Chapter 1 Getting To Know Your Isdn Router; Features Of The Prestige - ZyXEL Communications Prestige 202 User Manual

1.1

Features of the Prestige

Time and Date Setting
This new feature allows the Prestige to connect to a time server in order to synchronize its system clock when
it is booting.
Call Scheduling
This feature allows the Prestige to manage and time a call to a remote node as well as set the call duration.
NAT (Network Address Translation)
ZyXEL's SUA (Single User Account) has now been replaced by the all new NAT support. NAT, RFC-1631)
is the translation of an Internet protocol address used within one network to a different IP address known
within another network. NAT supports five types of IP/port mapping. They are:
1. One to One: In One-to-One mode, the Prestige maps one local IP address to one global IP address.
2. Many to One: In Many-to-One mode, the Prestige maps multiple local IP addresses to one global IP
address. This is equivalent to SUA (i.e., PAT, port address translation), ZyXEL's Single User
Account feature that previous ZyXEL routers supported (the SUA Only option in today's routers).
3. Many to Many Overload: In Many-to-Many Overload mode, the Prestige maps the multiple local IP
addresses to shared global IP addresses.
4. Many to Many No Overload: In Many-to-Many No Overload mode, the Prestige maps each local IP
addresses to unique global IP addresses.
5. Server: This type allows us to specify multiple inside servers of different types behind the NAT.
ZyXEL is also proud to announce that NetMeeting is supported for both incoming and outgoing calls. For
outgoing calls, there is no special configuration needed but for incoming calls, set the NetMeeting server to
ports 1503 and 1720.
SNMP (Simple Network Management Protocol – version 1)
SNMP, a member of the TCP/IP protocol suite, allows you to exchange management information between
network devices. Your Prestige supports SNMP agent functionality that allows a manager station to manage
and monitor the Prestige through the network.
NOTE: SNMP is only available if TCP/IP is configured on your Prestige.
