Remote access with full access to customer LAN/WAN
A single remote support and administration TM 3.1 PC can administer a
local node through the ITG Management LAN or can administer a remote
node through the WAN. The remote access capabilities are provided
through a modem router that has access to any of the ITG Management
LANs. The Remote TM 3.1 PC connects to the ITG Management over a
PPP link and then communicates to the IP trunk cards in the same manner
as a local TM 3.1 PC on the IP Trunk 3.01 (and later) Management LAN.
The IP address provided by the modem router (for example, Nortel Netgear
RM356 Modem Router) to the remote TM 3.1 PC is configured in the
modem router and in the SNMP Manager's list of the IP trunk cards. All
management communications including alarms are sent over this channel.
In the second scenario, the support organization is denied access to the
customer LAN/WAN network for security reasons. See
access with no access to customer LAN/WAN" (page
