Displaying ISDN port utilization

For each ISDN port, you can view details of any port ac tivity for each ISDN channel. To display ISDN port

utilization details, go to ISDN > ISDN ports.

A message shows the status of ISDN layers 1 (physical) and 2 (D-channel). The same information is

shown in the ISDN Status page.

Note that if the ISDN Gateway is in leased line mode, there will be no s tatus for layer 2.

The following information is displayed for each channel of every ISDN port:

Field Field description

#

The ISDN channel number.

Activity

Whether or not this channel on this port is currently active. Activity is one of:

 inactive: not in use.

 active (data): in use. A voice and video call is taking pl ace and is using this

channel.

 active (voice): in use. An audio-only call is taking place and is using this

channel.

Direction

If the channel is active, the direction of the call is displa yed. Either:

 inbound: for calls to the ISDN endpoint.

 outbound: for calls from the ISDN endpoint.

Calling party

The identity of the endpoint that initiated the call (dependi ng on what that endpoint

has provided):

 for IP-ISDN calls (that is, outbound calls), this is the nam e of the H.323

device, the telephone number, or "Cisco TelePresence I SDN Gateway".

 for ISDN-IP calls (that is, inbound calls), th is is the telephone number of the

endpoint that made the call.

Called party

The number that was dialed by the calling party. Note that if the ISDN Gateway is in

leased line mode, there will be no called part number ava ilable.

For each port there is an Activate D-channel now button that is only active if layer 1 is up and layer 2 (D-

channel) is not. If neither or both are up for a port, the butto n is disabled for that port. Click the button to

bring up the D-channel.

Note: Typically, you need never do this because the ISDN Gateway automatically tries to bring up the D -

channel periodically. Also clicking the button is not guar anteed to work.
