DI-304/DI-304M ISDN Remote Router

Ease of Installation

Your DI-304/DI-304M is a self-contained unit that is quick and easy to install.
Physically, it resembles an external modem; however, it is a combination ISDN
router and Ethernet switch, and it uses twisted-pair Ethernet cables to connect to the
host network.

Built-in Switch

A dual-speed NWay switch, the DI-304/DI-304M provides four ports for connecting
network end nodes—single-user computers, servers, bridges, other routers, etc.—
through standard “straight-through” twisted-pair cables and one port for making an
“uplink” connection to another hub or switch through the same type of straight-
through cable used to connect end nodes.

ISDN Basic Rate Interface (BRI)

Using a standard S/T the DI-304/DI-304M supports DSS1 ISDN switches. The two
ISDN B-channels can be used independently for two destinations, or they can be
bundled together for one high-bandwidth connection supporting bandwidth-on-
demand.

Standard Phone Jacks (Just for DI-304M)

The router is equipped with two standard phone jacks for connecting telephones, fax
machines, or modems. This allows the ISDN line to be used for voice as well as data
calls.

Dial On Demand

The Dial On Demand feature allows a DI-304/DI-304M to automatically place a call
to a Remote Node whenever there is traffic coming from any workstation on the
LAN (Local Area Network) to that remote site.

Bandwidth On Demand

Bandwidth-on-Demand (BOD) for ISDN Interface: As the ISDN BRI interface has
two independent B channels, the BOD mechanism allows you to automatically
add/drop a B channel according to data traffic throughput.

Full Network Management

The DI-304/DI-304M incorporates SNMP (Simple Network Management Protocol)
support and menu-driven network management via a Telnet connection or an
embedded Web configuration program.

PPP Security

The DI-304/DI-304M supports PAP (Password Authentication Protocol) and CHAP
(Challenge Handshake Authentication Protocol).
