1.1 area
To set busy tone type detection for ports, use the area command. To return to the
default, use the no form of this command.
area { north-america | custom | europe }
no area
Syntax Description
north-america The busy tone type of the switch connected to this interface is of North
America standard.
custom The busy tone type of the switch connected to this interface is defined by the
users.
europe The busy tone type of the switch connected to this interface is of Europestandard.
Default
By default, europe busy tone type standard is set.
Command Mode
Voice-port configuration mode
Usage Guideline
This command is used only for 2-wire loop trunk interface FXO, and it can only performconfiguration to the first port on the voice interface card. If successful, the configurationwill be effective for all the ports of the voice interface card.
When this interface is connected to a common user line of a program-controlled switch,
if the user on the switch side hooks on first, only by detecting the busy tone can the
router know the user on-hooking operation. Since different switches execute differentprompt tone schemes, there exist different frequency spectrum characteristics. Thiscommand is used to set the frequency spectrum characteristic used by the router todetect the existence of the busy tone.
Example
! The following example uses north-america standard to detect the existence of thebusy tone on port 0.
Quidway(config-voice-port0)# area north-america
1.2 cancel-truncate
To cancel the truncating of a called number, use the cancel-truncate command. To
return to the default, so as to truncate a called number, use the no form of thiscommand.

1-3
Default
By default, truncate a called number.
Command Mode
Dial-peer configuration mode
Usage Guideline
In common cases, if the structure of POTS dial-peer type is defined on the FXO, E&M
or E1VI interfaces, and the destination-pattern is configured with a wild-card .,then
when the router receives an incoming call, it will truncate and delete the fixed numberbefore the wild-card by default, and only transmit the number to which the wild-cardcorresponds from this interface.
Whereas if the function of cancel-truncate is configured, a called number will not be
truncated, and all the numbers received will be transmitted from the trunk interface. Forinstance, a POTS dial-peer structure is configured on the FXO interface, thedestination-pattern is configured as 9 . (the four dots as the wild-card), then when
the router receives an incoming call whose number is 91234, the router will delete the 9on the FXO interface by default, and transmit only the 1234 through the FXO interface;ifcancel-truncate is configured, the router will transmit the whole number (91234),
without deleting the 9. This function enables routers to flexibly process numbersaccording to different switches at the remote end.
Example
! The following example configures POTS dial-peer, the number before the wild-card is
9, and transmits all the received numbers from the FXO interface.
Quidway(config-peer-pots1)# destination-pattern 9....
Quidway(config-peer-pots1)# cancel-truncate
Related Command
destination-pattern
1.3 codec
To set the voice codec mode according to priority level, use the codec demand. Toreturn to the default, use the no form of this command.
codec { 1st-priority-level | 2nd-priority-level | 3rd-priority-level | 4th-priority-level }
{ g711alaw | g711ulaw | g723r53 | g723r63 | g729r8 }
no codec { 1st-priority-level | 2nd-priority-level | 3rd-priority-level | 4th-priority-
level }
Syntax Description
1st-priority-level Indicate the first selected voice codec method.
2nd-priority-level Indicate the second selected voice codec method.
3rd-priority-level Indicate the third selected voice codec method.
4th-priority-level Indicate the fourth selected voice codec method.

