Prestige 202 ISDN Router
IP Alias
This feature is described as the ability to partition a physical network into logical networks over the same
Ethernet interface. You can use three logical LAN interfaces via a single physical Ethernet interface, with the
Prestige acting as the gateway for all the LAN networks. You can also route packets from one network to
another and, it allows your Prestige to have extra IP addresses.
10/100MB Auto-negotiation Ethernet/Fast Ethernet Interface
This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust
appropriately, providing a faster data transfer on the Ethernet network as required.
ISDN Data Link Connection
The Prestige supports two types of ISDN Data Link Connection namely: point-to-multipoint and point-to-
point. When you select point-to-multipoint, the TEI value is assigned by negotiation with the switch. When
you select point-to-point, the TEI value will be assigned a unique value of 0.
ISDN Phone Bearer Capability
The Prestige supports two types of ISDN phone bearer capability namely: 3.1K and speech. You can set the
Phone bearer capability "3.1K" using the CI command [isdn param set bearcapb 0] and set the Phone bearer
capability "speech" using the CI command [isdn param set bearcapb 1].
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.
Extensive Analog Phone Support
The Prestige is equipped with two standard phone jacks for you to connect analog devices such as telephones
and FAX machines. It also supports supplementary services such as call waiting and 3-way calling.
Incoming Call Support
In addition to making outgoing calls, you can configure the Prestige to act as a remote access server for
telecommuting employees.
Outgoing Data Call Bumping Support
Call bumping is a feature that allows the Prestige to manage an MP (Multilink Protocol) bundle dynamically,
dropping or reconnecting a channel in a bundle when necessary. Previously, the Prestige did this for voice
calls only, but now with this new feature, the Prestige can drop a channel in an MP bundle if there is a data
packet to another remote node.
CLID Callback Support For Dial-In Users
CLID is an authentication method to identify a dial-in user. CLID callback is used as an ISDN toll saving
feature because the call can be disconnected immediately without picking up the phone.
