Using the Clear Channel Protocol

The default protocol for the J-ONE card is Clear Channel. To use Clear Channel, you must assign Logical Span IDs on the J-ONE card before bringing it into service. The channels are ready for call processing when the host receives DS0 Status Change messages indicating that the channels are in service.

Limitations for J-ONE using Clear Channel Protocol

• Preprogrammed call control instruction lists (inseize or outseize) are not supported

• The Channel Parameter Query message is not supported for
J-ONE channels

• The Outseize Control message supports only the following ICBs:

• Seize

• Send Host Acknowledge

• Wait for Host Control

• Wait for Host Control with Answer

Signaling technique where the full channel bandwidth is used for data transmission, while the framing and control bits (signaling) use a separate channel. No control or signaling is performed on this path. See B8ZS and ZBTSI.
Range of channels provided by T1 or E1 transmission service. A physical span is a group of channels taking up a single physical wire. A logical span is a group of channels taking up less than a single logical wire, or carried over more than one physical wire.
Incoming call setup during real time call processing on a specific channel.
Outgoing call setup during real-time call processing on a specific channel.
A computer, attached to the Excel platform through an RS-232 or Ethernet link, from which you run the telecommunications application that controls the Excel platform.
