The voice commands apply to setting up and configuring, and statistical reporting for voice connections (including FAX). In addition to the command descriptions, this chapter describes how to add a voice connection, configure card redundancy, and optimize the use of voice activity detection (VAD). A list of the commands that let you modify most characteristics of voice and data connections also appears at the front of the chapter. Use this list as a guideline for building voice service.

Voice connections exist as ports on circuit lines that are supported by a Channelized Voice Module (CVM) or Universal Voice Module (UVM) in an IGX node. The back card for the CDP or CVM is either a BC-T1, BC-E1, or BC-J1. For the UVM, the back card is either a BC-UVI-2T1EC, a BC-UVI-2J1EC, or BC-UVI-2E1EC.

Setting Up a Voice Connection

The following steps describe how to set up a voice connection.

Step 1 Configure the voice channel at each end of the connection. The associated commands are:

upln	Use upln to activate the line.
cnfcassw	If the UVM must convert CAS/DTMF to CCS signaling for a Voice Network Switch (VNS), use cnfcassw to configure the UVM for CAS switching. For CAS switching, the minimum UVM firmware level is B. Note that CAS switching is incompatible with passthrough. Before you use addcon to add signaling channels (to slot.port.24 or slot.port.16 for T1 or E1, respectively), specify "PBX-end" mode with cnfcassw.
cnflnpass	For a UVM intended to carry voice traffic with low delay code-excited linear predictive coding (LDCELP) or conjugative algebraic code-excited linear predictive coding (CACELP) per G.729, use cnflnpass to configure the UVM lines for the passthrough feature. Refer to the Cisco IGX Reference for a description of passthrough. Before you can execute cnflnpass, you must activate (upln) and configure (cnfln) the lines. Note that passthrough is incompatible with CAS-switching.
cnfchadv	Configures the channel for adaptive voice (ADV). This command enables or disables adaptive voice compression for one or more voice channels. The feature must be configured at both ends of the channel.
cnfchdl	Configures a channel's dial-type. The options are inband, pulse, and user-configured.
cnfchec	Configure the echo canceller for the channel. The command enables or disables the echo canceller for a range of voice channel, sets the echo return loss to high or low and enables/disables the tone disabler, convergence, and non-linear processing.
cnfchgn	Configures the amount of gain inserted in a voice channel.
cnfcond	Configures a conditioning template for the channel.
cnfrcvsig	Configures receive signaling for the channel.
cnfxmtsig	Configures transmit signaling for the channel.
cnfvchtp	Configures a voice interface type for the channel.
cnfchutl	Configures channel utilization (see "Optimizing Traffic Routing and Bandwidth" chapter).
addyred	Enables voice channel redundancy.
dsplncnf	Use dsplncnf to make sure you have correctly configured the line.

Step 2 Add the connections with the addcon command. You must complete the appropriate steps at each end by using the commands in the preceding list before you add connections.

Configuring Voice Channel Redundancy

You can configure voice cards for redundancy by installing two identical card sets in adjacent slots and connecting them to the CPE through a Y-cable. Configure redundancy by using addyred. Note that a switch to a standby UVM that has active CAS-switching causes the loss of all call states.

Using VAD and Configuring Voice Channel Utilization

The bandwidth savings you gain by using VAD are less than optimal if you do not set the utilization of the voice channels to a reasonable value. To configure the utilization, use the cnfchutl command.

addcon

Establishes the channel connections between nodes in the network. You can add voice connections to any slot that has a CDP, UVM, or CVM. Before you add a connection, determine its compression type.

If you plan for a port on a UVM to carry more than 16 channels with LDCELP or the G.729 version of CACELP, you must have a second, connected UVM and configure the resultant pair of UVMs for passthrough operation. If you attempt to add more than 16 LDCELP or G.729 channels, the system reports any excess connections as being failed connections after addcon execution finishes. Furthermore, if you execute dspcon, the status display for the excess connections shows "ConnRJ" (connection rejected). Refer to the cnflnpass description in this chapter and the UVM description in the Cisco IGX Reference for a description of passthrough.

