Connection Management Messages

All connection features use the connection management messages shown below.

Connect

Establish a two-way connection between the two specified channels. If there is no active call up for the B channel, a seizure will be generated on that channel and the voice path will be connected once seize ACKs have been met.

Connect With Pad

Establish a two-way connection between the two channels, while maintaining the specified dB gain/loss adjustment for the duration of the connection.

Connect With Data

• Connect With Data (A, B) (2-Way)

Establish a two-way connection between two Common Channel Signaling (CCS) channels. If the terminating channel is not idle after seizure, the alerting and connect indications propagate to the incoming side, and the message’s data specification is sent to the incoming CCS channel.

The following features are also supported:

• Canceling digit collection

• Playing call progress tones

• Voice path connection

• Dynamically configuring release modes

Park Channel

Park one or both channels involved in a connection. To park only one, set A and B to the same span/channel. When a channel is parked, it is not associated with any other channel and silence is transmitted. The channel may be used in a subsequent connection or it may be released later.

Release Channel

Release a single channel or a connected pair of channels. A Channel Released message is returned by each channel when the release is completed. If only one of the connected channels is released, the other channel is parked automatically.

Connect One-Way Forced

Establish a one-way connection between two channels. Channel A is the source channel (talk only) and channel B is the destination channel (listen only).

Channel A may be in any state except Idle, while Channel B can be in any state except Out of Service, and it cannot be in the process of clearing. This connection is transparent to Channel A, and it is torn down only if Channel B is released by the host or by the distant end.

Connect One-Way to Conference

Establishes a one-way (listen only) connection between the channel specified and the previously created conference specified. The channel can be in any state except Out of Service, and it cannot be in the process of clearing.

Connect to Conference

Adds the specified channel to the specified conference, which already exist. The channel to be added to a conference can be in any state except Out of Service, and it cannot be in the process of clearing.

Sub-Rate Connection Management

This message is used to establish and teardown subrate connections. Both channels must be out of service before the connection is established.
