The
Model 2701 receives channelized G.704 (n
x 64Kbps) or clear channel E1/G.703 (2.048-Mbps)
data from the telco's digital data network.
The Model 2701 terminates the G.703 telco
interface and converts the data for transmission
to a user-oriented serial (X.21, V.35, and
EIA-530 (V.36/RS422)) or 10Base-T (802.3)
Ethernet interface. The 2701 can connect
to a Router, FRAD, PABX or Multiplexer over its
serial interface at nx64kbps data rates
up to 2 Mbps, or directly to a 10-Mbps Ethernet
LAN.
The Ethernet ("LAN") version of
the Model 2701 supports an integrated 10Base-T
(802.3) Ethernet port with transparent
bridging capability for IP, IPX, DECnet,
NetBIOS and other layer-3 protocols.
The integrated Ethernet port reduces the
need for technicians to configure remote
devices, constantly update routing tables
and manage yet another box. Instead of purchasing
a router and an NTU for your small, remote
office locations, the 2701 attaches to the
LAN and intelligently bridges data traffic
to the large central site router through
the telco's leased line network. And,
the 2701 supports Fractional E1 (n x 64kbps),
which means that each office only purchases
the bandwidth they need for that remote
site. Now, remote PCs, workstations and
servers on Ethernet LANs can be connected
across a G.703/G.704 leased line network
with one low-cost NTU. Local management
of the 2701 NTU is available through simple-to-use
DIP switches. LEDs monitor the G.703 link,
Ethernet LAN for status and Loss of Sync.
The 2701 also includes toggle switches to
initiate V.54 BERT and remote loopback tests,
device and CPU status. In the Ethernet version
collision detection software provides diagnostic
information through the local LEDs or remotely
through the network management system (for
the rack version). For synchronous,
leased line connections for the last mile,
BetterBox® has the solution.