After you have established passthrough for a pair of UVM card sets, the system does not allow duplication of channel numbers when you add connections. For example, if you add 7.1.1-16, the node does not allow you to add 8.1.1-8 if you have linked the UVMs by using cnflnpass. Instead, you would add 8.1.17-24.

A UVM with Model B or higher firmware supports CAS switching. Before you can add connections in a network with CAS switching, you must configure the UVM for this feature with the cnfcassw command. Note that, for CAS switching, you use addcon to add the signaling channels at the near and far end in the format slot.port.24 on a T1 line and slot.port.16 on an E1 line. Also, the connection type for these signaling channels is "t." If you specify D-channel compression, the connection type is "td." See the description of cnfcassw in the "Setting Up Lines" chapter or, for a more detailed description, the manual titled Cisco VNS (Voice Network Switching) Installation and Operation.

When adding a range of channels, you do not have to specify the full channel set at the near-end. You may specify only the first channel in the set. For example, to connect channels 13.1-10 at alpha to channels 12.5-14 at beta, you could enter "addcon 13.1-10 beta 12.5." In this example, channel 13.1 is connected to channel 12.5, and channel 13.2 is connected to channel 12.6, and so on.

Connections are added with a default class of service (COS). The value of COS is the number of seconds that the node waits before it reroutes the connection after a failure. The COS applies to various types of connections other than voice and therefore is described elsewhere (see the cnfcos description in the "Optimizing Traffic Routing and Bandwidth" chapter).

Table 6-2 and Table 6-3 describe what you enter for the type parameter for each rate and compression variable.

Table 6-2: Types of CDP and CVM Operation

Rate	VAD	No VAD	Comment
64 Kbps	v	p	None.
32 Kbps	c32	a32	None.
32 Kbps for FAX	c32d	a32d	Specifies 32 Kbps specially optimized for FAX; c32d incorporates Voice Activity Detection (VAD).
24 Kbps ADPCM	c24	a24	None.
16 Kbps no ZCS	c16z	a16z	For non-ZCS only.
16 Kbps	c16	a16	ZCS is permissible; c16 and a16 use non-standard compression algorithms.

Table 6-3: Types of UVM Operation

Rate	VAD	No VAD	Comment
64 Kbps	v	p, t	Pass-through does not accept t-type connections.
32 Kbps	c32	a32	None.
24 Kbps ADPCM	c24	a24	None.
16 Kbps no ZCS	l16V	l16	For non-ZCS only.
8 Kbps	g729r8v g729ar8v	g7298 g729ar8	The UVM supports two forms of CACELP. Both versions can support VAD (or no VAD). The "a" indicates G.729A. The other version is G.729.

Table 6-4: Types of UVM Connections

Connection	Description
p	A p-connection carries 64 Kbps PCM voice and supports A-law or micro-law encoding and conversion, gain adjustment, and signaling.
t	A t-connection carries 64 Kbps clear channel data traffic.
td	A td-connection carries compressed, 16 Kbps signaling between an IGX node and VNS unit.
v	A v-connection is the same as "p" (above) but with VAD.
a32 a24	Specifies ADPCM only. You can specify 32 Kbps or 24 Kbps.
c32 c24	Specifies both ADPCM and VAD. You can specify 32 Kbps or 24 Kbps.
l16	LDCELP compression of voice to 16 Kbps.
l16v	LDCELP compression of voice to 16 Kbps with VAD.
g729r8	CACELP voice compression at 8 Kbps according to G.729. This type also supports automatic FAX and modem upgrade.
g729r8v	CACELP voice compression at 8 Kbps with VAD according to G.729.
g729ar8	CACELP voice compression at 8 Kbps according to G.729A.
g729ar8v	CACELP voice compression at 8 Kbps with VAD according to G.729A.

The difference between a PCM (p) connection and a transparent (t) or transparent D-compression (td) connection is that the D4 frame signaling bits are identified and processed as signaling information with PCM connections. PCM connections permit gain adjustment to be applied to the connection. Transparent connections treat all bits, including signaling bits, as data bits and disables any gain adjustment conversion that you may have specified.

