9.4.9 Routing parameters

9.4.9	Routing parameters

Settings | Lines/networking | Routing parameters

Routing parameters can be used to set the parameters for each of the routes listed under Routes. Depending on your requirements, you can turn on individual flags, choose options, and change default values here.

9.4.9.1

Routes list

Routing parameters, like the Routes, contain a list of the routes in the communication system. The names that you assign to the routes, are displayed via Routes. To select a route, click on the route name (or the number) in the appropriate list box.

9.4.9.2

Area: Routing flags

Digit Repetition On flag

If an outgoing route is seized and digit repetition has been activated, the routing code is automatically included as the initial portion of the call number. This only applies if LCR is deactivated (see Settings | Least Cost Routing). If LCR is activated, closed numbering is only implemented via the LCR tables.

This feature is used with networked communication systems with a closed numbering system to reach a station always with the same call number. The communication system used to set up the call is irrelevant.

In order to use digit repetition for closed numbering, the call numbering plans of the other networked communication systems must be coordinated to ensure that their call numbers begin with codes that are stored in the Routing codes field for the corresponding route in the present communication system (see Routes). To achieve a higher level of flexibility, up to ten routing codes can be defined for each route.

In case of a digital network, the LCR dial plan should be used to define the different access codes and digit repetition.

Analysis of Second Dial Tone flag

Analysis of Second Dial Tone alerts the communication system to detect an additional dial tone. This feature is used with tandem communication system applications. This evaluation is country-dependent, e.g., in Belgium after 00 and in France after 16 or 19. This is not relevant in Germany. This only applies to network providers who send a second dial tone for international calls.

Intercept Per Direction flag

This flag is necessary for QSIG networking. When this flag is set, the communication system checks whether a diversion request has been received by the remote station, or whether the communication system has implemented forward switching to the central intercept position. The remote station receives a message which advises whether or not a diversion should be implemented for this call.

If intercept is activated for a route, all calls forwarded to this route are intercepted at this intercept position.

To implement this feature, day and night numbers must be configured for each route (see Ringing assignment per line). Furthermore, an intercept position should not be entered for the day/night service (see Intercept / Attendant).

Over. service 3.1 kHz audio flag

For all outgoing calls on ISDN, Over. service 3.1 kHz audio is the default setting. This is the standard transmission type for outgoing calls on an Integrated Services Digital Network (ISDN) line. A connection from the communication system to a digital CO with an analog modem must be identified as a data service.

This flag should be set to avoid problems during FAX operation.

The default setting should not be changed without consulting the respective network operator.

Trk Grp. - Add Routing Prefix Incoming flag

When this option is activated on system telephones with incoming seizure, the call number display is supplemented by the route code. When the option is deactivated, address information elements are forwarded transparently from the CO to the S0 station.

Trk Grp. - Add Routing Prefix Outgoing flag

When this option is activated on system telephones with outgoing seizure, the call number display is supplemented with the access code.

This flag should only be deleted for an LCR dial plan configuration in which all dial plan entries begin with `-' and for a CO connection in which the connect message does not include any call number information (for example, VPN Arcor / Deutsche Bahn).

Ring-back-tone to CO flag

If this flag is set, a 'Ring-back tone' will be sent to the ISDN central office on an incoming call.

This is a special protocol handling required for the provider Global One and Sovintel.

Keypad Dial flag

Indicates whether this route supports carrying out of stimulus procedures to the ISDN CO.

A subscriber who would like to carry out these procedures needs the correct authorization to do so (see Station view: Flags).

LIN activated flag (only for the USA)

Here, the user enters whether the route of sending from LIN (Local Identification Number) is supported. If the communication system determines during the first attempt that this route does not support the LIN, this flag is automatically reset.

This flag is only relevant for primary multiplex connections (TMST1).

Adaptation to DMS100 CO flag

Activating this option adapts the communication system to the behavior of the DMS100 CO in Israel. All incoming calls (CdPNr) with the code "type of number (TON) = unknown" are evaluated in the communication system as call numbers with the code "TON = subscriber". This flag is not configured in the default setting.

Deactivate UUS per Direction flag

User-to-User Signaling (UUS) can be deactivated with this flag. This suppresses the transmission of the name and phone number of the A station in the UUI element (user-to-user information, UUI) for external call forwarding (FWD ext.). This flag must be manually deactivated for Telefonica.

Name in CO

The name of the calling party is sent to the Central Office in the "user to user information (UUI)" element. This flag must be manually deactivated for Telefonica.

9.4.9.3

Area: Segmentation

This area defines the system behavior when sending ISDN messages in which the maximum Layer 2 user data length (260 bytes) is exceeded.

yes

The message to be sent is split into 260-byte segments and sent individually. The receiving communication system must support the segmentation and collect and arrange the individual segments into a message.

Segmentation is not needed, since the underlying Layer 2 can transport messages of any length.

Truncate Message

The message to be sent is truncated to less than 260 bytes by eliminating the less important portions (such as names, for example) and then sent.

Segmentation is only significant for trunks with the CorNet-NQ, ISO-QSIG (QSIG V2) and ECMA-QSIG (QSIG V1) protocols.

9.4.9.4

Area: Analog trunk seizure, no pause

Here various times can be selected which determine when dialing begins when using analog dial-up lines (MSI). If no pause is set, the communication system waits until it recognizes a dial tone.

