Step 2 Add the connection with the addcon command. The above configuration must have been completed at each end before the connection can be added.
Configuring Voice Channel Redundancy
Voice channels can be configured for redundancy by installing two identical sets of data front and back card pairs in adjacent slots and connecting to the customer's line through a Y-cable.
- Use the addyred command to establish the redundant connection between the two card sets.
- Use the delyred command to remove redundancy from a redundant pair.
Using VAD and Configuring Voice Channel Utilization
Bandwidth savings from using VAD will not be realized to the fullest extent unless the utilization of the voice channels is set to a reasonable value. The utilization for voice channels is configured using the cnfchutl command.

addcon
Establishes the channel connections between nodes in the network. Connections can be added to any node slot equipped with a CDP or CVM. Before adding the connection, determine the compression type to be used for the connection. The table in this command definition delineates each compression type.
When connecting sets of voice channels, you do not have to specify the full channel set for this end of the connection. You only have to designate 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, channel 13.2 is connected to channel 12.6 and so on.
Connections are added with default "class of service" (COS) values, which may be changed using the cnfcos command. The default values are: COS = 8 for c, v, and a connections, COS = 0 for t and p connections. Entering "*s" to avoid routing a voice connection over a satellite path avoids the long delays typical with these connections. The other choices for route avoidance are not generally useful for voice connections. The following are possible connections:
Table 7-2 :
| CDP or CVM
|
a32 a24 a16
|
ADPCM only
|
Uses ADPCM only. Can select 32 Kbps, 24 Kbps, or 16 Kbps compression. Compressed code avoids all zeros and can be used on lines with no other zero code suppression techniques. Modified 16 Kbps compression.
|
|
|
a16z
|
ADPCM on zero suppressed lines
|
Standard 16 Kbps ADPCM only. Compressed code can have strings of zeros and must be used on lines that do not use ZCS (for example, that use B8ZS).
|
|
|
a32d
c32d
|
ADPCM for FAX
|
Specifies 32 Kbps specially optimized for FAX. c32d incorporates Voice Activity Detection (VAD).
|
|
|
c32 c24 c16
|
VAD and ADPCM on zero suppressed lines
|
Uses both ADPCM and VAD. Can select 32 Kbps, 24 Kbps, or 16 Kbps ADPCM compression. Compressed code avoids all zeros and can be used on lines with no other zero code suppression techniques. 16 Kbps compression is non-standard.
|
|
|
c16z
|
VAD and ADPCM
|
Uses a standard 16 Kbps ADPCM compression and Voice Activity Detection. Similar to a16z. Compressed code can have strings of zeros and must be used on lines that do not use ZCS (for example, that use B8ZS).
|
|
|
p
|
PCM only
|
A p-type connection carries 64 Kbps PCM voice and supports A-law or mu-law encoding and conversion, level adjustment (gain/loss), and signalling.
|
|
|
v
|
PCM and VAD.
|
No ADPCM compression but VAD enabled. Approximately 2:1 compression.
|
|
|
t
|
Transparent
|
Connection carrying 64 Kbps clear channel data traffics.
|
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 may be specified.
The number contained in the CDP or CVM type 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. Channel 7.2 on node alpha will be connected to channel 8.2 on node beta. The connections are highlighted on the screen. A prompt appears asking you to confirm these connections.
Connection type is "v", "class of service" (COS) is "2" (See cnfcos command), compression is VAD, and ownership is local. Because the addcon command was entered at the node alpha, the node alpha is considered the "owner" of the connection.

cnfchadv
Enables the Adaptive Voice feature for individual channels. The Adaptive Voice feature must also be equipped at each node terminating the connection. If Adaptive Voice is not equipped for given nodes in the network, the channel specific Adaptive Voice disable/enable command (cnfchadv) has no effect at these nodes.
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.
- Dial type determines the signalling 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 signalling delay, minimum wink, interdigit times, and playout delay.
If inband is chosen, the node assumes that the A and B bits are not used for loop-disconnect dialing. Therefore, any change in signalling bit status is sent as a packet to the far end of the connection.
If pulse is chosen, the transmitting node waits (normally 72 msec) after an A or B bit transition for another transition to arrive. If one does, the new transition is incorporated into the same signalling packet that is sent to the far end of the connection. This 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, they may be set with the user configured option. The dialing type should be set correctly. If a connection designated pulse is used for inband signalling, delay across the network will be greater than necessary. If a connection designated inband is used for pulse signalling, the relative timing of signalling transitions may be lost, distorting the pulses.

cnfchgn
Configures the amount of gain inserted by the IPX or IGX mode 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 CDP or CVM circuit line and is therefore applied before the signal is packetized by the CDP or CVM. The output gain is inserted at the transmit side of a CDP or CVM circuit line and is applied after the signal has been depacketized by the CDP or CVM. Gain is ignored for channels used in data connections.

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 (this process is called a wink). The timing of toggling the bits can be controlled by specifying the duration of winks in increments of 50 msec.
A typical failure response is for the node to:
- Transmit idle characters in the channel's timeslot
- Signal off-hook for a period of 2 seconds
- Return permanently to the on-hook condition.

|
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

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 circuit 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.
