TANDBERG 7000 MXP

	Select ISDN to ensure that the call is set up as an ISDN call.
	Select H.323 to ensure that the call is set up as an H.323 call.
	Select SIP to ensure that the call is set up as an SIP call.
	Bandwidth decides the quality of the video picture.
Bandwidth
	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)
		4Mbps(4096 kbps, IP only)

4096 kbps = 4 Mbps, IP only

3072 kbps = 3 Mbps, IP only

2560 kbps = 2,5 Mbps, IP only

1920 kbps = 2 Mbps, 30B

1472 kbps = 23B

1152 kbps = 18B

768 kbps	= 12B
512 kbps	= 8B
384 kbps	= 6B
320 kbps	= 5B
256 kbps	= 4B
192 kbps	= 3B
128 kbps	= 2B, Bonding/H.221
64 kbps	= 1B, H.221
H0	= 1xH0, 384 kbps, PRI only

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

Restrict	A restricted call uses 56kbps channels rather then the default unrestricted
(56k)	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.

H.221 or 2x64 (2x56) Calling

Some older or low end video systems do not have the ability to make bonded ISDN calls. In these cases it is necessary to dial both ISDN numbers separately to call those systems.
