Cisco TelePresence ISDN Link
Contents Introduction
Network configuration
Network [1..1] Assignment
Define how the system will obtain its IPv4 address and the default gateway address. this
setting only applies to systems on IPv4.
<Static/DHCP>
Value space:
Static: Set the network assignment to Static and configure the static IPv4 settings (IP
Address, Gateway, SubnetMask).
DHCP: the systems addresses are automatically assigned by the DHCP server.
Network [1..1] IPStack
Select which internet protocols the system will support.
Note: even if IPv4 is selected, the ISDN Link will use IPv6 link for local traffic with the paired
codec when operating in auto pairing mode (default). It is important that the paired codec also
allows IPv6 link for local traffic, otherwise it will fail to pair with the ISDN Link.
<IPv4/IPv6>
Value space:
IPv4: IP version 4 is supported.
IPv6: IP version 6 is supported, and the IPv4 settings (IP Address, IP Subnet Mask and
Gateway) will be disabled.
Network [1..1] MTU
Set the ethernet Mtu (Maximum transmission unit).
Note: When operating in auto pairing mode (default), Mtu size must not be set below 1280.
this is due to use of IPv6, which requires minimum Mtu to be 1280 bytes.
<576..1500>
Value space:
Range: Select a value from 576 to 1500 bytes.

Getting started Software upgrade
Network [1..1] RemoteAccess Allow
Network [1..1] DNS Domain Name
"MyVideoSystem", this will result in the DNS lookup "MyVideoSystem.domain.com".
Network [1..1] DNS Server [1..3] Address
Network [1..1] IPv4 Address

Status information
Filter IP addresses for access.
Note: When operating in auto pairing mode, ssh is used for communication between the codec
and ISDN Link (pairing and web access from codec). this communication takes place with IPv4
and/or IPv6 and IPv6 link local addresses. If remote access is configured incorrectly or there
are changes to the network infrastructure, you may need to connect to the serial port to regain
remote access.
<S: 0, 255>
Value space:
Format: String with a maximum of 255 characters, space separated IP addresses or an IP
range.
DNS Domain Name is the default domain name suffix which is added to unqualified names.
example: If the DNS Domain Name is "domain.com" and the name to lookup is
<S: 0, 64>
Value space:
Format: String with a maximum of 64 characters.
Define the network addresses for DNS servers. up to 3 addresses may be specified. If the
network addresses are unknown, contact your administrator or Internet Service Provider.
<S: 0, 64>
Value space:
Format: String with a maximum of 64 characters.
enter the static IPv4 network address for the system. only applicable if the Network Assignment
is set to Static.
<S: 0, 64>
Value space:
Format: only the valid IP address format is accepted. Any IP address that contains letters
(192.a.2.0) or unvalid IP addresses (192.0.1234.0) will be rejected.
