Cisco TelePresence ISDN Link
Contents Introduction
H320 configuration
H320 DefaultCall Restrict
A restricted call uses 56 kbps channels rather than the default unrestricted 64 kbps channels.
Some older networks (primarily in the uSA) do not support 64 kbps channels and require
the use of restricted 56 kbps calls. By default, the system will dial an unrestricted call and
downspeed to 56 kbps if necessary. Restricted mode can be selected when making a call.
<Off/On>
Value space:
Off: Set to off to disable restricted calls by default.
On: Set to on to force restricted (56 kbps) calls by default.
H320 Encryption
Set the encryption mode for the communication between the endpoint and the H.320 side
interface (PRI/BRI/Net). the endpoint encryption status does oNLY reflect the encryption
status for the SIP transport leg between the endpoint and the ISDN Link. For more details on
encryption, see the "About audio and video encryption" section in the Appendices.
<Off/On/BestEffort>
Value space:
Off: the system will never use encryption on H.320 side.
On: the system will always use encryption H.320 side. No audio/video media is conveyed
until encryption with peer H.320 device is established.
BestEffort: the system will use encryption on H.320 side whenever possible. A call will start
without encryption, and if an encryption session with peer H.320 device is established, it will
switch automatically to encrypting media traffic.
H320 NetType
Defines the network type to use for H.320 calls.
<BRI/PRI/External/G703>
Value space:
BRI: Select BRI for the BRI network.
PRI: Select PRI for the PRI network.
External: Select external for the external network (Net/V.35).
G703: For test purpose only.

Status information
Rebonding is used to re-establish H.320 calls if corrupted data is received for a longer period
(10 - 15 sec).
<Off/On>
Value space:
Off: Some manufactures do not support this feature. By setting Rebonding to off this
functionality will be disabled.
On: Set to on to enable rebonding. the default value is on.
Relaxed bonding timer is used when B channels requires additional time before they can
become transparent.
<Normal/Relaxed>
Value space:
Normal: the default value is Normal.
Relaxed: Relaxed bonding timing should be used with applications where the B channels
use some additional time before they become transparent, like external encryption devices
etc.
Select if ISDN Link can downspeed current calls when all available bandwidth is in use, and
another outgoing call is requested from paired codec. Default value: on.
<On/Off>
Value space:
On: Downspeed available.
Off: Downspeed ot available.
