.931 network/equipment supports overlap signalling, enable it by selecting Incoming for overlap from Q.931, Outgoing for overlap towards Q.931, or Both Ways.

For transparent signalling, set overlap signalling to Both Ways.

OL-19276-01

Cisco VG30D Voice Gateway User Guide

6-1

Q.931/DPNSS Conversion Configuration

DPNSS Networks in the UK typically support overlap signalling for all calls. You can make the Cisco VG30D Voice Gateway block up incoming digits from DPNSS by setting this option to None or Incoming. In isolated cases, it may be appropriate to turn on preemptive call forwarding in the Q.931 stack. This action very rarely is required. However, if it is needed, it operates as described in

Port 2 Configuration.

If the En-bloc Call Forwarding Timeout in Advanced Configuration is set to 0, the normal Q.931 T302 timer runs to clear incomplete calls after 15 seconds without dialling activity.

Advanced Configuration

Q.931 Profile Selection

You can profile the Q.931 port to conform to ETSI, AT&T (TR 41449), Euro-ISDN or QSIG definitions. The default is QSIG.

For DPNSS/QSIG transparency the Layer 3 protocol Profile must get set to QSIG.

The ETSI profile is based on ETSI Specification ETS 300 102-1,). The Euro-ISDN profile is based on the same specification, with amendments applied in ETSI specification ETS 300 102-1/A2. The differences between the ETSI and Euro-ISDN profiles relate to the content of messages. No changes occur to call setup and clear-down.

Cisco Systems, Inc., recommends that Euro-ISDN profile be used when you are not configuring the Cisco VG30D Voice Gateway for transparency, irrespective of a requirement for TBR-4 compliancy. Choose the ETSI profile only where TBR-4 compliancy is not required and where the Euro-ISDN profile is deemed to be incorrect. Where TBR-4 compliance is required, you must choose the Euro-ISDN profile.

Each profile sets particular defaults, appropriate to the standard definition, but these values can then be overridden by specific action, which allows customisation of the interface to non-standard equipment implementations. The rest of this section discusses these override options.

Chapter 6 Conversions and Transparency

DPNSS

Services Configuration

Default Destination Address

When you are operating into a DPNSS-based public network, which may address to the subscriber number only with no private network extension number, you must ensure that a private network extension number is supplied. This enables non-DDI calls to get directed to a sensible destination such as the common operator. Normally, this would occur in the Q.931 PBX. However, in Cisco VG30D Voice Gateway AT&T and QSIG implementations, it can get configured to be supplied by the Converter.

By default, non-DDI calls get a Q.931/QSIG Called Party Address of 0 as the ubiquitous operator number. You can customize this forwarding address by configuring the appropriate private network number, including any node address, as the Default Destination Address.

You do not need the Default Destination Address for transparency.

DPNSS Port 2 Configuration

Basic Configuration

The default setting of Level 2 for the DPNSS port specifies A end. Ensure that this is configured with inverse orientation to the attached equipment/network.

Sub-Configured Links

You can configure DPNSS channels individually for operational service (that is, the DPNSS link can be sub-configured). Q.931 calls will only get generated or accepted on those channels for which an equivalent DPNSS channel is configured.

Contention (Glare) Resolution

When all channels on the associated DPNSS link are configured as X, the DPNSS equipment, being the Y end, gives precedence to incoming calls, so most channel contention problems get resolved in the

DPNSS network.

Similarly, it is advantageous though not mandatory, if Cisco VG30D Voice Gateway can be configured as the “Network” end of the Q.931 link. This is because this gives it precedence for calls over the attached “User” end equipment.

Reduce channel contention (glare) problems further by influencing the choice of alternative channel. Select High to Low or Low to High as the Channel Allocation option, when you are configuring the DPNSS stack. High to Low causes the highest free channel to be selected, and Low to High causes the lowest free channel to be selected.

Q.931/DPNSS Conversion Configuration

Services Configuration

Default Private Network Number

When you are operating into a Q.931-based public network, which may address calls to the subscriber number only, with no private network extension number, you must ensure that a private network extension number is supplied, so that non-DDI calls get directed to a sensible destination such as the common operator. Normally, this would be done in the DPNSS PBX, but you can configure it to be supplied by the converter.

By default, non-DDI calls are receive a DPNSS Called Line Identity of 0, as the ubiquitous operator number. You can customize this forwarding address by configuring the appropriate private network number, including any node address, as the Default Destination Address.