The number in the type field indicates the ADPCM rates in Kbps. The "z" suffix indicates that 00 code level is used. Type a16 or c16 uses only 01, 10, and 11 binary codes to avoid long strings of zeros. Type a16z and c16z connections use the 00 code and are automatically configured to avoid ZCS lines (*Z).

addcon 7.2 beta 8.2 v

Description

Add a "v" type voice connection. This command connects channel 7.2 on node alpha to channel 8.2 on node beta. A prompt appears asking you to confirm the proposed connections.

Connection type is "v," Class of Service (COS) is "2," compression is VAD, and ownership is local. For an explanation of COS, see the cnfcos description in the "Optimizing Traffic Routing and Bandwidth" chapter. Because you are entering the addcon command at node alpha, the node alpha is the owner of the connection.

Table 6-5: addcon—Parameters

Parameter	Description
local channel	Specifies the local channel or set of channels to add. Right-angle brackets indicate a range of channels. Channel specification on a UVM has one more parameter than the specification on a CDP or CVM, as follows: For a CDP or CVM, the format for channel specification is slot.chan[-chan]. For a UVM, the format for channel specification is slot.line.chan[-chan]. Refer to the Cisco IGX Reference for a description of the UVM's lines. Note that, if you are using CAS switching with Model B firmware, line must be 1.
node	Specifies the name of the node at the other end of the connection. For a DAX connection (where channels on a node are connected to channels on the same node), use the local node name.
remote channel	Specifies the remote channel or set of channels to connect. Brackets indicate that a range of channels can be specified. Channel specification on a UVM has one more parameter than the specification on a CDP or CVM. For a CDP or CVM, the format for channel specification is slot.chan[-chan]. For UVM, the format for channel specification is slot.line.chan[-chan]. Access devices such as the Cisco 3800 use the following format for the remote channel specification: <slot.port> <access_device_connection_ID> where slot is the slot number of the FTC or FTM card, port is the port number, and access_device_connection_ID is in the range 1-252.
type	Specifies the voice connection type. Refer to Table 6-1 or Table 6-2 for voice connection types and compression. For connections to an access device such as the Cisco 3810, type can be one of the following: 24 Kbps or 32 Kbps ADPCM, LDCELP, or CACELP.

Table 6-6: addcon—Optional Parameters

Parameter	Description
avoid	Specifies the type of trunk for the connection to avoid. The default is no avoidance. The choices are: s avoid satellite trunks. t avoid terrestrial trunks. z avoid trunks using zero code suppression techniques that modify any bit position to prevent long strings of zeros.

Parameter

Description

avoid

Specifies the type of trunk for the connection to avoid. The default is no avoidance. The choices are:

s avoid satellite trunks.
t avoid terrestrial trunks.
z avoid trunks using zero code suppression techniques that modify any bit position to prevent long strings of zeros.

cnfchadv

Enables the adaptive voice (ADV) feature for individual channels. ADV must also be enabled at each node that terminates the connection. The channel-specific cnfchadv has no effect at nodes that do not support ADV enabled.

If the ADV feature is enabled for a channel with a "c" or "v" connections, VAD is automatically disabled on that channel when trunk bandwidth is available and enabled when trunk bandwidth is needed. If the Adaptive Voice feature is not enabled for a channel with a "c" or "v" connections, VAD is always turned on for that channel. In order for a voice ("c" or "v") connection to use ADV, both ends must have ADV enabled with the cnfchadv command.

Parameter	Description
channel	Specifies the channel or range of channels over which you specify Adaptive Voice.
e	Enables ADV (default).
d	Disables ADV.

cnfchdl

Configures the dial type for a channel or set of channels. The dial type may be inband, pulse, or user-configured. The user-configured option allows non-default timing values to be used. The parameters associated with the cnfchdl command are timing constants used to ensure that signaling pulses are not distorted in time by transmission through the network.

