TANDBERG 880 MXP, 990 MXP, 770 MXP Bandwidth, Overview, Restrict, 56k, 221 or 2x64 2x56 Calling

TANDBERG 770/880/990 MXP

	Select SIP to ensure that the call is set up as an SIP call.
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 and 768 kbps on LAN
	Max:	512 kbps on ISDN-BRI
		2Mbps (1920 kbps, IP only)
	1472 kbps = 23B, IP only
	1152 kbps = 18B, IP only
	768 kbps	= 12B, IP only
	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
	* 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.

These types of calls are often referred to as

ƒH.221 calls

ƒ2x64 calls

ƒ2x56 calls

-as making 2 x 64 kbps or 2 x 56 kbps calls to the same system.

Place this type of call by:

ƒSet Network to ISDN

ƒSet Bandwidth to 128 kbps

ƒA field for the 2nd number pops up in Call Settings.