You do not need the Default Private Network Number for transparency.

Destination Address Editing

You can edit the destination address that is associated with calls from DPNSS before the address passes out to Q.931, by discarding up to three leading digits. For example, a leading 9 inserted to cause the call to be routed to an outgoing public trunk can get stripped before the call passes to the ISDN by setting Number of Destination Digits to Strip to 1.

No requirement exists for Address Editing when you are using transparency.

DPNSS/QSIG Transparency Options Configuration

Preemptive Call Forwarding

Depending on whether the Q.931 implementation to which the Cisco VG30D Voice Gateway is interfaced fully supports overlap signalling, you may need to configure the En-bloc Call Forward Timeout and/or En-bloc Call Forward Digit Count parameters in the DPNSS stacks.

The converter uses these call forwarding parameters when overlap signalling is encountered from DPNSS to Q.931. The converter uses these parameters to recognise when no more digits are forthcoming and to indicate address completion and speed call setup. You should include any edited-out digits in the count of address digits after which the call must get forwarded. They are not normally required when you are interfacing into a public network because the network preempts such contrivances.

In both cases, a value 0 turns the address-phase termination function off. The En-bloc Call Forward Timeout represents an interdigit timer.

You do not need this feature for transparent signalling.

DPNSS/QSIG Transparency Options Configuration

Transparent operation between Cisco VG30D Voice Gateway systems across a QSIG or DPNSS network does get supported.

DPNSS Message Waiting Implementations

Message Waiting service does not get defined in DPNSS. Therefore, it is not always possible to find an interworking service match. Various manufacturers define proprietary signalling for turning ON and OFF Message Waiting indicators, or use the DPNSS Call Back Messaging service for this purpose. To configure the Cisco VG30D Voice Gateway to interwork QSIG Message Waiting with some common PBXs, go to Configuration / Inter-Working.

ISDX Voice Messaging Systems

Siemens implemented proprietary extensions to DPNSS Diversion to achieve better integration with their voice messaging servers (VMSs). You can configure the Cisco VG30D Voice Gateway to attempt to interwork these extensions with the QSIG Call Forwarding service. However, in some cases, interworking is partial.

In iSDX/Realitis networks where a single VMS, ensure the Cisco VG30D Voice Gateway is configured with the SPIDG address (the Logical Extension Identifier for the VMS hunt group - sometimes called the RFD address). This is unnecessary in multiple VMS networks, where the PBXs assert the required number explicitly in their RFD signalling. ISDX VMS parameters get set up on the DPNSS Advanced page.

Cisco VG30D Voice Gateway units have further advanced configuration options. Your support organisation may direct you to use these options to resolve specific VMS interworking problems. The default configuration settings remain correct for most networks.

Name Mapping

Cisco VG30D Voice Gateway units support both the Q.931 display element to transfer name information (in either direction) and the QSIG Name Identification service options.

The most prevalent use of the display element option is by media gateway (DE30+) cards that are attached to the Cisco Unified Communications Manager, supporting Q.931 protocol (not QSIG).

Route Optimisation Options

The DPNSS Services Configuration window provides two additional options when DPNSS Services / Enable Route Optimisation Service and Q.931 Services / Enable Path Replacement Service are

checked:

• PBX accepts Route Optimisation Invite String

• Restrict Route Optimisation Call Ref. Mapping

Advanced Service Interworking

Use of DPNSS Route Optimisation Invite String

If you selected full interworking. Cisco VG30D Voice Gateway can occasionally persuade the network to achieve more effective call routing by issuing a “ROP-INV” request to the DPNSS PBX. ROP-INV was a late addition to the DPNSS specification, so not all DPNSS PBXs support this request. It can prevent some of those PBXs from achieving correct Route Optimisation. You may need to ask your PBX supplier, or experiment to determine whether your PBX accepts this string.

If the DPNSS PBXs attached through this unit support ROP-INV, then no calls will fail. However, if you are in any doubt about the ability of your DPNSS PBXs to handle ROP-INV, you should not check the box beside PBX accepts Route Optimisation Invite string in DPNSS Services, because correctly operating Route Optimisation without ROP-INV is better than incorrect operation if the PBX does object to the Cisco VG30D Voice Gateway’s use of this signalling.

