9.5.2  
Dial plan 
 


Settings | Least Cost Routing | Dial plan
 
For external connections, each call number including the code (up to a maximum of the 30th. character incl. field separators) is checked in the dial plan. The dial plan then determines a route table for the station; the station is assigned this table for the connection setup. Up to 16 routes are created via a single route table. The Dialing rules table defines how the digits selected by the station are converted and dialed by the communication system.
The station can cancel automatic selection by seizing a line directly (Carrier Select Override - CSO). If Internet telephony is set up via one or more ITSPs, a connection via the Internet is set up with the CO code, "0". In this case a connection via ISDN or the analog trunk connection is possible using the special CO code, "80".
The LCR class-of-service cannot be transferred between CorNet-networked communication systems.

9.5.2.1  
Table above (Call number evaluation for external connections) 

Name column  
The Name column can be used to assign a name to each profile, e.g., local call, long-distance call, international, etc. Depending on the version of the communication system, the Name column may or may not be displayed.
A meaningful name should be selected when assigning names. Multiple instances of the same name may be used. Appropriate names are automatically assigned via the Dial Rule wizard.

Dialed digits column  
The Dialed digits column specified the call number evaluation. Call numbers should be defined using the Digit Analysis wizard. To open the Dial Rule wizard, double-click the corresponding entry in the Dialed digits column or select an entry and then click the Dial rule wizard button. A description of the Dial rule wizard can be found in Section 9.5.2.3 "Digit Analysis Wizard".

Route table column  
The Route table column is used to specify which route table is to be used for the profile. The definition of the route tables then occurs via the table below (Route table).

Acc. code (Account code) column  
The Yes/No setting in this column determines whether or not an account code entry is mandatory after the seizure code (in USA: after end-of-dialing). If the No is selected, the account code is not required until the dial plan has been dialed completely if it has been configured for the route Call charges.../Account codes (see Account codes). An appropriate user prompt appears on telephones with a display.
ACCT entries must completed with Apply only if the entry is "unverified". The entry is saved automatically for "list verification" Call charges.../Account codes (see (Account codes) or "digit verification" Call charges.../Account codes (see Account codes).
For LCR configuration, note that all digits illustrate the Access Code (field E1) up to the first separator.  
Example: Station dials 2xx
   a)   Dial plan "2XX", dialing rule "A" => AccessCode="2xx", rest of dialing="" => "" is dialed!
   b)   Dial plan "2XX", Dial rule "E1" => AccessCode="2xx", rest of dialing="" => "2xx" is dialed
   c)   Dial plan "-2XX", Dial rule "A" => AccessCode="", rest of dialing="2xx" => "2xx" is dialed
   d)   Dial plan "2-XX", Dial rule "E1A" => AccessCode="2", rest of dialing="xx" => "2xx" is dialed
    The splitting up of the dialed digits in Access Code and rest of dialing is only changed by an alteration of the LCR - dial plan.

COS column (toll restriction)  
The COS (toll restriction) controls activation of the toll restriction. This applies to networking, as well as to standalone communication systems. With this, individual call numbers can be removed from the toll restriction. If the toll restriction should be applied, the known rules regarding the Allowed / Denied Lists apply (see Allowed/Denied numbers).

Emergency Column  
If a number that was configured as an emergency number (dialed digits, emergency column=yes) is dialed, and no free line is available, then a line that is being used for a non-emergency number (emergency column =no) is disconnected and then made available automatically for the emergency number.

9.5.2.2  
Lower table (Route table) 
Each path/route is described by a combination of routes, dial rules, LCR class-of-service, schedule and the designation of an expensive route. The LCR class-of-service is evaluated hierarchically for LCR. The route table is searched from top to bottom. If the route located is seized, or if the station does not have the necessary authorization, the next route is tried.
If the use of an entry fails because the route is not available, insufficient classes of service or not matching schedule, the next entry will be used, until all criteria match and the call can be established. When moving from one entry to the next, a warning about a more expensive connection may be announced if this has been configured for the overflow entry.

Route table drop-down list  
The Route table drop-down list is used to select the appropriate route table, which can then be edited in the table.
The type of digit transmission (see also Digit Transmission area (from HiPath 3000/5000 V8, HiPath OpenOffice EE V1 R2)) is displayed on the bottom right end of second table as static (e.g. route table 6: en-bloc sending).

