WAN Configuration

Port interface modules available for the DELHW-UA include:

DELDS-UI

DDS is Digital Data Services, a digital network that

 

supports data rates of 56Kbps or 64Kbps. The DDS

 

service provides users with dedicated, two-way

 

simultaneous transmission capabilities operating at

 

transfer rates up to 64 Kbps. This port module comes

 

with a built-in CSU/DSU.

DELDI-UI

The DI (Drop-and-Insert) port interface module provides

 

a T1 interface through a front-panel RJ45 port and

 

includes a built-in CSU/DSU for direct connection to a

 

T1 line. The DELDI-UI provides Full T1 or Fractional T1

 

using 56 or 64 Kbps Time Slots. It also provides a second

 

Drop-and-Insert interface that allows more than one

 

device, such as a PBX, to share a single T1 connection.

DELE1-UI

This port interface module provides an E1 interface

 

through a front-panel RJ-45 port and includes a built-in

 

CSU/DSU for direct connection to an E1 line. It provides

 

Full E1 or Fractional E1 using 56 or 64 Kbps Time Slots

 

with a total throughput of up to 2 Mbps. Time Division

 

Multiplexing (TDM) allows for the channelization of up

 

to 31 links of a single physical interface.

DELST-UI

This port interface module provides an ISDN 128 Kbps

 

Basic Rate Interface (BRI) and is designed for an ISDN

 

back-up link for a frame relay or leased line. In the

 

United States and Canada, Network Terminator

 

equipment (NT1) is required to provide an interface

 

between the DELST-UI and the ISDN line.

DELSY-UI

Provides a synchronous serial connection of up to 2.048

 

Mbps to external communications equipment (an

 

external CSU/DSU is required). An external CSU/DSU

 

is required; the following electrical interfaces are

 

supported (consult your hardware documentation for

 

cable pinout information):

 

EIA-RS449

 

V.35

 

EIA-RS232D

 

X.21

 

EIA-RS530

 

EIA-530A

 

RS530 ALT A

 

RS530A ALT A

DELT1-UI

Provides a T1 interface through a front-panel RJ45 port

 

and includes a built-in CSU/DSU for direct connection to

 

a T1 line. The DELT1-UI provides both Full T1 or

 

Fractional T1 using 56 or 64 Kbps Time Slots, with a total
