ISDN 2 B-Channel Transfer

This ISDN PRI 2 B-Channel Transfer feature allows the UNIVERGE SV9100 to receive a call on one

B-Channel and transfer it back out on a second B-Channel (Trunk-to-Trunk transfer on the telco side).

When the transferred call connects, both of the B-Channels are then released and available for either

making or receiving another call. This feature provides more efficient use of B Channels on an ISDN

PRI by allowing a customer to transfer calls without tying up their B Channels for the duration of the call.

The bearer capability of two calls must be "Speech, 3.1-kHz Audio, Unrestricted Digital

Information" or compatible.

This feature is not supported with Automatic Transfer.

This feature is not supported with Unsupervised Conference.

This feature is only supported with a Manual Transfer.

This feature is only supported when both trunks are ISDN/PRI and the bearer capability of

the two trunks meet the same service requirements.

Trunk-to-Trunk programming must be enabled for this feature to work.

Both ISDN/PRI trunks must reside in the same system for this feature to work.

This feature is available if the Telco Service Provider supports this feature.

This feature is available in the following case:

At least one call to be transferred is:

answered (outgoing from the SV9100)

answered (incoming to the SV9100)

And the other call is:

answered (outgoing from the SV9100)

answered (incoming to the SV9100)