Dial type determines the signaling message timing for a connection. Dial type is ignored for DS0 data connections.
When you add an inband or pulse dial type to a channel, the channel configuration screen appears, showing the designated dial types for each channel.
When you add a user-configured dial type, a more detailed screen appears, showing the dial type as well as the signaling delay, minimum wink, interdigit times, and playout delay.

If you select inband, the node assumes that the A and B bits are not used for loop-disconnect dialing. Therefore, any change in signaling bit status goes in a packet to the far end of the connection.

If you select pulse, the transmitting node waits (normally 72 ms) after an A or B bit transition for another transition to arrive. If a transition arrives, the new transition goes into the same signaling packet that is sent to the far end of the connection. This step increases the delay of the signaling transition across the network but decreases the amount of trunk bandwidth used for signaling.

If the default timings are not correct for the network, you must configure the options. The dialing type should be set correctly. If a connection-designated pulse is used for inband signaling, a greater than necessary delay across the network results. If a connection-designated inband is used for pulse signaling, the relative timing of signaling transitions may be lost and so distort the pulses.

cnfchfax

Configures a channel on a UVM for either FAX detection or FAX relay. If you enable FAX detection, the UVM suspends voice compression when it detects a FAX or modem tone on the channel. For the duration of the FAX, transmission takes place at 64 Kbps.

FAX relay is a mechanism for compression the FAX transmission rate across a network to 9.6 Kbps.

To view the current configuration, use the dspchcnf command.

cnfchgn

Configures the amount of gain inserted by the IGX node for a given circuit line channel or range of channels. Gain can be configured between +6 dB and -8 dB. The input gain is inserted at the receive side of a voice card and is therefore applied before the signal is packetized by the card. The output gain is inserted at the transmit side of a voice card and is applied after the signal has been depacketized by the card. Gain is meaningless for channels that carry data.

cnfcond

Creates a conditioning template that specifies the bit patterns to be transmitted for each of the T1 and E1 timeslots and their A, B, C, and D signaling bits while the channel is in the failed state. Its purpose is to prevent the signaling bits from returning to the idle (on-hook) bit pattern during a channel failure and to force a known bit pattern (usually busy). If a connection fails and the template has been specified as the conditioning template for the failed connection, the data parameter in the template is transmitted in the channels timeslot, and the A, B, C, and D bits are processed according to the specified parameters.

A two-character sequence in the ID parameter field identifies the template. The Data Pattern field displays the pattern transmitted in the channels timeslot. The Signaling Pattern field displays the pattern transmitted in the channel's A, B, C, and D signaling bit positions. Each of the A, B, C, and D signaling bits are specified independently and may be held high or low or toggled to the on-hook condition for a short time then off-hook (the name of this latter action is a wink). You can control the timing of the bit-toggling by specifying the duration of winks in increments of 50 ms.

A typical failure response is for the node to:

1. Transmit idle characters in the channel's timeslot

2. Signal off-hook for a period of 2 seconds

3. Return permanently to the on-hook condition

Parameter	Description
id	Specifies the identifier of conditioning template. The identifier may be any two character combination of lowercase letters (a-z) and numeric digits (0-9).
data	Specifies an eight-bit binary string to use instead of the voice in the event the channel fails.
A bit B bit C bit D bit	Specifies the signaling sequence to be transmitted for these bits in the event of a channel failure. You can independently set each of these parameters. Each element in the sequence is expressed as a 1 or 0 (to indicate the logic state of the line) followed by a number in parenthesis to indicate the duration that the state remains on the channel. The duration number is expressed in 50 ms intervals. If you do not enter a duration value, the state remains the same indefinitely. For example, if <B> is set to 1(40); upon a channel failure, the B bit remains in the 1 state for 2 seconds (40 x 50 ms=2 seconds). For another example, <C> set to 0 would cause the C bit to be held permanently at 0 during a failed channel condition because no duration value is present. Note that you can specify a sequence of states by entering several states separated by slash symbols. The maximum number of states in a sequence is 5. For example, you could set <A> to 1(40)/0(20)/1 to vary the duration of the 0 and 1 states.

