Voice Connections

Voice Connections


The voice commands apply to the setting up, configuring, and statistical reporting for voice connections (including FAX). In addition to the command descriptions, this chapter describes how to set up the voice connection, configure voice redundancy, use VAD, and configure voice channel utilization.

Voice connections exist as ports on circuit lines that are supported by either a CDP in an IPX or a CVM or 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 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. (The upln and upcln commands have the same purpose.)

♦ cnfcassw

If the UVM must convert CAS or DTMF to CCS signaling messages for processing by a Voice Network Switch, use cnfcassw to configure the UVM for CAS switching. The UVM must be a Model C or higher.

♦ cnflnpass

For a UVM intended to carry voice traffic with Low Delay Code-Excited Linear Predictive Coding (LDCELP), cnflnpass configures the UVM lines for the pass-through feature. Refer to the Cisco IGX 8400 Series Reference for a description of pass-through. Before you can execute cnflnpass, you must up (upln) and configure (cnfln) the lines.

♦ 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. Options are inband (default), 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.

♦ cnfcondsc

Configures a connection descriptor for the channel.

♦ cnfrcvsig

Configures receive signalling for the channel.

♦ cnfxmtsig

Configures transmit signalling for the channel.

♦ cnfvchtp

Configures a voice interface type for the channel.

♦ cnfchutl

Configures the channel utilization (see the chapter titled "Optimizing Traffic Routing and Bandwidth").

♦ 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 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 then connecting them to the CPE through a Y-cable. Configure redundancy by using addyred.

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 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 Low Delay Code-Excited Linear Predictive Coding (LDCELP compression), you must have a second, connected UVM and configure the pair of UVMs for pass-through operation. If you attempt to add more than 16 LDCELP channels, the system reports the excess connections as failed upon conclusion of the addcon command, and dspcon for any excess connection shows a status of "ConnRJ" (connection rejected). Refer to the cnflnpass description in this chapter and the UVM description in the Cisco IGX 8400 Series Reference for a description of pass-through operation.

After you have established pass-through 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.

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 chapter titled "Optimizing Traffic Routing and Bandwidth.")

Table 7-2 describes what you enter for the type parameter for each rate and compression variable.

t

A t-connection carries 64 Kbps clear channel data traffic.

v

A v-connection is the same as "p" (above) but with voice activity detection (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.

The difference between a PCM (p) connection and a transparent (t) connection is that the D4 frame signalling bits are identified and processed as signalling information with PCM connections. PCM connections permit gain adjustment to be applied to the connection. Transparent connections treat all bits, including signalling 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 zeroes. 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 chapter titled "Optimizing Traffic Routing and Bandwidth." Because you are entering the addcon command at node alpha, the node alpha is the owner of the connection.

Table 7-5: addcon-Parameters
Parameter Description

local channel

Specifies the local 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 a UVM, the format for channel specification is slot.line.chan[-chan]. Note that if you have specified CAS switching with the cnfcassw command, the signaling channels are 25 on a T1 line and 16 on an E1 line.

node

Specifies the name of the node at the other end of the connection. For a DACS-type 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. Brackets indicate a range of channels. 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]. Note also that if you have specified CAS switching with the cnfcassw command, the signaling channels are 25 on a T1 line and 16 on an E1 line.

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 7-2 or Table 7-3 for voice connection types and compression.

For connections to an access device such as the Cisco 3800, type can be one of the following compression algorithms: a24, a32, or l16 (16 Kbps LDCELP).
Table 7-6: 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.

cnfchadv

Enables the Adaptive Voice feature for individual channels. The Adaptive Voice feature must also exist at each node that terminates the connection. The channel-specific cnfchadv has no effect at nodes that do not have Adaptive Voice.

If the Adaptive Voice 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 Adaptive Voice, both ends must have Adaptive Voice enabled with the cnfchadv command.

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 signalling pulses are not distorted in time by transmission through the network.

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

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

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 signalling, a greater than necessary delay across the network results. If a connection-designated inband is used for pulse signalling, the relative timing of signalling transitions may be lost and so distort the pulses.

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 signalling bits while the channel is in the failed state. Its purpose is to prevent the signalling 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 'Signalling Pattern' field displays the pattern transmitted in the channel's A, B, C, and D signalling bit positions. Each of the A, B, C, and D signalling 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 msec.

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 signalling sequence to be transmitted for these bits in the event of channel failure. Each of these four parameters may be set independently. 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 state is to be held on the channel. The duration number is expressed in 50 msec intervals.

For example, if <B> is set to 1(40); upon a channel failure, the B bit is held to the 1 state for a period of 2 seconds (40 x 50 msec = 2 seconds). If the duration value is omitted, the state is held permanently. So <C> set to 0 would cause the C bit to be held permanently to 0 during a failed channel condition.

A sequence of states can be specified by entering several states separated by slash symbols. A maximum of 5 states in sequence can be specified. For example, <A> set to 1(40)/0(20)/1 would cause, upon a failure of the c

Table 7-18: cnfuvmchparm-Parameters
Parameter Description

channel

Specifies the channel or range of channels.

value

"Value" consists of the following parameters:

VCU is the Voice codec unit. The value for this parameter is a noise level placed in a voice packet that is added in case a voice packet is dropped. The value you can enter is a multiplier for the base noise level of -10 dB. The range is 1 - 15 (multiplied by -10 dB). For example, if you enter 6, the level of noise placed in a replacement packet is -60 dB.

PIU is the PCM interface unit. This feature performs a resampling and injects noise in case of lost packets. The range is 1 - 15 (multiplied by -10 dB). For example, if you enter 6, the level of noise placed in a replacement packet is -60 dB.

VAD is the Voice Activity Detection threshold. If the deciBel level falls below the specified limit, no packets are transmitted. The range is 0 - 65535 and is a multiplier of -1 dB, but typical values are around 30-40.

Modem threshold is a threshold for modem tone detection. Below this threshold, the tone is ignored (or "not detected"). The range is 0-255 and is a multiplier of -1 dB, but typical values are around 30-40.

All the other values appear as numbered columns. These are placeholders reserved for future development.

cnfvchtp

Configures an interface signalling type for a voice channel. Most standard signalling types are maintained by the node, but a custom template may be built by the user. Entering the cnfvchtp command without a specific interface number, the system presents 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.

The channel configuration screen shows that channels 5-8 of circuit line 15 now has a user-configured interface type with an A-bit 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 7-19: 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 below. The Onhook 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: onhook A, onhook B, onhook C (if applicable), onhook 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 onhook values, that channel is known to be onhook. If the A, B, C, and D bits do not correspond to the onhook values, that channel is known be offhook

onhook A

A-bit value for the onhook state of a channel or set of channels.

onhook B

B-bit value for the on-hook state of a channel or set of channels.

onhook C

C-bit value for the on-hook state of a channel or set of channels.

onhook D

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