DL3100
T3 Access Multiplexer
DL3100E E3 Access Multiplexer
WAN access device allows
you to connect as many
as three routers or other
data terminal equipment
to T3 or E3 circuits.
They are ideally suited
for higher band-width applications.
Features:
T3 or E3 interfaces
Can be configured for
up to three HSSI or V.35
data ports SNMP
management
Extensive diagnostics
Downloadable code for
easy upgrades
E3 unit is clear-channel-capable, for interoperability
with E3
devices from other vendors
Product
Overview:
As demand for bandwidth
increases and the diversity of networking applications
challenges
you to link people to essential resources, you need the flexibility,
reliability, and cost effective-ness provided by the Digital Link DL3100 T3 Access Multiplexer
and the DL3100E E3 Access
Multiplexer.
The
carrier-class DL3100 an DL3100E offer up to three
high-speed DTE interfaces, user-programmable
bandwidth allocation, and
Simple Network Management Protocol for device
configuration and management.
Both units enable wideband data connections that
provide the power to meet the needs of carriers and enterprises.
The
DL3100 and DL3100E support a broad range of bandwidth-demanding
applications,such
as video imaging and transmission, router backbones,
and client/server applications.Both devices include extensive diagnostic capabilities for
local and remote fault analysis.
DL3800
T1 Inverse Multiplexer 
DL3800E E1 Inverse Multiplexer
DL3800
Inverse Multiplexer is a high-speed WAN
access device that allows you to connect
routers or other data terminal equipment
to multiple T1 or E1 circuits. By bundling
the circuits together, you can have broadband
access without having to pay extra for a
T3 link. The DL3800 T1 Inverse Multiplexer
takes the bit-stream from a router and multiplexes
it onto one to eight T1 lines, providing
aggregate data rates of up to 12 Mbps (8´T1).
Similarly, the DL3800E E1 Inverse Multiplexer
sends data at speeds up to 16 Mbps (8´E1).
The DL3800 is ideally suited for higher
band-width applications where T3 or E3 circuits
are not available or cost-prohibitive.
Application:
Broadband Access - Narrowband Budget
The DL3800 T1 Inverse Multiplexer and the
DL3800E E1 Inverse Multiplexer accepts data
from a router or other DTE device and multiplexes
the bit stream onto one through eight T1
or E1 circuits. Because the inverse multiplexing
process is completely transparent to the
attached equipment, the bundled lines appear as a
single, high-speed data link.
Automatic
Bandwidth Response:
If one of the T1 or E1 circuits connected
to the DL3800 falls below acceptable performance
levels,the DL3800 will remove the circuit from
service and automatically reduce the DTE
rate to correspond with the remaining lines.
Comprehensive
Network Management:
The DL3800 supports the industry-standard
Simple Network Management Protocol (SNMP
MIB
II). It also features a device-specific
enterprise MIB which allows you to configure,
monitor and control all significant operating parameters.
You can manage the unit via:
menu-driven, front-panel display
local VT-100 compatible terminal
Any popular SNMP management software,
including HP OpenView or SunNet Manager
Digital Link's WANview Network Management
System
Added
Features and Benefits of the DL3800:
Accepts up to a 31 ms differential delay
between circuits, ensuring reliable operation
in multiple-carrier
networks
A 16-character alpha-numeric readout
immediately indicates problems
A built-in self-test function automatically
evaluates the unit
User-selectable alarm parameters and
performance thresholds for alarm reporting
Built-in test loops
Integrated event log with non-volatile
memory
Fully compatible with Digital LinkÕs
DL3900 Broadband Access System, for high-density
hub applications.

DL5400
Multi Link Access Device 
This
equipment is designed for customers who
need more than a 1.5M bit/sec T-1 circuit,
but less than a 45M bit/sec T-3. Typically,
it is less expensive to buy up to eight
T-1s than to buy a T-3. Customers can
plug up to eight T-1s into the DL5400 and
attach the device to a LAN router via the
DL5400's 10/100 Ethernet port.
MLPPP
and MLFR will be standards, meaning customers
won't have to worry about whether there
is another Digital Link box at the service
provider end of the T-1 connection, the
company claims. The product should work
with any standard-based gear from other
vendors. With that in mind, Digital Link
has tested the DL5400 with a Cisco 7500
router equipped with MLPPP, and Digital
Link says they work together. Cisco has
not certified the tests. In addition, Digital
Link and Ascend have agreed to work to make
their implementations of the emerging MLFR
specification interoperate.
After
proving interoperability with these two
vendors, Digital Link will be on its way
to supporting multilink services from carriers
that already use Cisco and Ascend carrier
gear, according to Bettina Tratz-Ryan, an
analyst at DataQuest.
Late
in 2000, Digital Link plans to add a T-3
interface to the DL5400. The interface
will be divided into T-1 channels so that
with the cooperation of a service provider,
customers can use some of the bandwidth
to connect to an ISP and some to connect
to another corporate site. The company intends
to develop support for inverse multiplexing
over ATM, another industry standard for
bonding T-1 pipes -only in this case the
circuits are ATM. Digital Link also plans
to support digital subscriber line technology
so customers can use the DL5400 as a DSL
modem.
