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
throughput of up to 1.544 Mbps. Time Division
Multiplexing (TDM) allows for channelization of up to 24
links over a single physical T1/FT1 interface.
DELTD-UI This port interface module provides both a T1 and DDS
interface that allows you to easily switch between the
two interfaces by changing the physical cabling and
reconfiguring the desired interface with either QuickSET
for the DELHW-UA or NetSight Element Manager.
For more information on these port modules, consult the appropriate hardware
documentation or your QuickSET for the DELHW-UA documentation.
NOTE
To configure the DELDI-UI and DELE1-UI, use the QuickSET application that was
shipped with your device. See your QuickSET for the DELHW-UA documentation for
more information.