Restricted Route Optimisation Call Reference Mappings

When the Cisco VG30D Voice Gateway interworks the QSIG Path Replacement Network Feature with DPNSS Route Optimisation, it constructs a DPNSS Call Reference value from the Path Replacement parameters that are provided in QSIG, and vice versa. The service parameter definitions do not always match exactly. This has been rectified only in the most recent DPNSS specification (issue 7), and many PBXs do not implement the upgraded standard.

QSIG Facility Element Encoding

Cisco VG30D Voice Gateway’s QSIG Protocol and Supplementary Services support can comprise any one of three different QSIG definitions:

• The original definition defined by ECMA on behalf of ETSI in 1993 (ETS 300 172 / ETS 300 239

versions 1 & subsequently adopted service specifications).

• The ISO definition, adopted in 1994 (ISO/IEC 11572/11582:1995 & services).

• The ISO-aligned definition adopted by ETSI in 1995 (ETS 300 172/239 versions 3 & services).

OL-19276-01

Cisco VG30D Voice Gateway User Guide

6-7

Advanced Service Interworking

When the Q.931 QSIG protocol profile is selected, the QSIG facility element encoding defaults to ETSI

1995.

To change the facility coding definition manually, you must make changes in two windows as follows:

Step 1 Go to Configuration / Q.931 Services.

Step 2 Set Facility Element Coding Standard to ISO (ISO 1994), ETSI (ETSI = ETSI 1995), or ECMA

(ECMA = ETSI 1993), and click SUBMIT.

Step 3 Go to Configuration / Inter-Working.

Cisco Systems, Inc., suggests that you contact your Q.931 equipment supplier if one or more Supplementary services will not interoperate with its default ETSI (1995) encoding and you suspect the Q.931 equipment may be operating to an alternative standard. With some PBX equipment, more service capabilities are available with the PBX configured for ECMA (1993) rather than ISO operation.

QSIG Diversion Restriction

Certain DPNSS PBXs enforce an arbitrary constraint that prohibits a network user from diverting the phone to an off-net number (for example, a national mobile number). In a mixed network that includes such PBXs, the feature permits those QSIG PBXs that are capable of performing “call forward by join” to offer off-net diversion without the diversion request being referred back to and rejected by the DPNSS PBX.

In DPNSS, on determining that a call is being attempted to a phone against which a diversion is registered, the destination PBX signals this to the originating PBX. It should then attempt a new call to the “divert to” number that is identified by the destination PBX. Certain DPNSS PBXs enforce an arbitrary limit on the length of the “divert to” number. If it exceeds that length, the PBX will not attempt to divert the call, and the call fails.

This can be controlled by setting Reject Diversion Request for Numbers Longer than.

Some QSIG PBXs overcome this restriction, without requiring action from the originating DPNSS PBX, by making the diverting leg of the call and joining the new and original call legs. Cisco VG30D Voice Gateway can now get set up to detect the condition (overlong divert-to-number) and change its signalling to trigger the QSIG PBX to take alternative diversion action. Where the length of the divert to number is not excessive, Cisco VG30D Voice Gateway units allow the QSIG diversion request to “interwork” with the DPNSS PBX as normal. automatically, and you can only turn it off by reconfiguring the option.

Using Diversion Restriction

After it is configured, the diversion interception action acts entirely

The diversion restriction problem has been encountered specifically in networks that contain Ericsson MD110 PBXs that are using DPNSS signalling.

Limitations to Diversion Restriction

Diversion Restriction should not be used unless the following conditions are true:

• The originating PBX refuses to implement certain kinds of diversion.

• You are certain that your QSIG PBXs can perform call forward by join.

Note Call forward by join can result in non-optimal bearer paths (trombones). Because of the particular way

in which the path is created, these may not always get optimised by subsequent path replacement requests.

Configuring Diversion Restriction

Changes in diversion behaviour take place by using the Cisco VG30D Voice Gateway Configuration / Q.931 Services window. Set Reject Diversion Requests for Numbers longer than to the maximum length of the number that is permitted, or set to 0 to disable diversion restriction.

Configuring Cisco VG30D Voice Gateway Proxy Services

For most applications the Cisco VG30D Voice Gateway Application windows give adequate control over the services to be proxied by the Cisco VG30D Voice Gateway on behalf of Q.931 equipment, but some more detailed tuning is possible using the Configuration / DPNSS Advanced window.

Proxy Diversion Address Filtering

In particular, you can set an address filter to determine whether the Cisco VG30D Voice Gateway will attempt to make a proxy diversion or will reject the call immediately.

