Add

Use the add command to add a telco-output rule. Once the telco-output rule is added, it can be applied to a voice interface using the set telco-output-rule configuration command under the Voice Net.

Syntax:

add: telco-output-rule

telco-output-rule

Specifies the sequence of dial digits to be sent out the telco interface when it is the destination of a call. The sequence is specified as a combination of the destination and source number dial digits passed during the call setup, constants, and pause characters.

Note:

The telco output rule is analogous to the IBM 9783's Destination Output Rule for a voice interface.

Example:

Voice config>add telco
 
Define Telco Output Rule #1
 
Digit  1 : (Source/Destination/Constant/Pause/End) [Destination]?
           (1-20) [1]?
Digit  2 : (Source/Destination/Constant/Pause/End) [Destination]?
           (1-20) [2]?
Digit  3 : (Source/Destination/Constant/Pause/End) [Destination]? e
Voice Config>a t 
 
Define Telco Output Rule #2
 
Digit  1 : (Source/Destination/Constant/Pause/End) [Destination]?
           (1-20) [1]?
Digit  2 : (Source/Destination/Constant/Pause/End) [Destination]? s
           (1-20) [2]?
Digit  3 : (Source/Destination/Constant/Pause/End) [Destination]? c
           (0-9, A-D, *, #) [0]? a
Digit  4 : (Source/Destination/Constant/Pause/End) [Destination]? p
Digit  5 : (Source/Destination/Constant/Pause/End) [Destination]? e

Digit #

Specifies how the specific dial digit is determined.

Source: Specifies to use the digit from the specified position in the source phone number.
Destination: Specifies to use the digit from the specified position in the destination phone number.
Constant: Specifies to always use the following constant digit (0-9, A--D, #, *) in the specified position.

Add

This command adds a network-output-rule, a dial-matching-rule, or a call-processing-rule to the VoFR configuration.

Syntax:

add: call-processing-rule
: dial-matching-rule
: network-output-rule

call-processing-rule

Specifies call-processing rules. For out-going calls, call processing rules are evaluated in ascending order by comparing the dialed digits to the dial digit matching rule associated with each call processing rule. If a match is found, the network output rule and call routing information in the call processing rule are used to process the call. Because a voice interface can accept calls from any destination specified in any of its associated call routing rules, this rule has no effect. Up to eight call processing rules can be defined for each voice interface.

Note: The call processing rule is analogous to the IBM 9783's Translation Rule, which combines a network output rule and a dial matching rule with call routing information (DLCI and subchannel specification in the case of a remote call route, number of destination digits to compare to local numbers in the case of a local call route).

Example:

VoFR Config>a c
Voice Net [0]? 8
 
Define Call Processing Rule #2
 
Destination Type (Local or Remote) [Remote]?
Call Processing DLCI (16 to 1007) [16]?
Payload         DLCI (16 to 1007) [16]?
Call Processing Subchannel (4 to 254) [4]?
Payload         Subchannel (4 to 254) [4]? 5
Dial Digit Matching Rule Number (0 to 3) [0]? 2
Network Output Rule Number (0 to 3) [0]? 1
 
 
VoFR Config>a c
Voice Net [0]? 8
 
Define Call Processing Rule #3
 
Destination Type (Local or Remote) [Remote]? l
Dial Digit Matching Rule Number (0 to 3) [0]? 1
Network Output Rule Number (0 to 2) ]0]? 1

Destination Type: Specifies whether the destination node is on another 2212/IBM 9783 (Remote) or another voice interface on the same 2212 (Local).
Call Processing DLCI: Specifies the DLCI that will be used to set up and then terminate the call.
Payload DLCI: Specifies the DLCI that will be used to send and receive the compressed voice data packets.
Call Processing Subchannel: Specifies the subchannel that will be used to set up and then terminate the call.
Payload Subchannel: Specifies the subchannel that will be used to send and receive the compressed voice data packets.
Dial Digit Matching Rule: Specifies the number of the dial digit matching rule to be used for this call processing rule.
Network Output Rule: Specifies the number of the network output rule to be used for this call processing rule.

dial-matching-rule

Specifies a dial digit pattern-matching sequence in which each element of the sequence specifies the range of acceptable digits at that position.