For another example, <C> set to 0 would cause the C bit to be held permanently at 0 during a failed channel condition because no duration value is present.

Note that you can specify a sequence of states by entering several states separated by slash symbols. The maximum number of states in a sequence is 5. For example, you could set <A> to 1(40)/0(20)/1 to vary the duration of the 0 and 1 states.

cnflnpass

Configures a pair of ports so that unprocessed channels go from a primary UVM to a secondary UVM. The cnflnpass command primarily applies to channels that use LDCELP or G.729 CACELP (although passthrough is possible on any type of connection except t-type or td-type). For a description of pass-through, refer to the UVM description in the Cisco IGX Reference.

To return ports to the non-passing configuration, execute cnflnpass with a 0 as the second argument.

Full Name

Configure line pass-through

Syntax

To configure pass-through, enter:

cnflnpass <primary line> <secondary line>

To remove pass-through from the primary and secondary lines, enter:

cnfvchtp

Configures an interface signaling type for a voice channel. Most standard signaling types are maintained by the node, but a custom template may be built by the user. If you enter the cnfvchtp command without a specific interface number, the system will present you with a list of valid interface types and their associated onhook and conditioning information.

To assign an interface type (and its associated onhook and conditioning information) to the channel or set of channels, enter the number of the desired interface type. As mentioned previously, type "1" requires user configuration. Interface type is ignored for "d" type connections.

cnfvchtp 15.5-8 1 X X - - b

Description

Configure a user configurable interface type for channel 15.1 to 15.8. The channel configuration screen shows that channels 5-8 of circuit line 15 now has a user-configured interface type with an Abit on-hook value of X, a B-bit on-hook value of X, an C-bit on-hook value of not used, D-bit on-hook value of not used, and conditioning template b.

Table 6-17: cnfvchtp—Parameters

Parameter	Description
channel	Specifies the channel or range of channels for the interface type configuration. For a CVM or CDP, the format is slot.channel[-channel]. For a UVM, the format for channel is slot.line.channel[-channel].
interface type	Specifies the number of the interface type to assign to the channel or range of channels. These types are listed in Table 6-18. The On-hook column has A bits on the left and B bits on the right. The conditioning column has different types of conditioning specified. If you designate interface type number 1 to indicate a user-configured interface type, the system prompts for: on-hook A, on-hook B, on-hook C (if applicable), on-hook D (if applicable), conditioning A, conditioning B, conditioning C (if applicable), conditioning D (if applicable), and conditioning template information. When the IPX or IGX receives A, B, C, and D bits corresponding to the on-hook values, that channel is known to be on-hook. If the A, B, C, and D bits do not correspond to the onhook values, that channel is known be off-hook
onhook A	Abit value for the on-hook state of a channel or set of channels.
onhook B	Bbit value for the on-hook state of a channel or set of channels.
onhook C	Cbit value for the on-hook state of a channel or set of channels.
onhook D	Dbit value for the on-hook state of a channel or set of channels. Possible values are: 1 + high 0 = low X= don't care ? = don't know - = not used
conditioning template	One of many predefined or user-defined conditioning templates in the range of 00000000 to 11111111. (See dspcond and cnfcond commands.) Each interface type, except for option 1, has a predetermined conditioning template associated with it. These represent the A, B, C, D bit values as well as the substitute PCM voice sample sent to the attached equipment in case the voice connection fails for any reason.

cnfxmtsig

Allows the node to pass A, B, C, and D channel signaling bits through unchanged, or to invert, or hold them at a given value for a CDP or CVM line. It affects signaling bits in the transmit direction (to the PBX or channel bank) in an E1 system. The command configures the transmit signaling. Channel signaling bit options are T (transparent), 0, 1, or I (invert). If signaling is set to "not used" (-) by cnfchtp, the following is maintained: A=1, B=1, C=0, D=1.

Table 6-28: dspcond—Parameters

Parameter	Description
identifier	Specifies the identifier of the template.

dspcons

Displays a summary of the connections on an IGX node. Table 6-29 shows the fields displayed in the dspcons screens.