The filter operates by comparing the leading digits of the diverted-to number with a pre-set number. You can configure the Cisco VG30D Voice Gateway to attempt proxy diversion if the diverted-to address digits meet any of the following criteria:

• Match the preset digits up to the length of the pre-set, but the diverted-to address may be longer than

the pre-set (if your network numbering plan uses a node numbering strategy, this allows you to confine proxy diversions to a single node or group of nodes. For example you can confine the diversions to occur within the DPNSS network only);

• Fail to match the preset digit string, up to the length of that string (This is the inverse of the previous

option. If your network numbering plan uses a node numbering strategy, it allows you to perform proxy diversions except to a single node or group of nodes. For example this option allows you to exclude diversions to the Q.931 equipment);

• Match the preset exactly, including having the same number of digits as the preset (This allows you

to permit only one proxy diversion address. For example, this option allows you to permit configure the address of a voice mail system.);

• Are any value (That is, the Cisco VG30D Voice Gateway will attempt to proxy all diversion

requests).

The address filter gets set from the Configuration/DPNSS Advanced window.

Operator Recall Timeout

Operator Recall Timeout applies to calls incoming to the DPNSS operator that have been transferred to a phone in the Q931 network. It ensures that, if the wanted party does not answer in a predefined period, the call gets returned to the operator. If, after speaking to the operator the caller wants to hold, the operator may reconnect the caller to the wanted number with a single key press. Otherwise, the call may get redirected to a different number

The Configuration/DPNSS Advanced page allows the user to set the Operator Recall Timeout to the period to wait before returning the call to the operator.

Note This configuration will not in itself enable Operator Redirection. This service only gets provided when

Proxy Diversion Service is enabled and the Operator Recall Timeout is not set to zero.

Service Spoofing

Further service spoofing may get enabled or disabled within the Cisco VG30D Voice Gateway. Service spoofing covers the following areas:

• Automatic acknowledgement of DPNSS Diversion Validation requests

• Returning “last known” party number as update information to DPNSS if a call to or from a Q.931

To enable / disable service spoofing, open the Configuration/DPNSS Services window. To enable Diversion Validation spoofing, check the Enable Service Spoofing box in the Virtual Calls column. To enable the spoofing of the last known number, check the Enable Service Spoofing box in the Real Calls column. Ensure the Enable Three Party Working box also is checked.

SCN Clock Synchronisation

Incorrect clock synchronisation on the SCN side of the Cisco VG30D Voice Gateway can cause severe problems with modem and fax quality, and lesser problems with voice quality. Calls may also get dropped.

Ensure the clock is set by using the Gateway Management Interface. Go to Configuration / Gateway / Set PCM Clock Source. Select whichever port can provide a network-provided clock. It will synchronise to the source that is selected if a valid clock is present or synchronise to the other port if a clock is not present. If you are unable to synchronise to either port, the Cisco VG30D Voice Gateway internal source will get used.

The Cisco VG30D Voice Gateway does not get specified to have its own very high resolution clock tied to the National Public Network frequency, nor does it get specified to accept a Kilostream clock input.

Introduction

CHAPTER

Fault Determination

This chapter on Troubleshooting has sections that cover the following:

• Power-On Problems

• Management Interface Problems

• Operational Problems

• Diagnostic Procedures

• Browser Interface Problems

These sections are written for a user attending a new or failed installation. Flow charts outline the initial diagnostic procedure and direct the user to specific procedures for the recommended recovery action.

These sections also provide an indication of the level to which remote diagnosis may assist.

Be aware that, when you are performing an installation, cabling problems are common.

The section on Port Failure Alarms shows how to diagnose the majority of these alarms by using the information that is shown on the status display.

Power-On Problems

When a Cisco VG30D Voice Gateway is powered on, it performs a series of self-tests to ensure that the hardware is functioning correctly. Normal operation of the module resumes only if all tests are successful.

The four STATUS LEDs and the Power LED on the front panel indicate the progress of tests.

If nothing is displayed, follow the Power Supply diagnosis procedure.

Management Interface Problems

You cannot to log in to the Gateway Management Interface if:

• The Gateway IP Address or Subnet Mask are incorrectly set

• Another User is logged in to the Gateway Management Interface

• The last User hasn’t logged out correctly, and the Non-use timeout has not expired

OL-19276-01

Cisco VG30D Voice Gateway User Guide

10-1

Operational Problems

• The Self Test has failed

• Access is attempted from a different LAN segment, and the Default Gateway IP Address has not

been set up in the Cisco VG30D Voice Gateway unit

• A connection was made to the web server before the unit is fully operational. This may result in a

delay in displaying the main window and could also result in question marks appearing in the SCN Status. You can resolve this by refreshing the page or by closing down and then restarting the browser.

Operational Problems

Figure 10-1 shows how to pinpoint a failing piece of equipment or cabling by deduction from local

equipment and Cisco VG30D Voice Gateway alarm relay indications, assuming that the IP network and its diagnostic information are outside the control of the local management system.

Chapter 10 Fault Determination

• An alarm monitor detects that the alarm relay has triggered

• A user advising of lack of service

• An indication of Alarms from connected equipment

• Error status on the LED display

If a fault is indicated in the Cisco VG30D Voice Gateway or the network beyond, you can interrogate for the status of each port if management terminal access is available. Otherwise, examine the status indications on the Cisco VG30D Voice Gateway front panel.

Examine the status LEDs. In the normal operational state, an LED is shown for each in-service port. If this is not the case, follow the checks that are outlined in to the most appropriate of the specific diagnostic procedures that are described in Diagnostic Procedures.

Chapter 10 Fault Determination

Power Supply

Symptoms

No LEDs illuminated.

Diagnostic Actions

Step 1 Check whether there is power to the unit and the unit is switched on.

Step 2 Check for fuse failure in the power feed or on the rear panel of the unit.

Step 3 If you still cannot locate the problem, you must return the Cisco VG30D Voice Gateway unit for repair.

Self Test Failure

Symptoms

The Power LED remains amber for more than 1 minute.

Diagnostic Procedures

Diagnostic action

The hardware self-test failed.

If the BNC cables (75 E1) are connected, power OFF the unit and disconnect the cables. Repeat the test. If the unit successfully completes self-test, the Tx and Rx cables are reversed.

Note The unit will fail self test if the E1 ports are looped back to each other.

Power OFF and connect a dumb terminal (or computer with a terminal emulation program) to the Craft Port and set the Craft Switch to CRAFT Mode. Power ON to reset the unit. The Cisco VG30D Voice Gateway will Self Test again, and the terminal will display any failures. If no Self Test failures exist, but the Power LED remains amber, check that the POST switch has not been left in the Factory setting. If it has, power OFF the unit, switch the POST switch to POST, and power ON the unit. It should now pass and exit Self Test.

If the unit continues to fail the self test, take the following action:

• Contact your second line support engineers for assistance, if needed.

• Return the failed unit for repair, with a note of the errors that were reported to the terminal.

Symptoms

The Power LED remains amber for more than 1 minute, the S2 status LED is blinking and all other status LEDs are off.

Diagnostic action

Check whether the Craft cable is attached to the unit but the other end of the cable is not attached to a dumb terminal (or computer with a terminal emulation program). If this is the case, power OFF the unit, disconnect the cable and then power ON the unit. It should now pass and exit Self Test.

Alternatively, the IP addresses and sub-net masks may not have been configured.

OL-19276-01

Cisco VG30D Voice Gateway User Guide

10-5

Diagnostic Procedures

Power OFF and connect a dumb terminal (or computer with a terminal emulation program) to the Craft Port and set the Craft Switch to CRAFT Mode. Power ON to reset the unit. The Cisco VG30D Voice Gateway will start Self-Test again and request the IP addresses and sub-net masks if they have not already been set. After Power On Self-Test runs to completion, power cycle the Gateway unit.

Port Failure Alarm

Symptoms

When when a Port Failure alarm exists, it is indicated by either P1 or P2 LEDs showing amber.

Note If both P1 and P2 LEDs show amber at the same time, this indicates that an un-acknowledge

Diagnostic Procedures

Call Failures

Chapter 10 Fault Determination

Symptom

The STATUS LEDs show no faults, but no calls can be made. No indication of failure comes from attached equipment.

Diagnostic Action

If the attached equipment is indicating a problem, you may be able to diagnose the fault by referring to that equipment’s troubleshooting documentation.

Log in to the Cisco VG30D Voice Gateway by using a web browser. Check that the Diagnostic Overview window shows no problems.