Note: The dial matching rule is analogous to the IBM 9783's Destination Match Rule.

Example:

VoFR Config>a d
 
Define Dial Digit Matching Rule #3
 
Dial Mask  1 : Digit String (0-9,A-D,*,#), [W]ildcard, [N]umeric Wildcard,
                                           [M]ultiDigit Wildcard.
               [MultiDigit Wildcard]?
 
Dial Mask  2 : Digit String (0-9,A-D,*,#), [W]ildcard, [N]umeric Wildcard,
                                           [M]ultiDigit Wildcard, or [E]nd.
               [End]?
 
Matching Rule contains MultiDigit Wildcard(s).
Minimum number of digits accepted for MultiDigit Wildcard (0,1) [1]?

Dial Mask #

Specifies one of a set of from 1 to 20 dial digit masks. Each mask specifies the acceptable range of the digit at that position in the 20 digit dial sequence.

Digit String: Specifies a set of digits from which the digit must be chosen.
Wildcard: Specifies that the digit must one of the following: 0-9, A-D, #, or *.
Numeric Wildcard: Specifies the digit must be 0-9.
Multidigit Wildcard: Specifies that more than one digit is acceptable at the specified position. If the multidigit wildcard mask is the last one in the dial matching rule, then any digit (0-9, A--D, #, *) may be entered at this point in the sequence. In this case the voice interface continues to collect digits until either 20 digits are entered or the Interdigit Timeout expires without additional digits being entered. If a mask follows the multidigit wildcard, the voice interface continues to collect digits that satisfy the multidigit mask until a digit is entered that satisfies the mask following the multidigit wildcard mask.

network-output-rule

Specifies the destination number digits to be passed in the Frame Relay call setup packet. The sequence is specified as a combination of the dialed digits received on the originating telco interface and constants.

Note:

The network output rule is analogous to the IBM 9783's Destination Output Rule for a Frame Relay interface.

Example:

VoFR Config>a n
 
Define Network Output Rule #2
 
Digit  1 : (Destination/Constant/End) [Destination]?
           (1-20) [1]?
Digit  2 : (Destination/Constant/End) [Destination]? e

Digit #

Specifies how the specific dial digit is determined.

Destination: Specifies to use the digit from the specified position in the destination phone number.
Constant: Specifies to always use the following constant digit (0-9, A--D, #, *) in the specified position.
End: Specifies the end of the digit sequence.

Delete

This command deletes a network-output-rule, a dial-matching-rule, or a call-processing-rule in the VoFR configuration.

Syntax:

delete: call-processing-rule
: dial-matching-rule

Voice Feature Dynamic Reconfiguration Support

This section describes dynamic reconfiguration (DR) as it affects Talk 6 and Talk 5 commands.

CONFIG (Talk 6) Delete Interface

Voice Feature supports the CONFIG (Talk 6) delete interface command with no restrictions.

GWCON (Talk 5) Activate Interface

Voice Feature does not support the GWCON (Talk 5) activate interface command.

GWCON (Talk 5) Reset Interface

Voice Feature supports the GWCON (Talk 5) reset interface command with the following consideration:

All Voice Feature parameters except FR-NET can be modified dynamically. Voice Feature parameters are defined once-per-router and apply to all voice interfaces on the router. After a Voice Feature parameter is changed, each voice interface must be manually reset in order for the change to be applied to it.

Voice Interfaces Dynamic Reconfiguration Support

This section describes dynamic reconfiguration (DR) as it affects Talk 6 and Talk 5 commands.

CONFIG (Talk 6) Delete Interface

Voice Interfaces support the CONFIG (Talk 6) delete interface command with the following consideration:

If one of the voice ports on a 2-port voice adapter is deleted, the other port on the adapter will be automatically deleted, because there is a restriction that requires both ports on a 2-port voice adapter to be configured as present.

GWCON (Talk 5) Activate Interface

Voice Interfaces do not support the GWCON (Talk 5) activate interface command.

GWCON (Talk 5) Reset Interface

Voice Interfaces support the GWCON (Talk 5) reset interface command. All Voice Interface parameters can be modified dynamically.

Footnotes:
