Bandwidth

Bandwidth decides the quality of the video picture.

When set to Auto the system will establish a connection using a proper bandwidth for the call, typically 384kbps for ISDN calls and 768kbps for IP calls.

When set to Max the system will set up the call with maximum bandwidth depending on the selected network.

Overview*

Auto:	384 kbps on ISDN/768 kbps on LAN
Max:	768 kbps on ISDN-BRI
	1472/1920 kbps (23/30Ch) on ISDN-PRI (T1/E1)

1920 kbps = 2 Mbps, 30B

1472 kbps = 23B

H0	= 1xH0, 384 kbps, PRI only

* Note that some software versions and networks do not support all channel selections.

Restrict (56k)

A restricted call uses 56kbps channels rather then the default unrestricted 64kbps channels.

Some older networks (primarily in the USA) do not support 64kbps channels and require the use of restricted 56kbps calls. By default the system will dial an unrestricted call and downspeed to 56kbps if necessary.

To force a restricted call, choose Restrict (56k) On.