g711alaw Indicate the A-law coding mode of G.711 (defining the pulse code
modulation technology), the bandwidth is 64kbit/s, usually adopted by Europe.
g711ulaw Indicate the -law coding mode of G.711, the bandwidth is 64kbit/s, usually
adopted by countries of the North America and Japan, etc.g723r53 Indicate G.723.1 Annex A (dual-speed voice coding of multi-media
communication, based on multi-pulse, multi-level quantization and code excited linearprediction technology) coding mode, the bandwidth is 5.3kbit/s.
g723r63 Indicate G.723.1 Annex A coding mode, the bandwidth is 6.3kbit/s.
g729r8 Indicate G.729 (the voice coding technology using conjugate algebraic code
excited linear prediction) coding mode, the bandwidth is 8kbit/s.
Default
By default, g729r8 coding mode is set.
Command Mode
Dial-peer configuration mode
Usage Guideline
Use codec command to specify voice codec modes of different priority levels.
g711alaw and g711ulaw coding provide high-quality voice transmission, but occupy
greater bandwidth.
g723r53 and g723r63 coding provide silence suppression technology and comfort
noise, the relatively higher speed output is based on multi-pulse multi-quantitative leveltechnology and provides relatively higher voice quality to certain extent, and therelatively lower speed output is based on the code excited linear prediction technologyand provides greater flexibility for application.
The voice quality provided by the g729r8 coding is similar to the ADPCM of 32kbit/s,
having the quality of a toll, and also featuring low bandwidth, lesser event delay andmedium processing complexity, hence it has a wide field of application.
Only when there is an intersection (a codec mode recognized by both parties) in the
voice codec modes owned by the two communication parties can the two partiesestablish normal communication with each other. If there is no consistency in the codecmodes set for the equipment at the two ends connected to each other, or there is nocommon codec method, the calling will fail.
Example
! Then following example configures to select g723r53 codec method first, then to
select the g729r8 codec method.
Quidway(config-peer-voip2)# codec 1st-priority-level g723r53Quidway(config-peer-voip2)# codec 2nd-priority-level g729r8

Example
! The following example identifies voice port 1 as connected to laboratory lab_1.
Quidway(config-voice-port1)# description lab_1
1.7 destination-pattern
To configure the destination mode of a dial-peer, namely, to use a prefix or a wholeE.164 number, use the destination-pattern command. To cancel this setting, use theno form of this command.
destination-pattern [ + ] string[ T ]
no destination-pattern
Syntax Description
+ Used as the first character to indicate that this is a standard E.164 number.

l 0 - 9, # , * .l , , indicating a pause between digits.l . , used as a wild-card, indicating that it can match any input digit.
Command Mode
Dial-peer configuration mode
Usage Guideline
Use destination-pattern command to define an E.164 number for a dial peer, so as to
match the dial to this dial-peer. If successful, the call will be completed by the dial-peer.When the command is used to set the E.164 telephone number, and when the router
receives a call request, it will strip off the mode string according to the telephonenumber carried in the message. If a prefix is configured, the prefix will be added to thetelephone number carried. If all the modes are successfully matched, the user will hear
a ring back tone.
& Note:
VRP software does not verify the validity of an E.164 number.
Example
! The following example sets 5557922 as the telephone number of dial-peer 10.
Quidway(config-peer-pots10)# destination-pattern +5557922

Usage Guideline
In the application note that the program running on the same voice interface card can
only simultaneously support G.711 and G.723.1, or G.711 and G.729, but cannotsimultaneously support G.729 and G.723.1 protocols.
As a called party, the codec protocol supported on the voice card should be in
consistency with the codec type set in the dial-peer of the POTS type that had been
established relation with the card port; and as a caller, the codec protocol on the cardshould be in consistency with codec type set in the dial-peer of the VolP type usedduring the outgoing calling from the POTS port on the card. Otherwise it will lead to
unidirectional conversation or even no conversation. When changing the codecprotocol program on the voice card, be sure to check the codec protocol setting of thedial-peer related to the port on the voice card.

1.11 echo-cancel
To configure echo-cancel function parameters, use the echo-cancel command. Tocancel the echo-cancel function parameters setting, use the no form of this command.
echo-cancel { enable | coverage coverage-time }
no echo-cancel { enable | coverage }
Syntax Description
enable Indicate to enable an echo-cancel function.
coverage coverage-time Adjust the length of an echo-cancel sampling time. The
values for the coverage-time are 16, 24 and 32 in millisecond (ms).
Default
By default, the echo-cancel function is enabled and the coverage-time is 16 ms.
Command Mode
Voice-port configuration mode
Usage Guideline
Use the echo-cancel coverage command, if the voice originated from a certain
interface is fed back within a specified time, this part of voice (echo) will be cancelled.
If a too large time value is set, the converge time of the echo canceling on the network
will become longer, so when the connection has just been established, the user mayhear the echo; and if the time value is set as too small, the user may also hear part ofthe echo, because the relatively longer echo has not been completely cancelled.
There are no echo and echo-cancel on the IP side.
& Note:
Only when being used in combination with the echo-cancel coverage command will
effect the echo-cancel enable command.
Example
! The following example sets the echo-cancel sampling time as 24 ms on voice port 1.
Quidway(config-voice-port1)# echo-cancel enable
Quidway(config-voice-port1)# echo-cancel coverage 24