The dspcons screen in Example 3 shows whether the Idle Code Suppression feature is enabled or disabled. The Idle Code Suppression feature provides a way to stop Fast Packet generation on an Nx64 super-rate PVC connection when the connected PBX has terminated a video call. Traffic on the data network will therefore be reduced. Bursty data will be able to use this unused bandwidth.

On the dspcons screen, data connections show the letters ICS under the Compress field if the connection has idle code suppression enabled or not. This feature is supported only on IGX platforms in Release 9.2. It is supported only on the UVM and CDP/CVM cards. The UVM model E and CVM/CDP model B revision E firmware are required to use the Idle Code Suppression feature in Release 9.2.

Table 6-29: Information in the dspcons Display

Fields	Description
Local Channel	The connection's channel at this node.
Remote Node Name	The name of the node at the other end of the connection.
Remote Channel	The connection's channel at the remote node.
State	The state of the connection(s) as follows: OK = Routed Down = Downed OK Downed = Waiting for onhook to occur to allow courtesy down to take place for connection(s) that have been courtesy downed using the dncon command. Failed = Unrouted, but trying
Type	The type of connection (v = voice, d = data, fr = Frame Relay, atfr = ATM to Frame Relay interworking, atfst = ATM to Frame Relay interworking with ForeSight, -fail = failed connections; data rate in Kbps for data).
Compression	The type of compression applied to the connection. The types of voice compression appear earlier in the chapter. The compression that applies to data connections is the purchased option called repetitive pattern suppression (RPS).
COS	The Class Of Service.
Loopback	A connection with a local loopback is indicated by a right parenthesis symbol between the Local Channel and Remote NodeName columns. A Frame Relay connection with a port loopback is indicated by a right bracket symbol between the Local Channel and Remote NodeName columns. A connection with a remote loopback is indicated by a right parenthesis symbol before the channel number in the Remote Channel column.
Local/Remote Abit	A bit status on the local and remote nodes if -abit option selected. Note that -abit is incompatible with -v, -d, and +d.

Last Command: dspcons

Table 6-30: dspcons-Optional Parameters

Parameter	Description
start channel	Specifies the channel to begin the display. The start channel on a CDP or CVM is specified as slot.channel. The start channel on a UVM is slot.line.channel.
node name	Specifies that only connections to this remote node from the local note be displayed. If no "nodename" is designated, connections from the local node to all other nodes are displayed.
connection type	Specifies that only connections of a certain type be displayed. If you do not add at least one argument to specify a particular connection type, all connections appear. When you enter the connection type on the command line, precede it with a hyphen (-). In some cases, you can add more than one connection type (with a space between), but not all compound arguments are compatible, so you may not always see the expected combination of types. The connection types are: -v displays only voice connections. -d displays only data connections. -f displays only Frame Relay connections. -abit shows Abit (nni) status. -fabit shows connections with failed Abit (nni) status. -fail shows only failed connections -siw shows service interworking connections. -atfr shows only network interworking connections.
+d	Causes the display to show the user-configured descriptor for the connection instead of the compression and ownership fields.

dspconst

Displays the status of the circuit line(s) and continues to display the status until you press the Delete key. While the display is on the screen, the status is automatically updated. The update frequency is one second for each circuit line being displayed. (For example, if only one line is displayed, the update frequency is once per second, if three circuit lines are displayed, the update frequency is once per three seconds.) Table 6-31 shows the connection type. The cnfchtp command must be correctly configured.

c	Clears the cache, or if you also enter the index parameter, clears the route cache specified by the index number.

dspsigqual

Displays the configuration for the A, B, C, and D bit signaling qualifiers for all channels. The only parameter is the starting channel. You set the values for these signaling bits with the cnfrcvsig and cnfxmtsig commands. Note that these signaling bit states are different from the states during circuit alarm (signaling conditioning).

During normal operation of the voice circuit, the A, B, C, and D signaling bits may be held at a fixed value (0 or 1), inverted (I), or passed through transparently (T). For the direction of the signals, the transmit direction is towards the PBX or channel bank. Receive is from the external equipment.
