modem router for remote
access
Management and support of the ITG network depend on IP networking
protocols including SNMP, FTP, and Telnet. A modem router should be
installed on the Meridian 1 site management and signalling LAN (called the
embedded LAN or E-LAN as opposed to the customer's enterprise network
or C-LAN) in order to provide remote support access for ITG and other
IP-enabled Nortel Networks products. The Nortel Networks Netgear RM356
modem router integrates the functions of a V.90 modem, a PPP remote access
server, an IP router, and a 4-port 10BaseT Ethernet hub, and provides a range
of security features that may be configured so as to comply with the
customer's data network security policy.
Note: Do not install a modem router on the E-LAN without the explicit
approval of the customer's IP network manager. The RM356 modem
router is not secure unless it is configured correctly according to the
customer's network security policy and practices.

• RM356 manager password.
• CLID for dial-in user authentication (requires C.O. line with Calling