Usage Guideline
Specify the voice flow IP data package priority level related to this dial-peer. In the
command, when the value ofpriority-number is between 1 and 5, it indicates that the
configuration is set for the IP data flow, and values 6 and 7 are used for the update ofthe network and backbone routers. For instance, in order to ensure the voice flowrelated to the dial-peer 103 which is of the VolP type, the IP data package priority level
is defined as 5, then when an IP call is related to this dial-peer 103, the TOS field of theIP header of all the data packages transmitted to the IP network through this dial-peer
are set as 5. When the network receives these packages that have been set with arecognized priority levels, these packages will be processed before those packageswith relatively lower priority levels..

To select a wire scheme for the E&M interface, use the operation command. To deletean existing wire selection scheme, use the no form of this command.
operation { 2-wire | 4-wire }
no operation { 2-wire | 4-wire }
Syntax Description
2-wire Indicate to select a 2-wire E&M wire scheme.
4-wire Indicate to select a 4-wire E&M wire scheme.
Default
By default, select a 4-wire E&M wire scheme.
Command Mode
Voice-port configuration mode
Usage Guideline
When E&M is used in PBX communication, its voice uses two or four wires, plus two orfour signaling wires. So, a 4-wire E&M actually has at least six wires.
This command is used for the wire match between the voice router and remote end
equipment connected with it. It has influence on voice transmission only and has
nothing to do with signaling. If a wrong wire scheme is configured, the user will get aunidirectional voice service only.
This command is not used to the FXS and FXO interfaces, because these both are 2-
wire interfaces.
Example
! The following example sets that the E&M interface selects a 4-wire wire scheme.

Usage Guideline
Of the E&M signaling types, a PBX transmits signals on the M line (M means Mouth,
indicating it is transmitted from a PBX), and receives signals from E line (E means Ear,indicating it is received by the PBX). So, as to a router that has voice function, the routerreceives the M signal of the PBX, and transmits E signal to the PBX.
E&M interface has four data transmission (signal) lines, and two or all the four lines areused according to different types:
E (Ear or Earth ): the signal line from the router side to the PBX side.
M ( Mouth or Magnet ): the signal line from the PBX side to the router side.
SG (Signal Ground): used for some types of E&M only.
SB (Signal Battery): used for some types of E&M only.

VAD is an abbreviation of Voice Activity Detection, generally termed as silence
detection. Its basic idea is to detect and delete any silence on the basis of the difference
of energy between the voice signals of people s conversation and their silence signals,so that no signals are produced; and only when an abrupt activity tone is detected will avoice signal be generated and transmitted. It is shown by research that no less than50% transmission bandwidth can be attained by the use of VAD technology.

two dial-peers. when the user dials 01066880011, if the router is configured with theshortest number match-policy, then the router originates a connection to 0106688 atthe remote end, and the four numbers 0011 will not be processed; if the router is
configured with the longest number match-policy, and the user only dials 0106688, therouter will wait for the user to dial. After timeout, the number match-policy configuredwith the system is neglected, and the shortest number match-policy will be
automatically followed to make a call; if the user dials 0106688# (here the "#represents the dial terminator configured by the system), the router will likewise neglectthe number match-policy configured by the system and use the shortest number
match-policy, thus providing a greater flexibility for the configuration of user dialscheme.

2.1 fax level
To configure the gateway carrier transmitting energy level, use the fax level command.
To return to the default, use the no form of this command.
fax level level
no fax level
Syntax Description
level Gateway carrier transmitting energy level, ranging 3 to 60.
Default
15
Command Mode
Dial-peer configuration mode
Usage Guideline
Usually the default of the gateway carrier transmitting energy level is acceptable. If fax
still can t be sent when other configurations are correct, you can try to adjust thegateway carrier transmitting energy level.
Example
! The following example configures the gateway carrier transmitting energy level as 20.