Note for Brazil

When using DTMF signaling from analog terminals in conjunction with analog trunks (TLAx and TML8W) and digit outpulsing after dial tone detection, there might be problems with the toll restriction when the country code is set to Brazil. In this case, the DTMF signals from the analog terminals go directly to the analog trunks ("1A procedure" is not used). Because of this, the DTMF signals which are dialed before the dial tone is received are lost.

Here, Least cost routing (LCR) must be activated for proper functionality of the terminal dialing process and toll restriction.

9.4.9.5

Area: Trunk call pause

The Trunk call pause field refers to the trunk call ring cycle. The CO call pause determines the period of time that elapses before a call is recognized as being completed once the user has hung up.

This option applies only to MSI lines.

For a trunk call with, for example, 1 second on and 4 seconds off, a trunk call pause of 6 seconds should be configured. In some COs, however, a 10-second ring pause applies. In such cases, a trunk call pause of 13 seconds must be programmed. Otherwise, no call diversion can be implemented.

In the United States, this cycle is two seconds on, two seconds off, for a total of six seconds. The six-second option is the default, so you will not need to make any changes here.

Setting range: 2 to 13 seconds.

9.4.9.6

Area: Type of Seizure, Cyclic, Linear

This field specifies the criteria that apply if the communication system needs to seize an outgoing line.

Cyclic

The communication system starts its cyclical search for a free line with the next line number based on the last outgoing line seized in this route.

Linear

The communication system always begins its search with the lowest line number assigned to this route.

TMANI/TLANI boards are reinitialized if this flag changes.

9.4.9.7

Area: Route type, CO, PABX

There are two options for Route type. The type of route can be set either as CO (Central Office) or as PABX (Private Automatic Branch Exchange).

Lines assigned to this route are subject to toll restriction.

When LCR is active, the toll restriction is regulated by Dial plan (COS column).

PABX

Toll restriction is only performed if there is a second CO code assigned to this route. When LCR is active, the toll restriction is regulated by Dial plan (COS column).

The route type also has a bearing on the default text of the route name (see Routes) as well as on the procedure used for recognizing the dial tone on MSI lines.

9.4.9.8

Area: No. and type, outgoing ...

In a PRI environment, in the No. and type, outgoing area, you can specify the number and type of the digits that will be sent to the CO and the receiver according to the different prefixes and requirements. In the USA, the entry commonly used for PRI is Local area code.

The settings in the No. and type, outgoing area also affect calls which are sent from a remote station that is connected to a networked node. The number of the caller which is received from the networked node and forwarded to the CO, is upgraded based on this setting for the outgoing route.

Unknown

This setting is the default selection. If this option is selected, the DID number assigned to the station will be sent. It may include 7, 10, or 11 digits.

PABX number

If you select PABX number, the communication system will send seven digits to the CO. These digits include a three-digit PABX code and a four-digit DID extension number.

Local Area Code

If you select Local Area Code, the communication system will send ten digits to the CO. These digits include a three-digit area code and a seven-digit number, which includes a PABX code plus a station number.

Country Code

If you select Country Code, the communication system will send eleven digits to the CO. These digits include a one-digit country code and a ten-digit number, which includes a local area code, a PABX number, and an DID extension number.

Internal

This setting is essential for a networked system. Number prefixes may not be added for closed numbering plans. If this setting is selected, call number prefixes are suppressed.

9.4.9.9

Area: Call number type, ...

This field allows you to specify the call number information which is transmitted from the calling station to the destination station.

Internal

In this case, only the internal call number is transmitted. If the destination is an external station, either no number is transmitted of only that of the attendant. The internal call number can be displayed when the destination is an internal station.

Direct inward dialing (DID)

In this case, only the DID number is transmitted. The internal call number is not provided for display at internal destinations in other nodes. The call number is sufficient for external destinations.

Internal / DID

This setting is useful for networking purposes. Both the internal call number and the DID call number are transmitted to the destination station. If an internal station is called within the network, the internal call number of the caller can be displayed for this station. If the internal destination station has activated call forwarding to an external destination, for example, a DID number can also be transmitted in this case.

9.4.9.10

Area: Rerouting

To optimize use of the B-channel, call forwarding can be performed on the basis of the protocol in accordance with the specification "Call Forwarding/Partial Rerouting". If partial rerouting is rejected, forward switching is used.

This option is only available for CorNet networking, and must be activated in the same way in both networked communication systems.

Change route

When this flag is turned on, it is also possible to route D-channel information via other routes.

This option enables alternative routing via other routes. The option may be activated only when the call number plan is unambiguous (closed numbering or unique seizure codes in a network. The system making the request must also support this.).

If rerouting is implemented, rerouting with change route active must also be set for the corresponding route.

9.4.9.11

Area: Rerouting active

When you select this option, Rerouting is deactivated. For call forwarding, the connection is always set up via two B-channels.

If route is known

When you select this option, rerouting is only active if the route is known and a successful "handshake" procedure takes place between the two networked communication systems.

Always

If the setup for the incoming call is coming in on the same route as the call forwarding destination route, the call will be rejected by the communication system if this option is activated.

This option Always is only available for CorNet networking, and must be activated in the same way in both networked communication systems.