You can also monitor the Cisco VG30D Voice Gateway's ports in turn by using a Primary Rate signalling protocol analyser. Check that calls are being received into the equipment and are being passed on to the associated port. If not, and the cause is not obvious from inspection of the analyser diagnostics, contact your support organisation for further guidance.

Symptom

Calls get dropped unexpectedly while in progress.

Diagnostic Action:

The commonest cause is transient transmission problems on the network-side connections. Check whether errors are occurring on either port. Alternatively, request that the network provider run checks on the connection.

Symptom

Higher than expected levels of unsuccessful call attempts.

Diagnostic Action:

In a DPNSS environment some or all channels may be incorrectly configured at Layer 3 (set to X or to Y at both ends), which causes failure to resolve channel contention correctly. Therefore, the

configuration must be reviewed.

Symptom

DPNSS transparency is not achieved across a Q.931 network.

Diagnostic Action

The switching elements in Q.931 network do not support the Generic Functional Protocol, or do not have this function enabled. Therefore, the configuration must be reviewed.

Symptom

DPNSS services requiring virtual calls do not work.

Diagnostic Action

Switching elements in the Q.931 network do not support non-call-associated signalling or do not have this function enabled. Therefore, the configuration must be reviewed.

Chapter 10 Fault Determination

Fatal Errors

Diagnostic Procedures

Symptom

Unexpected restart; calls in progress may get lost, but the unit recovers within a couple of minutes. On examination the unit appears to be functioning normally.

Cause

The software has detected an error that it cannot correct. The problem could be due to a catastrophic hardware malfunction or a fault in the software.

Any permanent hardware failure gets discovered by the self-test function, and the unit will not be returned to service. If the fault was transient, the unit reinitialises, clears any calls that may have been left hanging, and resumes normal operation.

After they are properly installed, configured and operational, gateway units are extremely reliable. Software-detected errors seldom occur. It is usually impossible to diagnose the causative factors. Unless due to a persistent hardware problem, full recovery within a couple of minutes is automatic, although calls in progress at the time of the failure will have been cleared.

Diagnostic action

The error gets recorded in the unit’s event log automatically. When the unit restarts, record the content of the following logs:

• System

• Port

• Major

• Port Error

• Call Statistics

Event Reporting

Each Cisco VG30D Voice Gateway maintains an internal cyclic log of significant events and can report the contents of this log to a terminal that is attached to the management port. During normal operation, event reporting gets disabled, but when you are investigating problem conditions you can enable the event reporting function to assist in fault diagnosis. Reports may get filtered by class and severity to reduce the amount of information to be sifted.

If your supplier suggests that you do access the event log, they should tell you what classes of event to filter. For most purposes, you only need to display Alarm conditions, but more detailed information also gets maintained within the log in case of exceptional need. In practise, the most common faults are port errors. These conditions normally get diagnosed from the status LEDs or the port alarm log without a need to access the event log.

SNMP Traps

On a Cisco VG30D Voice Gateway that has been configured to use Ethernet, certain error conditions will cause a Simple Network Management Protocol (SNMP) trap to be sent to a configured IP address. Up to eight such addresses may be configured. These will contain basic information, but on receipt of the trap, the user is intended to connect to the Cisco VG30D Voice Gateway unit by using the Gateway management Interface for a more detailed summary. The following events will result in a trap being sent:

Browser Interface Problems

Symptom

Unable to connect a Web browser to the Gateway Management Interface.

Potential Cause and Action

A user is already logged in to the Cisco VG30D Voice Gateway, or the last user failed to log out. Retry connecting after waiting for the Non-Use Timeout period to expire.

Potential Cause and Action

Incorrect IP address entered. Enter the correct IP address. Confirm IP communications by “pinging” the unit. If pings succeed, activity can be seen on the Ethernet Port LEDs. If the Non-Use Timeout expired, access the unit by using the Craft Port to confirm correct IP Addresses and Sub Net Masks. Reboot the Cisco VG30D Voice Gateway and, if communication is restored, check the logs for errors.

Symptom

Management screens not updated as expected.

Potential Causes and Action

The Web browser has presented a cached page. The time and date information that is sent from the Cisco VG30D Voice Gateway gets recorded as earlier than the cached page date and time information, or the browser has been configured not to check for newer versions of stored pages.

Make sure that the browser is appropriately configured to check for newer versions of stored pages. Use the Web browser’s “delete all temporary files” or “clear cache” facility and retry.