2.2 fax local-train
To configure the fax local training threshold value, use the fax local-train command. To
return to the default, use the no form of this command.
fax local - t rain thresh oldthreshold
no fax local-train threshold
Syntax Description
threshold Local training threshold value, ranging 0 to 100.
Default
15
Command Mode
Dial-peer configuration mode
Usage Guideline
When rate training is being carried on between FAXes, the transmitting FAX transmits
the 0 TCF data at 1.5s10% to the receiving FAX, and the receiving FAX decideswhether or not the rate is acceptable according to the TCF data received.
The command is used to configure the local training threshold value if the local training
mode is configured. Error happens during the TCF transmission if 1 appears in theTCF data received. If the number of 1 received is less than the threshold valueconfigured, the transmission is successful, otherwise, it is unsuccessful.
Example
! The following example configures the fax local training threshold to 20.
Quidway(config-peer-pots1)# fax local-train threshold 20
2.3 fax protocol
To configure the number of transmitting redundant packets of T38 fax protocol, use thefax protocol command. To return to the default, use the no form of this command.
fax protocol { t38 [ ls-redundancyt38number| hs-redundancynumber] | cisco }
no fax protocol { t38 [ ls-redundancy | hs-redundancy ] | cisco }
Syntax Description
t38 Using the T38 fax protocol.
Isredundancy Configuring the number of redundant packets of low rate data,
ranging 0 to 5.

hs-redundancy Configuring the number of redundant packets of high rate data,
ranging 0 to 2.
cisco Using the fax protocol which is compatible with CISCO.
Default
The two kind of redundant packets are 0.
Command Mode
Dial-peer configuration mode
Usage Guideline
The low rate indicates the V21 command data, and the high rate indicates the TCF data
and figure data.
When connected with CISCO fax terminal, you need to choose CISCO fax protocol.
When connected with other fax terminals that support T.38 protocol, you need to
choose T.38 protocol. Because CISCO devices do not support the mode of local faxtraining, you have to adopt the mode of point-to-point training for the connection withCISCO devices.
Example
! The following example configures the number of the transmitting redundant packets of
T38 fax protocol to 20.
Quidway(config-peer-pots1)# fax protocol t38 hs-redundancy 2
2.4 fax rate
To set the highest speed enabled by the gateway, use the fax rate command.
fax rate{ 12000 | 14400 | 2400 | 4800 | 7200 | 9600 | disable | voice }
Syntax Description
If the setting is the values except disable and voice , then set the fax rates to the
corresponding values. The set rate is the highest rate enabled, instead of the only rate
specified.
If the setting is the voice mode, the highest rate enabled by the fax will be finallydecided according to the voice codec protocols.
l If the voice codec protocol uses G.711, the fax rate is 14,400bit/s.
l If the voice codec protocol uses G.723.1 Annex A, the fax rate is 4,800bit/s.
l If the voice codec protocol uses G.729, the fax rate is 7,200bit/s.
If the setting is disable , the fax function will be disabled.
Default
voice

2.5 fax support-mode
To configure the fax interworking mode with other equipment, use the fax support-
mode, command.
fax suppor t -mode{ standard | rtp | vt }
Syntax Description
standard Standard mode.
rtp RTP mode.
vt The mode when interworking with the VocalTec gateway.
Default
rtp
Command Mode
Dial-peer configuration mode
Usage Guideline
Under common conditions, use the RTP mode. When interworking with the VocalTec
gateway, the vt mode is adopted. At present, standard mode does not supportinterworking with the VocalTec gateway.

2.6 fax train-mode
To set the training mode used by the gateway, use the fax train-mode command.
fax t ra in -mod e{ local | ppp }
Syntax Description
local Using the local training mode.
ppp Using the point-to-point training mode.
Default
local
Command Mode
Dial-peer configuration mode
Usage Guideline
The local training mode means that the gateway participates in the rate training
between the FAXes at both ends. In this mode, first carry on the training between theFAXes and between the gateways respectively, then the receiving gateway will transmit
the training result of the receiving end to the gateway at the transmitting end. Thetransmitting gateway will decide the final packet transmission rate according to thetraining results of both ends.
The point-to-point training mode means that the gateway does not participates in the
rate training between the FAXes at both ends. In this mode, the rate training is carriedon between the FAXes at both ends, and it is transparent to the gateway.
Example
! The following exampl