Route column  
The route is selected here.

Dial rule column  
The dial rule is selected here. Dial rules should be defined by using the Dial rule wizard. To open the Dial Rule wizard, select an entry in the Dial rule column and then click the Dial rule wizard button. A description of the Dial Rule wizard can be found in Section 9.5.2.4 "Dial rule wizard".

min. COS column (Class of service)  
The min. COS describes the minimum LCR class-of-service needed by a station in order to use the associated route. It is thus possible to stipulate, for example, that one station is only permitted to place calls via a specific carrier or during certain times, while other stations have the option of using alternative routes.

Schedule column  
A time zone is entered here which is compared with the LCR schedule (see Schedule) If the comparison does not yield a match, the route is not enabled. Instead, the next route (next line) in the route table is tried. If a time zone has not been entered, the route is used without referring to the LCR time plan.

Warning column  
You define here whether a warning is to be output if an expensive connection (route) is being set up, and which warning should be selected. The warning Expensive connection is only displayed if a name has not been configured for the associated dial rule. If a name has been configured, it is displayed.

Digit Analysis Wizard 
The Digit Analysis wizard is used to define call number evaluation for external connections.
To call the wizard, click Settings | Least Cost Routing | Dial plan and then:
 •   double-click in the Dialed digits column
 •   or select the Dialed digits column and click the Dial rule wizard button
 •   or select it via the context menu (right mouse click) of the Dialed digits column

Profiles  
Some profiles are already predefined. You can use the options to select for which connections a call number evaluation is to occur, e.g., City for all local calls.
The User-defined option can be used to create profiles in addition to those already predefined.

Name  
The name for the profile is specified via Name. The predefined profiles are already assigned names.

Dialed digits  
Dialed digits specifies to which call number(s) the dial rule applies.
The following entries are permitted for the call number(s):
   -   0...9 (permitted digits)
   -   - (field separator)
   -   X (any digit between 0...9)
   -   N (any digit between 2...9)
   -   Z (one or more digits follow up to end-of-dialing)
   -   C (simulated dial tone (cannot be entered more than 3 times))
# within a dial string indicates end-of-dialing or switching of the signaling method; therefore * and # are not taken into account as entries here.  
In order to access all available functions, a field separator, "-", must be placed between the route code and the number you wish to dial.
When configuring LCR for a network, the dial plan for internal network call numbers should always be configured without access codes.

Except  
Except is specify exceptions, i.e., to which of the call numbers specified under Dialed digits the dial rule should not be applied.
Example using City:
    Dialed digits: 0CZ
Except: 0C0Z
    The dial rule applies only to local calls. If the value 0C0Z were not specified under Except, the dial rule would apply to all external calls, i.e., even long-distance calls, for example.

Set Route table, Acc. code, COS and Emergency to Standard  
If this option is activated (Standard), the values in the corresponding columns are reset to default values, i.e., no route table, Acc. code: no, COS; yes, emergency call: no
If the option is deactivated, a further dialog box is displayed in which the appropriate values can be selected.

Procedure  
Description  
Example  
Unknown  
 
 
Main network supplier  
When seizing a line via the main network provider, simple dialing is carried out either block-by-block or by dialing individual digits into the public network.
A
MCL single-stage  
With this type of LCR, the required network provider is selected with a prefix and the call number is then dialed via the D-channel in the case of ISDN or via the normal channel in the case of the MSI.
C123A
MCL two-stage  
With two-stage LCR, the required network provider is also selected with a prefix. Following a synchronization phase a configurable authorization code is first transmitted, followed by the destination call number (DTMF).
C131SP6M1A
Corporate Network (CN)
In the case of the Corporate Network, the alternative network is directly connected to the Hicom 150 E Office/HiPath 3000. This refers to the internal network of the company. The LCR function establishes the relevant route from the number dialed by the station and routes the call either via the trunk group of the public CO or via the trunk group with the corporate network. Both an open and a closed numbering system can be implemented using this method by means of digit manipulation.
E1A
Dial-in control server (DICS)  
With this type of LCR the required network provider is dialed with a prefix via a Dial In Control Server (DICS) and in the process the call number and a configurable authorization code is transmitted in the subaddress. The number is dialed via the D channel.
UM2A
Primary rate interface (PRI)  
In the case of Primary Rate Interface, the carrier or the calling service is selected in the SETUP via the information elements Network Specific Facility, Operator System Access and Transit Network Selection.
A
If Main network supplier is selected as the procedure in the dialing rules table, forwarding in the Route table will not work for the entries after the route programmed as the main network provider.
Normally in a Primary Rate Interface (PRI) environment, the central office does not require the 1 for long distance calls or 011 for international calls to be sent before the dialed number. In cases where the public network provider requires the 1 for long distance calls or the 011 for international calls, additional dial rules need to be created for long distance calls (D1A) and for international calls (D011A).

