Getting to Know Your ISDN Router

1.1Features of the Prestige

Time and Date Setting

This all new feature allows the Prestige to connect to a time server to synchronize its system clock when it is booting.

Call Scheduling

The call scheduling feature allows the Prestige to manage a remote node and dictate when a remote node should be called and for how long

NAT(Network Address Translation)

ZyXEL’s SUA (Single User Account) has now been replaced by the all new NAT support. NAT (Network Address Translation - 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 the 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.

ISDN Basic Rate Interface (BRI) Support

The Prestige supports a single BRI. A BRI offers two 64 Kbps channels, which can be used independently for two destinations or be bundled to speed up data transfer.