Access code, Pause (max. 12 sec.), Authorization code  
Depending on the procedure of the network provider, further parameters required for the dial rule must be specified.

Dial rule format  
The dial rules make it possible to actually access the various carriers by manipulating the digits. The dial rules address the fields of the dial plan directly in order to retry, suppress, exchange or insert digits. Other operations include the insertion of pauses, switching the signaling method or identification of the dial tone.
The dial rules are defined via the following special characters:


Parameter A  
A ensures that all subsequent digit fields are transmitted. The reference point is the last field indicator preceding A. A can occur more than once in the string and can be placed in any position. The AA combination is meaningless and has the same effect as A.
All
repeat remaining fields
(transmit)

Parameter D (n)  
D (n) can occur more than once in the string and can be placed in any position. D (n) can be surrounded by any other parameters.
Dial
Dial digit sequence
(1 to 25 digits)

Parameter E (n)  
E (n) can occur more than once in the string and can be placed in any position. E (n) can be arranged in any order, depending on n. A determining field can be addressed more than once, even consecutively. With the exception of the E1 A combination, E (n) can be surrounded by any other parameters.
Echo
retry field in dial plan
(Number 1 to 10)

Parameter P (n)  
P(n) can occur more than once in the string and can be placed in any position. P (n) can be surrounded by any other parameters.
Pause
Pause
(1 to 60 times the system-wide pause unit)

Parameter M (n)  
M (n) can occur only once in the string. M (n) should not be placed in the final position in the string.
Authorization Code
(1 to 16)

Parameter S  
S can occur only once in the string. S should not be placed in the final position in the string. After using S in the string, the C parameter may not be used.
Switch
Switch signaling method from DP to DTMF

Parameter U  
U can occur only once in the string. U should not be placed in the final position in the string. The subsequent characters are re-selected in INFO. After U the parameters S, P, C and M may not be used.
Use of the signaling method SUBaddress

Parameter C  
C can occur only once in the string. After C the following digits are sent without dial pause. C is used for carrier access with single stage, two stage, DICS and PRI.
Carrier
Access code
USA only:


Parameter N (n)  
N (n) can occur only once in the string. N should not be placed in the first position in the string. Depending on the service to be used, N designates the SFG.
Network-
specific
facility
SFG (1 to5) or Band Number (1)

Parameter L  
L can only occur at the end of a string of characters. L causes the call to be handled as an emergency call.
Location
identification
number
The call is treated as an emergency (E911)

min. COS Time slots, Warning  
This drop-down list corresponds to the respective columns in the route table (see Section 9.5.2 "Dial plan").

Type of Number [TON]  
For each dial rule, the following types of number from "Called Party Number" can be selected from the drop-down list:
 •   PABX number
 •   Local area code
 •   Country Code
"Unknown" is the default entry.
Sample options:
 •   Example:
    If the rule format "D492302667..." is entered, the TON "Country code" must be set. For the TON "Local Area Code" the rule format "D2302667..." should be configured, for example.
 •   Example - Called number supply:
    The called number (DAD) is configured via LCR, PABX number incoming:
    The number 0-089-722-4711 is dialed. The following should be sent: 49 89 722 4711. The dial plan contains 0C0-89722Z. The dial rule contains D49E3A and the type of number - country code (international).
The type of number is only set in E.164. In a conventional network, parameters are set to "Unknown".
